TOUTRAVO VE511

The reference standard cannot be used alone but only in combination with another standard containing protection performance requirements.
• Conform to harmlessness (pH, chrome VI levels, etc…).
• Conform to the size charts (see chart on below).
• Pass the dexterity test.
• Conform to the labelling, information and identification instructions.

STANDARDIZED LABELING/IDENTIFICATION
Each protective glove is clearly identified by a standardized label containing the following elements:
– Our brand logo.
– The product reference or the trade name.
– The size.
– An information tag indicating that instructions on the product are available.
– The standardization pictogram(s) with their performance ratings.

The EN388 standard applies to all types of protective gloves with respect to physical and mechanical aggression from abrasion, cutting from slicing, perforation and tearing. Since the 2016 version of the standard, new optional performances have appeared.

Impact resistance on the metacarpal area: if this performance is claimed, the “P” mark appears.

Cut by blade, 2 test methods:

EN388 6.2.: For low to middle risks of cutting. A circular blade on which a constant force of 5 N is applied, moves back and forth until the sample is cut. It measures the number of completed cycles and is credited with the corresponding level.

EN ISO 13997: For materials that blunt the blade during the EN388 6.2 test and/ or are particularly resistant, for high risk of cutting. A straight blade makes a single movement of 20 mm with a force of 2N, the test is repeated with a different force as many times as necessary until the sample is cut. A level corresponding to the force required to cut the sample is assigned. This method better represents the usage
situations that present a high risk of cutting.

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.
