Section 108.15. Fineness of agricultural liming material

(a) Label requirement. The label shall set forth the classification of the fineness of the agricultural liming material that is the subject of the label. The minimum percentages by weight of that agricultural liming material which will pass through United States Standard 20, 60 and 100 mesh sieves shall also appear on the label.

(b) Classification criteria. The classifications of the fineness of agricultural liming materials, as set forth in this subsection, are the minimum percentages by weight which shall be able to pass through various sizes of United States Standard sieves to earn a particular classification:

Classification	Sieve Size Minimums
Fine-sized	95% through a 20 mesh sieve 60% through a 60 mesh sieve 50% through a 100 mesh sieve
Medium-sized	90% through a 20 mesh sieve 50% through a 60 mesh sieve 30% through a 100 mesh sieve
Coarse-sized	Agricultural liming materials that fail to meet the minimums for fine-sized or medium-sized classification, as set forth in this subsection.

The provisions of this § 108.15 adopted March 4, 1994, effective March 5, 1994, 24 Pa.B. 1179.
