Summary of ISTA 1B Package Testing Compliance
ISTA Procedure 1B package testing evaluates individually packaged products weighing more than 150 pounds. Specifically, the procedure determines how well a package protects its contents from normal transportation hazards.
When applied correctly, ISTA 1B testing helps shorten package development time. In addition, it reduces product damage during distribution while balancing transportation and packaging costs.
The ISTA 1B test sequence includes conditioning, vibration, and several types of shock testing. Together, these tests evaluate package performance throughout the distribution cycle.
Conditioning
The conditioning is to ensure the unit is at ambient temperature. Conditioning and preconditioning are performed to simulate the different environments that a package could encounter throughout the distribution channel.
Vibration
The vibration is a fixed displacement vibration. The shock testing includes drop, incline impact, horizontal impact, or rotational edge drop. Only one shock test method is to be used. Units do not need to be tested for all three methods. The vibration and shock tests are meant to simulate the different hazards that a package could encounter during distribution.
Impact
The drop or impact is to occur on each face or side. The drops are to happen in a certain sequence. Impact testing is to occur on four faces. The rotational edge drop involves lifting one edge three to four inches off the ground. That edge of the box is then reinforced with timber or support. Next, the other edge is raised eight inches. The height that is raised is predetermined by a formula that takes into account the weight of the package.
Lastly, the higher edge is released so that the package drops freely. It is important that it is dropped on a flat and rigid surface.
Why is ISTA 1B Laboratory Testing Important?
What starts as minor shipment damage can turn into a financial nightmare with costs from replacements, added labor, and fading customer loyalty. Uncovering these hidden burdens is essential for bottom-line protection and operational improvements.
Additionally, delivering undamaged products builds trust, reduces complaints, and enhances overall satisfaction, as even minor shipment issues can erode confidence over time.

ISTA 1B Package Testing Procedures
As with ISTA 1A testing, only one test unit is required for ISTA 1B testing.
The ISTA 1B package testing standard contains three sections:
- Overview provides the general knowledge required before going into the testing laboratory.
- Testing presents the specific instructions to do the testing in the laboratory.
- Report indicates what data shall be recorded to submit a test report to ISTA.
The chart below is from the procedure and provides guidance on the testing sequence and requirements:
| Sequence # | Test Category | Test Type | For ISTA Certification |
| 1 | Preconditioning | Temperature and Humidity | Required |
| 2 | Vibration | Fixed Displacement | Required |
| 3 | Shock | Drop | Required |
| Inclined Impact | |||
| Horizontal Impact | |||
| 4 | Shock | Rotational Edge Drop | Required when not testing face 1 |
