CE – EN 420:2003+A:2009
Class I = Protective gloves against minimal risks
General requirements for protective gloves
• Neutral pH (betweEN 3.5 and 9)
Innocuousness (neither the construction of the glove, nor the materials used, nor any degradation consequent on the normal use of the glove should be in any way harmful to the health or hygiene of the wearer)
• Specific for leather gloves: Chrome VI content
• Specific for natural rubber gloves: Extractable protein content
Class II = Protective gloves against intermediate risks
Conform to the European standard EN 420:2003 + performance level which shows how a glove has performed in a specific test for the mechanical risks accordingly to the EN 388:2003, and by which the results of that testing may be graded. Some gloves can also comply with specific applications like cold (EN511:2006), contact heat under 100°C (407:2004) and water tightness (EN 374-2:2003).
Standard EN 12477 :2001 + A1 :2005 – Minimum certification requirements for an adequate protection (hands and wrists) for welding and cutting; Exposure of short duration to a limited flame,
convective and/ or contact heat, UV radiation (curve, melted metal projection); Protection against mechanical attacks; The optional EN 1149-2 standard precise whether the glove provides the
minimal resistance of 100V. Two main types – Type A : glove with a lower dexterity level but with other higher performances – Type B : glove with higher dexterity level but with other lower
performances. The performance levels are classed in a increasing order, level 0 being the less performing one. These levels are always indicated in the same order next to the pictogram representing the standard.
EN 388:2003 – ABCD
Protective gloves against mechanical risks
A- Resistance to abrasion (0 to 4)
B – Resistance to blade cut (0 to 5)
C – Resistance to tear (0 to 4)
D – Resistance to puncture (0 to 4)
These levels are guaranteed on the palm of the glove.
EN 511 – ABC
Protective gloves against cold
A – Resistance to convective cold (0 to 4)
B – Resistance to contact cold (0 to 4)
C – Resistance to water (0 or 1)
EN 407: 2004 – EN 12477 Type A
Protective gloves against thermal risks (heat)
A – Resistance to flammability (0 to 4)
B – Resistance to contact heat (0 to 4)
C – Resistance to convective heat (0 to 4)
D – Resistance to radiant heat (0 to 4)
E – Resistance to small splashes of molten metal (0 to 4)
F – Resistance to large splashes of molten metal (0 to 4)
Protective anti-static gloves
Gloves for protection against irreversible risks; EN 374 : 2003 – Protective gloves against chemicals and micro-organisms
Class III EN 374 : 2003 – Gloves for protection against irreversible risks EN 374 : 2003 – Protective gloves against chemicals and micro-organisms
EN 374:2003 – ADF
The “Chemical hazards” gloves pictogram shall not leak when tested to an air and water leak test (EN 374 -2 ), and conforms to permeation performance at least level 2 of the three chemicals (EN 374-3) taken from the list as below.
A = Methanol ;
B = Acetone ;
C = Acetonitrile
D = Dichlorometahane ;
E = Carbon disulfide
F = Toluene ;
G = Diethylamine
H = Tetrahydrofuran ;
I = Ethyl acetate
J = n-heptane ;
K = Sodium hydroxide 40%
L = Sulfuric acid 96%
EN 374 – 3:2003
Permeation performance level The performance levels to permeation is the breakthrough time for a hazardous liquid to soak all the way through the glove as indicated hereafter :
Performance level – Breakthrough time
1 > 10 min.
2 > 30 min.
3 > 60 min.
4 > 120 min.
5 > 240 min.
6 > 480 min.
The “low chemical resistant” and “waterproof” gloves pictogram is to be used for glove which not achieve level 2 for three chemical from the defined list, but comply with penetration test.
EN 374 – 1:2003
A glove shall be conforms to the penetration test of
the following Acceptable Quality Levels (AQL)
• Level 3 must have an AQL on 0.65
• Level 2 must have an AQL on 1.5
• Level 1 must have an AQL on 4.0
