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

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

 08

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

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.

018 Protection against micro-organisms
The gloves are considered to be resistant to micro-organisms and constitute an effective barrier against fungi and bacteria, but not viruses, when they reach at least performance level 2 (AQL<1.5) of the penetration test. To determine the performance level, samples are taken and assessed in compliance with ISO 2859 from gloves in every production batch.

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

EN-ISO-17231-2011-WATER-REPELLENT2
 




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

EN-ISO-14419-2010-OIL-REPELLENT2
 

 



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

Normativa-Alimentare 


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.

OEKO-TEX®

OEKO-TEX 


OEKO-TEX® is a voluntary certification of product through which the certified company commits itself to keep in time the safeness of its own products. The OEKO-TEX® 100 mark guarantees that the textiles (or accessories of the textiles, metallic ones included) do not contain or release harmful substances for the consumer (pesticides, heavy metals, formaldehyde, aromatic amines, allergyinducing dyestuffs and so on). OEKO-TEX® certified gloves fully comply with the requirements of standard EN 420:2003+A1:2009 and they abide by the requirements of the attachment XVII of REACH (regulation 552:2009) having the textile product as area of pertinence.

REACH

00 

In order to safeguard the consumers’ health, the European Union issued the REACH regulation (come into force on 1st June 2007) which forbids the use of certain chemicals. COFRA guarantees that all its gloves comply with the REACH regulation; they do not contain forbidden or limited substances (Aromatic amines and 4-aminobenzoic acid deriving from azo dyes, heavy metals, phthalates, and so on) and, to guarantee it, all garments and accessories used during production are subjected to controls.
