1.1 本规范涵盖了实践中引用的工业标准物质（IRM）的生物质量规范或要求，或两者兼有 D4678 以及其他标准。 1.2 《实践》中评估和参考的IRM D4678 ，对橡胶和炭黑行业的产品、规格和开发测试至关重要。 1.3 在接受新批次材料作为IRM之前，它必须符合本规范中规定的规范。但是，这些规范只是要求的一部分。 实践中给出的其他要求 D4678 应在候选材料被正式接受为生物IRM之前满足要求。 1.4 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.5 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。 1.6 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。

1.1 This specification covers the biological quality specifications or requirements, or both, for Industry Reference Materials (IRMs) as cited in Practice D4678 and other standards. 1.2 IRMs, as evaluated and referenced in Practice D4678 , are vitally important to conduct product, specification, and development testing in the rubber and carbon black industries. 1.3 Before a new lot of material can be accepted as an IRM, it must comply with the specifications prescribed in this specification. However, these specifications are only part of the requirements. Other requirements as given in Practice D4678 shall be met before a candidate material can be formally accepted as a biological IRM. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. 1.6 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.
