Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests 进行湿砂/橡胶轮磨损试验的标准试验方法
发布日期: 2020-12-01
1.1 本试验方法涵盖了通过湿砂/橡胶轮试验测定金属材料耐刮擦磨损性的实验室程序。本程序的目的是提供数据,在指定的一组条件下,对材料的耐刮擦磨损性进行重复排序。 1.2 磨损试验结果报告为体积损失,单位为立方毫米。耐磨性较高的材料体积损耗较低。 1.3 以国际单位制表示的数值应视为标准值。国际单位制后括号中给出的值仅供参考,不被视为标准值。 1.4 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全、健康和环境实践,并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 任何系统中磨料磨损的严重程度取决于磨料颗粒的大小、形状和硬度、颗粒施加的应力大小以及磨料颗粒的接触频率。在本试验方法中,对这些条件进行了标准化,以形成均匀的磨损条件,即刮伤磨损 ( 1和 2. ). 由于试验方法不试图复制所有工艺条件(磨料尺寸、形状、压力、冲击或腐蚀元素),因此不应使用该方法预测特定环境中给定材料的准确电阻。 该测试方法的价值在于预测材料的排序,其相对优度顺序与研磨环境中的相似。然而,可以将从特定磨料环境中寿命未知的试验材料获得的体积损失数据与从相同环境中寿命已知的材料获得的试验数据进行比较。如果磨损是导致材料劣化的主要因素,则比较将提供未知材料价值的一般指示。
1.1 This test method covers laboratory procedures for determining the resistance of metallic materials to scratching abrasion by means of the wet sand/rubber wheel test. It is the intent of this procedure to provide data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions. 1.2 Abrasion test results are reported as volume loss in cubic millimetres. Materials of higher abrasion resistance will have a lower volume loss. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The severity of abrasive wear in any system will depend upon the abrasive particle size, shape and hardness, the magnitude of the stress imposed by the particle, and the frequency of contact of the abrasive particle. In this test method these conditions are standardized to develop a uniform condition of wear which has been referred to as scratching abrasion ( 1 and 2 ). Since the test method does not attempt to duplicate all of the process conditions (abrasive size, shape, pressure, impact or corrosive elements), it should not be used to predict the exact resistance of a given material in a specific environment. The value of the test method lies in predicting the ranking of materials in a similar relative order of merit as would occur in an abrasive environment. Volume loss data obtained from test materials whose lives are unknown in a specific abrasive environment may, however, be compared with test data obtained from a material whose life is known in the same environment. The comparison will provide a general indication of the worth of the unknown materials if abrasion is the predominant factor causing deterioration of the materials.
