EN388:2016-Mechanical Hazards
Protection against mechanical hazards in respect of physical and mechanical stress caused by abrasion, blade cut, tear and puncture. The table below indicates the glove’s resistance to:

4 = Abrasion 
X = Blade Cut* (coup)
4 = Tear 
2 = Puncture
F = Straight Blade Cut (EN ISO 13997) 

NOTES:
Where 1 indicates the lowest performance. X that the test was not performed or not possible. A 0 rating indicates that during the test level 1 was not reached.

*Gloves should not be used when working with serrated blades

EN ISO 374-1: Chemical Hazards
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 30 minutes against a minimum of 6 test chemicals.

J = n-heptane (142-82-5) Saturated hydrocarbon

K = 40% Sodium hydroxide (1310-73-2) Inorganic base

L = 96% Sulphuric acid (7664-93-9) Inorganic base

M = 65% Nitric acid (7697-32-2) Inorganic base

N = 99% Acetic acid (64-19-7) Organic acid

O = 25% Ammonium hydroxide (1336-21-6) Inorganic base 

EN407: 2020 Thermal risks (heat and/or fire)
This standard specifies thermal performance for protective gloves against heat and/or fire. The table below indicates the glove’s resistance to:

X = Flammability 
1 = Contact heat 
X = Convective heat 
X = Radiant heat 
X = Small splashes of molten metal 
X = Large splashes of molten metal 

NOTES:
Where 1 indicates the lowest performance. X that the test was not performed or not possible. A 0 rating indicates that during the test level 1 was not reached.
