(Test Method)Test Method for the Compatibility Resistance of Mechanical Pump Dispenser Components
Test Method for the Compatibility Resistance of Mechanical Pump Dispenser Components
SIGNIFICANCE AND USE
This test method identifies the compatibility of the mechanical pump dispenser components with consumer-type products.
SCOPE
1.1 This test method covers testing of the components of mechanical pump dispensers (spray or flow types) for compatibility with consumer-type products.
1.2 This standard may involve hazardous materials, operations, and equipment. 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 to determine the applicability of regulatory limitations prior to use.
