Standards and Markings

European standards have been developed to unify national provisions relating to PPE across the Member States. Council Directive 89/391/EEC sets broad guidelines for health and safety at workplaces and places a duty for the employer «to make appropriate personal protective equipment available to their staff». 
It also introduces strict requirements for PPE suppliers. Now, these requirements are acknowledged internationally helping employers to choose the right PPE, including protective gloves.

General Requirements

Categories

In order to comply with a number of requirements in the commercial sector, protective gloves are separated into three categories:

Category I:     For minimal risks.
Category II:    For intermediate risks, e.g. mechanical risks.
Category III:   For irreversible or mortal risks, e.g. injuries from chemicals.

A declaration of conformity is required for all categories. The manufacturer or importer must provide a declaration of conformity upon request.

GENERAL REQUIREMENTS FOR PROTECTIVE GLOVES

The European Standard EN 388:2016 covers the test requirements for safety gloves that are provided to protect against mechanical risks, which covers abrasion, blade cut, puncture, tearing and impact.

The EN 388:2016 Standard is a revised version of the former EN 388 Standard (EN 388:2003). It has increased the scope of testing required, and the test results thus provide customers with more information, helping them to make the right choice of hand protection for their needs.

EN 388:2016
ABCDEF
AAbrasion resistance
BCircular blade cut resistance
CTear resistance
DPuncture resistance
EStraight blade cut resistance
FImpact protection

 

AAbrasion resistance
 Based on the number of cycles needed to abrade through a sample of the glove. Samples are cut from the glove palm and rubbed against sandpaper of a certain quality under a certain constant pressure as defined by the standard. The level of abrasion resistance is measured by the number of cycles reached when a hole appears on the relevant glove sample.

 

BCircular blade cut resistance
 Based on the number of cycles required to cut through a sample of the glove palm with a circular, counter-rotating blade.

 

CTear resistance
 Based on the amount of force required to tear a sample of the glove apart.

 

DPuncture resistance
 Based on the amount of force required to penetrate the sample with a defined stylus. This is not an indication of the resistance to sharply pointed objects, e.g. hypodermic needle.

 

EStraight blade cut resistance, EN ISO 13997
 In the recently revised EN 388 Standard (EN 388:2016), the Circular blade cut resistance test is still in use, and the results from this test are applicable to gloves that do not dull the blade. However, materials that noticeably dull the blade during this test, are now to be tested according to the newly included EN ISO 13997 Straight blade cut resistance test. In these cases, the Circular blade cut resistance test results must be recorded as X (not applicable).

EN ISO 13997 determines the force in Newtons (N) required to cut through a material sample.

 

DImpact Protection
 Gloves that have specific impact resistant properties on the back of the hand can be tested against an updated EN 13594:2015 standard.
 
In this test, the glove knuckles are impacted by a 2.5 kg flat face striker from a sufficient height, creating an impact energy of 5J. If the sample has achieved a result of Level 1, the letter «P» is added to the results.

Protective Gloves against Mechanical Risks

This standard applies to all protective gloves in respect of physical and mechanical stress caused by abrasion, cut, tearing and puncture.

Protection against mentioned hazards is expressed by a pictogram followed by four numbers (performance levels), each representing test performance against a specific hazard.

EN 388abcd
  • aAbrasion resistance (x, min. 0, max. 4)
  • bBlade cut resistance (x, min. 0, max. 5)
  • cTear resistance (x, min. 0, max. 4)
  • dPuncture resistance (x, min. 0, max. 4)

Level X means that this test cannot be carried out on this particular glove. The higher the level, the better performance

A - Abrasion resistance
Based on number of cycles needed to abrade through a sample of glove. Samples are cut from glove palm and rubbed against a standard sand paper under a constant standard pressure. Number of cycles is measured when a hole appears on any of the samples.

B - Blade cut resistance
Based on the number of cycles required to cut through the sample from glove palm by circular, counter-rotating blade.

C - Tear resistance
Based on the amount of force required to tear the sample apart.

PROTECTIVE GLOVES AGAINST CHEMICALS AND MICRO-ORGANISMS

This standard specifies the requirements against which the capacity of a glove to act as a protective barrier against chemicals and/or micro-organisms is tested.

It consists of five parts:

  • PART 1: Mechanical and physical integrity.
    (EN ISO 374-1:2016)
  • PART 2: Resistance to penetration.
    (EN 374-2:2014)
  • PART 3: Resistance to permeation by chemicals.
  • (EN 374-3:2016/EN 16523-2015)
  • PART 4: Resistance to degradation by chemicals.
    (EN 374-4:2013)
  • PART 5: Performance requirements for micro-organisms risks.
    (EN ISO 374-5:2016)

Part 2: RESISTANCE TO PENETRATION

Penetration is a physical process whereby a liquid or air penetrates a fabric by passing through pores, seams or pinholes in the fabric.

