(Test Method)Standard Test Method for Determining the Dip Tube Length of a Mechanical Pump Dispenser
Standard Test Method for Determining the Dip Tube Length of a Mechanical Pump Dispenser
SIGNIFICANCE AND USE
This test method 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.
This test method 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 test method 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 and health practices and determine the applicability of regulatory limitations prior to use.

TEST METHOD “A”—DIP TUBE LENGTH DETERMINATION TO THE BOTTOM-CORNER OF THE
CONTAINER
NOTE 1—This test method is used when the dip tube of a mechanical pump dispenser must extend to the bottom-corner of a container.
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.

gradient, use the larger value (that is, if measurement is 118.5 mm, use 119 mm; or if measurement is 4- ⁄32 in., use 4- ⁄16 in).
4.5 If the dip tube measurement is in millimetres, subtract 1 mm from the measured value. If the dip tube measurement is in
inches, subtract ⁄16 in. from the measured value.
4.6 Record the net value (original value minus 1 mm or ⁄16 in.).
4.7 To verify the new dip tube specification, prepare a sample mechanical pump dispenser with the newly-specified dip tube
length.
4.8 Secure the mechanical pump dispenser to the container.
4.9 Verify that the end of the dip tube is not closed-off by the bottom or side of the container.
This test method is under the jurisdiction of ASTM Committee D10 on Packaging and is the direct responsibility of Subcommittee D10.33 on Mechanical Dispensers.
