这些3-A公认实践应适用于牛奶和奶制品完整巴氏杀菌系统中使用的高温短时（HTST）和高温短时（HHST）巴氏杀菌设备、附件和控制装置。除巴氏杀菌外，此类系统还可包括风味控制、真空处理、均质、澄清、分离或其他过程，如果包括这些过程，则应安装这些系统，以使其不会影响所需的时间、温度、流量和压力关系。

These 3-A Accepted Practices shall pertain to high-temperature short-time (HTST) and higher-heat shorter-time (HHST) pasteurization equipment, appurtenances, and controls used in a complete pasteurization system for milk and milk products. In addition to pasteurization, such systems may include flavor control, vacuum treatment, homogenization, clarification, separation, or other processeswhich if included, are to be installed so that they do not influence required time, temperature, flow and pressure relationships.
