1、Designation: D4333/D4333M 05 (Reapproved 2010)1Standard Test Method for theCompatibility 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 o
2、f revision, 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.1NOTEUnits information was corrected editorially in March 2011.1. Scope1.1 This test method covers testing
3、 of the components ofmechanical pump dispensers (spray or flow types) for compat-ibility with products.1.2 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 u
4、sed independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard may involve hazardous materials, opera-tions, and equipment. This standard does not purport toaddress all of the safety concerns, if any, associated with itsuse. It i
5、s the responsibility of the user of this standard toconsult and establish appropriate safety and health practicesand determine the applicability of regulatory limitations priorto use.2. Significance and Use2.1 This test method identifies the compatibility of themechanical pump dispenser components w
6、ith consumer-typeproducts.3. Apparatus3.1 Balance, accurate to 1 mg.3.2 Micrometers, or calipers or other appropriate instru-ments, capable of measuring dimensions of test specimens to0.025 mm 0.001 in.3.3 Glass Containers, with covers, suitable for immersingtest specimens in test products.3.4 Oven,
7、 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 foreach part tested with each product involved at each testcondition.4.2 At least three individual components are used as con-tr
8、ols 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 least 4 h prior to testing. If test specimen conditioning is notpossible, the environmental conditioning of the test specimenst
9、ested 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 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 Dime

Measure the thickness or overalllength of the part to the nearest 0.025 mm 0.001 in. of eachcomponent depending on which of these dimensions are mostimportant (for example, thickness for a g
11、asket 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 data is reportedas a mean value of the dimension for the components measuredfor that particular part.6.1.2 Maint

Label thestorage container of these test specimens as control.6.1.3 Place the test specimens in appropriate containers forthe solutions being
