|Abstract:||Procedures for testing research materials for the determination of the extent of within-specimen heterogeneity and between-specimen heterogeneity are described. These procedures, which have been developed and used at NIST in the certification of several NIST Standard Reference Materials (SRM's), have been recently simplified for general use. Suggestions for experimental testing of specimens are described and a detailed description of the statistical evaluation process is included. An example of a data spreadsheet and instructions for its preparation are included.|
