|Publication Date:||1 October 2017|
|ICS Code (Electrical and electronic testing):||19.080|
Equipment included in scope
This part of IEC 61010 specifies general safety requirements for the following types of electrical equipment and their accessories, wherever they are intended to be used.
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.
NOTE 1 This includes bench-top power supplies intended to aid a testing or measuring operation on another piece of equipment. Power supplies intended to power equipment are within the scope of IEC 61558 (see 1.1.2 h)).
This standard also applies to test equipment integrated into manufacturing processes and intended for testing manufactured devices.
NOTE 2 Manufacturing test equipment is likely to be installed adjacent to and interconnected with industrial machinery in this application.
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 equipment may also be used in areas other than laboratories; examples include selftest IVD equipment to be used in the home and inspection equipment to be used to check people or material during transportation.
Equipment excluded from scope This standard does not apply to equipment within the scope of:
a) IEC 60065 (Audio, video and similar electronic apparatus);
b) IEC 60204 (Safety of machinery - Electrical equipment of machines);
c) IEC 60335 (Household and similar electrical appliances);
d) IEC 60364 (Electrical installations of buildings);
e) IEC 60439 (Low-voltage switchgear and controlgear assemblies);
f) IEC 60601 (Medical electrical equipment);
g) IEC 60950 (Information technology equipment including electrical business equipment, except as specified in 1.1.3);
h) IEC 61558 (Power transformers, power supply units and similar);
i) IEC 61010-031 (Hand-held probe assemblies);
j) IEC 61243-3 (Live working - Voltage detectors - Part 3: Two-pole low-voltage type).
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.
See further information in the flow chart for the selection process and guidance in the Introduction.
aa) equipment incorporating transcritical refrigerant system (system that use CO2) or system that use ammonia (NH3) as the refrigerant.
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.
NOTE 101 A list of HAZARDS typically associated with REFRIGERATING SYSTEM and refrigerants is included in Annex BB.
