1.1 本规范涵盖了测试操作中通常使用的通用空气烘箱的性能要求，该烘箱的测试室高达0.6 m 3. （25英尺 3. )体积。 1.2 它适用于设计用于在高于环境室温20°C至200°C的全部或部分温度范围内运行的重力对流炉。 1.3 它适用于设计用于在高于环境室温20°C至500°C的全部或部分温度范围内运行的强制通风烘箱。 1.4 本规范不包括对存在可燃材料的烘箱至关重要的安全要求。 1.5 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考，可能是近似值。 1.5.1 温度表达式的国际单位制基本单位为开尔文（K），本规范中使用的测量单位为摄氏度（°C），并通过数学推导得出。 1.6 本标准的校准炉是确保其在典型使用条件下的操作性能所必需的，并且应根据制造商的建议、最终用户、其客户或供应商的质量要求定期进行。 1.7 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。 1.8 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 performance requirements for general purpose air ovens ordinarily used in testing operations, which have a testing chamber up to 0.6 m 3 (25 ft 3 ) in volume. 1.2 It is applicable to gravity convection ovens designed to operate over all or part of the temperature range from 20°C above ambient room temperature to 200°C. 1.3 It is applicable to forced ventilation ovens designed to operate over all or part of the temperature range from 20°C above ambient room temperature to 500°C. 1.4 This specification does not include safety requirements that are essential for ovens used in the presence of combustible materials. 1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for reference only and may be approximate. 1.5.1 The SI base unit of the expression of temperature is Kelvin (K), the unit of measure used in this specification is Celsius (°C) and has been derived mathematically. 1.6 Calibration ovens to this standard are necessary to assure their operative performance under typical conditions of use and shall be performed periodically, either according to the manufacturer’s recommendations, the quality requirements of the end user, their customers, or suppliers. 1.7 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. 1.8 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.
