It is the intention of this guide to provide information to 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.

This guide is intended for use by Committee D20 when test methods and specifications under its jurisdiction are revised due to technical changes or upon five-year review.

The flowchart in Annex A1 shows the review process in outline form.

Specific instructions to be followed when revising Committee D20 documents are given in this guide.

The model precision and bias (P and B) statements included in Appendix X1-Appendix X3 were developed to standardize the presentation of data.
