The chief factors considered in ascer-taining the condition of a triple valvewith this rack are: (1) Whether the quiring repairs that are \fter observing the condition of triplevalves, or the workmanship that has beendone on triple valves, that could still bepassed over a standard rack and meet thespecified requirements so far as thestandard code of tests was concerned, it.
