Standards and Marking

All COFRA’s gloves are engineered to grant protection to workers, in the foreseeable conditions of end use. The performances of PPE are expressed by a pictogram alongside the markings. They are certified according to laboratory tests.

EN 420:2003+A1:2009 - Protective gloves - General requirements and test methods

It defines the requirements for glove design and construction, innocuousness, sizes, dexterity and marking. The compliance with EN 420:2003+A1:2009 is compulsory for any kind of gloves, however marking is not strictly required. Any further technical information is in the information sheet included in the packaging.


Dexterity is the the capacity to handle tools and make movements when wearing gloves. According to the intended use, the glove should provide the maximum dexterity allowed. It depends on several factors, e.g. the thickness of the glove material, its elasticity, its deformability. COFRA carries out the dexterity test on each glove, so that the best application can be selected. EN 420:2003+A1:2009 standard defines different performance degrees in a range from 1 (low dexterity) up to maximum 5 (maximum dexterity).


Art. LIMBER (dexterity 5), it allows to handle with high precision even very small tools



Art. INOX (dexterity 3), it guarantees high protection and resistance, while keeping a dexterity degree suitable for the intended application

EN 388:2016 - EN 388:2003 Updated European Standard

Revision of EN 388 standard, applied to mechanical protective gloves, increases accuracy and reliability of cut tests. The current EN 388:2003 describes the test method called Coupe Test which calculates the number of cycles needed to cut the glove at 5N pressure (500 g about).
EN 388:2016 adds a second test, TDM Test specifi ed by EN ISO 13997:1999 (straight blade, moving at a predetermined distance, subjected to variable force) which will be used for cut resistant gloves, whereas it will be optional for less resistant gloves, which will tested by Coupe Test.

Protection gloves against mechanical risks must have a performance level equal to 1 or higher for at least one of the properties (abrasion, blade cutting, tear and perforation) or at least a level A of the EN ISO 13997:1999 TDM cutting resistance test; classified according the minimal requirements for each level which is shown in the following scheme:

EN ISO 374-1:2016 (replace EN 374-1:2003) - Protective gloves against dangerous chemicals and micro-organisms


Part 1: Terminology and performance requirements for chemical risks
Specifies the requirements for protective gloves intended to protect the user against dangerous chemicals and defines terms to be used.

EN 374-2:2014 (replace EN 374-2:2003) - Protective gloves against dangerous chemicals and micro-organisms


Part 2: Determination of resistance to penetration
Specifies a test method for the penetration resistance of gloves that protect against dangerous chemicals and/or micro-organisms.
The tested gloves must pass the air leakage test (verifying the absence of holes on the surface after the pressurization with air of the inner part of the glove) and / or the water leakage test (verifying the absence of drops on the external surface after filling the glove with water). Such tests must be carried out in compliance with requirements and acceptable quality levels (AQL) of ISO 2859 standard, provided and / or established for quality assurance during production. The AQL (Accepted Quality Level) evaluates the quality of each production batch determining the probability of finding holes. For this reason a lower AQL (for example 0.65 rather than 1.5) will correspond to a lower statistical probability of finding defects / holes.

EN 16523-1:2015 (replace EN 374-3:2003) - Determination of material resistance to permeation by chemicals


Part 1: Permeation by potentially hazardous liquid chemicals under conditions of continuous contact
Specifies a test method for the determination of the resistance of gloves to permeation by potential hazardous liquid chemicals under the condition of continuous contact (this test method is not adapted for the assessment of chemical mixtures, except for aqueous solutions).
The permeation resistance of these chemical products is evaluated by measuring their relative crossing time from the outer surface of the glove to the internal surface in contact with the skin . Based on this measurement, the glove resistance is established by the reference permeation performance level by a range of value from 1 to 6, as quoted here below:
> 10 1
 > 30 2
 > 60 3
 > 120 4
 > 240 5
 > 480 6

The list of chemical products that can be tested according to EN 16523-1 standard: 2015 includes, in addition to 12 chemical products already mentioned in the previous EN 374-3:2003 standard (concerning the letters from A to L), further 6 chemical products (concerning the letters from M to T) for a total of 18 chemical products listed here below.

 S 40% Hydrofluoric acid   7664-39-3  Inorganic mineral acid
 T  37% Formaldehyde  50-00-0  Aldehyde

According to their permeation performances, chemical protective gloves are classified into three types (starting from 21/04/2018 according to EN 16523-1:2015 standard):

Penetration Permeation
 Type A  016c  Protective gloves must not show
any leak when subjected to air
leakage and water leakage tests.
 Permeation performance must
be at least level 2 for a minimum of
six test chemical products.
 Type B  016d  Protective gloves must not show
any leak when subjected to air
leakage and water leakage tests.
 Permeation performance must
be at least level 2 for a minimum of
three test chemical products.
 Type C  016e  Protective gloves must not show
any leak when subjected to air
leakage and water leakage tests.
 Permeation performance must
be at least level 1 for a minimum of
one test chemical product.

