Fire Limitation Blanket Normative Annex | DVM
Normative Annex for Fire Limitation Blanket Product Claims
This Normative Annex is part of the DVM Fire Limitation Blanket Reference. It provides evidence-based rules for presenting technical characteristics, intended applications, conformity statements, test documentation and commercial claims on professional product pages.
The annex applies to products commonly described as Fire Limitation Blankets, EV fire blankets, electric vehicle fire blankets, vehicle fire blankets, car fire blankets, battery fire blankets or fire containment blankets.
This annex defines a consistent structure for professional product claims and supporting evidence within the DVM Fire Limitation Blanket Reference.
It is intended for manufacturers, distributors, OEM customers, private-label partners, product managers, quality managers, technical writers, marketing teams and professional buyers reviewing EV fire blanket product information.
The technically preferred term throughout the DVM Reference is Fire Limitation Blanket. Alternative search terms are used where they help international users find the product category, but they should not change the documented function of the product.

DVM Normative Annex for Fire Limitation Blanket Product Pages
Technical basis: Informed by DIN SPEC 91489:2024-11
Document type: Evidence-based product-positioning and documentation reference
Primary application: Professional, distributor, OEM, private-label and international product pages
This Normative Annex is part of a technical reference and procurement framework developed by DVM International B.V.
It is not a DIN, EN, CEN, ISO or government-issued standard. It does not create separate product certification, constitute a legal conformity- assessment procedure or replace DIN SPEC 91489:2024-11, applicable legislation, product-specific test reports, risk assessments or the manufacturer’s instructions.
DIN 91489:2026-02 has been published as a draft successor. The applicable edition and contractual basis should therefore be verified whenever claims are made about testing, conformity or certification.
The term “normative” describes the rules applied within the DVM Fire Limitation Blanket Reference. It does not mean that this annex has been issued by an official standards organisation or regulatory authority.
A1. Zweck
This annex provides standardised, procurement-grade wording and structure for professional Fire Limitation Blanket and EV fire blanket product pages.
It is intended to:
- prevent ambiguous, exaggerated or unsupported claims;
- promote consistent presentation of technical characteristics;
- connect each material claim with suitable supporting evidence;
- distinguish technical terminology from common search terminology;
- support consistent OEM and private-label positioning;
- improve comparability between products and suppliers;
- support documentary review against DIN SPEC 91489;
- reduce confusion between testing, conformity and certification;
- avoid implying that the blanket actively extinguishes a battery fire.
Use of wording from this annex does not by itself demonstrate product conformity.
Every statement must correspond with the actual product specification, dimensions, weight, materials, coatings, seams, loops, folding method, packaging, markings, instructions, language versions, traceability and applicable test evidence.
A product claim should only be published when it is accurate for the exact product configuration being offered and can be supported by relevant, objective and traceable evidence.
A2. Scope of Product-Page Review
This annex applies to product information presented through:
- manufacturer and distributor websites;
- webshops and online catalogues;
- technical product pages;
- digital and printed data sheets;
- tender documentation;
- OEM and private-label presentations;
- commercial quotations containing technical claims;
- product comparison pages;
- marketplace listings;
- approved packaging or product artwork;
- training, inspection and application documents;
- social-media or advertising content containing technical claims.
The same evidence principles should be applied regardless of whether the information is published by the manufacturer, importer, distributor, private-label owner or another party in the supply chain.
A3. Fire Limitation Blanket and EV Fire Blanket Terminology
The official technical term used throughout the DVM Reference is:
Fire Limitation Blanket
Common international search and commercial terms include:
- EV fire blanket;
- electric vehicle fire blanket;
- electric car fire blanket;
- vehicle fire blanket;
- car fire blanket;
- EV battery fire blanket;
- battery fire blanket;
- fire containment blanket;
- vehicle fire containment blanket;
- fire suppression blanket for electric vehicles.
These terms may be used for discoverability where the context remains technically accurate.
“This Fire Limitation Blanket, commonly searched for as an EV fire blanket or electric vehicle fire blanket, is intended to help limit the development and spread of heat, flames, smoke and burning particles.”
Search terminology should never be used to imply that the product actively extinguishes a traction-battery fire or stops thermal runaway.
A4. General Rules for Product Claims
Product-page statements should be:
- specific and capable of objective verification;
- applicable to the exact model being offered;
- consistent with the available test and technical documentation;
- consistent with packaging, instructions and application videos;
- limited to the scope demonstrated by the evidence;
- written without unjustified absolute or universal claims;
- appropriate for the intended country and application;
- reviewed after relevant product, packaging or standard changes;
- clear about whether evidence concerns a material or complete product;
- clear about whether a statement concerns testing or certification.
A claim should not be derived from a material or fabric certificate alone where the statement relates to the performance of the complete Fire Limitation Blanket, including dimensions, seams, loops, folding, packaging, deployment and instructions.
