The accepted and best way to acquire data as a basis for writing a precision statement for a test method is to conduct an interlaboratory study designed for that purpose. However, it is sometimes possible to develop a usable precision statement with data from other sources, such as historical data or data from a recognized reference sample program. This paper gives examples of such statements developed for two ASTM methods and describes how they were developed.
