BS EN 420:2003 pdf free download.Protective gloves – General requirements and test methods.
Introduction
This European Standard is a reference standard to be called up as appropriate by the specific European Standards relevant or applicable to protective gloves.
This standard should not be used alone, but only in combination with the appropriate specific standard.
1 Scope
This standard defines the general requirements and relevant test procedures for glove design and construction, resistance of glove materials to water penetration, innocuousness, comfort and efficiency, marking and information supplied by the manufacturer applicable to all protective gloves.
NOTE It can also be applicable to arm protectors and gloves permanently incorporated in containment enclosures.
This European Standard does not address the protective properties of gloves and therefore should not be used alone but only in combination with the appropriate specific European Standard(s).
A non exhaustive list of these standards is given in the Bibliography.
2 Normative references
This European standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

4 General requirements
4.1 Glove design and construction — General
The protective glove shall be designed and manufactured so that in the foreseeable conditions of use for which it is intended, the user can perform the hazard related activity normally whilst enjoying appropriate protection at the highest possible level.
If required, the glove shall be designed to minimize the time needed for putting on and taking off.
When the glove construction includes seams, the material and strength of the seams shall be such that the overall performance of the glove is not significantly decreased. Where relevant, test methods and requirements are specified in the specific standards listed in the Bibliography.
4.2 Resistance of glove materials to water penetration
For glove materials where resistance to water penetration is required (according to the intended use of the glove), the appropriate test methods shall be used:
— For leather gloves: 5.12 of EN 344-1:1992. The results shall be reported according to Table 1;
— Alternative test method which is more appropriate to textile materials: EN 20811. The results shall be reported as a pressure in Pascal as required in EN 20811.
NOTE 1 There is no known correlation between results obtained through these different test methods.
