Five Steps to Properly Calibrate Your Torque Analyzer
As many packaging engineers and operators are new to this field, we have developed this page to share information about ISBT, ASTM and other torque testing standards available today.
ASTM International
ASTM International is the globally recognized leader in the development and delivery of international voluntary consensus standards. Standards will often include terminology, practices, test methods, specifications, guides, and classifications (including dimensions). This work specifically includes:
1) Defining materials and processes that consider both item and consumer impact; the result being a package and packaged product that are acceptable for delivery,
2) Generating closely related shipping systems design criteria,
3) Developing materials handling standards related to distribution, including measurement of the packaging environment,
4) Assessing the suitability of packaging related standards through round-robin laboratory evaluations, quantitative testing and instrumentation applications, and,
5) Establishing standards on reuse, recycling and disposal of materials related to packaging.
Efforts involving tests on materials where basic research is addressed within other committees shall be closely coordinated with those relevant ASTM committees. In the process of standards development, recognition shall be made of related national and international standards with the encouragement of full participation in those activities.
Standards under the jurisdiction of D10
Each main committee in ASTM International is composed of subcommittees that address specific segments within the general subject area covered by the technical committee. The subcommittee addressing closure integrity questions is Committee D10.32 on Consumer, Pharmaceutical and Medical Packaging (formerly D10.31 on Child Resistant Packaging and Closure Systems).
Update:
In 2016, ASTM D10.32 has merged into F02. There is a new sub-committee: F02.25 responsible for rigid closure related standards.
