Significance and Use
This practice can be used to compare spray patterns of different pump dispensers and of different products.
Spray patterns from pump dispensers will vary greatly with the design of the actuator and the nature of the liquid. Liquids with differing physical properties will not necessarily yield the same spray pattern when sprayed from the same actuator. Likewise, actuators of different designs will yield spray patterns distinct from each other when the same liquid is used.
1.1 This practice covers the determination of spray patterns from pump dispensers.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
