BS 5438:1989纺织品可燃性测试

BS 5438:1989: Methods of test for flammability of textile fabrics when subjected to a small igniting flame applied to the face or bottom edge of vertically oriented specimens. 样品垂直放置时，表面或底部边沿以小火焰燃烧，纺织品可燃性测试。

BS 5438:1989 Test 2A: face ignition (表面燃烧)

BS 5438:1989 Test 2B: Bottom edge ignition （底部边沿燃烧）

BS 5438:1989 apply the igniting flame for 10s or the flame application time given in the performance specification.

Note: BS 6853:1999 flame time application is 15s.

纺织品的可燃性测试通过如下方面来评估:

1. 火焰持续时间 2. 后燃烧持续时间 3. 样品破坏范围 、、、、、、
