EN374 Test Standard

CTOPEAGE/Guangzhou Sunway Tech Co., Ltd./EN374 Certificate
EN 374 is a chemical-resistant glove standard that was last modified in 2016. It has wide scope, testing a glove's response to a wide range of chemicals while taking into account permeability, breakthrough time, shrinkage and more. The standard is divided in five sections which can be viewed below:
- EN 374 - 1: Protective Gloves Against Chemicals and Micro-Organisms
- EN 374 - 2: Determination to Resistance to Penetration
- EN 374 - 3: Determination of Resistance to Permeation by Chemicals (replaced by EN 16523)
- EN 374 - 4: Determination of Resistance to Degradation by Chemicals
- EN 374 - 5: Terminology and Performance Requirements for Micro-Organism Risks
EN 374 -1:
Protective Gloves Against Chemicals and Micro-Organisms
Most chemical resistant gloves will be tested to EN 374 - 1. EN 374 - 1 will test your gloves to a total of 18 different chemicals before awarding them with a certification of either A, B or C depending on how resistant the glove is to chemicals. Finally, this standard also includes a logo that quickly informs the user of which chemicals the glove can be used with.
- Type A: Protective glove with permeation resistance of at least 30 minutes with at least six test chemicals
- Type B: Protective glove with permeation resistance of at least 30 minutes with at least three test chemicals
- Type C: Protective glove with permeation resistance of at least 10 minutes with at least one test chemical
EN 374 -2:
Protective Gloves Against Chemicals and Micro-Organisms Determination to Resistance to Penetration
EN 374 - 2 can be identified by the standard below. It is designed to determine a gloves resistance to penetration by chemicals, something that is identified by testing the gloves to leakage when air and water is pressed through the gloves. The gloves are inner-pressured, filled with air or water before being measured for leakage afterwards.
Under EN 374 - 2 a glove can achieve three different results:
- EN 374 - 2: 1 - Waterproof
- EN 374 - 2: 2 - Waterproof / Micro-Organism Resistant
- EN 374 - 2: 3 - Waterproof / Micro-Organisms Resistant
EN 374 -3:
Protective Gloves Against Chemicals and Micro-Organisms: Determination of Resistance to Permeation by Chemicals
EN 374 - 3 has been replaced by EN 16523-1.
EN 374 -4:
Protective Gloves Against Chemicals and Micro-Organisms: Determination of Resistance to Degradation by Chemicals
EN 374 - 4 is designed to take into account how long it will take for a glove to degrade. Degrading can be caused by:
- Degradation (Change in a glove material)
- Degradation can cause brittelness, swelling or shrinkage
- A standardised measurement method for degradation for the first time
EN 374 -5:
Protective Gloves Against Chemicals and Micro-Organisms: Terminology and Performance Requirements for Micro-Organism Risks
The final part of EN 374 is EN 374 - 5, which describes if a glove is suitable for use with biological agents. The two parts of the standard are represented by two symbols which can be viewed below. The only criteria in terms of results for this standard are if the gloves achieve the standard, or if they do not.
