CSA Group Oil/Gas-Fired Commercial/Industrial Pressure Washers and Steam Cleaners CAN/CSA-B140.11-M89 (R2014)

1.1 This Standard covers the performance, construction, testing, marking, installation, operation, and servicing of com plete commercial/industria l pressure washers and steam cleaners that are either gas-fired or oil-fired. 1.2 The Standard applies to (a) complete machines comprising a continuous coil-type heating system, with no space for steam accumulation, in which the solution is heated to a temperature below the saturation temperature for the pressure in the coil and intended to discharge droplets of hot solution 100°C (212°F) or lower from each cleaning nozzle at high velocity; (b) machines intended to discharge only the cleaning solution and machines intended to discharge cleaning solution or rinse water as required by the operator; (c) machines that may be portable or installed as stationary equipment; (d) machines that are manually controlled from the machine to supply the demand at the cleaning nozzle(s) and machines that are automatically controlled in accordance with the demand at the cleaning nozzle(s); (e) machines that supply one or more cleaning nozzles and are primarily intended for cleaning or surface-treating purposes; (f) machines driven by electric motors, internal combustion engines, or other prime movers. 1.3 Clauses 1 to 8 apply to both oil- and gas-fired machines. Clause 9 covers additional requirements for gas-fired machines and Clause 10 covers additional requirements for oil-fired machines. 1.4 Devices or products that comply with these requirements shall not be acceptable if, when examined and tested, they are f ound to have additional features that impair the results contemplated by the requirements. 1.5 The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
