SAE ARP1153A – Method for Determining Relative Specific Gravity Polytetrafluoroethylene Tubing

This document describes a method for determining the specific gravity of tubing fabricated from polytetrafluoroethylene after a controlled heating and cooling cycle. The specific gravity obtained by this method is a measure of relative molecular weight of the resin. The measure termed relative specific gravity (RSG) increases with decreasing molecular weight.
