Knowledge Popularization: Protective Gloves’ Basic Standards
1. EN420 General Requirements
EN 420 also concerns the glove’s overall fit and feel by testing:
• Sizing and length
• Finger dexterity
Range: The standard indicates detailed requirements: ergonomic requirements, knitting, size, mark, and
Marks: Each pair of gloves needs to be marked with manufacturer’s name, style, and CE. If level 3,
testing laboratory name must be marked.
|Size|| Hand size(mm)|
| Min. length of|
|6||152 & 160||220|
|7||178 & 171||230|
|9||229 & 192||250|
|10||254 & 204||260|
|11||279 & 215||270|
Dexterity: It has 5 levels. During testing, tester picks up metal bars of different diameters to judge
PH value: All gloves must be tested PH value, and it should be within range between 3.5 and 9.5
2. EN388 Mechanical Risks
The standard states gloves’ protective functions against physical harm and mechanical risks, including
abrasion resistance, blade cut resistance, tear resistance, and puncture resistance.
|Character||Level 1||Level 2||Level 3||Level 4||Level 5|
(number of cycles)
|Blade cut resistance (index)||1.2||2.5||5||10||20|
|Tear resistance (N)||10||25||50||75||–|
3. Thermal Hazards
A general standard designed to be used for any glove which claims protection against cold environments. The standard includes two specific tests for assessing thermal insulation: convective cold and contact cold plus other low temperature performance tests in addition to requirements from EN 388 and EN 420.
EN 511: Compliance covers cold working hazards such as frozen gases. Performance levels range from
0-4; the higher the number, the higher the protection offered by the gloves.

4. Chemical Hazards
EN374 is the EU test standard for protective chemicals for gloves and microorganisms including some physical properties, mainly about the ability of protective gloves to resist penetration, permeation and degradation. Its applicable products are what we often call non-medical protective gloves, such as PVC protective gloves, nitrile protective gloves, mixed ding protective gloves, PET protective gloves and so on.
EN 374 regulations test gloves for penetration and permeation resistance against chemical and
micro-organism hazards. Results are scored 0-6, with a higher numbered result offering more safety.
|Letter Code||Chemical Product||Letter Code||Chemical Product|
|E||Carbon Disulphide||K||Sodium Hydroxide 40%|
|F||Toluene||L||Sulphuric Acid 96%|
