Abstract:

A round robin experimental program was conducted to establish the applicability, accuracy, and reliability of the NASL gas chromatographic method for detecting volatile siloxane vapors which are evolved from dimethylsiloxane type insulating materials maintained at elevated temperatures for extended periods. Studies were conducted with commercially prepared siloxane-free test specimens which were contaminated in bulk and on surface with dimethylsiloxane type polymers. Results of the gas chromatographic studies, which are capable of detecting as low as 0.6 microgram cyclic hexamethyltrisiloxane vapors, are correlated with actual brush wear measurements in totally enclosed experimental D.C. motors.
