(Test Method)Standard Test Method for Determining Product Leakage from a Package with a Mechanical Pump Dispenser
Standard Test Method for Determining Product Leakage from a Package with a Mechanical Pump Dispenser
ABSTRACT
This test method covers the evaluation of the sealing ability of a mechanical pump dispenser when packaging is held under vacuum and evaluation of the actual seal between the pump dispenser and the neck container/closure integrity. Apparatus for this test method include a vacuum chamber capable of handling pressure within the prescribed range and absorbent paper. Test specimens should be collected and conditioned according to the requirements. Procedures include a product leakage test without vibration testing of a mechanical pump dispenser package and a product leakage test with vibration testing of a mechanical pump dispenser package.
SCOPE
1.1 This test method covers the evaluation of the ability of a pump dispenser to seal when the packaging is held under vacuum. Furthermore, it evaluates the seal between the pump dispenser and the neck container/closure integrity.
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.
See 4.3 for a specific warning statement.
