CSA C22.2 NO. 60335-2-29:20 PDF

Preface:

This is the harmonized CSA Group and UL standard for Household and Similar Electrical Appliances – Safety – Part 2-29: Particular Requirements for Battery Chargers. It is the fourth edition of CSA C22.2 No. 60335-2-29 and the first edition of UL 60335-2-29. This edition of CSA C22.2 No. 60335-2-29 supersedes the previous edition published in 2006 as CAN/CSA-E60335-2-29 (adopted IEC 60335-2-29:2003).

This harmonized standard is based on IEC Publication 60335-2-29: Edition 5.1, Household and similar electrical appliances – Safety – Part 2-29: Particular requirements for battery chargers, issued March 2019. IEC 60335-2-29 is copyrighted by the IEC.

This harmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee are gratefully acknowledged.

This standard is considered suitable for use for conformity assessment within the stated scope of the standard.

This standard was reviewed by the CSA Technical Committee on Consumer and Commercial Products, under the jurisdiction of the CSA Strategic Steering Committee on requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope:

This part of IEC 60335 deals with the safety of electric battery chargers for household and similar use having an output not exceeding 250 V ripple-free direct current, their rated voltage being not more than 250 V.

This standard covers the above-noted products that are intended to be installed or used in accordance with:

• CSA C22.1, Canadian Electrical Code (CE Code), Part I;
• NFPA 70, National Electrical Code (NEC), in the United States.

Battery chargers intended for charging batteries in a household end use application outside the scope of the IEC 60335 series of standards are within the scope of this standard.

Requirements for battery chargers for use by children at least 8 years old without supervision are given in Annex AA.

Annex AA, which is a normative annex in IEC 60335-2-29, is included in this Standard as an informative annex for reference only.

Battery chargers not intended for normal household use, but which nevertheless may be a source of danger to the public, such as battery chargers intended for use in garages, shops, light industry and on farms, are within the scope of this standard.

Battery chargers intended for use in a commercial environment are within the scope of this standard.

The following list, although not comprehensive, gives an indication of commercial environments:

• public use areas such as hotels, schools, hospitals;
• retail outlets, for example shops and supermarkets;
• business premises, for example offices and banks.

As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account

• persons (including children) whose physical, sensory or mental capabilities; or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;
• children playing with the appliance.

NOTE 101 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;
• in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities.

NOTE 102 This standard does not apply to

• built-in battery chargers, except those for installing in caravans and similar vehicles;
• battery chargers that are part of an appliance, the battery of which is not accessible to the user;
• battery chargers intended exclusively for industrial purposes;
• battery chargers intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
• battery chargers for emergency lighting (IEC 60598-2-22);
• supply units for electronic equipment.
• battery chargers installed on land vehicles, including caravans;
• battery chargers installed on marine craft;
• automotive battery chargers;
• battery chargers for e-mobility devices and e-bikes, provided the batteries are separately charged;
• battery chargers that are part of an appliance, the battery of which is not accessible to the user;
• battery chargers intended exclusively for industrial purposes where use by trained operators in an environment that is not accessible by the general public is relied upon as a measure of risk reduction;
• battery chargers for emergency lighting;
• battery chargers for uninterruptable power supplies;
• DC distribution boards.

NOTE 103DV This Part 2-29 may be employed for investigation of components and sub-assemblies for the purpose of their pre-selection for use in appliances. If the component or sub-assembly used complies with this standard, the tests for the component or sub-assembly specified in the particular appliance standard in some cases will not need to be made in the particular appliance or assembly. Additional testing on a component or subassembly might be required. For example, if a control system is associated with the particular appliance control system, additional tests could potentially be necessary on the final appliance.
