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

Stand van zaken met betrekking tot het raamwerk en de normen

This checklist is part of a technical reference and procurement framework developed by DVM International B.V.

Het betreft geen DIN-, EN-, CEN-, ISO- of door de overheid vastgestelde norm. Deze norm leidt niet tot een afzonderlijke productcertificering, vormt geen wettelijke conformiteitsbeoordelingsprocedure en vervangt evenmin DIN SPEC 91489:2024-11, de toepasselijke wetgeving, productspecifieke testrapporten, risicobeoordelingen of de instructies van de fabrikant.

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.

Belangrijke functionele beperking

Een brandbeperkingsdeken is geen actief blusmiddel en mag niet worden beschreven als een middel om een brand in een tractieaccu te blussen of om thermische runaway te stoppen.

Deze productcategorie is bedoeld voor gebruik in elektrische voertuigen en niet voor direct gebruik op een verwijderde en geopende tractiebatterij.

Hoe gebruik je deze 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?

Paragraaf 3 – Afmetingen, gewicht en dekking van het voertuig

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?

Hoofdstuk 4 – Materialen, coatings en constructie

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.

Richtlijnen voor het toekennen van punten

De onderstaande scoreklassen vormen een interne interpretatie in het kader van de aanbesteding. Ze vormen geen wettelijke conformiteitsbeoordeling of productcertificering.

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.

Essentiële vereisten

De volgende tekortkomingen zouden normaal gesproken een onvoorwaardelijke goedkeuring in de weg moeten staan, ongeacht de behaalde 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;
De beweringen van de leverancier gaan verder dan wat uit het beschikbare bewijsmateriaal blijkt.

Aanbevelingen inzake bewijsvoering

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;
technische gegevensbladen en producttekeningen;
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;
dat de traceerbaarheid per model en per partij ook bij de huismerk- uitvoering gewaarborgd blijft;
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.

Further evidence required: the assessment cannot be completed because relevant test, application, technical or traceability information is missing.
Afgewezen: een of meer veiligheidskritische eisen zijn niet vervuld, of de opgegeven productclaims kunnen niet voldoende worden onderbouwd.

Wanneer moet de nalevingsmatrix worden gebruikt?

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;
per vereiste moeten afzonderlijke bewijsstukken worden vastgelegd;
Bij beslissingen ‘Geslaagd’, ‘Niet geslaagd’ en ‘N.v.t.’ moeten opmerkingen worden toegevoegd of corrigerende maatregelen worden genomen;
een OEM- of private-label-configuratie vereist een grondige beoordeling;
the assessment forms part of a formal quality or procurement file;
test-result transfer or product equivalence must be evaluated.
