ASTM WK92813
Revision of D7136/D7136M-20 Standard Test Method for Measuring the Damage Resistance of a Fiber-Reinforced Polymer Matrix Composite to a Drop-Weight Impact Event
Rationale
This revision addresses a comment from Ed Walters (SpaceX) who noted that the equations in Section 13 do not contain the correct coefficients when using inch-pound units (to address conversion of mass from lbm to slugs and velocity from in/s to ft/s). Section 13 equations are revised and descriptive notes added.
