Suggested changes in temperature limits of present standards for stationary contact surfaces

With extensive review of tests made during the past 25 years plus the results of certain self-conducted tests as its basis, the AIEE Standards committee subcommittee on conduction in stationary contact surfaces recommends various changes in the present Standards for permissible temperatures on electric contacts. These recommendations, together with pertinent abstracts of present Standards, are presented herewith for the purpose of obtaining comments and criticism.
