Chapter 520. Rules and Regulations Governing Testing of Milk for Milkfat, Protein, and Lactose Content by Automated Instrument Methods
2VAC5-520-10. Definitions.
The following words and terms, when used in this chapter, shall have the following meaning, unless the context clearly indicates otherwise:
"AOAC" means the Association of Official Analytical Chemists.
"Automated instrument methods" means any contrivance, machine, or device manufactured for the purpose of automating the determination of the fat, protein, or lactose content of milk or milk products.
"Calibration" means the adjustment of the automated instrument so that it will reproduce the test results obtained by the reference method.
"Infrared milk analyzer method" means the automated instrument method that determines the fat, protein, and lactose content of milk by determining the amount of infrared rays of different lengths absorbed by a portion of a sample of milk.
"Light scattering methods" means the automated instrument that determines the fat content of milk by measuring the amount of light diffused by a portion of a sample of milk placed between a light source and a photometer.
"Permit to calibrate and operate" means a permit authorizing a person to test milk by the reference methods, calibrate, adjust, operate, perform maintenance, and maintain official records when automated instruments are in use.
"Permit to operate" means a permit authorizing a person to prepare samples, present the samples to the automated instrument, record test results, and perform routine maintenance.
"Permit to test milk by the reference methods" means a permit authorizing a person to test milk by the Babcock method or other methods approved by the State Regulatory Authority and the Association of Official Analytical Chemists for the purpose of calibrating automated testing instruments.
"Person" means any individual, plant operator, partnership, corporation, company, firm, trustee, or associate.
"Reference methods" means the method approved by the State Regulatory Authority to be used to determine the fat, protein, or lactose content of samples of milk to be used as a basis of calibrating the automated instruments.
"State Regulatory Authority" means the Virginia Department of Agriculture and Consumer Services.

2VAC5-520-30. Permits.
A. No person shall operate automated testing equipment to determine the fat, protein, and lactose content of milk for the purpose of official inspection, check testing, or as a basis for payment in buying or selling unless facility and equipment requirements have been satisfied and a permit obtained from the State Regulatory Authority.
B. When an automated testing instrument is used to determine the fat, protein, and lactose content of milk for the purpose of official inspection, check testing, or as a basis for payment in buying or selling, it shall be unlawful for any person who does not possess a permit from the State Regulatory Authority to:
1. Calibrate and operate an automated testing instrument.
2. Operate only an automated testing instrument.
3. Test milk by reference methods.
C. The State Regulatory Authority shall suspend such permit whenever:
1. The permit holder has violated any of the requirements of this chapter; or
2. The permit holder has interfered with the State Regulatory Authority in the performance of its duties.
D. The State Regulatory Authority shall in all cases except where there is a gross violations or in any case of a willful refusal to permit authorized inspection, serve upon the holder a written notice of intent to suspend permit which notice shall specify with particularity the violations in question, and afford the holder such reasonable opportunity to correct such violations.
