New Practice for Reporting Degradation Results of Weathering Tests on Exposed Specimens
1. Scope
1. Scope
1.1 This standard describes the use of a template for reporting the results of weathering tests or coatings defects on paint. This report may also be used when reporting degradation on large structures.
1.2 This report form is primarily intended for the reporting of defects that are produced on painted metal and wood substrates as a result of outdoor weathering exposure. The report may also be used for the reporting the weathering effects on any other type of material, such as plastic or composites.
1.3 This report form may also be used to report degradation effects after laboratory accelerated exposure.
1.4 This standard describes the ten to zero scale for evaluations also referred to in the D01 Handbook. This standard 10 point scale has been widely used for many years to report quantitative and qualitative effects that are determined subjectively.
1.5 Instrumentally obtained numbers may also be reported on this form. For example instrumental gloss measurements can be entered in any of the columns as desired.
1.6 This standard may be applied both by individuals conducting their own evaluations, and by third party testing laboratories.
1.7 The report form shown in Figure 1 is only an example of how these criteria may be collated onto a single report page. Other formats, which include these factors, would also be acceptable. Other items may also be reported over and above these requirements.
1.8 Test laboratories may generate reports using their own software programs and including their own company logos, provided that they comply with the minimum requirements of this standard.

Rationale
To satisfy the basic requirements for reporting the effects of weathering degradation after exposure.
