ISTA 1H Package Testing

ISTA 1H testing determines the integrity of a packaged product weighing more than 150lbs. As an ISTA and ISO 17025 certified lab, we realize the importance of transport integrity testing. Meeting the ISTA 1H integrity requirements can be difficult. We understand the challenges and guide companies through the process.

When packages do not meet the requirements, we assist with finding solutions. Keystone Compliance provides constant communication throughout the test process. Our pricing is competitive and we offer volume discounts.

Summary of ISTA 1H Package Testing

ISTA 1H is a package testing standard that applies to packaged products that weigh over 150 lbs. (68 KG) when prepared for shipment. The test sequence for ISTA 1H includes random vibration, drop or impact shock and rotational drop impact tests.

The ISTA 1H standard provides the following suggestions:

  • To use fixed displacement vibration instead of random vibration, use ISTA Test Procedure 1B and not 1H.
  • For packaged-products where a minimum compression value should be tested, use ISTA Test Procedure 1D.
  • For packaged-products intended for international distribution, consider ISTA Partial-Simulation Performance Test Procedure 2B.
  • For unitized loads, conduct ISTA 1E and not ISTA 1H. A unitized load is defined as one or more products or packaged-products usually on a skid or pallet, but always secured together or restrained for distribution as a single load.

The chart below is from the standard and provides more guidance on the testing procedure and requirements:
