Research Report RR:D31-1017

    The precision of test method D7818 is based on an interlaboratory study of WK28572, Standard Test Method for the Enumeration of Proteolytic Bacteria in Fresh (uncured) Hides and Skins, conducted in 2010. Two laboratories participated in this study. Each of the two labs reported seven replicate test results for both the number of colony forming units per gram, and the Log proteolytic bacteria, of a single uncured hide material. Every �test result� reported represents an individual determination. Except for the use of only two laboratories, and a single material, Practice E 691 was followed for the design and analysis of the data; the details are given in ASTM Research Report No. D31-1017.
