Product Details

Standard EN ISO374-1, protective gloves against chemicals and micro-organisms, specifies the performance requirements required for gloves to protect users against chemical products and/or micro-organisms and defines the terms to be used :
• Penetration (tested as per standard EN374-2) :
Diffusion of water or air, to check the impermeability, on a non-molecular level, of a chemical product and/or micro-organism through the porosities, seams, micro-holes or other imperfections present in the material of the protective glove.
• Degradation (tested as per standard EN374-4) :
Determination of the physical resistance of materials to degradation after continuous contact with hazardous chemicals.
• Permeation (tested as per standard EN374-3 or EN16523) :
Process by which a chemical product diffuses through the material of a protective glove, by continuous contact, on a molecular level.
The EN ISO version of stadard EN374-1 introduces the concept of three types of protection agains the permeation of chemicals :
-Type A : The glove gives a performance index to permeation at least qual to 2 for 6 chemical test substances taken from the list of chemicals specified in the standard.
-Type B : The glove gives a performance index to permeation at least equal to 2 for 3 chemical test substances taken from the list of chemicals specified in the standard.
-Type C : The glove gives a performance index to permeation at least equal to 1 for 1 chemical test substances taken frome the list of chemicals specified in the standard.

EN ISO 374-5 specifies the requirements and test methods for protective gloves intented to protect the user against micro-organisms (mold and bacteria, potentially viruses).

Penetration of molds and bacteria (tested according to EN374-2): Test by which the water and airtightness of a glove is checked.
Penetration of viruses (tested according to method B of ISO 16604) : Process that determines the resistance to penetration by blood-borne pathogens - Test method using the Phi-X174 bacteriophage :



Examples of application :
The field of use is decisive because, depending on the case, the glove may have to combine several properties in order to meet the necessary protection requirements. It is therefore very important to refer to the recommended areas of use and the results of the laboratory tests found in the instructions for use. However, it is recommended to check that the gloves are suitable for the intented purpose by carrying out tests beforehand, because the conditions at the workplace may differ from those of the standard test, depending on the temperature, abraion and degradation.
