1.1 本规程描述了用于热分析或流变仪测量的仪器的一般描述，其目的是在整个标准试验方法中实现热分析、流变仪和粘度计仪器描述的一致性。这些描述旨在用作模板，以包含在引用本文所述热分析仪器的任何测试方法中。 1.2 每种描述都包含为每种测试方法规定的可量化仪器性能要求。 1.3 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户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。 1.5 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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 部分 5. 确定对各种不同仪器进行热分析、流变仪或粘度测定所需的基本仪器和附件。描述本文所述热分析、流变仪或粘度计仪器的使用或应用的任何测试方法中应包括适当的通用仪器说明。 4.2 这些描述中包含的单元用于确定所需的性能标准，被视为典型。当在特定试验方法中包括这些描述时，可以使用其他单位。下划线项目构成为每种测试方法专门制定的所需输入（例如，温度传感器的灵敏度）。 4.3 可根据需要添加额外的部件和附件，并规定适当的性能要求。这些说明中列出但未在试验方法中使用的项目（例如，真空系统）可以删除。

1.1 This practice describes generic descriptions of apparatus used for thermal analysis or rheometry measurements and its purpose is to achieve uniformity in description of thermal analysis, rheometry, and viscometer instrumentation throughout standard test methods. These descriptions are intended to be used as templates for inclusion in any test method where the thermal analysis instrumentation described herein is cited. 1.2 Each description contains quantifiable instrument performance requirements to be specified for each test method. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 ====== 4.1 Section 5 identifies essential instrumentation and accessories required to perform thermal analysis, rheometry, or viscometry for a variety of different instruments. The appropriate generic instrument description should be included in any test method describing use or application of the thermal analysis, rheometry, or viscometry instrumentation described herein. 4.2 Units included in these descriptions are used to identify needed performance criteria and are considered typical. Other units may be used when including these descriptions in a specific test method. Items underlined constitute required inputs specifically established for each test method (for example, sensitivity of temperature sensor). 4.3 Additional components and accessories may be added as needed, with the appropriate performance requirements specified. Items listed in these descriptions but not used in a test method (for example, vacuum system) may be deleted.
