1.7s AFTERFLAME TIME

Forged with flame and cut-resistant materials, SHOWA 240 is the ultimate armor for arc flash protection in high-risk industries. Featuring a 13-gauge seamless knit liner reinforced with Kevlar® and sponge neoprene palm coating inherently flame-resistant.

ASTM D6413 STANDARD TEST METHOD FOR FLAME RESISTANCE OF TEXTILES (VERTICAL TEST)

Afterflame time:

number of seconds during

which there is a visible flame

remaining on the fabric.

Afterglow time:

the number of seconds during

which there is a visible glow

remaining on the fabric.

Char length:

the length in inches of fabric

destroyed by the flame. Pass if

less than 6 inches.

Melt/drip:

recorded occurrence of

melting or dripping, if any.

ASTM F2675 TEST METHOD FOR RESISTANCE OF TEXTILES FROM ELECTRIC ARC FLASH

Arc thermal protective value (ATPV): the amount of heat (cal./

cm2) that is sufficient to cause second-degree burn injury, based

on the Stoll Curve at 50% probability.

Arc rating: Level 1 > 4 cal./cm2, level 2 > 8.0 cal./cm2,

level 3 > 24.9 cal./cm2, level 4 > 40 cal./cm2
