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]： 本部分规定了电气测量、控制和实验室设备及其配件的特定安全要求，无论其使用场合如何，只要这些设备将制冷系统作为其整体或部分集成，并对制冷系统进行直接控制。本文件详细规定了每个制冷阶段使用易燃制冷剂不超过150克时的所有要求。如果易燃制冷剂的充注量超过此数量，则适用本文件范围之外的额外要求。示例包括实验室冰箱、冷冻柜、制冷展示柜等。如果设备作为离心机使用，则IEC 61010-2-020的要求也适用。但是，当设备结合制冷系统和加热功能，且两者的结合产生的危害比单独处理时更严重或更多时，可能适用IEC 61010-2-012而不是本部分。 [外文原描述]： IEC 61010-2-011:2019 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 61010-2-011:2019 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.
