Title:Method for Determining Relative Specific Gravity Polytetrafluoroethylene Tubing
Issuing Committee:G-3, Aerospace Couplings, Fittings, Hose, Tubing Assemblies
Scope: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 (see 2.3).【英文标准名称】:Measuringrelaysandprotectionequipment-Part22-1:Electricaldisturbancetests-1MHzburstimmunitytest
