Research Report RR:D03-1009
An interlaboratory study was conducted by six laboratories reporting Hydrogen sulfide, Carbonyl sulfide, and methyl mercaptan concentrations on three different materials to establish precision statements for D5504. Every "test result" reported represents an individual determination. Each participating laboratory reported five replicate test results for every material.
