JWG 2 - TC 59/JWG 2

IEC 60704-1:2021 is available as IEC 60704-1:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60704-1:2021 applies to electric appliances (including their accessories or components) for household and similar use, supplied from mains or from batteries.
By "similar use" is understood the use in conditions similar to those found in households, for example in inns, coffee houses, tea rooms, hotels, barber or hairdresser shops, launderettes, etc., if not otherwise specified in the IEC 60704-2 series.
This document does not apply to:
– appliances, equipment, or machines designed exclusively for industrial or professional purposes;
– appliances that are integrated parts of a building or its installations, such as equipment for air conditioning, heating and ventilating (except household fans, cooker hoods, free-standing heating appliances, dehumidifiers, air cleaners, and stand-alone water heaters), oil burners for central heating, pumps for water supply and for sewage systems;
– separate motors or generators and
– appliances exclusively for outdoor use.
For determining and verifying noise emission values declared in product specifications, see IEC 60704-3:2019.
This fourth edition cancels and replaces the third edition published in 2010. This edition constitutes a technical revision.
It includes the following significant changes with respect to the previous edition:
a) update of references (especially to ISO standards);
b) revision of requirements on climatic conditions;
c) revision of requirements on background noise level.

IEC 60704-3:2019 is available as IEC 60704-3:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60704-3:2019 describes procedures for determining and verifying the declared values of the noise emitted by household and similar appliances. It applies to all categories of household and similar electrical appliances covered by IEC 60704-1 and all parts of IEC 60704-2, which include particular requirements for special categories of appliances. It applies to appliances being produced in quantity, such as in batches, series or lots, which are manufactured to the same technical specification and characterized by the same declared value of noise emission. This part of IEC 60704:
– considers the term "declaration" to include all means for providing information on the noise emission values to potential users (consumers) of the appliances; this includes labels, brochures, advertisements, commercial and technical information papers, etc.;
– considers the declaration for appliances manufactured by mass production;
– specifies a simple statistical method for verifying the declared values by investigating a sample of only three appliances.
This International Standard is to be used in conjunction with IEC 60704-1:2010 and the latest edition of IEC 60704-2 (all parts).
This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision. It includes the following significant technical changes with respect to the previous edition:
a) in Annex A, standard deviations that are now specified for various appliance categories in the parts of IEC 60704-2 have been excluded from Table A.1;
b) furthermore, this edition makes reference to new standards and is implementing ISO/IEC Directives, Part 2 in a more accurate manner.

IEC 60704-1:2010 applies to electric appliances (including their accessories or components) for household and similar use, supplied from mains or from batteries. By similar use is understood to be the use in similar conditions as in households, for example in inns, coffee-houses, tea-rooms, hotels, barber or hairdresser shops, launderettes, etc., if not otherwise specified in part 2. The principal changes in this edition as compared to the previous edition are as follows: includes a description of an appropriate test enclosure for appliances to be built in.

IEC 60050-851:2008, which is a part of the IEV, defines terms specifically relevant to electric welding. This second edition cancels and replaces the first edition published in 1991. This edition constitutes a technical revision. This edition included the following significant technical changes with respect to the previous edition: Due to technical and standardisation progress, new entries had to be made in the sections. The changes in this listing are not numbered as the numbering of this edition is different to the previous edition. The changes are as follows:
- Section 11: This section augmented to take into consideration the development in general.
- Section 12: New terms are added taking care of engine (motor) driven equipment and arc striking and stabilizing devices.
- Section 13: New terms dealing with plasma welding equipment.
- Section 14: The terms concerning consumables had to be enlarged and terms concerning welding equipment such as wire feeders, cooling systems and gas consoles are added.
- Section 15: This section is completely new with the exception of two terms.
It has the status of a horizontal standard in accordance with IEC Guide 108.
