Welder Gloves Heat Resistant

It is designed to be used in welding works. It has high fire resistance. There is no reinforcement on the palm or fingers. All seams are made of fireproof aramid thread, which increases durability.  Palm Material Split leather Lining Material Coton Size / Length 35cm Carton / Package Quantity 72 / 1 Pair Category CAT II StandardEN 388:2016+A1:2018 (312) 2X) EN 407:2004 (41314X) EN 420:2003+A1:2009 a.  Ignition resistance  (performance level 0 – 4) b.  Contact heat resistance  (performance level 0 – 4) c .  Convective heat resistance  (performance level 0 – 4) d.  Radiant heat resistance  (performance level 0 – 4) e.  Resistance to small splashes from molten metal  ; (performance level 0 – 4) f.  Resistance to large splashes from molten metal  (performance level 0 – 4) a) Resistance to ignition The length of time the material continues to burn and heat up after the source of ignition has been removed It endures. After a 15-second ignition period, the stitches of the glove should not break. b) Contact heat resistance Resists the temperature range (100-500 °C) where the user does not feel pain for at least 15 seconds. If an EN level 3 or higher is provided, it should be noted that the product was at least EN level 3 in the ignition test. Otherwise, the maximum Contact temperature level should be reported as level 2. c) Convective heat resistance is based on the length of time the glove can delay heat transfer from the flame. When level 3 or 4 performance in the ignition test is achieved, the performance level should be stated. d) Radiant heat resistance is based on the length of time the glove can delay heat transfer when exposed to a radiant heat source. When level 3 or 4 performance in the ignition test is achieved, the performance level should be stated. e) Resistance to small splashes from molten metal: The number of drops of molten metal required to heat the glove to a given level. When level 3 or 4 performance in the ignition test is achieved, the performance level should be stated. f) Resistance to large splashes from molten metal: The weight of molten metal required to form smoothing or pinpoint-sized holes through an artificial skin placed directly under the glove. If metal droplets adhere to the glove material or the sample ignites, the test will fail.
