CETA’s objective in publishing this standard is to provide a uniform method for testing and rating pressure washers. The movement toward performance standards has becomes a world-wide effort. The use of such standards offers significant advantages. A performance-based standard focuses on desired characteristics of the final product, service or activity, rather than the processes to produce it. (Note: Performance-based standards are also known as objective-based standards).

The goal is to have a standard to evaluate pressure washer specifications used in advertising. CETA certification will not only improve the image of our members but will provide leverage in an industry with increasing competitive pressure.

Why do we need safety standards?

  • Objective: to evaluate pressure washer’s specifications used in advertising material.
  • Requirements for a pressure washer to be CETA certified:
  • The actual measured pressure in the equipment needs to be at least 90% of the advertised pressure.
  • The actual measured flow in the equipment needs to be at least 90% of the advertised flow.
  • In case of Gas engine pressure washers, the engine must operate at 85% of its maximum capacity or less.
  • In case of Electric motor pressure washers, the motor shall not exceed the amperage on the name plate including the service factor while supplying +/-10% of the name plate voltage.