Two tests are performed in this part of EN 374:2014:

  • Air leak test: The glove is inflated with air pressure and submerged into a tank of water. Leaks are identified by visible bubbles.
  • Water leak test: The glove is filled with water and its outer surface is examined for water drops.

Part 3: RESISTANCE TO PERMEATION BY CHEMICALS

New permeation test method EN 16523-1:2015 replaces EN 374-3:2003.

Permeation is a process by which a potentially hazardous chemical moves through a material on the molecular level. In the laboratory, permeation is measured by a parameter called breakthrough time.

Breakthrough time is the time a potentially hazardous chemical takes to permeate through the glove material and reach the inside of the glove.

It is determined by applying a potentially hazardous chemical to the exterior surface of the glove and measuring the time it takes before the chemical is detected on the inside surface. It gives an indication of how long a glove can be used with a certain chemical.

PERFORMANCE LEVEL123456
BREAKTHROUGH TIME (Min)≥ 10≥ 30≥ 60≥ 120≥ 240≥ 480


Although tests are performed according to the standard, factors such as temperature and stretching have a great influence on how fast the chemical permeates through the glove material. Granberg recommends a 25% safety margin.

EN 374:2016 defines a list of 18 chemicals (6 chemicals are new)

List of test chemicals specified in EN ISO 374-1:2016:

Part 4: RESISTANCE TO DEGRADATION BY CHEMICALS

In order to claim that a glove provides protection against a chemical on the list, permeation and degradation tests must be carried out. The results of the degradation test must appear in the User Instructions.

The principle of this test is to assess if a change of a certain nature has occurred in the glove after continuous contact with a chemical. It is de­ter­mined by a puncture resistance test similar to that of EN 388:2016.

Part 5: PERFORMANCE REQUIREMENTS FOR MICRO-ORGANISMS RISKS

Protection against bacteria and fungi can be claimed if penetration (EN374-2:2013) and EN 420 general requirements are met.
It is possible to declare that a glove provides protection against viruses if it meets the requirements of ISO 16604:2004 procedure B.

Protective gloves against chemicals and micro-organisms

This standard specifies gloves capability to act as a barrier against chemicals and/or micro-organisms. It consists of three parts:

  • Part 1: Mechanical and physical integrity (according to EN 388:2003)
  • Part 2: Resistance to penetration (EN 374-2:2003)
  • Part 3: Resistance to permeation by chemicals (EN 374-3:2003)

Part 2: Resistance to penetration (EN 374-2)

EN374-2 EN 3882
Penetration is a physical process whereby a liquid or air penetrates a fabric by passing through pores, seams or pinholes in the fabric

Two tests are performed in this part of EN 374:2003:

  • Air leak test. Glove is inflated with air pressure and submerged into a tank of water. Leaks are identified by visible bubbles.
  • Water leak test. Glove is filled with water and its outer surface is examined for water drops.

Gloves should not leak and should be inspected in compliance with the acceptable quality level (AQL).

Performance levelAcceptable quality level (AQL)
3<0,65
2<1,5
1<4,0

The higher the level, the better performance.

A glove is considered as offering protection against bacteria and molds if it achieves at least penetration level 2.

Part 3: Resistance to permeation by chemicals (EN 374-3:2003)

Permeation is a process by which a potentially hazardous chemical moves through a material on a molecular level. In the laboratory, permeation is measured by a parameter called breakthrough time.

Breakthrough time is the time a potentially hazardous chemical takes to permeate through the glove material and reach the inside of the glove. It is determined by applying a potentially hazardous chemical to exterior surface of the glove and measuring the time taken until chemical is detected on the inside surface. It gives the indication for how long a glove can be used with a certain chemical.

Medical Gloves for Single Use


This standard specifies requirements and tests for gloves for medical purpose. Requirements are detailed in the Medical Device Directive 93/42/EEC.
This includes tests to assess the freedom from holes, the dimensions of the gloves and the mechanical strength of its materials, both before and after an ageing process.

Part 1
EN 455-1 covers requirements and testing of gloves for freedom from holes. For this test the standard uses a water leak test to which randomly sampled gloves are subjected. A statistical sample taken from a batch must achieve an acceptable quality level (AQL) of 1.5 or better in order to be used as examination, procedure or surgical gloves.
AQL 1.5 is equivalent to a maximum risk of 1.5% that any given glove contains a pinhole capable of allowing water, and therefore micro-organisms, through the material.

Part 2
EN 455-2 describes the testing requirements for determination of physical properties, including tensile strength, before and after accelerated ageing, of medical gloves.  Gloves are treated differently depending on the use they are intended for and the material they are manufactured from.

Part 3
EN 455-3 covers requirements and testing for biological evaluation. It specifies methods for protein testing (extractable latex proteins have an important role in latex allergy), powder levels, and endotoxin levels.

Part 4
EN 455-4 covers requirements and testing for shelf life determination. It specifies real-time and accelerated shelf life studies, to enable manufacturers to prove that their product will withstand up to 3 years (usually) without losing their properties as well as complying with the requirements of the EN 455.
