Canadian Standards Association (operating as “CSA Group”), under whose auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for- profit, nonstatutory, voluntary membership association engaged in standards development and certification activities.
CSA Group standards reflect a national consensus of producers and users — including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment.
Individuals, companies, and associations across Canada indicate their support for CSA Group’s standards development by
volunteering their time and skills to Committee work and supporting CSA Group’s objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSA Group’s total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSA Group’s standards development activities.
CSA Group offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, CSA Group regularly and continually audits and inspects products that bear the
CSA Group Mark.
In addition to its head office and laboratory complex in Toronto, CSA Group has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Since 1919, CSA Group has developed the necessary expertise to meet its corporate mission: CSA Group is an independent service
organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification and related services to meet national and international needs.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES – SAFETY –
Part 2-72: Particular requirements for floor treatment machines with or without traction drive, for commercial use
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of powered ride-on and powered WALK-BEHIND MACHINES
intended for commercial indoor or outdoor use for the following applications:
sweeping,
scrubbing,
wet or dry pick-up,
polishing,
application of wax, sealing products and powder based detergents,
shampooing
of floors with an artificial surface.
Their cleaning motion is more linear than lateral or periodic.
NOTE 101 By contrast, the cleaning motion of machines covered by IEC 60335-2-67 is more lateral or periodic than linear.
NOTE 102 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;
all uses other than normal housekeeping purposes.
They may be equipped with a TRACTION DRIVE system. The following power systems are covered:
internal combustion engines,
mains powered motors up to a RATED VOLTAGE of 250 V for single-phase appliances and 480 V for other appliances,
battery powered motors.
