1.1 本试验方法包括使用Barcol压痕机测定铝合金的压痕硬度。 1.2 以国际单位制表示的数值应视为标准。国际单位制后括号中给出的值仅供参考，不被视为标准值。 1.2.1、 一些Barcol压痕器用于塑料，不包括在本试验方法中，不应用于铝合金。 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）。本标准的使用者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》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 Barcol压痕机是便携式的，因此可用于生产控制目的的制造零件和单个试样硬度的现场测定。 4.2 该试验方法只能在适用材料规范中引用时使用。

1.1 This test method covers the determination of indentation hardness of aluminum alloys using a Barcol Impressor. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.2.1 Some Barcol Impressors are for use on plastics and are not included in this test method and should not be used for aluminum alloys. 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 ====== 4.1 The Barcol Impressor is portable and therefore useful for in situ determination of the hardness of fabricated parts and individual test specimens for production control purposes. 4.2 This test method should be used only as cited in applicable material specifications.
