Gloves giving protection from mechanical risks
Protection against mechanical hazards is expressed by a pictogram followed by four numbers (performance levels), each representing test performance against a specific hazard.
1 Resistance to abrasion
Based on the number of cycles required to abrade through the sample glove (abrasion by sandpaper under a stipulated pressure). The protection factor is then indicated on a scale from 1 to 4 depending on how many revolutions are required to make a hole in the material. The higher the number, the better the glove. See table below.
2 Blade cut resistance
Based on the number of cycles required to cut through the sample at a constant speed. The protection factor is then indicated on a scale from 1 to 4.
3 Tear resistance
Based on the amount of force required to tear the sample.
The protection factor is then indicated on a scale from 1 to 4.
4 Puncture resistance
Based on the amount of force required to pierce the sample with a standard sized point. The protection factor is then indicated on a scale from 1 to 4.
