Safety requirements for electrical equipment for measurement, control, and laboratory use – Part 2-011: Particular requirements for refrigerating equipment
|Publication Date:||1 July 2016|
|ICS Code (Electrical and electronic testing):||19.080|
Equipment included in scope
This part of IEC 61010 specifies general safety requirements for electrical equipment intended for professional, industrial process, and educational use, any of which may incorporate computing devices, as defined in a) to d) below, when used under the environmental conditions of 1.4.
a) Electrical test and measurement equipment
This is equipment which by electrical means tests, measures, indicates or records one or more electrical or non-electrical quantities, also non-measuring equipment such as signal generators, measurement standards, power supplies, transducers, transmitters, etc.
NOTE All indicating and recording electrical measuring instruments (except those excluded in 1.1.2) fall within the scope of IEC 61010 unless they are panel meters designed only for building-in to other equipment. Built-in panel meters are considered to be components and only need to meet the relevant requirements of IEC 61010, or other standards, as part of the equipment into which they are built.
b) Electrical 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 or analyses substances, or is used to prepare materials, and includes in vitro diagnostic (IVD) equipment
This equipment may also be used in areas other than laboratories, for example self-test IVD equipment may be used in the home.
d) Accessories intended for use with the above (for example, sample handling equipment).
Equipment excluded from scope
This standard does not apply to equipment within the scope of
a) IEC 60065 (Safety requirements for audio, video and similar electronic apparatus);
b) IEC 60204 (Controls for electrical machines);
c) IEC 60335 (Safety of household and similar electrical appliances);
d) IEC 60364 (Electrical installations of buildings);
e) IEC 60439-1 (Low-voltage switchgear and controlgear assemblies);
f) IEC 60521 (Class 0,5; 1 and 2 alternating current watthour meters);
g) IEC 60601 (Medical electrical equipment);
h) IEC 60950 (Safety of information technology equipment including electrical business equipment, except as specified in 1.1.3);
i) IEC 61558 (Power transformers, power supply units and similar).
This standard applies only to computers, processors, etc. which form part of equipment within the scope of this standard or are designed for use exclusively with the equipment.
NOTE Computing devices and similar equipment within the scope of IEC 60950 and conforming to its requirements are considered to be suitable for use with equipment within the scope of this standard. However, some of the requirements of IEC 60950 for resistance to moisture and liquids are less stringent than those in this standard. If HAZARDS from moisture or liquids could affect equipment that conforms to IEC 60950 and is used with equipment which conforms to this standard, the instructions for use should specify any additional precautions required.
Equipment included in the scope
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.
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.
Equipment excluded from scope
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.
