The EN 388 standard defines criteria for protection against mechanical risks, including abrasion, cut, puncture, and tear, represented by a pictogram followed by four numbers indicating performance levels.
1st Level: Abrasion resistance (0 to 4): Refers to the number of cycles required to deteriorate the sample at a constant speed.
2nd Level: Cut resistance (0 to 5): Indicates the number of cycles required to cut the sample at a constant speed.
3rd Level: Tear resistance (0 to 4): Measures the force required to tear the sample.
4th Level: Puncture resistance (0 to 4): Evaluates the force required to puncture the sample with a standardized punch.
