Print this article | Send to Colleague

A revision has been proposed for T 257 om-12 "Sampling and preparing wood for analysis." The current method specifies a 40 mesh (0.40 mm) screen, but contains no definition of what type or screen is specified. A "40-mesh" screen may mean different sizes in different systems.

The proposed revision is to describe the screen more clearly by referring to an ASTM standard.
