24、 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 conta

25、inment 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).

32、. Key a Hand b Back c Palm Figure 1 Definitions of hand, palm and back 3.1 hand part of the body from the tip of the middle finger to the wrist 3.2 glove personal protective equipment (PPE) which protects the hand or part of the hand against hazards. It can additionally cover part of the forearm and

33、 arm 3.3 glove palm part of the glove which covers the palm of the hand, i.e. from the wrist to the base of the fingers 3.4 glove back part of the glove which covers the back of the hand (i.e. from the wrist to the base of the fingers) 3.5 dexterity manipulative ability to perform a task 3.6 hazard

34、situation which can be the cause of any harm or damage to the health of the human body. A non exhaustive list of specific standards dealing with hazards is given in the Bibliography BS EN 420:2003+A1:2009EN 420:2003+A1:2009 (E) 7 3.7 level of performance number that designates a particular category

35、or range of performance by which the results of testing can be graded The level of performance is determined by the result of the 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 perfo

36、rmance are based upon the results of laboratory tests, which do not necessarily reflect actual conditions in the workplace. 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

37、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

38、 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 materi

39、als 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

40、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. NOTE 2 These tests are not suitable to classify these gloves as waterproof.

42、vide protection when used according to the manufacturers instructions, without harm to the user. Glove materials, degradation products, 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 hy

43、giene. The manufacturer or his authorized representative shall name all the substances contained in the glove which are known to cause 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 accordin

44、g to EN ISO 4045 for leather gloves, and EN 1413 for other materials. Following amendments shall apply: the test piece shall be cut 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 m

45、ore than one layer, all layers shall be tested together; if the sample contains leather, then EN ISO 4045 shall be used; subclause 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 w

46、hen determined according to the test method described in EN ISO 17075:2007. Depending on the measured Chromium VI content, the test 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 det

47、ermined 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 shall be taken from different gloves for each leather type.“ 4.3.4 Determination of ex

48、tractable protein content Natural rubber gloves shall be submitted to requirements stated in EN 455-3 on extractable protein content. NOTE This method has not yet been validated for gloves other than medical gloves for single use. 4.4 Cleaning All tests required in this standard as well as in the st

49、andards for protective gloves shall be performed on unused gloves unless otherwise specified. If care instructions are provided (see 7.3.10), the relevant tests of the specific standards (see Bibliography) shall be performed on the gloves, before and after they have been subjected to the maximum recommended number of cleaning cycles.
