ISTA 3B

ISTA 3B is a general simulation test for packaged-products shipped through a motor carrier (truck) delivery system, where 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
    • 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 from ISTA 3B the standard and provides more guidance on the testing procedure and requirements:
