IEC 60034-12:2024 is available as IEC 60034-12:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60034-12:2024 specifies the parameters for eight designs of starting performance of single-speed three-phase 50 Hz or 60 Hz cage induction motors in accordance with IEC 60034‑1 that: - have a rated voltage up to 1 000 V; - are intended for direct-on-line or star-delta starting; - are rated on the basis of duty type S1; - are constructed to any degree of protection as defined in IEC 60034-5 and explosion protection. This document also applies to dual voltage motors provided that the flux saturation level is the same for both voltages. This fourth edition cancels and replaces the third edition published in 2016. Aligned with the requirements for explosion protected motors from TC31 WG27 - new clause on methods for measuring locked-rotor current and torque; - new informative annex on the general current and torque characteristics with locked rotor; - new informative annex on correction of voltage and frequency; - aligned with the requirements for explosion protected motors from TC31 WG27.

IEC 60335-2-39:2012 deals with the safety of electrically operated commercial multi-purpose cooking pans not intended for household and similar use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances. This standard also deals with pressurized appliances and appliances with pressurized parts. These appliances are used for processing food for commercial consumption, for example in kitchens of restaurants, canteens, hospitals and in commercial enterprises such as bakeries, butcheries, etc. The electrical part of appliances making use of other forms of energy is also within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by these types of appliances. Attention is drawn to the fact that for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary. The principal changes in this edition as compared with the fifth edition of IEC 60335-2-39 are as follows (minor changes are not listed): - addition to definition of portable appliances, atmospheric multi-purpose cooking and rated pressure; - deletion of equipotential symbol 5021 of IEC 60417 covered by Part 1; - addition of instructions for multi-purpose cooking pans; - modification on leakage current permissible for portable class l appliances; - addition to abnormal test requirements; - addition to mechanical hazard test for multi-purpose cooking pans; - addition of construction test for multi-purpose cooking pans; - addition to construction requirements for lids and theirs grips; - addition to construction requirements for positioning of pressure reliefs; - addition to construction's fixed appliances which are moved forward and backward for cleaning purposes.
The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of publication. Keywords: Multi-purpose cooking pans.

This European Standard deals with the safety of electric heat pumps, sanitary hot water heat pumps and air conditioners, incorporating motor-compressors as well as hydronic fan coils units, dehumidifiers (with or without motor-compressors), thermoelectric heat pumps and partial units. Their maximum rated voltage being not more than 300 V for single phase appliances and 600 V for multi-phase appliances. Appliances not intended for normal household use but which nevertheless can be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.

IEC 60034-11:2020 is available as IEC 60034-11:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60034-11:2020 specifies requirements relating to the use of thermal protectors and thermal detectors incorporated into the stator windings or placed in other suitable positions in induction machines in order to protect them against serious damage due to thermal overloads. It applies to single-speed three-phase 50 Hz or 60 Hz cage induction motors in accordance with IEC 60034-1 and IEC 60034-12 that: - have a rated voltage up to 1 000 V; - are intended for direct-on-line or star-delta starting. The main changes with respect to the previous edition are: - the additional specification of winding temperature limits for temperature class 200 (N), - the increased limits of maximum winding temperatures for overloads with rapid variation, - the clarification that the motor winding may be permanently damaged after it has been exposed to temperatures - a clarification of the definition of indirect thermal protection, - a clarification on the test methods for larger motors.
