Protective Gloves : General Requirements
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
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 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.
Protective Gloves : Mechanical Vibration and Shock
EN 10819: 1996
This European standard specifies a method for the laboratory measurement, the data analysis and rotting if the vibration transmissibility of gloves in terms of vibration transmission from a handle to the palm of the hand in the frequency range from 31.5 Hz to 1250 Hz. The standard is intended to define a screening test for the vibration transmission through gloves.
ANSI/ISEA 105-2011
American National a Standard for Hand Protection
This standard addresses the classification and testing of hand protection for specific performance properties related to chemical and industrials applications. Hand protection includes gloves, mittens, partial gloves, or other items covering the hand or a portion of the hand that are intended to provide protection against or resistance to a specific hazard.
