适用范围： Note 1-All rosin sold in interstate commerce must be described by reference to the U. S. Standards for rosin, and is therefore subject to grading prior to such sale. The grading procedure described in these methods is used for checking grades or regrading after the rosin has moved from the primary markets to distributing or consuming points.
