防护服.防止被手持刀具割伤和刺伤用的手套和手臂保护物.第3部分:编织物,皮革和其它编织材料的冲击切割试验

[中文适用范围]： ISO 13999 的这一部分规定了用于防护服、手套和护臂中使用的织物、皮革和其他材料的冲击切割测试。 ISO 13999 本部分的附录 A 给出了有关手套和护臂等材料和产品的冲击切割测试规范的建议，并给出了产品标准中应指定的信息列表，以便能够应用该测试。 [外文原描述]： This part of ISO 13999 specifies an impact cut test for use on fabric, leather and other materials used in protective clothing materials, gloves and arm guards. This test assesses the resistance of the test specimen to cutting by a sharp, straight knife-edge after the point of the test knife has perforated the test specimen. The length of the cut produced by the particular impact energy is proportional to the depth of penetration of the knife, which is easily measured. This test method provides information about the resistance of the product to stabbing cuts, slashing cuts, shearing cuts and impact cuts by acute edged objects that are not necessarily sharp. Abrasion by coarse sharp abraders such as road surfaces, concrete building blocks, or rough metal castings, is the superimposition of numerous small cuts. The results from this test give a good prediction of the resistance of products to these types of harsh abrasion. This test does not provide information about the resistance of the product to penetration by thorns or needles. Annex A of this part of ISO 13999 gives recommendations for the specification of impact cut tests on materials and products such as gloves and arm guards and gives the list of information which should be specified in the product standard in order to be able to apply this test.
