Our EV Car Fire Blanket Is Tested to DIN SPEC 91489: What It Means and Why It Matters

Product news · Testing

Our 8m x 6m EV car fire blanket has been tested by SGS to DIN SPEC 91489:2024-11, the first published specification written specifically for fire blankets used on electric vehicles. Here's what that specification checks, why it matters when there's no Australian equivalent, and what it does and doesn't mean.

Why a specification for EV fire blankets was needed

Until recently, anyone buying a vehicle fire blanket had very little to compare. Sellers quoted temperature ratings, fabric weights or general reaction-to-fire classifications, but nothing tested whether a blanket would actually hold up over a burning car, survive being hit with water or foam, or could be pulled into place quickly by the people who'd be using it.

That gap matters more every year. Fire and Rescue NSW attended 332 lithium-ion battery incidents in 2025, up from 165 in 2022 (NSW Government, 2026), and more strata buildings, workshops, fleets and car parks are now looking for equipment they can actually justify.

In November 2024, the German Institute for Standardization (DIN) published DIN SPEC 91489:2024-11, Requirements for fire limitation blankets for use with electric vehicles (DIN, 2024). It was developed through DIN's PAS process by a consortium of contributors, and it's free to download from DIN. There's still no Australian Standard for lithium-ion battery fire blankets, so this is currently the most specific benchmark available anywhere.

What DIN SPEC 91489 actually tests

The specification goes well beyond "can the fabric take heat". It sets requirements for the whole product, including how it's handled and stored. The main ones are:

Our result

SGS tested our 8m x 6m silicone-coated fibreglass blanket against the specification between January and June 2026. It met the applicable requirements, including the direct-flame and extinguishing-agent heat tests, a B-s1, d0 reaction-to-fire classification, level A cut resistance, strap strength, two-person deployment over a vehicle, and PFAS-free materials.

You can download our one-page test summary (PDF), and the full SGS report is available on request for buyers who need it for procurement, insurance or WHS records.

Our 5m x 5m and 2m x 2m blankets are made from the same tested fabric. Because DIN SPEC 91489 is written for blankets that cover a whole vehicle, we only describe the 8m x 6m as tested to it.

What it doesn't mean

We'd rather be clear about the limits than oversell a test result:

• A fire blanket contains; it doesn't extinguish. DIN SPEC 91489 itself says fire limitation blankets are not active extinguishing agents. The blanket limits flames and spread and buys time. It won't stop a battery in thermal runaway.
• It isn't for a removed, opened battery. The specification covers use over a vehicle, not direct use on a traction battery that has been taken out and opened.
• It doesn't protect against electric shock. Keep clear of a damaged EV's high-voltage system and leave that to Fire and Rescue.
• It isn't an Australian certification. It's a German specification, tested by an independent laboratory. It supplements the fire safety measures your building is required to have; it doesn't replace them.

Why it matters if you're buying

For strata committees, fleet managers, councils and workshops, a published specification gives you something concrete to ask for. Rather than comparing temperature claims, you can ask a supplier three simple questions:

• Has this exact blanket been tested to DIN SPEC 91489:2024-11?
• Which laboratory tested it, and what's the report number?
• Will you supply the test report?

If the answers are vague, that tells you something too.
