Standard Practice for Writing Quality Control Specifications for Standard Test Methods for Water Analysis
 N D5847

Annotation

This practice provides specific, mandatory requirements for incorporating quality control (QC) procedures into all test methods under the jurisdiction of Committee D-19.

ASTM has adopted the following:

Policy on implementation of requirements for a quality control section in standard test methods generated by Committee D-19 on Water.

GENERAL—By July 29, 1998, or at the next reapproval or revision, whichever is later, every D-19 Standard Test Method shall contain a QC section that is in full compliance with the requirements of this practice.

NEW COLLABORATIVE TESTING—As of July 29, 1998, each collaborative study design shall include a QC section as part of the method to be tested. Prior to approval of the study design, the Results Advisor shall ascertain the appropriateness of the QC section in meeting the requirements of this Practice and Practice D2777, and shall advise the designer of the study of any changes needed to fulfill the requirements of these practices. Before a collaborative study may be conducted, approval of the study design by the Results Advisor must be obtained.

OLDER VALIDATED METHODS—Standard test methods that were validated using D-2777-77, D-2777-86, or D-2777-94, when ballotted for reapproval or revision, shall contain a QC section based upon the best information from the historical record. Where appropriate, information derived from the record of the collaborative study shall be utilized for this purpose. The introduction of the QC section into these standard test methods shall not be construed as a requirement for a new collaborative study, though the Subcommittee may opt for such a study. Any information available regarding QC or precision/ bias testing shall be included in the appropriate sections of the published method.
