ASTM is a vertical flame test method that determines a textile’s response to a standard ignition source. ASTM D-6413 must be used to comply with OSHA 1910.269, and derives measurement values for after flame time, afterglow time, and char length.
Limited Flammability (LF) is used by MCR Safety to highlight garments that will self-extinguish within a matter of seconds, once the source of the flame is removed. We use this test method for determining if a product is LF-compliant. Garments with LF capability are not for flash fires or arc flash protection.
