This is the third revision, with the first edition published in 2002, and a second edition in 2006. The standard is effective on June 14, 2022, and applies to the sanitary aspects of centrifugal separators or clarifiers used to separate fractions of milk or milk products or other liquid food products or to centrifugally remove dense phase material from products.  Product enters at the product inlet(s) and exits at the product outlet(s) and the non-product discharge(s), when included.
