1.1 These test methods cover procedures for sampling and determining the grade of rosin delivered in commercial bags, barrels, drums or in molten form. Although developed for rosin, these methods can also be used for the grading of modified rosins and rosin based resins.
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 test methods is used for checking grades or regrading after the rosin has moved from the primary markets to distributing or consuming points.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
