CAN/CSA-E335-2-69-94

1 Scope This clause of Part 1 is applicable except as follows: 1.1 Replacement: This standard applies to electrical motor-operated vacuum cleaners with a power input up to 10 kW and includes appliances and stationary equipment specifically designed for wet suction, dry suction, or wet and dry suction for industrial and commercial use with or without attachments, for example for suction to withdraw dust or the like from work benches and production machines. Commercial uses are for example for use in hotels, schools, hospitals, factories, shops and offices for other than normal housekeeping purposes. It is under consideration that this standard also applies to machines handling hazardous dust, for example asbestos or liquids for which additional requirements apply. This standard 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 for household and similar use to which IEC 335-2-2 applies; - centrally sited stationary vacuum cleaning systems; - 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). 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.
