Insulation aging measured by shearing modulus

Insulation aging measured by shearing modulus

A NEW METHOD is described for determining the effect of thermal aging on the shearing modulus of flexible sheet insulations by nondestructive tests using a torsion pendulum technique. The test sample consists of a 12-inch length of the material under test, clamped between two pairs of inertia bars o...

Zusammenfassung:A NEW METHOD is described for determining the effect of thermal aging on the shearing modulus of flexible sheet insulations by nondestructive tests using a torsion pendulum technique. The test sample consists of a 12-inch length of the material under test, clamped between two pairs of inertia bars of different weight and inertia.
