HexArmor products with IR-X Impact Guards are tested using the ASTM D2632-01 Resilience by Vertical Rebound test method.
The ASTM D2632-01 "covers the determination of impact resilience of solid rubber from measurement of the vertical rebound of a dropped mass." HexArmor has modified the ASTM D2632-01 test method so that a complete material composition is used on each sample specimen (i.e.: TPR + foam + lining) rather than isolated materials (TPR by itself) so that a more relevant data set is able to be evaluated. The results are given a resilience value which is "determined as a ratio of rebound height to drop height of a metal plunger of prescribed mass and shape which is allowed to fall on a rubber specimen." The ASTM method measures the amount of energy transferred through impact.
