Are there any other widely used standards for flammability testing of textiles?

There are several other widely used standards for flammability testing of textiles. Here are a few additional examples:

1. ISO 6940: Textiles - Burning behaviour - Vertical method: This standard is similar to ASTM D6413 in that it measures the flame spread of a vertically oriented textile specimen when exposed to a small flame. The test method involves exposing the specimen to a small flame for a specified period of time and measuring the duration of flame spread.

2. ISO 6941: Textiles - Burning behaviour - Horizontal method: This standard is similar to ISO 6940, but measures the flame spread of a horizontally oriented textile specimen under the same conditions.

3. BS 5852: Methods of test for assessment of the ignitability of upholstered seating by smouldering and flaming ignition sources: This British standard is used to evaluate the ignitability of upholstered seating materials when exposed to smouldering and flaming ignition sources. The test methods involve exposing the specimen to a lit cigarette or a gas flame, and measuring the duration and extent of flame spread.

4. California Technical Bulletin 117 (TB 117): Requirements, Test Procedure and Apparatus for Testing the Flame Retardance of Resilient Filling Materials Used in Upholstered Furniture: This standard is used to evaluate the flame resistance of foam materials used in upholstered furniture. The test method involves exposing the foam specimen to an open flame for a specified period of time, and measuring the amount of heat released and the duration of flame spread.

These are just a few examples of the many standards available for flammability testing of textiles. It's important to select the appropriate test method based on the intended use of the textile product, and to follow the testing procedures and requirements outlined in the standard in order to ensure accurate and reliable test results.
