Package Testing Q&A

Asked March 9th, 2010
This is a difficult one in that there are some test methods you could use for these containers, but none of them will have been validated by ASTM because they are only guidance documents. The test is a pressure differential test, which is performed by internally pressurizing the container using water. You can reference section 12 of ASTM D4919 or Title 49 CFR 178.605 to determine how the test is performed. This should allow you to qualify the bottles for shipments.
In regard to the test method validation, perhaps you could use a torque setting that is less than your specified torque range to show that the samples will fail if not torqued properly.
You could also perform the test using vacuum but it would require the use of a vacuum chamber large enough to accommodate a 20 L carboy. Again, the only way to validate this methodology would be to use the torque spec and check bottles that have been improperly torqued.
