1.1 本试验方法包括使用jetnozzle型侵蚀设备测定气体夹带固体颗粒冲击侵蚀的材料损失。该试验方法可在实验室中用于测量不同材料的固体颗粒侵蚀，并已被用作筛选试验，用于对模拟服务环境中材料的固体颗粒侵蚀率进行排序 ( 1. , 2. ) . 2. 实际侵蚀服务涉及颗粒大小、速度、攻角、环境等，这些将在很大范围内变化 ( 3- 5. ) . 因此，任何单一的实验室测试可能不足以评估预期的使用性能。本试验方法描述了一种具有良好特征的固体颗粒冲击侵蚀测量程序，可获得实验室间试验结果。 1.2 单位- 以国际单位制表示的数值应视为标准值。 本标准不包括其他计量单位（以下例外情况）。 1.2.1 例外情况: 表1 使用HRB硬度。脚注7和 11.2 使用磨料名称。 1.3 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。 1.4 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. 该测试方法在评估材料侵蚀行为的任何整体测量程序中的重要性将取决于与服务应用条件有关的许多因素。该测试方法的用户应确定获得的结果与现场性能或使用其他测试系统和方法的结果的相关性程度。本试验方法可用于在规定的试验条件下对材料的抗侵蚀性进行排名。

1.1 This test method covers the determination of material loss by gas-entrained solid particle impingement erosion with jetnozzle type erosion equipment. This test method may be used in the laboratory to measure the solid particle erosion of different materials and has been used as a screening test for ranking solid particle erosion rates of materials in simulated service environments ( 1 , 2 ) . 2 Actual erosion service involves particle sizes, velocities, attack angles, environments, and so forth, that will vary over a wide range ( 3- 5 ) . Hence, any single laboratory test may not be sufficient to evaluate expected service performance. This test method describes one well characterized procedure for solid particle impingement erosion measurement for which interlaboratory test results are available. 1.2 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard (exceptions below). 1.2.1 Exceptions: Table 1 uses HRB hardness. Footnote 7 and 11.2 use abrasive grit designations. 1.3 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. 1.4 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 significance of this test method in any overall measurements program to assess the erosion behavior of materials will depend on many factors concerning the conditions of service applications. The users of this test method should determine the degree of correlation of the results obtained with those from field performance or results using other test systems and methods. This test method may be used to rank the erosion resistance of materials under the specified conditions of testing.
