SAE ARP4961

This SAE Aerospace Recommended Practice (ARP) establishes procedures for estimating the weight of parts, weighing actual parts at time of manufacture and maintaining and collecting the weight data.

This document establishes the basic rules to estimate the weights of the parts by determining the volume from geometry of the part(s) with consistent degree of accuracy; to obtain the actual weight of the parts; and to store, transfer, and update the information pertinent to the weights.
