Standard Practice for Annual Review of Test Methods and Specifications for Plastics
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 figures in Annex A1 contain three flowcharts. Fig. A1.1 is a flowchart that shows the review process for standards that have been revised or reapproved recently. Fig. A1.2 is a flowchart for standards that have neither been revised nor reapproved within five years of a new review. Fig. A1.3 is a flowchart for 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.
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.
