What are the standards for flame retardant testing and how to choose?

The standards for flame retardant test vary depending on the application area and country/region. The following are some commonly used flame retardant test standards, you can choose the suitable standard according to the specific situation:

1. American Standard:

   - ASTM D6413: Vertical flammability test standard for textile materials, commonly used in industries such as flame retardant workwear.

   - NFPA 701: for curtains and textiles and other movable interior fabric flame retardant performance requirements. 2.

2. European Standard:

   - EN ISO 15025: Based on vertical burning tests for assessing the flame retardancy of textiles and other materials.

   - EN 13501: Covers flame propagation properties of building materials, including floors, walls, ceilings, etc.

3. International Standards:

   - ISO 6940 and ISO 6941: apply to vertical and horizontal combustion testing of textile materials respectively.

   - ISO 9151: Radiant heating test method for evaluating flame retardant properties, applicable to rescue equipment, insulated clothing, etc.

The following factors can be considered when choosing a suitable flame retardant test standard:

1. Field of application:

Different industries and products may have specific flame retardant requirements. Determine the required flame retardant performance level and test method, and then look for a suitable standard for that application area.

2. National/regional requirements:

Understand the regulatory and standards requirements of the target sales market or region of use. These requirements may specify specific flame retardant test standards that you need to comply with.

3. quality certification:

If your product needs to pass a specific certification or marking, such as the European Union CE marking, U.S. NFPA certification, etc., it is recommended to check the requirements of the certification body and comply with its flame retardant test standards.

4. Industry recommendation:

Industry organizations, professional bodies or experts in related fields often have recommendations and guidelines on flame retardant test, which can be referred to.

When selecting a standard, attention should also be paid to the latest version of the standard and any revisions. In addition, to ensure accuracy and consistency, it is recommended that the flame retardant test be carried out in an accredited laboratory or a specialized agency to obtain authoritative test results and certificates.
