Foreword
This document was drafted in accordance with the rules given in GB/T 1.1-2020
"Directives for standardization - Part 1.Rules for the structure and drafting of
standardizing documents".
This document is Part 17 of GB/T 4706 "Safety of household and similar electrical
appliances". The following parts of GB/T 4706 have been issued.
- Part 1.General requirements;
- Part 2.Particular requirements for electric irons;
- Part 121.Particular requirements for professional ice-cream makers.
This document replaces GB 4706.17-2010 "Safety of household and similar electrical
appliances -- Particular requirements for motor-compressors". Compared with GB
4706.17-2010, in addition to structural adjustments and editorial changes, the main
technical changes in this document are as follows.
- Change the applicable range of rated voltage of the appliance (see Chapter 1 of this
Edition; Chapter 1 of Edition 2010). Add examples of types of devices equipped
with motor-compressors (see Chapter 1 of this Edition);
- Add the term definitions and related test requirements for application categories
(see 3.1.102, Annex AA of this Edition);
- Add the definition of two-stage motor-compressor (see 3.5.102 of this Edition);
- Add the term and definition of motorette and winding wire compatibility test (see
3.8.102, Annex BB of this Edition);
- Add speed requirements for variable speed motor-compressor tests (see 5.6 of this
Edition);
- Add the requirement to declare the type of protection used by the motor (see 5.102,
6.104 of this Edition);
- Add test requirements for cascade systems containing two or more motor-
compressors (see 5.103 of this Edition);
- Add the fire protection signs for flammable refrigerants and their use requirements
(see 7.1 and 7.6 of this Edition);
- Add requirements for warning sign height (see 7.14 of this Edition);
- Add requirements to replace the heating test in Chapter 11 with Annex AA. Clarify
the heating test requirements for motor-compressors that do not need to undergo
the Annex AA test according to classification (see Chapter 11 of this Edition);
- Add optional fatigue test (see 18.101, Annex EE of this Edition);
- Add motor-compressor fault test with electronic circuit (see 19.11.2, AA.3 of this
Edition);
- Add requirements for motor-compressors when using flammable refrigerants for
related tests (see 19.13, 24.101 of this Edition);
- Add pressure test for subcritical refrigeration system and transcritical refrigeration
system using R744 refrigerant (see 22.7 of this Edition);
- Add insulation material compatibility test (see 22.9, Annex BB and Annex CC of
this Edition);
- Add the minimum insulation thickness requirements for easily accessible
reinforced insulation at different rated voltages (see 29.1, 29.3.4 of this Edition);
- Add the requirements for electrical clearances for motor-compressors applicable to
high altitudes (see 29.1 of this Edition);
- Change the operating overload test conditions (see AA.1, AA.2, AA.3 of this
Edition; Annex AA of Edition 2010).
This document identically adopts IEC 60335-2-34.2021 "Household and similar
electrical appliances - Safety - Part 2-34.Particular requirements for motor-
compressors".
The following minimal editorial changes were made to this document.
- The name of the standard was changed to "Safety of household and similar
electrical appliances - Part 17.Particular requirements for motor-compressors" to
enhance the coordination of the standard system.
