(Practice)Standard Practice for Storage Testing of Aerosol Products
Standard Practice for Storage Testing of Aerosol Products
SIGNIFICANCE AND USE
Aerosol products are subjected to storage tests to ascertain the shelf-life of the complete package, and to evaluate the degree of suitability of the valve and container components for their intended uses.
It is impractical to promulgate a standard procedure for conducting storage tests, since variations will be necessitated by differences in the ultimate objective (for example, the primary interest of one test may be concerned with container suitability or shelf-life of a new product in an existing package, while another test may be concerned with valve evaluation).
It follows that storage testing must be flexible enough to accommodate the small procedural changes required. Thus, this recommended practice will only set forth those principles to be observed in establishing a definite procedure, in order to allow the individual operator the prerogative of adapting these to satisfy his particular requirements.
SCOPE
1.1 This practice covers the storage testing of aerosol products.
1.2 There are two major types of storage tests that may be performed on aerosol products:
1.2.1 Live Storage Tests, where the valves are actuated and the determinations are made at relatively frequent intervals (the purpose being to simulate consumer use of aerosol dispensers), and
1.2.2 Dead Storage Tests, performed to simulate warehouse storage conditions when shelf-life information is sought.
1.3 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.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 4.
