EHEDG - European Hygienic Equipment Design Group

The EHEDG is an independent consortium formed in 1989 to develop guidelines and test methods for the safe and hygienic processing of food. The group includes representatives from research institutes, the food industry, equipment manufacturers and government organisations in Europe.

They have developed a standard test procedure for assessing cleanability based on comparing the cleanability of a test item with that of a straight length of pipe with a surface roughness of 0.5µm Ra.

The 'CH' range has been independently assessed to this in-place cleanability protocol.
