ASTM D6654-01

Standard Test Method for Basic Storage Stability of a Mechanical Pump Dispenser

SCOPE
1.1 This test method covers the determination of the basic storage stability of a mechanical pump dispenser with a consumer-type product.
1.2 This test method covers an evaluation of the weight lost during storage of mechanical pump dispensers (spray or flow types) with a consumer-type product.
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 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
