Fire Limitation Blanket Procurement Audit Checklist for EV Fire Blankets

The DVM Fire Limitation Blanket Procurement Audit Checklist is a practical, buyer-ready verification tool for products commonly described as Fire Limitation Blankets, EV fire blankets, electric vehicle fire blankets, vehicle fire blankets or car fire blankets.

The checklist is informed by DIN SPEC 91489:2024-11 and supports supplier qualification, tender preparation, technical-offer review, OEM and private-label projects, procurement approval and document retention.

DVM Fire Limitation Blanket Procurement Audit Checklist

This checklist converts the principal technical, documentary, deployment, marking, inspection and traceability considerations for Fire Limitation Blankets into twenty-five objective Yes/No verification points.

It is intended for professional buyers, distributors, OEM customers, private-label partners, quality managers, product managers, fire-safety organisations and other technical decision-makers evaluating EV fire blankets and their suppliers.

The technically preferred term throughout this Reference is Fire Limitation Blanket. Common search terms such as EV fire blanket, electric vehicle fire blanket, car fire blanket, vehicle fire blanket, battery fire blanket and fire containment blanket are used where they help buyers identify the product category.

DVM Fire Limitation Blanket Procurement Audit Checklist
Technical basis: Informed by DIN SPEC 91489:2024-11
Purpose: Supplier qualification, tender support, technical-offer evaluation, OEM and private-label procurement, and documented purchasing decisions

Framework and standards status

This checklist 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 this checklist is used for procurement, testing or product claims.

Important functional limitation

A Fire Limitation Blanket is not an active extinguishing agent and should not be described as extinguishing a traction-battery fire or stopping thermal runaway.

The product category is intended for use on electric vehicles and not for direct use on a removed and opened traction battery.

How to use this checklist

Record “Yes” only when the requirement is applicable and supported by objective, relevant and traceable evidence for the exact product model, size, weight, construction, loop arrangement, packaging and instruction set being offered.

Record “No” where the requirement is not met or where suitable evidence is unavailable. Do not convert an unanswered question, general brochure claim, fabric certificate or unsupported supplier statement into a positive result.

Where a point is genuinely not applicable, record “N/A” separately and explain why. Do not use N/A to avoid a mandatory or safety-critical requirement.

For every “Yes”, archive the relevant evidence in the procurement or quality file. This may include a complete-product test report, material report, technical data sheet, application video, approved drawing, packaging artwork, declaration, traceability record or inspection document.

Search terminology and technical accuracy

Buyers may begin their research with terms such as EV fire blanket, electric vehicle fire blanket, car fire blanket, vehicle fire blanket, battery fire blanket or fire containment blanket. The checklist verifies whether those commercial terms are linked to the technically accurate function of a Fire Limitation Blanket.

Section 1 – Product and Supplier Identification

Are the manufacturer and responsible supplier clearly identified with the required name and address information?
Is a unique product name, model designation and article number stated consistently on the product, packaging, technical documentation and test reports?
Are the finished dimensions, product weight and batch or serial identification stated and traceable to the supplied product?

Section 2 – Intended Function and Product Claims

Is the product described primarily as a Fire Limitation Blanket, or with equivalent wording that does not imply active extinguishment?
Where alternative terms such as EV fire blanket, electric vehicle fire blanket, car fire blanket, vehicle fire blanket or battery fire blanket are used, are they explained in technically accurate context?
Is the intended function limited to helping contain heat, flames, smoke and burning particles and reducing fire spread to the surrounding area?
Are unsupported claims absent, including claims that the product extinguishes a traction-battery fire, stops thermal runaway, guarantees prevention of reignition or is suitable for every EV fire scenario?

Section 3 – Dimensions, Weight and Vehicle Coverage

Are the finished blanket dimensions stated in metres and supported by product specifications, measurements or test documentation?
Is the declared weight supported and consistent with the exact product configuration being supplied?
Do the selected dimensions provide suitable coverage for the intended vehicle category, including sufficient material to reach the ground around the vehicle during the application demonstration?

Section 4 – Materials, Coatings and Construction

Are the base fabric, coating type, coated sides, total construction, thickness and relevant material weights identified clearly?
Are seams, overlaps, edge finishing, reinforcements, pull or lifting loops and their attachment methods documented and consistent with the tested configuration?
Are relevant material, PFAS, chemical or environmental declarations available where required or requested?

Section 5 – Mechanical and Thermal Evidence

Is applicable evidence available for mechanical stability, including seam, edge, loop and material strength, and cut resistance where required?
Is applicable evidence available for flexibility and deformation resistance of the finished coated material construction?
Is reaction-to-fire classification supported for the applicable material construction, including at least class B with d0 under DIN EN 13501-1 where DIN SPEC 91489:2024-11 is the basis?
Are direct-flame and thermal-performance claims supported by defined test conditions, temperature data and documented observations or failure criteria?

Section 6 – EV Fire Blanket Deployment

Is application evidence available for the exact model, beginning with the blanket in its supplied storage container or packaging?
Where DIN SPEC 91489:2024-11 is the basis, has deployment by no more than two instructed persons within the applicable 30-second criterion been demonstrated?
Has the product been demonstrated on the applicable reference vehicle and under both dry and wet vehicle conditions where required?
Does video evidence show the starting configuration, personnel, timing, vehicle condition, deployment process and final vehicle coverage clearly?

