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 also cover portable rechargeable battery-powered high pressure cleaning machines for indoor or outdoor use with rechargeable non-user and user-replaceable batteries; see Appendix B. 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.
