European legal standards.
European standards for protective gloves.
Before presenting the various standards on PPE, we would like to inform you that GUYARD establishments have been ISO 9002 certified since 1998. The ISO 9002 standard is the quality assurance of production, installation and related services.
Categories of PPE according to the risks
There are 3 main categories of PPE according to the risks:
MORTAL RISKS OR

Pictograms of European standards
The specificity of our gloves are indicated by standardized pictograms.
These pictograms are also used for the marking of protective gloves.
Characteristics of materials
NEOPRENE : greater flexibility and greater chemical protection
NITRILE : excellent resistance to abrasion
PVC : protection against liquids and solvents
RUBBER : adhesion, resistance to cuts and punctures
VINYL : breathable, good adhesion, good permeability to water, oil and grease
NATURAL LATEX : good acid permeability and good mechanical resistance
LEATHER : good resistance to abrasion, cuts, tears and perforations
TYPE II and TYPE III gloves
The performance of the gloves is evaluated according to the criteria of the European Standards below and symbolized by pictograms which are accompanied by figures representing the performance levels.
|Correspondence of figures:|
|X||Performance level not tested|
|4 and +||Excellent|
EN 420 : General requirements
This European standard corresponds to the general requirements for protective gloves.
- Absence of chromium (2 mg/kg)
- Neutrality of PH
- Dexterity, Comfort
- Transmission and absorption of water vapor
EN 388 : Mechanical hazards
Protective gloves in accordance with EN 388 must first meet the requirements of EN 420 which we have just presented to you.
This standard certifies protective gloves against mechanical risks according to the following 4 specific risks:
|A. Abrasion||The abrasion resistance (4 levels) is measured by the number of cycles required to obtain glove wear.|
|B.Trenching||The cut resistance (5 levels) by slicing is measured by an index resulting from 5 tests. These tests are carried out according to the principle of the number of cycles necessary to cut the test sample "ee" which is compared with a control sample "and". (index = average of tests, test = and + ee / ee)|
|C. Tear||Tear resistance (4 levels) is expressed in Newton and corresponds to the force required to tear the sample.|
|D.Perforation||The resistance to perforation (4 levels) is also measured in Newton and corresponds to the force required to perforate the sample.|
|Trial||Level 1||Level 2||Level 3||Level 4||Level 5|
|Abrasion resistance (number of cycles)||100||500||2000||8000||-|
|Resistance to slicing cut (index)||1,2||2,5||5||10||20|
|Tear resistance (in Newtons)||10||25||50||75||-|
|Puncture resistance (in Newtons)||20||60||100||150||-|
Standard ISO 13997 CUTTING TEST TDM accepted in addition to EN 388.
The new version of EN 388 2003 incorporates another test method according to the international standard ISO 13997 on a TDM branded device.
This test method may be used in addition to the cut according to EN 388 2003 for levels greater than or equal to 4.
EN 388 2003 : The reference index is calculated according to the number of cycles performed by the blade on the specimen.
ISO 13997 - TDM : The reference index is calculated as a function of the force required to slice the specimen over a blade's travelling distance of 20 mm. The blade is changed at each test. The requirements of this test to obtain the level 5 are more severe than the EN 388 2003 standard. Thus this technique of slicing test guarantees a level of resistance to the cut more in phase with the reality of use of the products.
EN 407 : Thermal hazards
Protective gloves in accordance with EN 407 must first meet the requirements of EN 420 that we have previously presented to you. But also satisfy Level 1 of abrasion resistance, tearing of EN 388.
This standard certifies thermal protection gloves according to the following six specific risks:
|A. Fire Behavior||Fire performance tests classify gloves by level according to the length of time the flame persists (time elapsing between the time the glove is removed from the ignition source and the extinction flames) and according to the residual incandescence time (time that elapses from the extinction of the flame to the disappearance of the residual incandescence.
|B. Contact heat||Tests are used to establish performance levels by observing whether, after a time, the contact temperature passes through the glove and therefore would be detrimental to the user.|
|C. Convective Heat||Tests determine the time in seconds that each glove resists the heat produced by a flame. That is the time during which the glove prevents the transfer of heat to the hand.|
|D. Radiant heat||Tests determine the time in seconds for the glove to rise to radiant heat.|
|E. Small Splashes of Liquid Metal||Tests determine the time in seconds for the glove to rise to the level of radiant heat.|
|D. Radiant heat||The tests show the number of drops of molten metal that the glove is able to withstand before projections become a risk for its user.|
|F. Large Projections of Molten Metal||Tests show the amount of molten metal that the glove is able to withstand before the projections become a risk to its user|
|Trial||Level 1||Level 2||Level 3||Level 4|

EN 511 : Cold
Protective gloves in accordance with EN 511 must first meet the requirements of EN 420 which we have previously presented to you. But also satisfy the level 1 of abrasion resistance, tearing of EN 388.
|A. Convective cold||Convective cold Performance levels (4 levels) are established by thermal insulation levels. The tests are the observation of the conservation of the natural temperature of the hand in the glove at different levels of convective cold.|
|B. Contact cold||Contact cold Performance levels (4 levels) are established by thermal resistance levels. The tests are the observation of the conservation of the natural temperature of the hand in the glove at the surface contact of different levels of cold.|
|C. Impermeability to water||Impermeability to water A glove is considered impervious (level 1) if no penetration of water takes place for at least 30 minutes.|
EN 374: Chemicals and microorganisms
Protective gloves in accordance with EN 374 must first meet the requirements of EN 420 which we have previously presented to you. In addition, this standard imposes the precision of the performance levels of EN 388.
This standard certifies protective gloves against chemicals and microorganisms according to the following 2 specific risks:
|374.1 : Terminology and required performance|
|374.2 : Resistance to penetration||Penetration is the diffusion, on a non-molecular scale, of a chemical and / or a micro-organism through the porosities, seams, micro-holes or other imperfections present in the skin. glove material. Tests that meet the law of all or nothing allow to enter or not on the data sheet the acceptable quality level (AQL).
|374.3 : Resistance to permeation||Permeation is the process by which a chemical diffuses through the glove material at the molecular level. Resistance to permeation is determined by measuring the passage time of the chemical through the glove material.|
The following table shows the values necessary for the protective glove to be considered level 1, 2 ... for the permeation resistance of EN 374-3.
|Trial||Level 1||Level 2||Level 3||Level 4||Level 5||Level 6|
|Time of passage (in minutes)||10 mn||30 mn
||60 mn||120 mn||240 mn||480 mn|
EN 659: Firefighters gloves
Protective gloves according to EN 659 must first meet the requirements of EN 420 with the exception of the minimum glove lengths which must be in millimeters for sizes 6 to 11: 260, 270, 280, 290, 305, 315.
In addition, the EN 659 standard requires the minimum achievement of performance level 2 for all risks of EN 388.
Finally, the EN 659 standard requires the achievement of various levels of risk in EN 407. Performance level 4 is the highest in terms of fire behavior, at least level 2 for contact heat, at least level 3 for convective heat and at least 15 seconds of resistance to radiant heat in the middle of level 1. This standard certifies protective gloves against chemicals and microorganisms according to the following 2 specific risks: This standard certifies protective gloves for firefighters. Heat resistance of the lining material: This specific resistance to firefighters gloves involves no melting, drip, inflammation of the lining material closest to the skin.
The letter i in the pictogram indicates the obligation to consult the instructions of the manufacturer.
