1 Scope and objectThis clause of Part 1 is applicable, except as follows:1.1.1 Equipment included in scopeReplacement:Replace the second paragraph by the following:This Part 2 of IEC 61010 specifies particular safety requirements for the following typesa) 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, orseparate from, the equipment and the equipment is in direct control of the REFRIGERATINGSYSTEM.This document details all the requirements when up to 150 g of FLAMMABLE REFRIGERANT areused per stage of a REFRIGERATING SYSTEM. Additional requirements beyond the current scopeof this document apply if a REFRIGERANT charge of FLAMMABLE REFRIGERANT exceeds thisamount.Addition:Add the following text after the last paragraph:NOTE 101 Examples for REFRIGERATING EQUIPMENT include, but are not limited to, laboratory equipment such aslaboratory refrigerators, freezers, refrigerated display cabinets.It is possible that all or part of the equipment falls within the scope of one or more otherPart 2 standards of IEC 61010 as well as within the scope of this standard. In that case, therequirements of those other Part 2 standards will also apply. In particular, if equipment isintended to be used as a centrifuge, the requirements of IEC 61010-2-020 apply. However,when the equipment incorporates a refrigerating system and a heating function where thecombination of the two introduces additional or more severe HAZARDS than if treatedseparately, then it is possible that IEC 61010-2-012 is applicable instead of this Part 2-011.See further information in the flow chart (Figure 102) for the selection process and guidancein the Introduction.1.1.2 Equipment excluded from scopeAddition:Add the following new item after item j):or equipment incorporating:aa) a transcritical REFRIGERANT SYSTEM (system that uses CO2) or a system that usesammonia (NH3) as the REFRIGERANT.1.2 Object1.2.1 Aspects included in scopeReplacement:Replace the first paragraph by the following:The object of this document is to ensure that the design and methods of construction ofREFRIGERATING EQUIPMENT provide adequate protection for OPERATORS, bystanders, trainedservice personnel, and the surrounding area against the specific HAZARDS that relate toREFRIGERATING SYSTEMS.Addition:Add the following note after the existing note:NOTE 101 A list of HAZARDS typically associated with REFRIGERATING SYSTEMS and REFRIGERANTS is included inAnnex BB.
