Summary of ISTA 1G Transit Compliance Testing

The ISTA 1G transit testing procedure is designed for individual packaged products weighing 150 lb or less. The 150-pound limit considers the weight of the product when prepared for shipment. Only individually-packaged products should 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.

When testing is properly applied, the ISTA procedures will provide benefits such as:

  • Shortened package development time and confidence in product launch
  • Protection of products and profits with reduced damage and product lost
  • Economically balanced distribution costs

More specifically, ISTA 1G package integrity testing can be used to evaluate the performance of a packaged product. The test standard can also be used to compare relative performance of package and product design alternatives.

ISTA 1G Package Laboratory Testing Procedures

The simulation integrity performance test includes atmospheric preconditioning, vibration, and shock. The conditioning is a 12-hour ambient soak. The vibration testing is random vibration. Shock testing can be performed either by:

  • Drop testing
  • Inclined impact testing
  • Horizontal impact testing

It is up to the customer to determine the method of choice.

During vibration integrity testing, the package is placed on four different faces. The test duration for each face is 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.

Only one test sample is required for this test method.

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