STANDARD EN 421:1994

PROTECTION AGAINST IONIZING RADIATION AND RADIOACTIVE CONTAMINATION

Scope:

This standard indicates that a glove provides protection from ionizing radiation and radioactive contamination.

TERM DEFINITIONS

The type of protection that a glove provides is indicated by a pictogram related to the specific protective qualities.

Protection from Radioactive

Contamination requires that the glove be liquid-proof and able to pass the penetration test as laid out in EN 374.
Gloves used in containment enclosures must also pass a specific air pressure leak test.

Protection from Ionizing Radiation

Requires that the glove contains a certain quantity of lead (or lead equivalence) that is marked on each glove.
Any material exposed to ionizing radiation may be modeled by its behaviour to ozone cracking. This is an optional test that may be used as an aid in selecting gloves that require ionizing radiation resistance.