A5. Permitted Product-Positioning Statements
A5.1 Product-category statement
“Professional Fire Limitation Blanket for electric vehicles.”
“EV fire blanket designed to help limit heat, flames, smoke and fire spread around an electric vehicle.”
The technically preferred product name should remain visible even where a common search term is used.
A5.2 Intended-function statement
“Designed to help contain heat, flames, smoke and burning particles and to limit fire development and spread around an electric vehicle.”
Wording such as “helps contain,” “helps limit” and “supports incident control” is preferred to wording that guarantees an outcome.
A5.3 DIN SPEC 91489 conformity statement
“Conforms to DIN SPEC 91489:2024-11 for the identified product model.”
This wording should only be used where the available evidence supports the applicable requirements for the complete product being supplied.
It should not be used solely on the basis of:
- a fabric or coating report;
- a general supplier declaration;
- an unrelated or unidentified product test;
- a report covering a different size or construction;
- partial testing presented as complete-product conformity;
- an application video without supporting technical evidence.
A5.4 Testing statement
“Independently tested against the applicable requirements of DIN SPEC 91489:2024-11.”
The testing organisation may be named where the statement is accurate and supported by the applicable documentation.
The wording should not imply certification unless an actual certification scheme and certificate apply.
A5.5 Certification statement
“Certified under [identify the applicable certification scheme, certificate and product scope].”
A test report does not automatically constitute product certification.
A5.6 Dimensions and weight statement
“Finished dimensions: [X] × [Y] metres. Product weight: [Z] kg.”
The values should refer to the finished product as supplied and should be supported by product specifications, verified measurements or test reports.
A5.7 Deployment statement
“The complete product has been application-tested on the identified reference vehicle using the supplied packaging, folding method and loop arrangement.”
Where the number of persons or application time is stated, the exact technical-rule edition and test evidence should support the claim.
A5.8 Thermal-performance statement
“The blanket material has been tested under defined direct-flame and thermal-loading conditions.”
Product pages should state the actual classification, temperature, exposure time, test method and report reference where these details are used commercially.
A quoted “working temperature” or “maximum temperature” should not be presented without explaining whether it refers to the base fabric, coated material, short-duration exposure, continuous exposure or complete product.
A5.9 Reaction-to-fire statement
“Reaction-to-fire classification: [state the exact classification and test-report reference].”
The classification should be copied accurately from the applicable report and should not be upgraded, simplified or expanded beyond the report scope.
A5.10 Mechanical-performance statement
“Material, seams and lifting or pull loops have been evaluated under the applicable mechanical test programme.”
A fabric tensile-strength result should not be presented as proof of complete blanket, seam or loop strength.
A5.11 Radio-frequency statement
“The manufacturer states that the blanket is radio-frequency permeable under the identified conditions.”
The basis, scope and limitations of the statement should be available.
A5.12 PFAS and material statement
“Material and coating declarations, including PFAS information where applicable, are available on request.”
The wording should correspond exactly with the declaration supplied.
A5.13 Inspection statement
“Periodic visual inspection is required. DVM recommends a documented inspection at least once every year when the blanket is not in use.”
More frequent inspection may be appropriate in outdoor, mobile, industrial, humid, contaminated or training environments.
A5.14 Reuse statement
“Reuse is permitted only after post-use quarantine, inspection and documented acceptance in accordance with the manufacturer’s instructions.”
The product should not be described simply as “reusable” without stating the inspection, contamination, damage and acceptance conditions.
A5.15 Single-use statement
“Single-use Fire Limitation Blanket. Replace after deployment.”
A5.16 OEM and private-label statement
“Available for OEM or private-label supply using the approved product construction, dimensions, packaging, instructions and traceability system.”
OEM availability should not imply that any requested change can be made without reviewing the applicability of existing evidence.
A6. Claims That Require Particular Caution
A6.1 “Extinguishes EV battery fires”
This wording should not be used for a Fire Limitation Blanket unless a narrowly defined claim is supported by applicable evidence and does not conflict with the documented function of the product.
Preferred wording focuses on limiting heat, flames, smoke and fire spread.
A6.2 “Stops thermal runaway”
This claim should not be used unless the product has been demonstrated to achieve that result under clearly defined and representative conditions.
Covering a vehicle does not remove the stored energy in the traction battery and does not automatically stop continuing cell reactions, gas generation or reignition.
A6.3 “Fire suppression blanket”
This term may be encountered in searches and historical documents, but it can imply a stronger extinguishing or suppression function than the evidence supports.
DVM therefore prefers Fire Limitation Blanket.
A6.4 “Battery fire blanket”
This search term may suggest direct use on a battery. Product pages should make clear that Fire Limitation Blankets under DIN SPEC 91489 are intended for use on electric vehicles and not for direct use on a removed and opened traction battery.
