Amazon Type A (17)


ISTA 1E is an integrity test for unitized loads of the same institutional or retail packaged-products. The standard defines a unitized load 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. Examples would be a stretch-wrapped pallet load of individual containers, a single non-packaged machine banded to a pallet and a pallet with corrugated tray, tube and a cap.

For ISTA 1E, the shipper must determine the following prior to testing:

  • What constitutes damage to the product and
  • What damage tolerance level is allowable, if any, and
  • The correct methodology to determine product condition at the conclusion of the tests and
  • The acceptable package condition at the conclusion of the test.

The test sequences for ISTA Procedure 1E include the following tests:

  • Vibration Test Block.
  • Random.
  • Shock Test Block-Impact.
  • Shock Test Block-Rotational Edge Drop.

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