(Practice)Standard Practice for Number of Strokes to Prime a Mechanical Pump Dispenser
Standard Practice for Number of Strokes to Prime a Mechanical Pump Dispenser
SIGNIFICANCE AND USE
2.1 This practice can be used to visually compare priming characteristics of different pump dispensers and different products.
2.2 This practice is suitable for establishing specifications for both the pump dispenser and the final package.
SCOPE
1.1 This practice covers the determination of the number of actuations required to prime a pump dispenser (spray and flow types) with a consumer-type product.
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.

Number of Strokes to Prime a Mechanical Pump Dispenser
This standard is issued under the fixed designation D3890; 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 (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method practice covers the determination of the number of actuations required to prime a pump dispenser (spray
and flow types) with a consumer-type product.
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 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 can be used to visually compare priming characteristics of different pump dispensers and different
products.
2.2 This test method practice is suitable for establishing specifications for both the pump dispenser and the final package.
3. Apparatus
3.1 No apparatus is required, although a mechanical device for actuating the pump dispenser may be used.
4. Sampling
4.1 Select an appropriate number of dry, unused pump dispensers at random for the precision and accuracy desired. A number
of ten test specimens are 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 8.1.
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 8.1.
6. Test Specimens
6.1 For each test specimen, select a container to which the pump dispenser will be attached during the test. Since the dip tube
length affects the number of strokes to prime, the actual bottle of the final package is recommended for testing.
7. Procedure
7.1 Fill each container with the product to be tested at the actual level of the final package target weight.
7.2 Attach the pump dispenser securely to the container. The pump should be in the off, locked, or closed position. Take care
not to actuate the pump dispenser during this step.
NOTE 1—If the actuator is placed onto the pump after the pump has been secured onto the container, then report this additional stroke in the final results
in 8.1.

NOTE 2—If an actuation is required when opening or unlocking the pump, then report this additional actuation in the test report discussed in 8.1.
7.3 If the pump dispenser is equipped with an overcap or locking feature, remove or release the feature to permit the pump
dispenser to be in the operable mode.
7.4 If the pump dispenser has a variable output-per-stroke feature, make an appropriate adjustment to achieve the desired
output-per-stroke at this time. Report this desired dosage in 8.1.
7.5 Actuate the pump dispenser to its fullest extent with smooth, firm, and even pressure. Allow the pump mechanism to fully
