Quality Criteria
In the EN 374 Standard, Part 1 details the performance criteria and also includes requirements to check the mechanical and physical integrity of the products.
 
Penetration resistance in part 2 is determined by subjecting the gloves to either air leak or water leak tests to determine if any holes are present which would allow chemicals to penetrate through to the users hand.
 
Part 3 specifies the determination of the resistance of protective glove materials to permeation by potentially hazardous non-gaseous chemicals under the conditions of continuous contact. Permeation is the process by which a chemical moves through a protective glove material on a molecular level. Gloves are classified according to the breakthrough time of the chemical through the glove material.
 
 
Quality Check Method
In Part 2: Determination of resistance to penetration, two tests are included, both to assess the resistance of the glove to penetration (or freedom from holes). First is the air leak test which involves inflating a glove with air pressure and then submerging it in a tank of water. Any leaks are identified by visible bubbles. The second test involves suspending a glove filled with water and examining its outer surface for water droplets.
 
In Part 3:Determination of resistance to permeation by chemicals, a sample of the glove material is placed in contact with a challenge chemical and the rate at which this chemical travels through (permeates) the material is determined. The breakthrough time is the time at which this permeation rate exceeds 1µg/cm2/min. The samples are assigned performance levels depending on this breakthrough time. In order to be certified as chemically protective, the gloves must achieve a minimum of level 2 (breakthrough time of greater than 30 minutes) against at least 3 chemicals listed in EN 374-1.
 
Experts consider an appropriate permeation test temperature of (33 ± 1) °C, which, as shown clearly in experiments, produces breakthrough times that are 30 to 50% lower than in the permeation test as specified in EN 374-3:2003, a much better results.
 
Quality Tolerance
 
This pictogram is displayed on gloves that comply to penetration and permeation requirements. Gloves that carry this symbol have been successfully tested against at least 3 different chemicals. The pictogram is accompanied by the relevant code letter(s) of these chemicals according to the following chart:
 
Code letter
Class
A
Primary alcohol
B
Ketone
C
Nitrile compound
D
Chlorinated paraffin
E
Sulphur containing organic compound
F
Aromatic hydrocarbon
G
Amine
H
Heterocyclic and ether compound
I
Ester
J
Saturated hydrocarbon
K
Inorganic base
L
Inorganic mineral acid
 
 
Depending on the workplace, the gloves are exposed both to the influence of body temperature and of the ambient temperature, i.e. they can be exposed to temperatures higher or lower than (33 ± 1) °C, which, in turn, can result in other breakthrough times.
 
 
This pictogram is displayed on gloves that are waterproof and give low chemical protection.
 
People/Quality Check Skills Required
Consult a qualified perofessional in the specific industry that the Chemical Resistant Gloves will be used (OSH- EXPERTS) taking in strict consideration and compliance to the standards should be reflected in the presence or absence of the pictograms above as seals of compliance.
Types
Type name is according to the main material which the glove is made of,hence,the major types of chemical resistant gloves are: natural rubber,neoprene rubber,butyl rubber,polyvinyl.nitrile rubbe.
