Sec. 6.11. Procedures for testing of universal samples

(a) A universal sample shall be tested by a method, and in compliance with the provisions, set forth in Standard Methods. The result of each test upon a universal sample shall be expressed as a percentage, to the nearest 0.05 percent when the Babcock or Gerber method is used and to.01 percent when electronic or ether extraction method is used, with the percentage representing the amount of the milk component tested for in the universal sample.

(b) No universal sample shall be tested more than 72 hours after having been taken from a dairy farm unless a preservative has been properly added to such universal sample prior to the expiration of such 72-hour period, in accordance with the provisions set forth in Standard Methods.

(c) No universal sample shall be tested if it is in a condition where the amount of a component or components therein being tested for cannot be accurately determined. With regard to tests done by the Babcock or Gerber method, a universal sample which has been tested to determine the amount of milk fat therein shall be re-tested if the fat column contains charred, foreign matter, curd particles; is milky, foggy, cloudy or indistinct; or if the meniscus is inverted. No result of testing shall be recorded or reported if the fat column is in such a condition.
