(Test Method)Standard Test Method for Measuring Aspiration Potential of Aerosol Products
Standard Test Method for Measuring Aspiration Potential of Aerosol Products
SIGNIFICANCE AND USE
4.1 This test method provides a means of measuring whether or not an aerosol product may present an aspiration risk if a dispensed aerosol gets into one’s mouth.
4.2 The degree of risk for aspiration of an aerosol depends both on spray pattern as well as aerosol deposition rate.2
4.3 This test method will be used to determine the need for child-resistant packaging of aerosol products.
SCOPE
1.1 This test method covers a small-scale laboratory procedure to determine the aspiration potential of aerosol products by determining spray pattern and aerosol deposition rates.
1.2 This test method has been developed to address a need to identify which aerosol products may present an aspiration risk such that special labeling and/or child-resistant packaging would be appropriate. Studies based on this method may allow the development of a practice to identify such aerosol products.
1.3 Although this method may be useful for testing non-pressurized aerosol products, its development has been limited to testing pressurized aerosols.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 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.
