BS 421:2010 pdf download – Protective gloves against ionizing radiation and radioactive contamination The lead equivalent thickness shall always be linked with the nature and energy of the radiation used duringtests (see Clauses 6 and 7). 4.4 Glove integrity The purpose of the glove to protect against ionizing radiation or radioactive contamination is to isolate the userfrom the potential hazard.This is only possible if the integrity of the glove is proven. Gloves shall pass an integrity test: the integrity shall comply with the requirements of EN 374-1:2003,5.2. 4.5 Mechanical requirements For each protective glove against radioactive contamination and/or ionizing radiation,the obtainedperformance level shall be indicated in the information supplied by the manufacturer for the followingmechanical tests: -abrasion resistance; —blade cut resistance; -tearing resistance; -puncture resistance. According to the test methods described in EN 388:2003, at least level 1 shall be reached for one of the fourmechanical properties. For special purposes, dexterity is the most important parameter, in this case no level ofprotection of EN 388 has to be reached, but the following sentence shall be written in the user notice of thegloves: “This gloves does not protect against mechanical risks.” 4.6 Chemical requirements lf required, the chemicals properties of the gloves shall be determined following the requirements defined inEN 374-1;2003,5.3.1.The test method for permeation is described in EN 374-3. Two possibilities are acceptable: The glove fulfills EN 374-1:2003,5.3.2; In this case the pictogram of EN 374-1:2003, Figure 1 shall beused. The chemicals to be tested are defined taking into account the use of the glove at the work place. Iin thiscase the pictogram of EN 374-1:2003,Figure 2 shall be used. 4.7 Specific requirements for gloves for containment enclosures 4.7.1General requirement for gloves for containment enclosuresGloves for containment enclosures shall comply with 4.1,4.2,4.3 and 4.4.NOTE Annex A provides an optional test method for water vapour permeability. 4.7.2Design for gloves for containment enclosures4.7.2.1General The glove shall comply with the relevant requirements defined in ISO 11933-2. When the metallic element distribution is not uniform over the glove,the manufacturer shal mark theequipment and provide the information accordingly (see Clauses 6 and 7). 4.7.2.2Glove sizing and dimensions In the case of gloves to be mounted in containment enclosures,prescriptions of lSo 11933-1 andISO 11933-2 shall be followed. Gloves used in containment enclosures are often used with under gloves. The user will have to take intoaccount this parameter for the choice of an adapted size of equipment....
