Scope

This proposed revision of the Standard 41.9 updates the 2006 edition by citing the most recent reference sources, by making procedural revisions to the lubricant circulation rate measurement in Section 11, and by other revisions to bring this standard into compliance with ASHRAE's mandatory language requirement. Various minor changes make it more usable and easier to read.
