The data from reports of 35 laboratories, comprising more than 2,000 analytical determinations, indicate that the vacuum-fusion method yields accurate r esults for the oxygen contents of plain-carbon steels either aluminum-killed, siliconkilled, or of the rimming type; the aqueous-iodine method yields accurate results for some types of killed steels and low results for other steels; more data, and particularly more concordant data, are necessary to define the accuracy of the other methods
more » ... ed in this cooperative analysis. The vacuum-fusion procedures are reviewed and recommendations given for obtaining optimum results by this method.
