1.1 本规范涵盖强制对流通风电加热烤箱，在20 高于环境温度500°C °C，并用于电绝缘材料的耐热性评估。 1.2 I型烤箱的规范要求基于IEC出版物60216-4-1，在技术上与之相同。II型烤箱的要求基本上与规范的要求相同 第2436页 本说明书和相关的测试方法， D5374型 ，已替换规范 第2436页 . 1.3 虽然本规范涵盖的烤箱主要用于耐热性评估，但其特性使其适用于其他应用。 1.4 以国际单位制表示的值应视为标准值。 本标准不包括其他测量单位。 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建立适当的安全、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（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers forced-convection ventilated electrically-heated ovens, operating over all or part of the temperature range from 20 °C above the ambient temperature to 500 °C, and used for thermal endurance evaluation of electrical insulating materials. 1.2 The specification requirements for Type I ovens are based on IEC Publication 60216-4-1, and are technically identical to it. The requirements for Type II ovens are essentially identical to the requirements of Specification D2436 . This specification and an associated test method, D5374 , have replaced Specification D2436 . 1.3 While the ovens covered by this specification are intended primarily for thermal endurance evaluation, their characteristics make them suitable for other applications as applicable. 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.
