Summary of ISTA 1D Package Integrity Testing

ISTA 1D is an integrity test that covers the testing of individual packaged products weighing 150 pounds (68 kg) or more when prepared for shipment. The test procedure calls for a battery of tests including:

  • Atmospheric Measurement Test Block-Temperature and Humidity.
  • Compression Conditioning Block- Compression.