Section 7 – Marking, Instructions and Languages

Do the product and storage packaging provide clear identification, dimensions, model, traceability, orientation and applicable technical-rule information?
Do the instructions address intended use, limitations, required personnel, deployment, storage, periodic inspection, radio-frequency information, reuse, quarantine, replacement and disposal?
Are all required instructions, warnings, pictograms and labels supplied in the language or languages required for the intended market?

Section 8 – Test Documentation, OEM and Final Approval

Can all test reports, application videos, declarations and technical documents be traced to the exact product, construction, model, packaging and production version being purchased?

Supplementary Procurement Checks

In addition to the twenty-five principal verification points, the buyer should review the following supporting matters where applicable.

whether the blanket is stated to be radio-frequency permeable and what evidence supports that statement;
whether electrical and electrostatic limitations are communicated clearly;
whether water, vehicle-fluid, chemical, abrasion, transport and storage exposure are addressed;
whether the manufacturer defines periodic inspection and recommends a documented interval;
whether post-use quarantine, assessment, reuse and disposal conditions are clear;
whether test-result transfer between sizes or models is technically justified;
whether the applicable DIN SPEC or draft-standard edition is identified accurately;
whether the intended countries, required languages and responsible economic operators have been defined;
whether national fire-safety, occupational-safety, chemical and waste requirements have been reviewed;
whether the term “certified” is used only where an actual certification scheme and certificate apply.

Scoring Guidance

The following scoring bands are an internal procurement interpretation. They do not constitute legal conformity assessment or product certification.

25/25 – Complete documented alignment: all verification points are answered “Yes” and supported by suitable, relevant and traceable evidence.
22–24 – Limited documentary or formal gaps: corrective action or additional evidence is required before final procurement approval.
21 or fewer – Material procurement gaps: the product should not be treated as fully documented or equivalent without further investigation, testing, evidence and corrective action.

A high numerical score does not override a safety-critical failure. Missing application evidence, unsupported thermal or mechanical claims, unsuitable dimensions, unclear instructions, inconsistent product configurations or loss of traceability may justify rejection regardless of the total score.

Critical Requirements

The following deficiencies should normally prevent unconditional approval, regardless of the numerical score:

the offered product cannot be matched to the available complete-product test or technical documentation;
application evidence is missing for the exact model or configuration;
thermal or mechanical performance claims are unsupported;
materials, coatings, seams, loops or dimensions differ materially from the documented configuration;
deployment instructions are absent, unclear or inconsistent with the application evidence;
required language versions are missing;
product or batch traceability is absent;
the product is marketed as an active extinguishing agent or as a guaranteed method for stopping thermal runaway;
reuse is claimed without documented post-use inspection and acceptance criteria;
supplier claims extend beyond the scope of the available evidence.

Evidence Recommendations

For every positive result, the buyer should retain evidence appropriate to the requirement. Depending on the verification point, this may include:

the applicable complete-product test report;
reaction-to-fire and thermal-test reports;
mechanical, cut-resistance and loop-strength reports;
application-test video for the exact model;
technical data sheets and product drawings;
material, coating, PFAS and chemical declarations;
approved packaging and folding documentation;
approved artwork, labels, instructions and language versions;
batch-controlled production and inspection records;
manufacturer declarations identifying the exact product;
inspection, quarantine, reuse, replacement and disposal instructions;
change-control records for OEM and private-label versions.

A fabric or coating report may support material characteristics, but it should not be treated as proof that the complete EV fire blanket meets all relevant requirements for dimensions, seams, loops, deployment, marking, instructions and traceability.

Additional OEM and Private-Label Checks

For OEM and private-label procurement, confirm:

that the private-label product uses the approved materials, coatings, dimensions, weight and construction;
that seam, edge, reinforcement and loop drawings are approved before production;
that the storage container, folding method and packaging match the validated application configuration;
that artwork and all required market-language versions are approved;
that manufacturer, brand-owner, importer and distributor responsibilities are defined;
that model and batch traceability remain available under the private-label presentation;
that the private-label model can be linked to the applicable test evidence;
that material, construction, packaging and artwork changes are controlled;
that the continued applicability of test evidence is reviewed after each relevant change.

Procurement Decision Record

The completed checklist should identify:

supplier and manufacturer;
product name, model and article number;
finished dimensions and product weight;
material and coating construction;
seam, edge and loop configuration;
storage-container and folding configuration;
brand or private-label version;
intended countries or markets;
required language versions;
technical-rule edition used;
assessment date;
evaluator name or role;
evidence reviewed for every answer;
document titles, versions and dates;
identified gaps and corrective actions;
final procurement decision;
approval conditions;
date or trigger for reassessment.

Recommended Decision Categories

Approved: all applicable safety-critical requirements have been satisfied and sufficient evidence is available.
Conditionally approved: limited non-safety-critical gaps remain and are subject to documented corrective action before production or supply.
Further evidence required: the assessment cannot be completed because relevant test, application, technical or traceability information is missing.
Rejected: one or more safety-critical requirements have failed, or the stated product claims cannot be supported adequately.

When to Use the Compliance Matrix

This Procurement Audit Checklist provides a concise twenty-five-point Yes/No assessment. Use the more detailed Fire Limitation Blanket Compliance Matrix when:

multiple products or suppliers must be compared in detail;
individual evidence items must be recorded per requirement;
Pass, Fail and N/A decisions require comments or corrective actions;
an OEM or private-label configuration requires detailed review;
the assessment forms part of a formal quality or procurement file;
test-result transfer or product equivalence must be evaluated.
