标准摘要
[中文适用范围]: 摘自:ISO 3923-2:1981 ISO 3923 的本部分规定了斯科特体积法,用于测定金属粉末的表观密度。它适用于不会自由流过 5 毫米孔的粉末(参见 ISO 3923/1)。本国际标准的第 3 部分规定了振荡漏斗法,用于测定此类粉末的表观密度,这是首选方法,因为它可以提供更好的精度,但在粉末可能因测试期间对粉末施加的振动作用而改变其特性的情况下不能使用该方法。 [外文原描述]: IS applicable to powders that will not flow freely through a 5 mm orifice. The oscillating funnel method (part 3) gives better precision, but it cannot be used in cases where the powder may change its properties due to the vibration action applied to the powder during testing. Gives principle, symbols and designations, apparatus, sampling, procedure, expression of results and test report.
英文名称Metallic powders — Determination of apparent density — Part 2: Scott volumeter method
