ISTA 3B Package Testing

ISTA 3B determines the integrity of less-than-truckload packages in transit. As an ISTA and ISO 17025 certified lab, we realize the importance of ISTA 3B transit testing. Meeting the ISTA 3B requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone Compliance’s accurate test reports are delivered quickly. We are in constant communication throughout the test process. When packages do not meet the requirements, we assist with finding solutions. Lastly, our pricing is competitive and we offer volume discounts.

Summary of ISTA 3B Integrity Testing

ISTA 3B testing is a general simulation test for packaged-products shipped through a motor carrier (truck) delivery system. Different types of packaged-products, often from different shippers and intended for different ultimate destinations, are mixed in the same load.  This type of shipment is called LTL (Less-Than-Truckload).  Procedure 3B is appropriate for four different types of packages commonly distributed in LTL shipments as described below.

Package Types:

  • Standard, 200lb (91 kg) or less, including elongated and flat packages.
  • Standard, over 200lb (91 kg), including elongated and flat packages.
  • Cylindrical, including elongated cylinders.
  • Palletized or Skidded-Individual container, bulk container, or unitized load on or incorporating a base or platform which allows the entry or life truck forks.

Definitions:

Elongated Package or Cylinder

  • A standard or Cylinder package where the longest dimension is 36 in (910 mm) or greater and
  • Both of the packages’ other dimensions (or the cylinders diameter) are each 20 percent or less of the longest dimension.
  • Volume is 800 in3 (13,000 cm3) or greater.

Non-Rigid Container

  • Any Standard (regardless of weight) or Palletized or Skidded container where the outer package may offer insufficient protection from concentrated low-level impacts or
  • The design has large unsupported spans of outer packaging material or
  • The outer package utilizes a stretch-or shrink-wrap design, uses a think-flute or light grade corrugated board, uses a paper wrap or similar lightweight material only, etc. or
  • The outer package wall is in direct contact with the product.

The chart below is an ISTA 3B test overview that provides the standard and more guidance on the testing procedure and requirements for package validation:
