AS 3993:2003 pdf download.Equipment for the pasteurization of milkand other liquid dairy products— Continuous-flow systems.

4 MATERIALS

Equipment and all attachments that are in. or may come into, contact with milk and other liquid dairy product shall be manufactured from stainless steel or materials which are resistant to products being processed. non-toxic, resistant to cleaning agents and

disinfection agents in normal conditions of dosage and temperature, and shall not impart a taint to milk and other liquid dairy

product.

The grade of stainless steel shall be of a quality at least equivalent to the grade specified in ASTM A480/A480M. especially in

regard to suitability for welding and resistance to corrosion.

All product contact surfaces shall be smooth and free of crevices.

Stainless steel product contact surfaces should have a surface roughness (Rh) less than or equal to 1.0 pm. where R, is as defined in ISO 4288. A roughness of greater than 1.0 pm may be acceptable if test results have shown that required cleanahility is

achievable because of design features.
