D4483-20 – Standard Test Method Technical Guide
ASTM D4483-20 serves as the definitive governing practice for evaluating the precision of test methods within the rubber and carbon black manufacturing industries. While it is built upon the foundational one-way analysis of variance (ANOVA) calculation algorithms of Practice E691, D4483-20 expands significantly into robust statistical procedures specifically designed to handle the historical precision challenges unique to these sectors.
