Abrasion Resistance
Based on the number of cycles required to abrade through the glove.
(Highest performance level 4 = 8,000 cycles)

Puncture Resistance
Based on the amount of force required to pierce the glove with a standard-sized point.
(Highest performance level 4 = 150 Newtons)

Blade Cut Resistance
Based on the number of cycles required to cut
through the glove with a circular blade at a constant
speed.
(Highest performance level 5 = index 20)

EN ISO 13997 Cut Resistance
Based on the minimum force required to cut through the glove with a straight blade.
(Highest performance level F = 30 Newtons)

Tear Resistance
Based on the amount of force required to tear
the glove.

Protection From Ignition

Based on the length of time the material continues to burn and

glow after the source of ignition is removed. The seams of the

glove shall not come apart after an ignition time of 15 seconds.

(Highest performance level 4 = after-flame time 2 seconds, afterglow

time 5 seconds)

Protection From Radiant Heat

Based on the length of time the glove is able to delay the

transfer of heat when exposed to a radiant heat source.

(Highest performance level 4 = at least 150 seconds)

Protection From Contact Heat

Based on the temperature range (100-500 °C) at which the user will

feel no pain for at least 15 seconds.

(Highest performance level 4 = + 500 °C)

Protection From Droplets of Molten Metal

The number of molten metal drops required to heat the

glove to a given level.

(Highest performance level 4 = over 35 droplets)

Protection From Convective Heat (gradually penetrating heat)

Based on the length of time the glove is able to delay the transfer

of heat from a flame from an open fire.

(Highest performance level 4)

Protection From Molten Metal

The weight of molten metal required to cause damage (smoothing or pin-holing) across a simulated skin (attached to the inside of the glove).

(Highest performance level 4 = 200 grams)
