|
|
| Some data reported from Ref. 2-20
reported temperatures of 212 F rather than 375 F as in the original Ref. 8 paper. These were assumed to be erroeous. |
| Datum for Sulfuric acid (nitrogen
saturated) at 20% at 375F reported in ref. 5 as 355 mpy, believed to be a
typographical error. Datum for Nitric acid at 30% at 374F
reported in ref. 5 as 94 mpy, believed to be a typographical error. |
