1、Designation:D4333/D4333M18Standard Practice forCompatibility of Mechanical Pump Dispenser Components1This standard is issued under the fixed designation D4333/D4333M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last re
2、vision.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 testing of the components ofmechanical pump dispensers(spray or flow types)for compat-ibility with products.1
3、.2 The values stated in either SI 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 s
4、tandard.1.3 This standard does not 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to

6、 to Trade(TBT)Committee.2.Significance and Use2.1 This practice identifies the compatibility of the mechani-cal pump dispenser components with consumer-type products.3.Apparatus3.1 Balance,accurate to 1 mg.3.2 Micrometers,orcalipersorotherappropriateinstruments,capable of measuring dimensions of tes
7、t speci-mens to 0.025 mm 0.001 in.3.3 Glass Containers,with covers,suitable for immersingtest specimens in test products.3.4 Oven,with chamber capable of maintaining temperaturewithin 62C 63.6F of the specified test temperatures.4.Test Specimen4.1 At least three individual components should be used
8、foreach part tested with each product involved at each testcondition.4.2 At least three individual components are used as con-trols at each test condition.4.3 Individual unassembled components shall be clean andpreviously unused.5.Conditioning5.1 Condition test specimens at 23 6 3C 73.46 5.4F forat
9、least 4 h prior to testing.If test specimen conditioning is notpossible,the environmental conditioning of the test specimenstested should be included in the report as discussed in 7.1.5.2 Test conditions shall be an elevated temperature of 45 63C 113 6 5.4F and an ambient room temperature of 23 63C
10、73.4 6 5.4F.If a different temperature is used,thisshould be noted in the test report discussed in 7.1.6.Procedure6.1 Dimensional and Weight Changes:6.1.1 Prior to immersion into the product,weigh the partand record as W1(see 7).Measure the thickness or overalllength of the part to the nearest 0.025
11、 mm 0.001 in.of eachcomponent depending on which of these dimensions are mostimportant(for example,thickness for a gasket or liner,andoverall length for a molded component).Optionally,measure adiameter of the part to its nearest 0.025 mm 0.001 in.Reportthe data as initial dimension D1(see 7).This da
12、ta is reportedas a mean value of the dimension for the components measuredfor that particular part.6.1.2 Maintain at least three test specimens as visual com-parison controls.Do not immerse these control test specimensin any solution and store at each test condition.Label thestorage container of the
13、se test specimens as control.6.1.3 Place the test specimens in appropriate containers forthe solutions being used and allow the test specimens to betotally immersed in fresh test product for 7 days in each testcondition.Several test specimens of a given material may beimmersed in the same container
