1.1 这些试验方法包括使用卡尼漏斗测定不易通过试验方法霍尔漏斗的金属粉末和粉末混合物的流速 2013年2月 . 1.2 这是在实验室进行的非破坏性定量测试。 1.3 除用于确定密度的密度和质量值外，使用克每立方厘米（g/cm） 3. )而克（g）单位是长期的行业惯例，以英寸-磅为单位的数值将被视为标准。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准值。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 模具型腔填充的速度和均匀性与流动财产有关，从而影响生产速度和压实零件的均匀性。 5.2 粉末的流动能力是颗粒间摩擦的函数。随着颗粒间摩擦的增加，流动速度减慢。一些粉末，通常是细粉末和润滑粉末混合物，可能不会流过试验方法的霍尔漏斗 2013年2月 然而，如果提供更大的孔口，例如在卡尼漏斗中，可以确定有意义的流速，从而为某些应用提供特定信息。 5.3 试验方法 2013年2月 使用霍尔漏斗是测定金属粉末流动性的优选方法。只有当粉末不会流过霍尔漏斗时，才应使用这些测试方法的卡尼漏斗。当一些粉末流过霍尔漏斗而一些没有流过霍尔漏斗时，这些测试方法也可用于几种粉末的比较。 5.4 湿度和含水量影响流速。潮湿或潮湿的粉末可能不会流过霍尔或卡尼漏斗。 5.5 这些测试方法基于特定质量粉末的流量。如果优选特定体积的粉末流动，试验方法 B855型 可用于容易流过霍尔漏斗的粉末。 5.6 这些测试方法可能是粉末供应商和粉末冶金（PM）零件制造商之间采购协议的一部分，也可能是供应商或最终用户的内部质量控制测试。

1.1 These test methods cover the determination of a flow rate, by use of the Carney funnel, of metal powders and powder mixtures that do not readily flow through the Hall funnel of Test Method B213 . 1.2 This is a non-destructive quantitative test performed in the laboratory. 1.3 With the exception of the values for density and the mass used to determine density, for which the use of gram per cubic centimetre (g/cm 3 ) and gram (g) units is the longstanding industry practice, the values in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that 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 rate and uniformity of die cavity filling are related to flow properties, which thus influence production rates and uniformity of compacted parts. 5.2 The ability of a powder to flow is a function of interparticle friction. As interparticle friction increases, flow is slowed. Some powders, often fine powders and lubricated powder mixtures, may not flow through the Hall funnel of Test Method B213 . Nevertheless, if a larger orifice is provided, such as in the Carney funnel, a meaningful flow rate may be determined, providing specific information for certain applications. 5.3 Test Method B213 , using the Hall funnel, is the preferred method for determining the flowability of metal powders. The Carney funnel of these test methods should only be used when a powder will not flow through the Hall funnel. These test methods may also be used for comparison of several powders when some flow through the Hall funnel and some do not. 5.4 Humidity and moisture content influence flow rate. Wet or moist powders may not flow through either the Hall or the Carney funnel. 5.5 These test methods are based on flow of a specific mass of powder. If flow of a specific volume of powder is preferred, Test Method B855 may be used for powders that flow readily through the Hall funnel. 5.6 These test methods may be part of the purchase agreement between powder suppliers and powder metallurgy (PM) part producers, or it can be an internal quality control test by either the supplier or the end user.
