EN 420: The Standard In Glove Safety

Monday, 10 August 2015  |  Admin

If you've used work gloves in the past then you'll have heard of EN 420 before. If you're new to work gloves, then you might be a little confused about what it means, as even the most experienced safety gloves user struggles to understand exactly what EN 420 is. It's possible that we get more questions about EN 420 than anything else, so if you fit that category take a look at our guide below.

Unfortunately, there's quite a lot to EN 420. So, we've separated this article out into different sections which you can view by clicking on the anchors below:

Back to Basics: What Is EN 420?

EN 420 is the hallmark of any decent safety glove. It's the basic standard, something that a disposable glove in the medical industry will be certified to in the same way as a cut 5 glove for manufacturing glass or a heat resistant glove for soldering. EN 420 covers both Disposable Single Use Gloves and Reusable Gloves.

The point in EN 420 is that it proves that the gloves will not be a harm to the user and that the gloves are comfortable to wear, something that when passed, will allow the gloves to be tested to EN 388, EN 374, EN 455 and other glove standards. EN 420 covers quite a bit of scope, with the main areas coming under:

  • Innocuousness
  • Anti-static and Water Vapour
  • Packaging and Instructions
  • Symbols/Information on the Glove

The Specifications: How Will a Glove Meet EN 420?


The first test is innocuousness, which ensures that the gloves will be comfortable, will fit, and will not damage the wearer.

  • Glove Length and Glove Size:

    • The length of a glove is measured by suspending it from the middle finger and by placing a ruler inside the glove to remove any creases. The glove is then fitted onto a model hand that has the same dimensions as those that the glove is intended to fit, the purpose being to ensure that all gloves have a standardised size. Measurements can be found below:

Standardised Glove Size (mm)

Hands Size Palm Circumference Hand Length
Size 6 (Extra Small) 152mm 160mm
Size 7 (Small) 178mm 171mm
Size 8 (Medium) 203mm 182mm
Size 9 (Large 229mm 192mm
Size 10 (Extra Large) 254mm 204mm
Size 11 (XX-Large) 279mm 215mm

Standardised Glove Length (mm)

Size Minimum Glove Length
Size 6 (Extra Small) 220mm
Size 7 (Small) 230mm
Size 8 (Medium) 240mm
Size 9 (Large) 250mm
Size 10 (Extra Large) 260mm
Size 11 (XX-Large) 270mm
  • Dexterity:
    • A wearer will be required to pick up five pins with a diameter of between 5mm and 11mm. The smaller an item can be picked up, the higher dexterity the gloves will achieve.
  • pH Value:
    • A pH value will be determined to ensure safety in the hand. The pH value should be less than 9.5 but greater than 3.5.
  • Chrome VI:
    • The gloves must also not include dangerous metals such that can cause allergic reactions such as chromium.
    • Chromium (VI) Content should be below detection (< 3mg/kg).
  • Other Points:
    • Gloves must offer the greatest possible degree of protection
    • If the glove features seams, they should not reduce the performance of the glove
    • Natural rubber gloves should be tested on extractable proteins to ensure they do not cause allergic reactions in the wearer
    • If cleaning instructions are provided, the level of performance must not be reduced even after the maximum number of washes

Electrostatic and Water Vapour

If a glove is electrostatic or resistant to water vapour, then the gloves must undergo further testing.

  • Electrostatic Gloves:
    • Anti-Static Gloves shall be placed through electrostatic tests, the results of which will be reported within the instructions.
    • An electrostatic pictogram should not be used.
  • Water Vapour:
    • If required, gloves shall allow water vapour transmission (5mg/cm2)
    • If gloves exclude water vapour transmission, it should be at least 8mg/cm2 for 8 hours
    • If  required, gloves shall allow water vapour transmission (5mg/cm2)

Packaging and Instructions

On either the packaging or instructions, you can expect to find certain information. This will include:

  • The name of the manufacturer
  • Glove sizes
  • Appropriate pictograms to display EN standards and levels (these markings must remain clear through the life of the glove)
  • Address of the manufacturer or representative
  • It's intended application (e.g. for minimal risks only)
  • If the protection is specific to a certain area (e.g. palm area only)
  • Care and storage instructions
  • A list of substances that are known to cause allergies and the name and address of the body that certified the product.


Finally, all gloves that have been certified to EN 420 must include the EN 420 symbol. This will be on the back of the gloves and on the packaging. The symbol can be identified below:

The main point to remember is that all EN 420 gloves must meet the above standards for it to be tested to heat, cold, cut and more.
