Changes to ISTA 3A for Packages Containing Liquids

ISTA recently made changes to its 3A test procedure with the addition of a leak test for packaged products which contain liquids. The purpose of the change, published in March, is to “evaluate the closure system’s ability to contain the liquid after all other 3A testing elements have been completed.”

The leakage test requires the product package to be removed from its shipping box, placed on its side (ensuring that the liquid product is in contact with the closure and challenging the closure’s ability to contain the liquid product in the package), and inspected for leaking after an 8-hour period.

New guidelines in the test procedure also recommend performing liquid-leakage tests on two or more packaged product samples, but you are encouraged to perform the procedure five or more times using new samples with each test to improve statistical significance for all package types.

Anecto are accredited to conduct testing to ISTA 3A, along with a full range of other transportation and packaging tests. Please contact us if you have an enquiry.
