ISTA 1G Package Testing

The ISTA 1G transit testing procedure is designed for packaged products weighing less than 150 pounds. The 150-pound limit considers the weight of the product when prepared for shipment. Individually-packaged products should only be considered. Products on skids or pallets that weigh more than 100 pounds may be tested according to ISTA Test Procedure 1E or ISTA Test Procedure 1H.

The test sequence includes atmospheric preconditioning, vibration and shock. The conditioning is basically a 12-hour ambient soak. The vibration testing is random vibration. The shock testing can be either drop testing, an incline impact test or horizontal impact tests. The customer will determine the method.

Only one test sample is required for this test method.

During vibration testing the package is placed on four different faces. The test durations for each face are called out in the ISTA 1G test procedure. The drop testing involves 10 separate sequences. There is one corner drop and three edge drops. The package is also dropped on each of the six faces of the package.

Included below is a chart with specific information about the test sequences in this procedure:
