The ASTM D6654-2018 standard is used to assess the Basic Stability of mechanical pump dispensers under storage conditions. This practical approach involves determining the Stability of pump dispensers in different storage environments, with a focus on assessing weight loss during storage. The standard applies to products for personal care, household, pesticides, food, automotive and institutional use, but excludes pharmaceuticals and cosmetics. The standard does not cover all safety issues. Users are required to comply with relevant safety and environment codes and determine applicable regulations.
