Description

Product Introduction:

This standard specifies a method for determining the vertical flame‑spread performance of textiles used in single‑component or multi‑component garments, curtains, draperies, and large‑scale tents—including canopies and door curtains—under laboratory‑controlled conditions. It is also applicable to the assessment of the vertical burning characteristics of automotive interior curtains, sunshades, and other interior hanging materials, enabling the determination of the burn distance and burn time when such materials or material assemblies are exposed to a flame under controlled laboratory conditions.

Reference standard:

GB/T 5456, GB 32086, ISO 15025, ISO 6940, ISO 6941, and others.
