EN388 Mechanical Risk Guide
EN 388 - 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 abrasionBased 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 resistanceBased 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 5. 3 Tear resistanceBased on the amount of force required to tear the sample. 4 Puncture resistanceBased 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. If some of the results are marked with a X means that this test performance is not tested. If some of the results are marked with a O means that the glove did not pass the test. |
