DO YOU KNOW 22

The EN407 heat and ame pictogram is accompanied by a 6 digit number. This 6 digit number identi es the performance levels (1-4) which a glove can achieve for each of the tests within the standard. The higher the performance level, the greater the protection of the glove against a range of thermal risks as described below: WHAT IS EN 407? F RESISTANCE TO LARGE SPLASHES OF MOLTENMETAL Measures the amount of molten iron (in grams) required to cause damage to“simulated skin”placed inside the glove. E RESISTANCE TO SMALL SPLASHES OF MOLTENMETAL Measures the speci c amount of molten droplets (from a meltedmetal rod), required to raise the inside temperature of a glove by 40c. D RESISTANCE TO RADIANT HEAT Measures the ability of a glove to resist heat from a radiant heat source. C RESISTANCE TO CONVECTIVE HEAT Measures the ability of a glove to resist heat from a ame source. B RESISTANCE TO CONTACT HEAT Measures the ability of a glove to resist heat when placed in direct contact with a heated object or hot surface. A RESISTANCE TO FLAMMABILITY Measures how likely a glove is to catch re after a ame is applied. 1 3 1 2 1 2 PROTECTIVE GLOVES AGAINST THERMAL RISKS EN 407
