Oil/gas-fired commercial/industrial pressure washers and steam cleaners

This Standard covers the performance, construc-

tion, testing, marking, installation, operation, and

servicing of complete commerciaVindustria1 pres-

sure 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 (212OF) or lower from

each cleaning nozzle at high velocity;

(b) machines intended to discharge only the

cleaning solution and machines intended to dis-

charge 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 con-

trolled in accordance with thedemand at the cleaning

nozz I e(s); 

(e) machines that supply one or more cleaning

nozzles and are primarily intended for cleaning or

su rface-treati

 

ng 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 9coversadditional requirements

for gas-fired machines and Clause 10 covers addi-

tional requirements for oil-fired machines.

 

1.4

Devices or products that comply with these require-

mentsshall not be acceptable if, when examined and

tested, they are found to have additional features

that impair the results contemplated by the require-

ments.
