标准范围

规定了测定维氏硬度的试验方法（当测试直径大于0.5mm的颗粒时，使用9807 N的试验力，即HV 1，当测试直径为0.3mm至0.5mm的颗粒时，使用4904 N的试验力，即HV 0.5）。对于0.3 mm以下的颗粒，不建议使用该方法进行测试。目的是确定金属磨料的坚固性。明显的内部收缩或空心颗粒会降低表观密度。附录A给出了金属喷砂清理磨料ISO 11124和ISO 11125的国际标准系列信息。

Specifies a test method for the determination of the Vickers hardness (using a test force of 9,807 N, i.e. HV 1, when testing particles with a diameter greater than 0,5 mm, and a test force of 4,904 N, i.e. HV 0,5, when testing particles with a diameter of 0,3 mm to 0,5 mm). The method is not recommended for the testing of particle sizes below 0,3 mm. The purpose is to establish the soundness of the metallic abrasive. Significant levels of internal shrinkage or hollow particles will reduce the apparent density. Annex A gives information on the international standards series for metallic blast-cleaning abrasives ISO 11124 and ISO 11125.
