UL Standard for Safety Requirements for Electrical Equipment for Measurement@ Control@ and Laboratory Use - Part 2-011: Particular Requirements for Refrigerating Equipment (COMMENTS DUE: JANUARY 2@ 2017)
Equipment included in the scope This group safety publication is primarily intended to be used as a product safety standard for the products mentioned in the scope@ but shall also be used by technical committees in the preparation of their publications for products similar to those mentioned in the scope of this standard@ in accordance with the principles laid down in IEC guide 104 and ISO/IEC Guide 51. This Part 2 of IEC 61010 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 whether an integral part of@ or remote to the equipment and the equipment is in direct control of the REFRIGERATING SYSTEM. This Part 2 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 standard apply if a refrigerant charge of FLAMMABLE REFRIGERANT exceeds this amount. NOTE 101 Examples for REFRIGERATING EQUIPMENT include@ but are not limited to@ laboratory equipment such as laboratory refrigerators@ freezers@ refrigerated display cabinets@ etc. If all or part of the equipment falls within the scope of one or more other Part 2 standards of IEC 61010 as well as within the scope of this standard@ it should also meet the requirement of those other Part 2 standards@ In particular@ if equipment is intended to be used as a centrifuge@ it should meet the requirements of IEC 61010-2-020. However@ when the equipment incorporates a REFRIGERATING SYSTEM and a heating function where the combination of the two introduces additional or more sever HAZARDS than if treated separately then the application of IEC 61010-2-012 should be considered instead of this Part 2.
