Protective Gloves : General Requirements
Protective Clothing: Electrostatic Properties
This European Standard specifies a test method for materials intended to be used in the manufacturing of electrostatic dissipative protective clothing (or gloves) to avoid incendiary discharge. This test method is not applicable for material to be used in the manufacturing of protection clothing or gloves against high voltages.
Protective Clothing – Electrostatic Properties – Part 5. Material
Performance and Deisgn Requirements.
This European standard is part of a series of standards for test methods and requirements for electrostatic properties if protective clothing. To standard specifies material and Design requirements for garments used as part of a total earthed system, to avoid incendiary discharges. The requirements may not be sufficient in oxygen enriched flammable atmospheres. This standard is not applicable for protection against mains voltages.
ESD – (Electrostatic Discharge)
ESD gloves are used to divert static electricity. Surface resistivitity is tested according to method specified in EN 1149-1 but test sample must meet the requirements EN1149-5.
EN420 : 2003 + A1 2009
This standard defines the general requirements for glove design and construction, innocuousness, cleaning instructions, electrostatic properties, sizing, dexterity, water vapour transmission and absorption along with marking and information
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.
