Revision of E1918-21 Standard Test Method for Measuring Solar Reflectance of Horizontal and Low-Sloped Surfaces in the Field


The proposed edits provide an additional method that minimizes shadow error and eliminates background error by determining albedo from the sunlight reflected by a test specimen. The proposed method, using a smaller specimen size than the original method, is more practical for the user without decreasing the margin of error. Procedure A indicates the test method currently included in the standard while Procedure B is the proposed method being balloted.
The proposed test method was originally balloted to the D08.18 Subcommittee in November 2020 as a non-mandatory appendix.
