BS M 56 – Methods for determination of density and relative density of polytetrafluoroethylene (PTFE) tubing for aerospace applications

Specifies three methods for the determination of the density and relative density of PTFE tubing used in the manufacture of medium and high pressure hose assemblies for aerospace applications: 1. Density gradient column method without a preconditioning heating and cooling cycle. 2. Water displacement method. 3. Density gradient column method with a preconditioning heating and cooling cycle.
