(Practice)Standard Practice for Annual Review of Test Methods and Specifications for Plastics
Standard Practice for Annual Review of Test Methods and Specifications for Plastics
SIGNIFICANCE AND USE
4.1 It is the intention of this practice, in addition to the Form and Style for ASTM Standards, to assist persons revising test methods and specifications in Committee D20 to ensure that all required elements are included and that the revised document is presented in the most user-friendly manner possible.
4.2 This practice is intended for use by Committee D20 when test methods and specifications under its jurisdiction are revised because of technical changes or upon five-year review.
4.3 The flowcharts in Annex A1 show the review process and the precision and bias process in outline form.
4.4 Specific instructions to be followed when revising Committee D20 documents are given in this practice.
4.5 The model precision and bias (P and B) statements included in Annex A3 were developed to standardize the presentation of data.
SCOPE
1.1 This practice is intended to assist the subcommittees and sections of Committee D20 on Plastics with the process of standards evaluation during the five-year review mandated by ASTM or when changes to test methods and specifications are required. It is intended to complement the Form and Style for ASTM Standards (“Blue Book”) not replace it.
Note 1: There is no known ISO equivalent to this standard.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
