EN ISO 21420 is applicable and required for all PPE gloves. It defines the general rules for comfort, innocuousness, marking, packaging and user notice.
The EN ISO 21420 will replace the EN 420:2003 + 1:2009 when EN ISO 21420 will be published in the Official Journal of the European Union. From a standardization point of view and for the CEN, EN 420 will be deleted after September 30th, 2020.
Therefore, we highly recommend you to apply EN ISO 21420:2020 for all your coming certification requests.
This new revision does not imply to revise the existing certificates which remain valid until their date of expiry.
It is the responsibility of the manufacturers to ensure their PPE remain in conformity with the state of art. Therefore, the manufacturer has to verify independently whether their productions stay in conformity with the applicable requirements, as for example REACh requirements.
The new EN ISO 21420 is clearer and more explicit than the previous EN 420. The list of substances to check is now given:
For reusable multilayer gloves, when the wearer takes off the glove, the lining must not come out of the glove.
No more minimum glove lengths requirement except if a minimum length is required by the specific use standard (welders, firefighters…)
Note: the test method is new.
EN ISO 21420 recommend the same hand sizing system as before. The new is that you can now use your own hand sizing system. In this case, hand circumference and hand length by size shall be detailed in the user instructions and the technical file.
Note: hand sizing system is different than glove length.
There is a change in the test method, the cylinder must be held at the fingertips for 5 seconds before releasing it. It is not a big change but it can be very important for certain gloves where dexterity is critical (welding for example). Dexterity becomes mandatory when the specific application standard requires it.
How to deal with cleaning is more clearly written. If care instructions are provided, the tests shall be done before cleaning and after cleaning. The results retained are the worst ones.
New pictograms are available in annex C :
Manufacturing date (or any mean ensuring the manufacturing batch traceability)
if applicable, Obsolescence date in addition to the manufacturing date
Protection against static electricity (EN 16350)
Protection against heat without flame
To the requirements already known with the old EN 420, the new revision adds:
Ask your usual contact at CTC CE marking team. He will provide you a simple and easy form to fulfil.
