1、Designation:D4041/D4041M05(Reapproved 2017)Standard Practice forDetermining Spray Patterns of Mechanical PumpDispensers1This standard is issued under the fixed designation D4041/D4041M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,
2、the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers the determination of spray patternsfrom pump dispensers.1.2 The values stated in either SI
3、 units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does no
4、t purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.4 This international standard was develop

7、pump dispensers will vary greatlywith the design of the actuator and the nature of the liquid.Liquids with differing physical properties will not necessarilyyield the same spray pattern when sprayed from the sameactuator.Likewise,actuators of different designs will yieldspray patterns distinct from
