ASTM D6535/D6535M-18

Standard Practice for Determining the Dip Tube Length of a Mechanical Pump Dispenser

SIGNIFICANCE AND USE
2.1 This practice is to be used to determine the length of a dip tube of a mechanical pump dispenser that extends to the bottom-corner of a container.  
2.2 This practice is to be used to determine the length of a dip tube of a mechanical pump dispenser that extends to the bottom-center of a container.
SCOPE
1.1 This practice covers the determination 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 each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two 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 responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Place the zero-index end of the ruler into the container as shown in Fig. 1.
4.2 Turn the ruler so that the side of the ruler reaches as far into the bottom-corner of the container as possible.
NOTE 2—If the cross-sectional area of the container is not round, position the ruler into the farthest bottom-corner of the container.
4.3 Adjust the ruler so that it is positioned through the center axis of the container opening.
