UL 61010-2-011

1 Scope and object
This clause of Part 1 is applicable, except as follows:
1.1.1 Equipment included in the scope
Replacement:
Replace the first paragraph by the following:
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.
Addition:
Add the following text after the last paragraph:
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.
See further information in the flow chart for the selection process and guidance in the Introduction.
1.1.2 Equipment excluded from scope
Addition:
Add the following new item after item j):
aa) equipment incorporating transcritical refrigerant system (system that use CO2) or system that use ammonia (NH3) as the refrigerant.
1.2 Object
1.2.1 Aspects included in scope
Replacement:
Replace the first paragraph by the following:
The object of this Part 2 is to assure that the design and methods of construction of REFRIGERATING EQUIPMENT provide adequate protection for OPERATORS, bystanders, trained service personnel, and the surrounding area against the specific HAZARDS that relate to REFRIGERATING SYSTEMS.
Addition:
Add the following note after the existing note:
NOTE 101 A list of HAZARDS typically associated with REFRIGERATING SYSTEM and refrigerants is included in Annex bb.
