CSA Preface

This is the third edition of CSA C22.2 No. 60335-2-35, Household and similar electrical appliances - Safety - Part 2-35: Particular requirements for instantaneous water heaters, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60335-2-35 (edition 5:2012 consolidated with Amendment 1:2016 and Amendment 2:2020). It supersedes the previous edition, published in 2001 as CAN/CSA-E60335-2-35 (adopted IEC 60335-2-35:1997). It also replaces the requirements for instantaneous water heaters found in CSA C22.2 No. 64:19, Household cooking and liquid-heating appliances. It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. For brevity, this Standard will be referred to as "CSA C22.2 No. 60335-2-35" throughout. This Standard is intended to be used in conjunction with CAN/CSA-C22.2 No. 60335-1:16, Household and similar electrical appliances - Safety - Part 1: General requirements (adopted IEC 60335-1:2010+A1:2013, with Canadian deviations). This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. 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 clause of Part 1 is replaced by the following. This International Standard deals with the safety of electric instantaneous water heaters for household and similar purposes and intended for heating water below boiling temperature, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances.

NOTE 101 Instantaneous water heaters incorporating bare heating elements are within the scope of this standard. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended for use in shops, in light industry and on farms, are within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by appliances which 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 102 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;

- in many countries regulations exist for the installation of equipment connected to the water mains.

NOTE 103 This standard does not apply to

- appliances for heating liquids (IEC 60335-2-15);

- storage water heaters (IEC 60335-2-21);

- appliances intended exclusively for industrial purposes;

- appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);

- commercial dispensing appliances and vending machines (IEC 60335-2-75).
