Overview
EN 421:2010 is the CEN (European) standard that specifies requirements and test methods for protective gloves against ionizing radiation and radioactive contamination. It applies to gloves that protect the hand and parts of the arm and shoulder, including gloves intended to be mounted in permanent containment enclosures (gloveboxes) and intermediary sleeves used between a glove and a containment enclosure. The standard explicitly does not cover protective gloves against X‑ray radiation.
Key topics and technical requirements
- Scope and applicability: Defines glove types covered (hand, arm, shoulder protection; containment enclosure gloves; intermediary sleeves).
- Design principles: Gloves may be single- or multi‑layered; materials are chosen by end‑use. For protection from external ionizing radiation, layers may include lead compounds or other heavy elements as attenuation media.
- Attenuation performance: Radiation attenuation is expressed as lead equivalent thickness. EN 421 specifies methods for determining lead equivalence and uniformity of protective material distribution (see test method 5.1).
- Glove integrity: Air‑leak integrity tests are required for containment and glovebox gloves to verify tightness and prevent radioactive contamination spread.
- Mechanical and chemical resistance: Mechanical performance (tear, abrasion, puncture) and chemical resistance requirements reference general glove standards (e.g., EN 388, EN 374).
- Ozone resistance: Static strain ozone cracking tests (ISO 1431‑1) are required where gloves are used in ozone‑containing atmospheres.
- Specific tests and methods: Includes procedures for lead equivalence detection (X‑ray film, numeric film, ionizing chamber), glove integrity (air leak test), ozone cracking, and pull tests for glove–sleeve assemblies.
- Marking and manufacturer information: Specifies required marking, supplied information and labelling; informative annexes cover water‑vapour permeability, warnings, special tests and measurement uncertainty.
- Normative references: Cross‑references key standards such as EN 420, EN 374, EN 388, EN 61331‑1, ISO 11933.
Applications and who uses it
EN 421:2010 is used to specify, design, test, certify and procure gloves for environments with ionizing radiation or radioactive contamination:
- Nuclear and radiological facilities (operations, maintenance)
- Research laboratories handling radioactive materials
- Pharmaceutical and isotope production facilities
- Manufacturers of radiation‑protective gloves, gloveboxes and containment systems
- PPE procurement officers, safety managers, and certification/testing laboratories
- Regulators and conformity assessment bodies assessing compliance with EU directives
Related standards
- EN 420 (general glove requirements)
- EN 374 (chemical/micro‑organism resistance)
- EN 388 (mechanical risks)
- EN 61331‑1 (attenuation properties for X‑radiation - referenced for methods)
- ISO 11933 (components for containment enclosures)
- ISO 1431‑1 (ozone resistance)
EN 421:2010 provides a practical framework for ensuring glove performance against radioactive contamination and ionizing radiation while aligning with broader PPE and containment component standards.

4.2 Design principles 4.2.1 General principles The glove shall comply with the relevant requirements defined in EN 420, with the following specific additions. The glove may be constructed from a single or multiple material layers. The choice of material is defined by the end use requirements. In the case of protection against external ionizing radiation the glove may contain lead (PbO, Pb3O4) or other heavy metallic elements to act as attenuation medium in one or more of the layers. Metallic element distribution may be uniform or designed. 4.2.2 Glove sizing and dimensions Gloves shall be sized following prescriptions of EN 420:2003+A1:2009, 5.1. NOTE In case where specific use identified, special tests can be identified according to Annex B. 4.3 Attenuation efficiency and uniformity of distribution of protective material The lead equivalent thickness shall be measured by one of the methods described in 5.1. The test methods give equivalent results. The efficiency of the glove material to absorb radiation is quoted as lead equivalent thickness. The gloves shall have at least a lead equivalence thickness of 0,05 mm. SIST EN 421:2010
ISO 11933-2 shall be followed. Gloves used in containment enclosures are often used with under gloves. The user will have to take into account this parameter for the choice of an adapted size of equipment. NOTE ISO 11933-1 and ISO 11933-2 detail a list of characteristics of standardized gloves, glove ports, support rings, cell rings, etc. 4.7.2.3 Accessories used with gloves 4.7.2.3.1 Gloves equipped with a support ring In a few permanent containment enclosures, gloves can be equipped with a support ring. The support ring is considered as an integral part of the glove, and the whole equipment shall be tested according to the air leak test using a test bench equipped with a cell ring (see 4.7.3). 4.7.2.3.2 Sleeve Gloves mounted in permanent containment enclosures can be used with an intermediary sleeve, fixed between the glove and the containment enclosure. This sleeve is not considered as an integral part of the glove. It shall fulfill all requirements of this European Standard and shall be compatible with the glove used. The way of fixation between the glove and the sleeve and between the sleeve and the containment enclosure shall be detailed in the information supplied by the manufacturers. The sleeve shall be tested with one compatible glove as regards the integrity using the air leak test (see 4.7.3) Such an assemblage shall resist to a tensile strength test of 100 N according to 5.4. 4.7.3 Specific integrity test for gloves for containment enclosures The integrity of gloves used in containment enclosures shall be tested by the air leak test described in 5.2. The pressure shall not decrease by more than half the initial pressure. The initial pressure shall be mentioned in the instructions supplied by the manufacturer if it is different from 3 000 Pa. 4.7.4 Resistance to ozone cracking (static strain) When gloves can be exposed to ozone, the resistance to ozone cracking shall be determined. NOTE Powders emitting alpha particles can generate ozone containment enclosures. The performance level shall be determined by the method described in 5.3; at least level 1 of Table 2 shall be achieved. SIST EN 421:2010
