The first test sequence for ISTA 1C includes atmospheric conditioning. The objective is to have the unit to be tested at ambient room temperature.

The next test step is compression testing. The amount of compression is based on the size and weight of the package being tested.

Vibration testing is included. The vibration can either be fixed displacement or random.

Shock testing is the final test. It involves drop testing, incline impact testing or horizontal impact testing.

The customer can select the method and only one method is tested. The test protocol is used to simulate the distribution channel so it is important to consider the specific distribution system that your company utilizes.