A6.5 “Reusable”
The term should only be used with clear post-use conditions, including quarantine, contamination assessment, damage inspection and documented approval for further service.
A6.6 “Maintenance-free”
This wording should not be used where periodic inspection, storage control or post-use assessment is required.
A6.7 “Certified”
Certification wording should only be used where an actual certificate has been issued under a defined certification process or scheme.
Independent testing alone does not justify a certification claim.
A7. Prohibited or Misleading Statements
The following statements should not be used unless their exact meaning, scope and evidence make them demonstrably accurate:
- “DIN approved”;
- “DIN certified” where no applicable certificate exists;
- “certified to DIN SPEC 91489” based only on a test report;
- “complies with DIN SPEC 91489” based only on material testing;
- “extinguishes EV battery fires”;
- “stops thermal runaway”;
- “prevents reignition” as an absolute claim;
- “safe for all electric vehicle fires”;
- “works on every vehicle”;
- “suitable for direct use on open traction batteries”;
- “fireproof” where unlimited resistance may be implied;
- “reusable after every incident”;
- “maintenance-free”;
- “safe on electricity” or equivalent electrical-PPE wording;
- “non-toxic” without a precise and supportable scope;
- “zero smoke” or “zero emissions”;
- “contains all hazardous gases”;
- “guarantees protection of adjacent vehicles”;
- claims extending results to unsupported sizes or models;
- claims using a draft standard as though it were a final standard;
- language claims that do not match the supplied product;
- claims that ignore post-use contamination and disposal risks.
A test report records testing performed against identified requirements. A conformity statement asserts that the identified product meets the applicable requirements. A certificate is issued under a defined certification process or scheme.
Product-page wording should not convert a material report or independent test report into a complete-product conformity or certification claim unless the necessary evidence and formal basis exist.
A8. Material Testing Versus Complete-Product Testing
Product pages should distinguish clearly between:
- base-fabric testing;
- coating or composite-material testing;
- reaction-to-fire classification;
- thermal-load testing;
- mechanical testing of material samples;
- seam and loop testing;
- application testing of the complete product;
- complete-product assessment against DIN SPEC 91489.
| Evidence type | What it can support | What it does not prove by itself |
|---|---|---|
| Fabric or coating report | Characteristics of the identified material or coating. | Complete blanket performance, deployment, seam strength, loop strength or conformity. |
| Reaction-to-fire report | The exact classification recorded for the tested material construction. | Application performance or complete-product conformity. |
| Thermal test report | Performance under the stated exposure conditions. | Unlimited temperature resistance or performance under every vehicle-fire condition. |
| Mechanical material test | Tensile, cut or other properties of the tested sample. | Strength of complete seams, edges, loops or the assembled blanket. |
| Application video | Deployment of the shown model under the recorded conditions. | Thermal, chemical, mechanical or complete conformity by itself. |
| Complete-product test report | Requirements and results within the identified scope. | Automatic transfer to different sizes, materials, packaging or private-label versions. |
| Product certificate | Certification within the identified scheme, scope and conditions. | Claims outside the certificate scope. |
A9. Technical Data and Product Specifications
A professional product page should identify the product sufficiently clearly for buyers to match it with available technical, test and supply documentation.
Relevant information includes:
- official product name;
- model and article number;
- finished dimensions;
- product weight;
- base fabric and material construction;
- coating type and coated sides;
- thickness and relevant material weights;
- seam, edge and reinforcement construction;
- number and position of loops;
- storage-container and folding configuration;
- intended vehicle categories;
- required number of instructed persons;
- applicable technical-rule reference and edition;
- reaction-to-fire classification;
- verified thermal and mechanical statements;
- radio-frequency information;
- inspection and replacement guidance;
- reuse or single-use status;
- available test and technical documents;
- traceability method;
- available language versions;
- warranty conditions where applicable.
A10. Application and Deployment Claims
Any deployment claim should correspond with the exact tested model and supplied configuration.
Product pages should identify:
- the required number of instructed persons;
- the starting condition of the product;
- the vehicle type or reference dimensions;
- the application time where claimed;
- whether dry and wet application were evaluated;
- the final coverage achieved;
- the storage container and folding method;
- the applicable video or test-report reference;
- operational limitations and required PPE.
A staged marketing video should not be described as a formal application test unless it follows the applicable procedure and records the required conditions.
A11. Temperature and Fire-Performance Claims
Temperature claims require particular care because several different values may be used for the same product.
Product pages should distinguish between:
- continuous operating temperature;
- short-duration exposure temperature;
- melting or softening temperature of a material;
- flame temperature used in a test;
- temperature measured on the exposed surface;
- temperature measured on the protected side;
- reaction-to-fire classification;
- temperature limits for the complete product.
