1、Designation: D 6536 00 (Reapproved 2005)Standard Test Method forMeasuring the Dip Tube Length of a Mechanical PumpDispenser1This standard is issued under the fixed designation D 6536; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,
2、 the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the measurement technique fora dip tube of a mechanical pump dispenser.1.2 The v
3、alues stated in both inch-pound and SI units are tobe regarded separately as the standard.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 and health practic
4、es and determine the applica-bility of regulatory limitations prior to use.2. Significance and Use2.1 This test method is to be used to measure the length ofa specified dip tube from the bottom of the sealing surface tothe end of the dip tube in a mechanical pump dispenser.2.2 This test method is to
5、 be used to measure the exposedlength of a specified dip tube of a mechanical pump dispenser.3. Apparatus3.1 Thin Metal Ruler, with minimum gradients of 1 mm or116 in., or both, along with a zero index at the end of the ruler.3.2 Calipers.4.

9、e ruler.4.7 Measure the exposed length of the dip tube to within afull millimetre or116 in. length.4.8 Record the length measured in 5.1.5. Report5.1 Report the following information:5.1.1 Type of mechanical pump dispenser,5.1.2 Dip tube length measured, and5.1.3 Method used.6. Precision and Bias6.1
10、 PrecisionThe precision of this test method is within arange of plus or minus 1 mm or116 in. from the specifiedlength depending on the unit of measure used: millimetres orinches. An examination of the results of dip tube lengthmeasurements from _ technicians in one lab found that tenpumps measured u
11、nder Test Method “A” had a range in lengthspecified from _ in. long. Data is currently being gathered.6.2 BiasThis test method has no bias because an acceptedreference or referee value is not available.1This test method is under the jurisdiction of ASTM Committee D10 onPackaging and is the direct re
