This National Standard of Canada is based on International Standard CEI/IEC 335-1:1976. 1. Scope 1.1 This standard applies to electric heating appliances and electric
motor-operated or magnetically-driven appliances for household and
similar purposes. This Standard applies to the safety of such equipment designed to be
installed and used in accordance with the rules of the Canadian
Electrical Code (CEC), Part I.
Note: Manufacturers designing products for use in Canada may find a
helpful summary of the equipment-related requirements of the CEC, Part
I, in CSA Publication Spe-2000. Appliances not intended for normal household use, but which
nevertheless may 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. Examples of such
appliances are appliances for hairdressers, soldering irons, glue pots,
sterilizers, infra-red radiation appliances, feed boilers, water pumps
and lawn mowers. Except in so far as this standard deals with electric toys, it does not
take into account the special hazards which exist in nurseries and
other places where there are young children or aged or infirm persons
without supervision; in such cases additional requirements may be
necessary. This Standard does not apply to: - appliances designed 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); - separate motors; - appliances for high frequency heating except microwave ovens; - fans (IEC Publication 342: Safety Requirements for Electrical Fans
and Regulators); - radio and television receiving appliances (IEC Publication 65: Safety
Requirements for Mains Operated Electronic and Related Apparatus for
Household and Similar General Use); - appliances for medical purposes. - Gramaphones and similar motor-operated appliances intended to be used
in, or in combination with, electronic equipment are tested together
with such equipment, in accordance with IEC Publication 65. For appliances intended to be used in vehicles or on board ships or
aircraft, additional requirements may be necessary. For appliances intended to be used in tropical countries, special
requirements may be necessary. Attention is drawn to the fact that in many countries additional
requirements are specified by the national health authorities and the
national authorities responsible for the protection of labour. 1.2 This Standard is concerned with safety and takes into account the
influence on safety of components necessary to achieve a required
degree of radio and television interference suppression.
