Member of ASTM, Chief, Washington, D.C.,
Materials specification limits should minimize materials and testing costs while providing adequate protection for both producer and consumer. The publication of precision statements in ASTM test methods makes possible a rational method for establishing the number of determinations to be averaged for a reported test result for a given test method and is useful in establishing specification limits for mutually dependent properties and for comparisons between treated and untreated materials. Detailed procedures are given for establishing specification limits for the heat of hydration of portland cement and the contribution to durability of concrete admixtures.