A melting point is not the same as a safe working temperature. A short-term exposure value is not the same as a continuous-use limit.
“Material temperature data are stated according to the applicable test or supplier documentation. They should not be interpreted as a guarantee of complete-product performance under every vehicle-fire condition.”
A12. Reuse, Quarantine and Disposal Claims
Product pages should state clearly whether the blanket is:
- single use;
- potentially reusable under defined conditions; or
- subject to manufacturer assessment after deployment.
Where reuse is possible, the page should explain that the product must first be quarantined and assessed for:
- thermal degradation;
- cuts, tears or seam damage;
- loop damage;
- chemical or hazardous contamination;
- battery gases, smoke or fire residues;
- loss of markings or traceability;
- deformation affecting future deployment;
- unknown use or handling history.
Disposal claims should be consistent with applicable hazardous-material and waste procedures.
A13. OEM and Private-Label Product Pages
OEM and private-label product pages require particular attention because the branding, dimensions, packaging, instructions or product construction may differ from the originally tested configuration.
Before publication, verify:
- that the product construction remains within the evidence scope;
- that dimensions and weight remain documented;
- that materials and coatings remain unchanged;
- that seams, edges, reinforcements and loops remain equivalent;
- that packaging and folding match the validated deployment configuration;
- that the private-label model can be linked to the applicable evidence;
- that required manufacturer, importer and brand-owner information is correct;
- that all required market-language versions are present;
- that artwork and instructions are approved before production;
- that batch and production traceability remain available;
- that changes are controlled and documented;
- that continued evidence applicability is reviewed after changes.
A change of branding alone may not affect performance. Changes to materials, coatings, dimensions, seams, loops, folding, packaging or instructions may affect whether existing evidence remains applicable.
A14. International Product Pages
Product pages intended for more than one country should distinguish between:
- the technical rule used as a product reference;
- the edition used for testing or procurement;
- the countries in which the product is offered;
- the languages supplied;
- the responsible parties in the supply chain;
- country-specific legal or marking requirements;
- available test, chemical and waste documentation;
- training and instructed-person requirements.
DIN SPEC 91489 may be used as a technical reference in international procurement. This does not automatically establish compliance with every legal or market-access requirement in every country.
A15. SEO and Search-Language Guidance
Professional product pages should use search terminology naturally and accurately.
Recommended approach:
- use Fire Limitation Blanket as the official product term;
- include EV fire blanket and electric vehicle fire blanket in natural explanatory text;
- use vehicle fire blanket or car fire blanket where relevant to the audience;
- use battery fire blanket only with a clear scope explanation;
- avoid repeating alternative terms unnaturally;
- connect each search term to the documented product function;
- avoid implying active extinguishment for SEO purposes;
- use DIN SPEC 91489 only where the claim is accurate and supportable.
“This professional Fire Limitation Blanket is commonly searched for as an EV fire blanket or electric vehicle fire blanket. It is designed to help limit heat, flames, smoke and fire spread around an electric vehicle.”
“Best EV battery fire suppression blanket that extinguishes all electric car fires and stops thermal runaway.”
A16. Recommended Product-Page Structure

A17. Standard Product-Page Reference Block
The following block may be adapted for professional product pages, provided that every statement is accurate and supported for the product being offered.
DVM Fire Limitation Blanket Reference
This product is documented and presented within the DVM Fire Limitation Blanket Reference, a professional technical and procurement framework informed by DIN SPEC 91489.
A Fire Limitation Blanket, commonly searched for as an EV fire blanket or electric vehicle fire blanket, is intended to help limit the development and spread of heat, flames, smoke and burning particles around an electric vehicle.
It is not an active extinguishing agent and should not be represented as a guaranteed method for stopping thermal runaway or extinguishing every traction-battery fire.
Product claims apply only where the relevant requirement is satisfied and supported by evidence for the exact product configuration being supplied.
The DVM Fire Limitation Blanket Reference is not a DIN, EN, CEN, ISO or government-issued standard, does not create separate certification and does not replace the applicable technical rule, product-specific test reports, risk assessments or manufacturer instructions.
A18. Product-Page Review Record
Before a professional product page is approved or published, the review record should identify:
- product name, model and article number;
- dimensions and weight;
- materials and coatings;
- seam, edge and loop configuration;
- storage-container and folding configuration;
- brand or private-label version;
- intended countries or markets;
- supplied language versions;
- technical-rule edition;
- reviewed claims;
- supporting evidence for each material claim;
- document titles, versions and dates;
- reviewer name or role;
- approval date;
- identified limitations or approval conditions;
- date or trigger for future review.
The page should be reviewed again when there is a relevant change to:
- the product specification;
- materials or coatings;
- dimensions or weight;
- seams, edges, reinforcements or loops;
- folding or packaging;
- artwork or supplied languages;
- manufacturer or responsible supplier;
