(a) Gypsum (CaSO4) shall not be considered as an agricultural liming material.

(b) "Fineness" of a product shall be determined by passing a sample through a number eight (8) and number sixty (60) U.S. Standard Sieve, and calculating the percentage of weight of the material which passes through each sieve. The minimum "fineness" for any agricultural liming material distributed for use in Oklahoma shall be that 98% must pass through a four (4) mesh, 90% must pass through an eight (8) mesh and 30% through a sixty (60) mesh sieve.

(c) The "fineness factor" of a product shall be calculated as one-half (1/2) the percent passing through a number eight (8) sieve plus one- half (1/2) the percent passing through a number sixty (60) sieve equals "fineness factor."
