Webthis rating describes incipient deposit forming tendencies. A number of precision programs (5,7) were conducted. The later program (7) showed the reproducibility of the pass-fail procedure to be equal to a rating of 2. In other words, at an average rating of 2 any tube rating within 1 to 3 is considered within the reproducibility of the procedure. WebThe authors examined these and several other measurement techniques for JFTOT heater tubes and found that measurements of total carbon content by combustion were the …
