This draft amendment prAB, if approved, will modify the European Standard EN IEC 60335-2-34:2023; it is submitted to CENELEC
members for enquiry.
Deadline for CENELEC: 2024-08-09.

It has been drawn up by CLC/TC 61.

If this draft becomes an amendment, 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.

This draft amendment was established by CENELEC 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.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus, the Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the
Netherlands, Norway, Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,

European foreword
This document (EN IEC 60335-2-34:2023/prAB:2024) has been prepared by CLC/TC 61 “Safety of household
and similar electrical appliances”.
This document is currently submitted to the Enquiry.
The following dates are proposed:
• latest date by which the existence of this document (doa) dor + 6 months
has to be announced at national level
• latest date by which this document has to be (dop) dor + 12 months
implemented at national level by publication of an
identical national standard or by endorsement
• latest date by which the national standards (dow) dor + 36 months
conflicting with this document have to be withdrawn (to be confirmed or
modified when voting)
This document is read in conjunction with EN IEC 60335-2-34:2023 and EN IEC 60335-2-34:2023/A11:2023.
The numbering system for European clauses, subclauses, notes, tables, figures and annexes that are additional
to those in the IEC standard are prefixed with the letter “Z”.
This document has been prepared under a standardization request addressed to CENELEC by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZZA and Annex ZZB, which are an integral part
of this document.
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)
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 in not applicable.
Delete subclause 18.101.
5 Modification to Clause 22, “Construction”
22.7 Modification the first line of the compliance criteria:
Compliance is checked by the following test or the fatigue test specified in Annex EE.
6 Modification to annexes
