Summary ISTA 1H Transportation Integrity Testing

The ISTA test standard for packaged products over 150 pounds is ISTA Procedure 1H. This test procedure requires the shipper to determine a number or items prior to testing. This includes what constitutes damage to the product. Defining what damage tolerance is allowable if any. How to determine product condition once testing is complete. What an acceptable condition of the packaging will be at the conclusion of transit testing.

Why is package testing so important? Package testing provides valuable insight earlier in the product sales process. By having sufficient packaging, companies will save money through reduced returns. They will also benefit from not having their reputation tarnished by damaged products.

More and more retailers and distributors are requiring package certification.

By completing package testing, sellers can identify better methods of packing. This could include smaller dimensions and less dunnage. This could also include using different materials including recycled materials. The product placement in the package can also be modified to find the best combination.

ISTA 1H Package Integrity Laboratory Testing Procedures

Only one sample is required for this testing. However, ISTA recommends testing five or more samples to ensure accurate results are received. The sample should be the actual untested product and package. If both are not available, substitutes should be as identical as possible.

First, the test procedure includes conditioning to ambient temperature and humidity.

Next, there is also mandatory random vibration and rotational edge drop testing. The shipper also must complete shock testing. Any one of three methods can be used. These methods are drop, incline impact, and horizontal impact. Lastly, a rotational edge drop is performed when specific criteria is met.

Included below is the test sequence for the ISTA 1H shipping tests:
