ASTM D6535-00

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

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.

Designation:D6535–00
Standard Test Method for
Determining the Dip Tube Length of a Mechanical Pump
Dispenser
This standard is issued under the fixed designation D 6535; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. 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.
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 appro-
priate safety and health practices and determine the applica-
bility of regulatory limitations prior to use.
2. Significance and Use
2.1 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.
2.2 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.
3. Apparatus
3.1 Thin Metal Ruler, with minimum gradients of one
millimeter and/or ⁄16 in. along with a zero index at the end of
the ruler.

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.
