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) . 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 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和健康实践，并确定监管限制的适用性。

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) . Actual erosion service involves particle sizes, velocities, attack angles, environments, etc., 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 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 and health practices and determine the applicability of regulatory limitations prior to use.
