ASTM F2324-13

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Prerinse Spray Valves
This standard is issued under the fixed designation F2324; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method covers the water consumption flow rate and cleanability spray force of prerinse spray valves (here after
referred to as spray valves). valves. The food service operator can use this evaluation to select a prerinse spray valve and
understand its water consumption and cleaning effectiveness.spray force.
1.2 The following procedures are included in this test method:
1.2.1 Water consumption (see 10.2).
1.2.2 Cleanability Spray force test (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.

3.1 Definitions:
3.1.1 cleanability—prerinse spray valve—the effectiveness of the prerinse spray valve to remove soil from the plate before it
is placed in a dishwashing machine.a handheld device containing a release to close mechanism that is used to spray water on
dishes, flatware, etc.
3.1.2 spray force—the amount of force exerted onto the spray disc.
3.1.3 test method—a definitive procedure for the identification, measurement, and evaluation of one or more qualities,
characteristics, or properties of a material, product, system, or service that produces a test result.
3.1.4 uncertainty—measure of systematic and precision errors in specified instrumentation or measure of repeatability of a
reported test result.

4. Summary of Test Method
4.1 The flow rate of the prerinse spray valve is determined at the manufacturer’s specified water pressure measured at a water
pressure of 60 6 2 psi (413.7 6 13.8 kPa) and 60 6 10°F (15.6 6 2.6°C) to verify that the prerinse spray valve is operating at

the manufacturer’s rated flow rate. If the measured flow rate is not within 5 % of the rated flow rate, all further testing ceases and
the manufacturer is contacted. The manufacturer may make appropriate changes or adjustments to the prerinse spray valve.
4.2 The spray valve’s water flow rate is measured at 60 6 1 psi (2.9 6 0.5 kPa) settings at a temperature of 120 6 4°F (49
6 2°C).
