ASTM F2031-05 (R2014) PDF Download

In order to measure the static spine or stiffness of arrow shafts in the archery business, a standard test method known as ASTM F2031-05 (R2014) is used. The standard offers a consistent nomenclature for arrow shafts and defines and explains the concept of arrow spine.

The test technique calls for the measurement of the arrow spine to be made in inches of deflection using the English system of measurement. This makes it possible for customers and producers to compare and comprehend the spine values of arrow shafts with ease.

This standard's main goal is to establish a common industry standard that enables precise comparisons between various arrow shafts. This helps consumers choose arrows based on their stiffness properties while enabling producers to generate goods that are consistent.
