NRMCA Releases New Topic in Technology in Practice Series
Print this Article | Send to Colleague
A new topic in the NRMCA Technology in Practice (TIP) series is now available. TIP 20 – Understanding Variability of Test Methods—Precision Statements is an overview of the variability of test methods as indicated by the precision statement. This TIP describes the overall process by which the precision statement for a test method is developed. It also provides several ways this precision information can be used in practice, from understanding the reliability of test results from different tests; using it as a basis to eliminate test data; understanding components of variability besides that of testing and use of test method precision relative to specification criteria and tolerances.
TIPs are developed by the NRMCA Research Engineering and Standards (RES) Committee and are intended as an educational resource for ready mixed concrete industry personnel. Industry members are invited to suggest topics for future TIPs.
All TIPs can be previewed and purchased from NRMCA's website. For more information contact Colin Lobo at clobo@nrmca.org.
