Description / Abstract:
These requirements cover portable, stationary, and fixed
high-pressure cleaning machines in which the discharge line is hand
supported and manipulated, and intended for household, farm, or
commercial/industrial applications.
The electrical products covered by these requirements are
intended for use in ordinary locations and for connection to branch
circuits rated 600 volts or less in accordance with the National
Electrical Code, NFPA 70.
These requirements do not cover:
a) High-pressure water cutting or cleaning products developing
nozzle pressure and flow rates in excess of those for a Type 3
pressure cleaning machine as specified in 2.2.33,
b) Products employing universal motors rated more than 250
volts,
c) Sand blasters or other products using cleaning solutions
containing insoluble particulates,
d) Products that develop steam within a heated vessel or are
connected to an external source of steam, and
e) Carpet cleaners, dishwashers, clothes-washing machines,
water-picks, and other products that are covered under separate
requirements.
A coin-operated product is investigated under these requirements
and under such additional requirements as are applicable to the
product under consideration.
