Standard Terminology Relating to Mechanical Pump Dispensers (Withdrawn 2016)
SCOPE
1.1 The terms found in this terminology relate to the nomenclature used in the packaging industry.
1.2 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.
WITHDRAWN RATIONALE
The definitions found in this terminology related to the nomenclature used in the packaging industry.
Formerly under the jurisdiction of Committee D10 on Packaging, this terminology was withdrawn in January 2016 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
