The flow rate test is used to confirm that the spray valve is operating at the manufacturer's rated flow rate at the specified water pressure. This test would also assist the operator in controlling the water and sewer consumption and reduce the water heating bills.

The cleanability test is used to verify the spray valve's effectiveness at cleaning the plates before they are sent into the dishwashing machine.

1. Scope

1.1 This test method covers the water consumption flow rate and cleanability of prerinse spray valves (here after referred to as spray valves). The food service operator can use this evaluation to select a spray valve and understand its water consumption and cleaning effectiveness.

1.2 The following procedures are included in this test method:

1.2.1 Water consumption (see 10.2).

1.2.2 Cleanability (see 10.3).

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 This test method may involve hazardous materials, operations, and equipment. It does not address all of the potential safety problems associated with its use. It is the responsibility of the users of this test method to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to its use.
