Gloves Mechanical Risks |
Protection against mechanical hazards is expressed by a pictogram followed by four numbers (performance levels), each representing test performance against a specific hazard.
- Resistance to abrasion
Based on the number of cycles required to abrade through the sample glove (abrasion by sandpaper under a stipulated pressure). The protection factor is then indicated on a scale from 1 to 4 depending on how many revolutions are required to make a hole in the material. The higher the number, the better the glove.
See table below.
- Blade cut resistance
Based on the number of cycles required to cut through the sample at a constant speed. The protection factor is then indicated on a scale from 1 to 5.
- Tear resistance
Based on the amount of force required to tear the sample.
The protection factor is then indicated on a scale from 1 to 4.
- Puncture resistance
Based on the amount of force required to pierce the sample with a standard sized point. The protection factor is then indicated on a scale from 1 to 4.

Gloves Thermal Protection |
The nature and degree of protection is shown by a pictogram followed by a series of six performance levels, relating to specific protective qualities. The higher the number, the better the test result. The following is tested:
1 Resistance to flammability
The glove’s material is stretched and lit with a gas flame. The flame is held against the material for 15 seconds. After the gas flame is distinguished, the length of time is measured for how long the material either glows or burns.
2 Resistance to contact heat
The glove’s material is exposed to temperatures between +100°C and +500°C. The length of time is then measured for how long it takes the material on the inside of the glove to increase by 10°C from the starting temperature (approx. 25°C). 15 seconds is the minimum accepted length of time for approval. For example: to be marked with class 2, the glove’s inside material must manage 250°C heat for 15 seconds before the material exceeds 35°C.
3 Resistance to convective heat
The amount of time is measured for the heat from a gas flame (80Kw/kvm) to increase the temperature of the glove’s inside material by 24°C.
4 Resistance to radiant heat
The glove’s material is stretched in front of a heat source with an effect of 20-40 kw/kvm. The average time is measured for heat penetration of 2.5 kw/kvm.
5 Resistance to small splashes of molten metal
The test is based on the total number of drops of molten metal required to increase the temperature by 40°C between the inside of the glove and the skin.
6 Resistance to large splashes of molten metal
Simulated skin is attached to the inside of the glove material. Molten metal is then poured over the glove material. The total number of grams is measured of how much molten metal is required to damage the simulated skin.

Gloves Manual Welding |
Protective Glove for Welders.
describes the design specifications for gloves that provide hand and wrist protection for welding and for similar work and should be referred to in conjunction with EN 388 and EN 407. This standard is applicable only in combination with EN 420, excluding that standard’s specifications concerning minimum glove length. Welding gloves must provide protection against mechanical hazards as well as small splashes of molten metal, short contact exposure to limited flame, short exposure to convective heat, against UV radiant heat from arc and against contact heat.
According to their comparative performance levels, protective gloves for welders are divided into two categories:
Type A = gloves that provide a high degree of protection against heat but are less flexible
Type B = gloves that provide a lower degree of protection against heat but are more flexible
Marking conforms to specifications in EN 420 and to the pictograms in EN 388 and EN 407. |

Gloves Medical Single Use |
This includes tests to assess the freedom from holes which is based on a penetration resistance test similar to that of EN 374 Part 2, plus tests to assess the dimensions of the gloves and the mechanical strength of its materials, both before and after an ageing process.
EN 455 was originally written to support the Medical Devices Directive, but since the various amendments enabling CE marking of products as both Medical devices and PPE, the annex ZAs of more recent versions of EN 455 also make reference to the PPE Directive.
Part 1
EN 455-1 covers requirements and testing of gloves for freedom from holes. For this the standard uses a water leak test that is carried out using AQL statistical sampling techniques based on production batch sizes.
Part 2
EN 455-2 covers requirements and tests for physical properties such as dimensions (length & width) and force at break both before and after heat ageing.
Part 3
EN 455-3 covers requirements and tests for biological evaluation.
This part of the standard includes test procedures for measuring endotoxin contamination of sterile gloves, powder residue for powder free gloves and leachable proteins in natural rubber latex gloves.
Part 4
Covers requirements and testing for shelf life determination.
This part of the standard covers protocol to be followed to evaluate the gloves shelf life by using real time studies or a suitably validated alternative. |

Gloves Mechanical |
Protection against mechanical hazards is expressed by a pictogram followed by four numbers (performance levels), each representing test performance against a specific hazard.
- Resistance to abrasion
Based on the number of cycles required to abrade through the sample glove (abrasion by sandpaper under a stipulated pressure). The protection factor is then indicated on a scale from 1 to 4 depending on how many revolutions are required to make a hole in the material. The higher the number, the better the glove.
See table below.
- Circular Blade cut resistance
Based on the number of cycles required to cut through the sample at a constant speed. The protection factor is then indicated on a scale from 1 to 5.
- Tear resistance
Based on the amount of force required to tear the sample.
The protection factor is then indicated on a scale from 1 to 4.
- Puncture resistance
Based on the amount of force required to pierce the sample with a standard sized point. The protection factor is then indicated on a scale from 1 to 4.
- ISO 13997 Cut Test
Determination of resistance of the glove to cutting by a sharp object through single contact under higher force.
Here, a long, straight blade is drawn once over the test piece. The minimum force required to cut through the test piece after 20 millimetres is determined in the process.
The result is given in newtons (N) and assigned to a cut protection class. On a Scale A-F
- Impact Protection
An optional test based on the mean transmitted force. Test is carried out in accordance with EN13594 : 2015 6.9.
If the glove meets the requirement , a P for pass is added as the last digit to the glove marking.

Gloves Cold Performance |
specifies the requirements and test methods for gloves which protect against convective and conductive cold down to -50 °C. This cold can be linked to the climatic conditions or an industrial activity. The specific value of the different performance levels are decided by the special requirements for each class of risk or the special areas of application.
The gloves insulation properties may be affected by for example air temperature, humidity, wind speed, time of exposure, activity level, health and well being of the user. If wet, the glove may lose its insulative properties. Test Levels Convective cold 0 – 4, where 4 is best {Method The convective cold test is a more complex procedure. The apparatus required for this latter test includes a heated hand in an environmental chamber that is set to a temperature at least 20ºC below that of the heated hand, and has a defined air flow rate. The principle of the assessment is to determine the electrical power required to maintain a constant temperature gradient between the surface of the heated hand and the atmosphere within the environmental chamber. The more electrical power that is required, the lower the thermal insulation value of the glove.}
Contact cold 0 – 4, where 4 is best [Method . The contact cold test involves the glove materials being placed between metal plates which are at different temperatures. The measured temperature drop across the test specimen is used to calculate its thermal resistance.]
Capability of resisting water (5 min.) 0 or 1 * * 0 = Water penetration after 5 min, according to EN 511:2006,
If the results have an X = The glove has not been submitted to the test or the test method appears not to be suitable for the glove design or material. |
