Summary of ISTA 3B Package Integrity Compliance Testing

The ISTA Procedure 3B shipping procedure is designed to test packaged products for less-than-truckload (LTL) shipments. The procedure is a general simulation test for the packaged products shipped through a motor carrier delivery system. These systems process different types of packages from different shippers and the loads are intended for different destinations. This type of shipment is considered LTL.

ISTA’s 3B Procedure addresses four package types. Standard packages are packages that are 200 pounds or less. Flat packages and elongated packages can be considered standard packages. There is also a classification of standard packages for packages over 200 pounds including flat and elongated. Cylindrical packages are included in this procedure. The last type is palletized or skidded.

In situations where a package meets the requirements of both a flat and elongated package, the package should be tested as if it is elongated.

Non-rigid containers are any standard, palletized, or skidded container that meets one of the following criteria.

First, the outer packaging may offer insufficient protection from concentrated low-level impacts.

Another criterion is that the design has large unsupported spans of outer packaging material.

The third possible criteria is the outer packaging utilizes a stretch or shrink-wrap design, uses a thin-flute or light-grade corrugated board, or uses a paper wrap or similar lightweight material only. The last criterion is that the outer package wall is in direct contact with the product.

ISTA 3B Palletized Packaging Testing Procedures

ISTA 3B spells out the specific tests for each type of package. The tests and sequences will vary by package type. Most packages will need to undergo condition, shock testing, and vibration testing. The shock testing can include tip over, free-fall drop, concentrated impact, full rotational drop, concentrated edge impact, incline impact, bridged impact, and drop on a hazard. The vibration testing can include random with a top load and random without a top load.
