测量、控制和实验室用电气设备的安全要求第2-012部分:气候和环境试验及其他温度调节设备的特殊要求

[中文适用范围]： 本部分IEC 61010规定了电气测量、控制和实验室设备及其附件的安全要求，适用于各类别a)至c)，只要该设备 incorporates 一个或多个以下特征： - 一个制冷系统受到或受整体加热功能的影响，使得组合的加热和制冷系统产生的危险大于将两个系统单独处理时的危险； - 在预期应用中处理的物料向制冷系统引入显著热量，使得该制冷系统在应用中的危险大于仅在最大额定环境温度下运行的制冷系统产生的危险； - 对处理的物料进行照射功能，带来额外的危险； - 使处理的物料暴露于过量湿度、二氧化碳、盐雾或其他可能导致额外危险的物质的功能； - 呈现额外危险的机械运动功能； - 允许操作员进入操作区域以装载或卸载被处理物料的设施。 此类设备的示例包括环境测试室和植物生长试验室、带有加热功能的制冷循环器以及用于提取热量的再循环冷却器。 [外文原描述]： IEC 61010-2-012:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61010-2-012:2019 specifies safety requirements for electrical equipment and its accessories within the categories a) through c), wherever it is intended to be used, whenever that equipment incorporates one or more of the following characteristics: – A refrigerating system that is acted on or impacted by an integral heating function such that the combined heating and refrigerating system generates additional and/or more severe hazards than those for the two systems if treated separately. – The materials being treated in the intended application introduce significant heat into the refrigerating system, so that the refrigerating system in the application yields additional and/or more severe hazards than those for the refrigerating system if operated at the maximum rated ambient temperature alone. – An irradiation function for the materials being treated presenting additional hazards. – A function to expose the materials being treated to excessive humidity, carbon dioxide, salt mist, or other substances which can result in additional hazards. – A function of mechanical movement presenting additional hazards. – Provision for an operator to walk in to the operating area to load or unload the materials being treated. It has the status of a group safety publication in accordance with IEC Guide 104. This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment with changes introduced by Amendment 1 of IEC 61010-1:2010; b) changes related to the use of small capitals for defined terms only; c) clarifications for cooling tests in 4.4.2.10; d) requirements for overtemperature protection in 10.101, including deletion of the second part of the sentence in item b), and the deletion of item c); e) changes pertaining to the accurate employment of terms "temperature", "operating temperature", "working temperature", "application temperature", "room temperature" and "ambient temperature" in 3.5.104, 3.5.105, 4.3.1, 4.3.2, 5.4.2, 8.2.1, 8.2.2, 11.7.2.101.2, 11.7.2.101.3, 13.2.102, 14.102, 15.101, 15.102, 15.103, Introduction and many other locations. For the purpose of clarification, the definition of 3.5.114, controlled temperature, is added.