During the transition period that will last until the 21th of April 2023 it will be possible to find the pictograms relating to the previous EN 374-3: 2003 standard, that is:   


Protection against chemicals

The glove marked with the pictogram on the side achieves a minimum permeation performance level of 2 for at least three chemicals.


Impermeability to water and low chemical protection
A glove marked with this pictogram (“Low chemical protection and impermeability to water”) complies with the penetration test and reaches a permeation performance level of at least 2 (a breakthrough time of at least 30 minutes) for less than three chemicals on the list.

EN 374-4:2013 - Protective gloves against chemicals and micro-organisms


Part 4: Determination of resistance to degradation by chemicals
It specifies the test method for the determination of the resistance of protective glove materials to degradation by dangerous chemicals with continuous contact.
The deterioration due to the contact with chemical product is a damaging change of one or more characteristics of the protective glove material. Among these changes it is possible include: break-up, swelling, disintegration, embrittlement, color variations, dimension variations, look, hardening and softening.
This resistance to deterioration is determined by measuring the percentage of perforation resistance of glove material due to continuous contact ( for an hour) of glove external surface with the tested chemical product.

EN ISO 374-5:2016 - Protective gloves against dangerous chemicals and micro-organisms


Part 5: Terminology and performance requirements for micro-organisms risks
It specifies the requirements and test methods for protective gloves intended to protect the user against micro-organisms, that means against those microbiological agents such as bacteria, virus or fungi. The gloves that have not leakage when they are tested to penetration resistance defined by EN 374-2:2014 standard are considered as resistant to bacteria and fungi, so they pass both air and water leakage test. On the other hand, gloves that are tested according to ISO 16604:2004 standard (procedure B) that do not show any detectable transfer ( < 1 PFU/ml) of ) PHI- X174 bacteriophage are considered as resistant to viruses (as well as bacteria and fungi).

EN 16350:2014 – Protective gloves - Electrostatic properties


This European Standard provides additional requirements for protective gloves that are worn in areas where flammable or explosive areas exist or might be present. It specifies a test method and requirements for performance, marking and information for electrostatic dissipative protective gloves to minimize explosion risks. This European Standard does not cover: - protection of electronic devices; - protection against mains voltages; - insulative protective gloves for live working (EN 60903); - protective gloves for welders (EN 12477).

EN 1149-2:1997 - Protective clothing - Electrostatic properties

Part 2: Test method for measurement of the electrical resistance through a material (vertical resistance)

This European Standard specifies a test method for measuring the electrical vertical resistance of protective clothing materials. This European Standard is not applicable for specifying protection against mains voltages.

EN 1149-1:2006 - Protective clothing - Electrostatic properties

Part 1: Test method for measurement of surface resistivity


 This standard specifies a test method for materials used in the production of electrostatic dissipative protective clothing (or gloves), to avoid incendiary charges.


EU Directive 1999/92/EC - ATEX (ATmosphères EXplosibles)


The EU Directive 1999/92/EC (Atex Directive) indicates the requirements for safety and health protection of workers potentially exposed to the risk of explosive atmospheres. COFRA gloves comply with all requirements about the materials and the designing required by the standard UNI EN 16350:2014 (electrostatic properties): they avoid that electrostatic discharges cause fires, thus making the glove suitable to be used in ATEX environments (CEN/CLC/TR 16832:2015).

EN ISO 17231:2011 – Leather - Physical and mechanical tests - Determination of water repellency of garment leather


The water repellency of the leather layer is evaluated by determining the percentage of water absorbment. The result is expressed in percentage terms.

EN ISO 14419:2010 – Textiles - Oil repellency - Hydrocarbon resistance test



The resistance of a substrate to oil absorption is evaluated by testing the resistance to absorption of a selected series of liquid hydrocarbons of different surface tensions. The result can reach grades between 0 and 8.

European food contact regulations


The products intended to be in direct contact with food must bear the symbol “glass and fork”, complying with EC no.1935/2004 regulation (“Materials and items intended to come in contact with food”) and especially the gloves have to comply with the more specific EU no.10/2011 Regulation (“Plastic materials and items intended to come in contact with food”). This means that all the materials used to manufacture gloves must not pose a danger to human health and they must not cause any change in the composition or a deterioration of foodstuffs. For this purpose the foodstuffs are classified into 5 groups and the compliance of gloves in contact with any of them is tested. Therefore a glove can be suitable for the contact with some groups of food and not suitable for others. For correct information about the kinds of food for any glove, the manufacturing companies must issue information through the Declaration of Conformity.
