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，该烘箱具有高达0.6 m的测试室 3 （25英尺 3 ）体积。它适用于设计为在高于环境温度20℃至200℃的全部或部分温度范围内运行的重力对流烘箱，以及设计为在高于环境温度20℃至500℃的全部或部分温度范围内运行的强制通风烘箱。 附注1: 烘箱设计用于约200℃、300℃和500℃的最高工作温度，烘箱的隔热和成本取决于所需的最高温度。 1.2 本规范不包括在存在可燃蒸汽或气体的情况下使用的烤箱所必需的安全要求。1.3 以SI单位表示的值将被视为标准值。SI单位后括号中给出的值仅供参考，不被视为标准值。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 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. It is applicable to gravity-convection ovens designed to operate over all or part of the temperature range from 20 °C above ambient temperature to 200 °C and to forced-ventilation ovens designed to operate over all or part of the temperature range from 20 °C above ambient temperature to 500 °C. Note 1: Ovens are designed for maximum operating temperatures of about 200 °C, 300 °C, and 500 °C, the thermal insulation and cost of the oven being dependent on the maximum temperature required. 1.2 This specification does not include safety requirements that are essential for ovens used in the presence of combustible vapors or gases. 1.3 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. 1.4 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.
