Active Standard: C670 - 13
The work item involves a major revision to Practice C670. These revisions will include a new terminology section that conforms to the Form and Style for ASTM Standards. The section on general concepts will be revised to clarify the meaning of single-operator and multi-laboratory precision. The link between Practice C670 and Practice C802 will be clarified, and the link with Practice E177 will be discussed. The requirements for a temporary precision statement in a new test method will be explained. Examples of precision statements will be moved to a new Appendix. The existing Appendix will be removed because it does not belong in Practice C670.
