测量、控制和实验室用电气设备的安全要求.第2-011部分:制冷设备的特殊要求

[中文适用范围]： 本文件是IEC 61010-2-011标准，规定了用于测量、控制和实验室使用的电气设备及其配件的特定安全要求，前提是这些设备包含制冷系统（作为设备的一部分或独立部分），且设备直接控制该制冷系统。本文件详细规定了每级制冷系统使用的易燃制冷剂不超过150克时的所有要求。如果易燃制冷剂的充注量超过此数量，则适用超出本文件范围的其他要求。示例包括实验室冰箱、冷冻柜、冷藏展示柜等。 [外文原描述]： IEC 61010-2-011:2019 specifies particular safety requirements for the following types a) to c) of electrical equipment and their accessories, wherever they are intended to be used, whenever that equipment incorporates refrigerating systems as an integral part of, or separate from, the equipment and the equipment is in direct control of the refrigerating system. This document details all the requirements when up to 150 g of flammable refrigerant are used per stage of a refrigerating system. Additional requirements beyond the current scope of this document apply if a refrigerant charge of flammable refrigerant exceeds this amount. a) Electrical test and measurement equipment This is equipment which by electromagnetic means tests, measures, indicates or records one or more electrical or physical quantities, also non-measuring equipment such as signal generators, measurement standards, power supplies for laboratory use, transducers, transmitters, etc. b) Electrical industrial process-control equipment This is equipment which controls one or more output quantities to specific values, with each value determined by manual setting, by local or remote programming, or by one or more input variables. c) Electrical laboratory equipment This is equipment which measures, indicates, monitors, inspects or analyses materials, or is used to prepare materials, and includes in vitro diagnostic (IVD) equipment. 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) introduction of new defined terms or modified terms to align with Part 2-012 and other source documents. Editorial changes to use small capitals only for defined terms. Note the difference of defined term in 4.3.2.101 and abnormal operation in 11.7.104.3 and 11.7.104.5; c) clarifications for cooling tests in 4.4.2.10; d) changes pertaining to the accurate employment of the following terms: temperature, operating temperature, application temperature, controlled temperature, room ambient and ambient temperature; e) use of defined term to replace cooling system; f) move text of 4.4.2.101 to 4.3.2.101, since the purpose of as defined, is to simulate failure of the ambient conditions of 1.4.1 but not of the of the equipment; g) use of the term equipment to replace unit, apparatus, appliance, where applicable; h) in 5.1.2 dd) for high and low sides for each stage are required only under ; i) use of defined term to replace normal operation; j) use of defined term to replace user. It has the status of a group safety publication in accordance with IEC Guide 104.
