Abstract:

The dry and wet loss factors were determined by measurements made at 1000 kilocycles, in compliance with paragraph two of referencec, paragraph 6-1 of reference d, and in accordance with A.S.T.M. Standards on Testing Electrical Insulating Materials of December 1941. The wet loss factor was measured after the samples had been immersed in distilled water for 48 hours. The modulus of rupture test was made on a Standard Southwalk Testing machine.
