This standard should not be used alone, but only in combination

26、with the appropriate specific standard. DIN EN 420:2010-03 EN 420:2003+A1:2009 (E) 5 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, marki

27、ng 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

28、 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 The following referenced documents are indispensable for the application of this document.

38、e corresponding test as described in the specific standards referred to in the Bibliography. A high level number corresponds to a high level of performance. Levels of performance are based upon the results of laboratory tests, which do not necessarily reflect actual conditions in the workplace. 4 Ge

39、neral 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

40、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 relevan

41、t, 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

42、 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 cor

43、relation between results obtained through these different test methods. NOTE 2 These tests are not suitable to classify these gloves as waterproof.

Glove materials, degradation produ

45、cts, incorporated substances, seams and edges and particularly those parts of the glove in close contact with the user shall not adversely affect the users health and hygiene. The manufacturer or his authorized representative shall name all the substances contained in the glove which are known to ca

46、use allergies (see 7.3.8). 4.3.2 Determination of pH Value The pH value for all gloves shall be greater than 3,5 and less than 9,5. Determination of pH shall be according to EN ISO 4045 for leather gloves, and EN 1413 for other materials. Following amendments shall apply: the test piece shall be cut

47、 out from the palm area of the glove. If other parts of the glove are made of different materials, then each material shall be tested separately; if gloves are made of more than one layer, all layers shall be tested together; if the sample contains leather, then EN ISO 4045 shall be used; subclause

48、8.4 of EN ISO 4045:1998 does not apply. 4.3.3 !Determination of chromium VI content The quantity of Chromium VI in gloves containing leather shall not exceed 3,0 mg/kg when determined according to the test method described in EN ISO 17075:2007. Depending on the measured Chromium VI content, the test

49、 report shall indicate: that the Chromium VI content is not in excess of 3,0 mg/kg, or that Chromium VI content is in excess of 3,0 mg/kg and the value that has been determined in mg/kg. If the glove includes different types of leather, whether in contact with the skin or not, each leather type shall be tested separately and comply with the above requirement. At least two samples sh
