(Test Method)Standard Test Methods for Effective Crimping on Outside Crimped Valves of Aerosol Containers
Standard Test Methods for Effective Crimping on Outside Crimped Valves of Aerosol Containers
SIGNIFICANCE AND USE
This test method provides information for the establishment of quality control procedures on filling lines.
SCOPE
1.1 These test methods cover the effective crimping on outside crimped valves within the wide parameters of containers and valves available.
1.2 The test methods appear in the following order: SectionsOptical Comparator Test Method4 to 7Caliper Test Method8 to 12
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.
