Safety Glove Standards Explained

Helping you select appropriately rated gloves

When deciding which gloves to use for a particular task, it's important to select a glove that provides workers with the appropriate protection as demonstrated by the relevant European (EN) or British (BS) standard.

These standards help to ensure that gloves are fit for purpose. Each standard specifies how gloves designed to protect against particular types of hazards should be tested, classified and labelled.


Protective Glove Standards for Different Hazards

All protective gloves must meet the basic standards described in EN ISO 21420 (General requirements and test methods). Depending upon their intended use, safety gloves may have been designed and tested to also comply with one or more of the following standards.


How Do I Know Which Standards a Glove Has Passed?

Each standard specifies what labelling needs to feature on gloves to help users identify the type and level of protection they offer. This includes a unique shield symbol - with the exception of EN 21420 and EN 12477.

EN 21420 General Requirements for Protective Gloves
The CE mark, for conformity with European health, safety, and environmental protection standards

This basic standard has to be met by all protective gloves, so all CE marked gloves should meet these requirements.

All products CE marked shall meet requirements such as:

  • Sizing
  • Innocuousness
  • Comfort and efficiency
EN 388 Protective Gloves Against Mechanical Risks

The level of protection achieved in the EN 388 tests are marked on gloves as a series of numbers and letters under a hammer pictogram.

  • A - Abrasion - Level 1 to 4
  • B - Blade - Level 1 to 5
  • C - Tear - Level 1 to 4
  • D - Puncture - Level 1 to 4
  • E - Cut - Level A to F
  • F - Impact - Pass (P) or not marked

  • X - Indicates the test has not been completed
EN 374 Protective Gloves Against Dangerous Chemicals
Shield icon with a conical flask image inside, EN 374-1:2016/Type A written above and U to Z under

In each case, the chemicals tested will be stated under the fuming conical flask pictogram using their code letter, as listed in the official list of test chemicals.

If other chemicals, not present in the list, have also been tested information about the performance levels will be provided in the user instructions.

EN 374 Protective Gloves Against Micro-Organisms
Shield icon with a biohazard image inside, EN 374-5:2016 written above and virus under

The shield with the biological hazard symbol is used to show a glove has passed the penetration test.

If a glove demonstrates protection against blood born pathogens, then this will be shown by stating "virus" underneath.

EN 407 Protection from Thermal Hazards (Heat and/or Fire)
Shield icon with a flame image inside, EN 407:2004 written above and A to F under

The nature and degree of protection is shown by a flame pictogram with the six performance levels of 0 - 4 (lowest to highest), relating to the six different protective qualities underneath.

  • A - Limited Flame Spread - Level 1 to 4
  • B - Contact Heat - Level 1 to 4
  • C - Convective Heat - Level 1 to 4
  • D - Radiant Heat - Level 1 to 4
  • E - Small splashes of molten - Level 1 to 4
  • F - Large quantities of molten - Level 1 to 4

  • X - Indicates the test has not been completed

If LFS is claimed level 1 or above the first shield (flame) is shown, in no LFS is claimed the second shield (heat) is shown

EN 12477 Protective Gloves for Welders

To claim this standard the product must have been testing against EN388, EN407 and EN420/EN21420. The "Type" A or B will be shown underneath the EN407 symbol.

  • Type A - higher heat protection lower dexterity
  • Type B - Lower heat protection higher dexterity
EN 511 Gloves Giving Protection from the Cold
Shield icon with a snowflake image inside, EN 511:2006 written above and A to C under

Protection against cold (down to - 50°C) is illustrated with a snowflake pictogram with the three performance levels, relating to the three protective qualities underneath.

  • A - Convective Cold - Level 1 to 4
  • B - Contact Cold - Level 1 to 4
  • C - Water Impermeability - Level 1 (pass), 0 (fail)
EN 10819 Gloves Giving Protection From Vibrations - Vibration Attenuation
Shield icon with a shaking hand image inside, EN 10819:2013 written above

This standard measures and evaluates the vibration transmissibility of gloves at the palm of the hand, products certified to this standard with show this symbol.

EN 1149 Protective Gloves with Electrostatic Properties
Shield icon with a lightning bolt image inside, EN 1149:2008 written above

Anti-static properties are illustrated with a lightning bolt pictogram. The standard is passed or failed, so no levels are quoted underneath.

EN 421 Protection from Radioactive Contamination
Shield icon with a nuclear image inside, EN 421:2010 written above

Protection against radioactive contamination is illustrated using the nuclear atomic pictogram. The standard is passed or failed so no levels are quoted underneath the pictograms.

EN 421 Protection from Ionising Radiation
Shield icon with a trefoil radioactive image inside, EN 421:2010 written above

Protection against ionising radiation is illustrated using the trefoil radioactive warning symbol, and the lead equivalence must also be marked on the glove. The standard is passed or failed so no levels are quoted underneath the pictograms.

EN 1186 Contact with Food
Icon of a glass and fork standing next to it

The fork and glass symbol is used to show gloves are suitable for use with food.

In many cases, digits under the shield indicate the level of protection for each test within the standard. In general, the higher the number, the higher the level of protection. An X means the glove hasn't been tested for that particular assessment, or that the test is not applicable to that glove.

As well as clearly labelling our gloves, relevant standards feature on our online product pages, throughout our expert guides and in the Arco catalogue.

Which Version of a Standard Do Gloves Comply With?

With introduction of the PPE Regulation (EU) 2016/425, since April 2019, only gloves tested according to the most recent version of standards have been imported into the EU. When stock is depleted you'll need to switch to products tested to the new, most up to date standards.

Changes to EN Standards

Over the past few years, glove standards have undergone several substantial changes. Having been actively involved in driving up quality standards, we welcome the amendments and believe they will result in improved worker safety.

Should I Rely on Standards Alone?

EN standards are an essential guide when selecting hand protection. They help users understand the level of protection gloves are designed to provide. However, products are tested in laboratory conditions, so results don’t always replicate real-life working conditions.

This means standards should only be regarded as advisory in nature. We recommend that you carry out practical trials in your workplace, to assess which gloves perform best in each specific situation.

All PPE gloves you buy from us are CE marked and certified according to the relevant EN standards. We also ensure our gloves continue to meet these standards, but not all suppliers are so rigorous.
