ISTA 4AB Package Testing

As an ISTA and ISO 17025 certified lab, we realize the importance of ISTA 4AB testing. Meeting the ISTA 4AB requirements can be difficult. We understand the challenges and guide companies through the process.

We have a reputation of helping customers achieve their package certifications. Keystone takes a consultative approach throughout the entire test program. We are in constant communication throughout the test process. When packages do not meet the requirements, we assist with finding solutions.

Summary of ISTA 4AB Package Integrity Testing

ISTA 4AB covers testing of 12 different package types, 4 handling types, and 7 types of load-carrying materials or combinations. Any hazard (test) element may be assigned one of three intensities. Program inputs and test plans may be in English or metric units.

The ISTA test sequence is tailored to individual situations with usage of up-to-date and specific hazard profiles and parameters. Unlike Focused Simulation, 4AB does not require the user to make quantitative field measurements and translate those into laboratory tests.  

Measurement-derived test protocols are included as part of the simulation.  Once the item to be shipped and the distribution system, means, and configurations are defined, a test plan is generated without further input.

The tests shall be performed on each test sample in the sequence indicated in the 4AB Test Plan generated.

The chart below is from ISTA 4AB the standard and provides more guidance on the testing procedure and requirements:
