ASTM C670-96
Historical Standard: ASTM C670-96 Standard Practice for Preparing Precision and Bias Statements for Test Methods for Construction Materials
SUPERSEDED (see Active link, below)
ASTM C670
1. Scope
1.1 This practice supplements Practice E177, in order to provide guidance in preparing precision and bias statements for ASTM test methods pertaining to certain construction materials (Note 1). Recommended forms for precision and bias statements are included. A discussion of the purpose and significance of these statements for the users of those test methods is also provided.
Note 1-Although under the jurisdiction of Committee C-9, this practice was developed jointly by Committees C-1, D-4, and C-9, and has been endorsed by all three committees. It has subsequently been adopted for use by Committee D-18.
