1、Designation: D6536/D6536M 00 (Reapproved 2010)1D6536/D6536M 18Standard Test Method Practice forMeasuring the Dip Tube Length of a Mechanical PumpDispenser1This standard is issued under the fixed designation D6536/D6536M; the number immediately following the designation indicates theyear of original
2、adoption or, in the case of 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.1 NOTEUnits information was editorially revised in December 2010.1. Scope1.1 Thi
3、s test method practice covers the measurement technique for a dip tube of a mechanical pump dispenser.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be
4、used independently of the other. Combining values from thetwo 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 responsibilityof the user of this standard to establish appropria
5、te safety safety, health, and healthenvironmental practices and determine theapplicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for the
6、 Development of International Standards, Guides and Recommendations issuedby the World Trade Organization Technical Barriers to Trade (TBT) Committee.2. Significance and Use2.1 This test method practice is to be used to measure the length of a specified dip tube from the bottom of the sealing surfac
7、eto the end of the dip tube in a mechanical pump dispenser.2.2 This test method practice is to be used to measure the exposed length of a specified dip tube of a mechanical pump dispenser.3. Apparatus3.1 Thin Metal Ruler, with minimum gradients of 1 mm or 116 in., or both, along with a zero index at
8、 the end of the ruler.3.2 Calipers.4. ProcedureTEST METHOD PRACTICE “A”MEASUREMENT OF OVERALL DIP TUBE LENGTHNOTE 1This test method practice is used when the exposed sealing surface of the mechanical pump dispenser is large enough to measure from.4.1 While holding the mechanical pump dispenser with
9、its axis in a horizontal plane, place the zero index end of the ruler againstthe bottom of the seal surface. Fig. 1dimension “X.”4.2 If needed, straighten the dip tube out so that it is parallel with the length of the ruler.4.3 Measure the overall length of the dip tube to within a full millimetre o
10、r 116 in. length.4.4 Record the length measured in 5.1.TEST METHOD PRACTICE “B”MEASUREMENT OF EXPOSED DIP TUBE LENGTHNOTE 2This test method practice is used in all applications.4.5 While holding the mechanical pump dispenser with its axis in a horizontal plane, place the zero index end of the ruler
