ASTM D6535-05

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 both inch pound and SI units are to be regarded separately as the standard.
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.

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.
4.10 To specify the exposed dip tube length, measure the
length of the exposed body as per dimension “Y” of Fig. 2 and
subtract from the overall length as specified in 4.6.
NOTE 3—If the container is not transparent, a section of the bottom of
the container may need to be removed so that the position of the end of the
dip tube may be viewed.
