Abstract
This test method covers the procedures for determining the peak force-to-actuate of a mechanical pump dispenser. The apparatus required to perform the tests include a motorized compression tester or custom force-to-action machine, a device that can display the resulting force, and a means to rigidly hold the mechanical pump dispenser during testing. Appropriate machine operating and substance handling should be taken and calibration should be performed on the equipment before testing the clean, dry, and unused pump dispensers.
Scope
1.1 This practice covers the determination of the peak force-to-actuate, sometimes called force-to-actuate (FTA), of a mechanical pump dispenser.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 5.
1.4 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.
