NR 240.03 NR 240.03 Definitions. The following definitions are applicable to terms used in this chapter. Definitions of other terms and meanings of abbreviations are set forth in ch. NR 205.

NR 240.03(1) (1) “BOD input” means the 5 day biochemical oxygen demand of the materials entered into process. It can be calculated by multiplying the amounts of fats, proteins, and carbohydrates by factors of 0.890, 1.031, and 0.691, respectively. Organic acids, e.g. lactic acid, should be included as carbohydrates. The composition of input materials may be based on either,

NR 240.03(1)(a) (a) Direct analysis, or

NR 240.03(1)(b) (b) Generally accepted published values such as specifically those in s. NR 240.07.

NR 240.03(2) (2) “Milk equivalent” means the quantity of 3.7% fat content whole milk necessary to supply one pound of fluid raw material to a process.
