(Practice)Standard Practice for Effective Crimping on Outside Crimped Valves of Aerosol Containers (Withdrawn 2023)
Standard Practice for Effective Crimping on Outside Crimped Valves of Aerosol Containers (Withdrawn 2023)
SIGNIFICANCE AND USE
5.1 This practice provides information for the establishment of quality control procedures on filling lines.
SCOPE
1.1 This practice covers the effective crimping on outside crimped valves within the wide parameters of containers and valves available.
1.2 Practices appear in the following order:
Sections
Optical Comparator Practice
4 to 7
Caliper Practice
8 to 12
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.
1.5 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.
WITHDRAWN RATIONALE
This practice covered the effective crimping on outside crimped valves within the wide parameters of containers and valves available.
Formerly under the jurisdiction of Committee D10 on Packaging, this practice was withdrawn in December 2023. This standard is being withdrawn without replacement because the Household and Consumer Products Association (HCPA) offers standards for Aerosol Products.

4. Summary of Test MethodPractice
4.1 This test method practice involves drawing a projected, enlarged profile of the container and valve, then removing the valve
and drawing the projected profile of the container finish. Measuring the resultant void and subtracting the dimensions of the
essentially noncompressed components from this value results in the value representing the compressed thickness of the valve
sealing gasket.

factor of the essentially uncompressed components of the valve) from this value to obtain the thickness of the compressed gasket
