ASTM D4334-18

Standard Practice for Determination of the Dip Tube Retention of a Mechanical Pump Dispenser

SIGNIFICANCE AND USE
2.1 This practice may be used to establish performance specifications.  
2.2 This practice may be used as a quality control assessment.
SCOPE
1.1 This practice covers the determination of the force necessary to separate the dip tube from the body of a mechanical pump dispenser (spray or flow types).  
1.2 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.  
1.3 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

1. Scope
1.1 This test method practice covers the determination of the force necessary to separate the dip tube from the body of a
mechanical pump dispenser (spray or flow types).
1.2 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 consult and establish appropriate safety safety, health, and healthenvironmental practices and
determine the applicability of regulatory limitations prior to use.
1.3 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.
2. Significance and Use
2.1 This test method practice may be used to establish performance specifications.
2.2 This test method practice may be used as a quality control assessment.
3. Apparatus
3.1 Test Stand—The test apparatus shall be capable of applying a smoothly increasing load to the test specimen until the dip
tube is separated from the body of the mechanical pump dispenser.
NOTE 1—The condition of 3.1 is fulfilled by most motor driven tensile strength testers with a constant rate of elongation.
NOTE 2—The test stand should be equipped with a maximum force indicator.
3.2 Clamps:
3.2.1 Fixture, to secure the upper part of the mechanical pump dispenser. The fixture shall secure the dispenser in such a way
that there is no slippage between it and the test specimen.
3.2.2 Clamp, to secure the dip tube. The clamp shall hold the dip tube in such a way that there is no slippage between the dip
tube and the clamp.
3.2.3 Arrange the fixturing so that the tube is maintained in a position parallel to, and within the colinear plane of, the applied
force.
3.3 Scale, graduated in either millimetres or inches.
4. Sampling
4.1 Select an appropriate number of dry, unused pump dispensers at random for precision and accuracy desired. Use of 10 test
specimens is recommended, but a minimum of three is acceptable.
5. Conditioning
5.1 If possible, condition the test specimens at 23 6 3°C (73 6 5.4°F) for not less than 4 h. If the test specimens are not
conditioned at the recommended temperature, this should be noted in the test report discussed in 7.1.

5.2 Test pumps should be tested no sooner than 24 h after assembly when possible. If the pumps are not conditioned at the
recommended time, this should be noted in the test report discussed in 7.1.
6. Procedure
6.1 Attach fixtures and clamp to the test standard in accordance with the manufacturer’s instructions and in a manner consistent
with the pump’s geometry.
6.2 Insert the dip tube securely into the clamp and tighten to prevent slippage.
6.3 Adjust the test stand so that there is 25 mm of exposed dip tube length.
NOTE 3—At this time, there should be a zero reading on the force gage.
6.4 Operate the test stand at 250 mm (10 in.)/min until the dip tube has separated either from the pump dispenser, broken,
slipped from the jaws, or reached the limit of cross-head travel. If the recommended cross-head speed is not used, record cross-head
speed (see 7.1).
6.5 Record the maximum force reading, N (lb).
6.6 Record the mode of failure for each test specimen tested.
