Has ASTM D4169 changed?
Yes. In 2024, ASTM International made several key changes to ASTM D4169. ASTM D4169-23e1 differs from the previous version, ASTM D4169-223, in several ways.
Schedules B and C, which describe static and dynamic compression testing, were updated to reflect new, increased shipping density of freight factors:
- Type 4 shipping unit construction safety factors were removed from Section 11.2 due to lack of use.
- In situations where density is unknown, the recommend default value has change from ten to twelve pounds per foot cubed.
- The “H” input in the top load formula was slightly modified. 108 inches is still considered the default maximum height of a stack in storage or a transit vehicle and is used in situations where the maximum height is unknown. However, if the package is classified as “light and small,” this is reduced to 54 inches, and the package is assumed to be in the top half of the stack.
- The standard definition of a “light and small” package has been changed to packages weighing less than ten pounds (4.53 kilograms), with volume below two cubic feet (0.056 cubic meters).
Additionally, ASTM D4169 now includes a new reference to to ASTM F2825 – Standard Practice for Climatic Stressing of Packaging Systems for Single Parcel Delivery.
Lastly, small minor editorial changes have been made.
