Specifying Stainless Steel Surfaces for the Brewery, Dairy and Pharmaceutical Sectors

The paper gives an overview of the standards, guidelines (e.g. ASME BPE-2007, 3-A SSI, EHEDG, EN, ISO) and sector-typical requirements that are used to specify the stainless steel surfaces for process equipment in the brewery, dairy and pharmaceutical sectors. Moreover, by means of a case history the paper describes some often occurring problems and disputes related to the subsequent control of the actual delivered surfaces.
