ASTM D3890-01

Standard Test Method for Number of Strokes to Prime a Mechanical Pump Dispenser

SCOPE
1.1 This test method 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 and health practices and determine the applicability of regulatory limitations prior to use.
