(Test Method)Standard Test Method for Basic Functional Stability of a Mechanical Pump Dispenser
Standard Test Method for Basic Functional Stability of a Mechanical Pump Dispenser
SIGNIFICANCE AND USE
This test method is used for determining the accelerated usage of a mechanical pump dispenser for consumer usage.
SCOPE
1.1 This test method covers the determination of the basic functional stability of a mechanical pump dispenser with a product.
1.2 This test method covers accelerated usage evaluations of mechanical pump dispensers (spray or flow types) with a 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. Specific precautions are given in Section 5.
