The Plastic Aerosol Research Group, LLC (PARG) and the Household & Commercial Products Association (HCPA) are seeking comments on PARG’s new method: PARG Method 22.0, “Gasket Compression Non-Destructive Evaluation for Aerosol Products.”  This method details the procedure on how to calculate the minimum percent gasket compression for a non-pressurized clinched container.

Reviewers will have until February 27, 2020 to submit their comments to HCPA regarding the methods. For questions or to request a copy of the test method for review, please contact HCPA’s Aerosol Products Division Staff Executive, Nicholas Georges, at

The final method will be available for purchase on the HCPA website within PARG’s Aerosol Products in Plastic Containers Guide.

PARG’s methods and standards are used by those engaged in the formulation, manufacture or marketing of aerosol products in plastic containers. PARG has developed the Aerosol Products in Plastic Containers Guide as voluntary methods and standards designed to be useful in conducting evaluations to address regulatory requirements and identifying appropriate measurements during the development and manufacturing of aerosol products in plastic containers. The Aerosol Products in Plastic Containers Guide is the result of a collaborative and consensus research and evaluation process from PARG member companies.
