How to Determine if Tarpaulin Has Fire-Retardant or Flame-Retardant Properties?

Fire-Retardant/Flame-Retardant Determination – Key to Safe Material Selection

1. Check Product Certificates and Labels

Qualified fire-resistant tarpaulin will indicate its flame-retardant rating (e.g., B1, B2, M1, M2) and the international/domestic standards it complies with (e.g., NFPA701, DIN75200) on the product description or label. When purchasing, you can request the supplier to provide the corresponding fire-resistant test report or SGS/RoHS certificates.

2. Understand the Meaning of Flame-Retardant Ratings

B1, B2: Domestic flame-retardant ratings for building materials. B1 is the highest level, indicating that the material is unlikely to produce flames when burning and can self-extinguish.

M1 and M2: European flame retardant standards. M1 is also a high flame retardant rating, suitable for outdoor tents, awnings, etc.

NFPA 701: American Fire Protection Association standard, testing the flammability of textiles.

3. On-site Burning Test

For special projects (such as large exhibitions, industrial sites), a third-party testing agency can be commissioned to conduct on-site burning tests to verify the material's flame retardant performance under actual use conditions. The test report will list key indicators such as burning time, smoke density, and heat release rate.

4. Technical Considerations When Purchasing

Confirm that flame retardants (such as phosphorus-based or nitrogen-based flame retardants) have been added to the material formulation and meet the corresponding testing requirements.

Check for fire retardant certification marks (B1, M1, etc.) and verify the certificate number and the validity period of the testing agency.

For applications requiring higher fire retardant ratings, "fire-retardant PVC tarpaulin" can be selected, which will clearly indicate in the product description that it has passed B1, M1, and other level tests.
