EN 407:2004 (E) 4 1 Scope This document specifies requirements, test methods, information to be suppli
20、ed and marking for protective gloves against heat and/or fire. It should be used for all gloves which protect the hands against heat and/or flames in one or more of the following forms: fire, contact heat, convective heat, radiant heat, small splashes or large quantities of molten metal. This standa
21、rd is only applicable in conjunction with EN420. There are other standards relevant to specific applications, as for example fire-fighting or welding. Product tests may only give performance levels and not protection levels. 2 Normative references The following referenced documents are indispensable

This test only applies to molte

The corresponding test results shall be given on the information supplied by the manufacturer (clause 8). 6 Test methods For multilayered gloves, the tests are carried out simultaneously on all layers, even if these in some circumstances are no longe
42、r connected. This applies to test methods described in 6.3, 6.4, 6.5, 6.6, 6.7, and 6.8. 6.1 Abrasion Test according to EN 388. EN 407:2004 (E) 9 6.2 Tear resistance Test according to EN 388. 6.3 Burning behaviour Test method according to EN ISO 6941 with the following modification: the glove is mou
43、nted vertically so that the point A (Figure 1) is at the mid point of the lower edge. Figure 1 Mounting of test glove The burner is placed below the glove so that it is in a plane with the vertical middle line of the glove or the middle finger and is perpendicular to the surface of the glove. The bu
44、rner is mounted at an angle of 30 3 to the vertical. The distance between the tip of the burner and the lower edge of the glove or the middle finger shall be 20 mm 2 mm. One glove shall be tested for each ignition time, i. e. for 3 s and 15 s. The after flame time and after glow time shall be record
45、ed for each ignition time (see Table 1). 6.4 Contact heat Test method according to EN 702. From each palm area of three gloves one sample shall be taken with a diameter of 80 mm 8 mm. If a reinforcement is added to the palm of the gloves, then the samples taken shall be without reinforcement. The ma
46、nufacturer may additionally report test results from the parts of the glove with reinforcement in the information in clause 8. However, it shall be checked that the reinforcement is made of a material that does not melt at the test temperature. From the three single values for the threshold time t t
47、the arithmetic mean shall be calculated and stated to the nearest whole second. EN 407:2004 (E) 10 6.5 Convective heat The test method is according to EN 367 with the following modifications: The size of the test specimen shall be (140 5) mm (140 5) mm. If it is not possible to take such a specimen
48、from a glove then a material sample shall be used, provided it was produced in the same way as the glove and includes any seam present. The specimens shall be taken from or representative of the palm and the back of the glove. Samples of multilayered assemblies shall correspond to the usual order of the layers. For each material type or material assembly, three specimens shall be tested. The arithmetic mean is calculated from the three single values and stated to the nearest whole second. 6.6 Radiant heat Th
