A new ASTM standard tests the potential of pressurized aerosol product to be accidentally inhaled and aspirated by anyone near the spraying. Aspiration can potentially cause lung damage.

The standard (D7952, Test Method for Measuring Aspiration Potential of Aerosol Products) tests spray pattern and aerosol deposition rate.
This test method was developed to determine whether pressurized aerosol spray products containing petroleum distillates present an aspiration risk and require hazard labeling, according to ASTM member Woodhall Stopford, assistant professor at Duke University Medical Center.

Stopford says that paints, varnishes, stains and lubricants are among the products dispensed from pressurized aerosol containers. The new standard could help manufacturers, regulatory bodies, and laboratories to determine whether or not a product is appropriately labeled and whether childproof caps are needed.

Subcommittee D01.57 on Artist Paints and Related Materials developed D7952. Plans are underway to conduct an inter-laboratory study for the standard within the next two years.
