This applies to test methods described in 6.4, 6.5, 6.6, 6.7, and 6.8. 6.1 Abrasion Test according to EN 388. 6.2 Tear resistance Test according to EN 388. 6.3 Burn

39、ing behaviour Test method is that given in ISO 6941 with the following modifications. The burner is lighted and preheated for 2 min. The perpendicular flame height is adjusted to (40 2) mm, the distance being measured between the burner tip and the yellow flame tip. The flame is viewed in a dim ligh

The distance between the tip of the burner and the lower edge of the glove or the middle finger must be 20 mm. One glove is tes

43、ted for each ignition time, i.e. for 3 s and 15 s. The after flame time and after glow time are recorded for each ignition time (see Table 1). Moreover the material, if it melts, shall not drip and the seam shall not come apart in the burn test area. 6.4 Contact heat Test method according to prEN 70

44、2. From each palm area of three gloves one sample is taken with a diameter of 80 mm. From the three single values for the threshold time tt the arithmetic mean is calculated and stated to the nearest whole second. 6.5 Convective heat The test method is that given in EN 367 with the following modific

45、ations. The size of the test specimen shall be 140 mm 140 mm. If it is not possible to take such a specimen from a glove then a material sample should be used, provided it was produced in the same way as the glove.

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

47、the nearest whole second. 6.6 Radiant heat The test method is that given in EN 366:1993, method B, with the following modifications. From the back of the glove of a pair of gloves, two specimens of 70 mm 170 mm are taken. Heat flux density qo = 20 kW/m2 In the case of multilayered gloves the test is

48、 carried out simultaneously on all layers. Heat transfer level 3 is determined which is characterized by the time t3 taken for the heat transmitted through the specimen to reach a level of 2.5 kW/m2. The arithmetic mean of the two single values is calculated and expressed to the nearest second. 6.7

49、Small drops of molten metal Test method according to EN 348. The test is carried out on four specimens. Specimens are taken from each palm and back of pair of gloves. The specimen size is 120 mm 20 mm. From these single values the arithmetic mean is calculated and stated to the nearest whole number of drops. 6.8 Large quantities of molten metal The test method is that given in EN 373 with the following modifications. The test is carried out with each three specim
