1.1 本标准描述了包括E、J、K、N和T型在内的基底金属热电偶连接器的热电动势测试方法。标准连接器，如规范中所述 E1129/E1129M 和 E1684/E1684米 以及非标准连接器配置和连接器组件都可以使用该方法进行评估。 1.2 测量的电动势被报告为相对于相同类型的参考热电偶的等效温度偏差或误差。此方法可用于验证连接器引入的偏差大于或等于1 °C。 1.3 使用指定的热边界条件，使用与温度梯度轴向对准的热电偶触点对连接器进行测试。连接器上产生的实际温差和相应的误差将取决于连接器的设计。 1.4 连接器触点通常由具有符合规范的温度emf关系的原材料制成 E230/E230M 。但是，验证规范 E230/E230M 公差不在此方法的范围内。 1.5 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。 1.6 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。 1.7 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====== 5.1 暴露在温差下的热电偶连接器有助于热电偶电路的输出。分配给连接器的输出不确定性取决于连接器的设计和温度梯度。 5.2 连接器性能可以根据此方法的结果进行分类，并用作组件规范的一部分。 5.3 该方法可作为工程工具，用于评估在相似热条件下测试的不同连接器设计。

1.1 This standard describes a thermal emf test method for base-metal thermocouple connectors including Types E, J, K, N, and T. Standard connectors such as found in Specifications E1129/E1129M and E1684/E1684M as well as non-standard connector configurations and connector components can be evaluated using this method. 1.2 The measured emf is reported as an equivalent temperature deviation or error relative to a reference thermocouple of the same type. This method can be used to verify deviations introduced by the connector greater than or equal to 1 °C. 1.3 The connector is tested with thermocouple contacts axially aligned with a temperature gradient using a specified thermal boundary condition. The actual temperature difference developed across the connector and corresponding error will depend on the connector design. 1.4 Connector contacts are often fabricated from raw materials having temperature-emf relationships in accordance with Specification E230/E230M . However, verifying Specification E230/E230M tolerances is not within the scope of this method. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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. 1.7 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 A thermocouple connector, exposed to a temperature difference, contributes to the output of a thermocouple circuit. The output uncertainty allocated to the connector depends on the connector design and temperature gradient. 5.2 Connector performance can be classified based on the results of this method and used as part of a component specification. 5.3 The method can be used as an engineering tool for evaluating different connector designs tested under similar thermal conditions.
