CSA C22.2 NO. 60335-2-68:20

Preface:

This is the harmonized CSA Group and UL standard for Household and Similar Electrical Appliances – Safety – Part 2-68: Particular Requirements for Spray Extraction Machines, for Commercial Use. It is the first edition of CSA C22.2 No. 60335-2-68, and the first edition of UL 60335-2-68. This edition of CSA C22.2 No. 60335-2-68 replaces CAN/CSA-E60335-2-68:01 (adopted IEC 60335-2-68:1996), Safety of Household and Similar Electrical Appliances – Part 2: Particular Requirements for Spray Extraction Appliances, for Industrial and Commercial Use.

This harmonized standard is based on IEC Publication 60335-2-68: Fourth edition, Household and Similar Electrical Appliances – Safety – Part 2-68: Particular Requirements for Spray Extraction Machines, for Commercial Use, issued March 2012, as revised by Amendment 1, issued April 2016. IEC 60335-2-68 is copyrighted by the IEC.

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 International Standard deals with the safety of electrical portable, non-self-propelled motor-operated SPRAY EXTRACTION MACHINES with or without attachments and with or without electrical heating elements, intended for commercial indoor use.

NOTE 101 This standard applies to machines for COMMERCIAL USE. The following list, although not comprehensive, gives an indication of locations that are included in the scope:

• public use areas such as hotels, schools, hospitals;
• industrial locations, for example factories and manufacturing shops;
• retail outlets, for example shops and supermarkets;
• business premises, for example offices and banks;
• rental services for those machines;
• all uses other than normal housekeeping purposes.

They are not equipped with a traction drive. The following power systems are covered:

• mains powered motors up to a RATED VOLTAGE of 250 V for single-phase appliances and 480 V for other appliances,
• battery powered motors.

They are not equipped with traction drive. They include the following energy sources or power systems, or combinations of them:

• mains up to a rated voltage of 250 V for single-phase appliances and 480 V for other appliances,
• batteries supplying 150 V or less.

NOTE 102DV Machines for the same intended function but equipped with a traction drive are covered by CAN/CSA-C22.2 No. 60335-2-72/UL 60335-2-72.

It is also possible for covered products to be powered by the following. Additional requirements related to these power sources are not included in this Standard.

• double layer (ultra) capacitors;
• fuel cells.

This standard applies to machines in which the pressure of the employed CLEANING AGENT does not exceed 2,5 MPa, and in which the product of the pressure (in MPa) and the flow of CLEANING AGENT (in litres per minute) does not exceed 100, and in which the temperature of the CLEANING AGENT at the spray nozzle outlet does not exceed 85 °C.

This standard does not apply to

• vacuum cleaners and water-suction cleaning appliances for household use (CSA C22.2 No. 243/UL 1017);
• floor treatment machines for COMMERCIAL USE (CAN/CSA-C22.2 No. 60335-2-67/UL 60335-2-67, CAN/CSA-C22.2 No. 60335-2-72/UL 60335-2-72, CSA C22.2 No. 10, UL 558, UL 561, UL 583);
• wet and dry vacuum cleaners, including power brush, for COMMERCIAL USE (CSA C22.2 No. 60335-2-69/UL 60335-2-69, CSA C22.2 No. 243/UL 1017);
• hand-held and transportable motor-operated electric TOOLS (CSA/UL 60745 series, CSA 61029 series, CSA C22.2 No. 71.2, UL 987, CSA/UL 62841 series).
• machines designed for use in corrosive or explosive environments (dust, vapour or gas);
• machines designed for picking up hazardous dusts (as defined in IEC 60335-2-69), inflammable substances, or glowing particles;
• machines designed to handle hazardous solvents, such as flammable or explosive liquids;

NOTE 102 Attention is drawn to the fact that in many countries, additional requirements on the safe use of the equipment covered can be specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities.
