EN388 2016 Test Performance levels Glove Score
Abrasion resistance 1-4 (4 Max Score) 3
Cut resistance (Coupe Test) 1-5 (5 Max Score) 1
Tear resistance 1-4 (4 Max Score) 0
Puncture resistance 1-4 (4 Max Score) 1
Cut resistance TDM Test (EN ISO 13997) A-F (F highest Cut Resistants) A
ABRASION RESISTANCE: The material is subjected to abrasion by a sandpaper under a determined pressure. The protection level is indicated on a scale of 1 to 4 depending on the number of turns required until a hole appears in the material. The higher the number is, the better the resistance to abrasion. CUT RESISTANCE, COUP TEST: The cut protection is tested. A knife is passed over the glove material until it cuts through. The protection level is given by a number between 1 and 5, where 5 indicates the highest cut protection. If the material dulls the knife during this test, the cut test ISO 13997(TDM test) shall be performed instead, see point 5. TEARING STRENGTH: The force required to tear the glove material apart is measured. The protection level is indicated by a number between 1 and 4, where 4 indicates the strongest material. PUNCTURE RESISTANCE: Based on the amount of force required to puncture the material with a tip. The protection function is indicated by a number between 1 and 4, where 4 indicates the strongest material. CUT RESISTANCE, TDM TEST ISO 13997: If the knife gets dull during the coup test, see point 2, this test shall be performed instead. The result is given by a letter, A to F, where F indicates the highest level of protection. If any of these letters is given, this method determines the protection level instead of the coup test. ISO 13997:1999 – Determination of resistance to cutting by sharp objects An alternative cut test recommended for cut protection gloves. Shall be used in EN388:2016 for cut protection gloves where the cut material dulls the cutting knife during testing. A knife cuts with constant speed but increasing force until breakthrough of the cut protection material. Level of protection is given in Newton, the force needed for cut through at 20mm cut length.

J n-Heptane
K Sodium Hydroxide 40%
L Sulphuric Acid 96%
PERMEATION The chemicals break through the glove material at a molecular level. The breakthrough time is here evaluated and the glove must withstand a breakthrough time of at least: Type A – 30 minutes (level 2) against minimum 6 test chemicals Type B – 30 minutes (level 2) against minimum 3 test chemicals Type C – 10 minutes (level 1) against minimum 1 test chemical
