37、on systems, corrosion protection, and electrical and mechanical testing for severe-duty TEFC squirrel cage polyphase induction motors, up to and including 370 kW (500 hp), for petroleum and chemical industry application. Many of the specified materials and components in this standard stem from exper
38、ience with severely corrosive atmospheres and the necessity for safe, quiet, reliable, premium efficiency motors. 2.
