Household and similar electrical appliances - Safety - Part 2-34: Particular requirements for motor-compressors

This European Standard deals with the safety of sealed (hermetic and semi-hermetic type) motor-compressors, their protection and control systems, if any, which are intended for use in equipment for household and similar purposes and which conform with the standards applicable to such equipment. It applies to motor-compressors tested separately, under the most severe conditions that may be expected to occur in normal use, their rated voltage being not more than 250 V for single-phase motor-compressors and 480 V for other motor-compressors

This amendment A12 modifies the European Standard EN IEC 60335-2-34:2023; it was approved by CENELEC on 2025-06-16. CENELEC
members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this amendment the
status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC
Management Centre or to any CENELEC member.
This amendment exists in three official versions (English, French, German). A version in any other language made by translation under the
responsibility of a CENELEC member into its own language and notified to the CEN-CENELEC Management Centre has the same status as
the official versions.

European foreword
This document (EN IEC 60335-2-34:2023/A12:2025) has been prepared by CLC/TC 61 “Safety of household
and similar electrical appliances”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2026-07-31
implemented at national level by publication of an
identical national standard or by endorsement
• latest date by which the national standards (dow) 2028-07-31

1 Modification to the Introduction
Addition:
This European Amendment A12 supplements or modifies the corresponding clauses of the standards below:
— EN 60335-1:2012+A11:2014+A13:2017+A1:2019+A14:2019+A2:2019+A15:2021+A16:2023 (Part 1)
— EN IEC 60335-2-34:2023+A11:2023 (Part 2)
Additional requirements for appliances with power driven parts intended for commercial use are given in
Annex ZE.
This European standard does not deal with any specific requirements on noise emitted from these appliances
the generated noise is not considered to be a relevant hazard. Thus, the emission sound pressure level LpA is
considered to be LpA ≤ 70 dB(A).
2 Modification to Clause 6, “Classification”
6.101 Replace this clause with the following:
“Motor-compressors shall be classified as being tested with Annex AA or without Annex AA.
Motor-compressors shall be classified as being tested with Annex AA only if the motor-compressor in
combination with the motor-compressor protection system or motor-compressor control system, if any,
can be configured to operate so as to deliver maximum cooling capacity, independently of any input sensors
that are only provided as part of the final application.”
3 Modification to Clause 7, “Marking and instructions”
7.12.1 Addition
Motor-compressors technical documentation shall include instructions for installation, servicing and eventual
dismantling and disposal.
Compliance is checked by inspection
7.101 Modification
Motor-compressor technical documentation (published datasheet) shall list the following:
1. refrigerants that can be used with motor-compressor
2. if motor-compressor is classified with or without Annex AA
3. if motor-compressor has incorporated or associated electronic circuit
4. housing internal volume and relative maximum allowable pressure (PS)
5. locked rotor amperage (LRA) for motor-compressors without electronic circuit or with the maximum
current value as measured before cut off for motor-compressors with incorporated or associated
electronic circuit
Compliance is checked by inspection.
4 Modification to Clause 18, “Endurance”
This clause of Part 1 is not applicable.
Delete subclause 18.101.
5 Modification to Clause 22, “Construction”
