ASTM D4336-18
(Practice)Standard Practice for Determination of the Output Per Stroke of a Mechanical Pump Dispenser
Standard Practice for Determination of the Output Per Stroke of a Mechanical Pump Dispenser
SIGNIFICANCE AND USE
3.1 This practice can be used to compare the output per stroke of different pump dispensers for the purpose of establishing dosage and use instructions for products of consumer usage.
3.2 This practice is suitable for establishing specifications for both the pump dispenser and the final package.
SCOPE
1.1 This practice covers the measurement of the mean quantity-by-weight of liquids dispensed from a mechanical pump dispenser (spray or flow type) with a consumer-type product on each actuation.
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.
