The age limit of a nonstandard high pressure boiler installed before August 5, 1974, is 30 years. After a thorough internal and external inspection and a hydrostatic pressure test of one and one-half times the allowable working pressure, held for a minimum of 30 minutes, during which time no distress or leakage develops, a boiler with other than a lap-riveted longitudinal joint may be continued in operation without a reduction in working pressure.
