Article

Cleanability is also a term used in clean productions (e.g. to assess the cleanability of technical surfaces). We would like to delete the redirection and write an own article.

We would propose the following article (only content, no references so far included):

In order to ensure optimum cleanability of the surfaces of machines and equipment, they must fulfill certain requirements. Where surfaces come into contact with media, no deposits may be formed which could impair product quality. Therefore, the surface roughness of such areas should be below 0.8 µm (see EHEDG doc. 8). If the degree of roughness is exceeded, resistances may develop during disinfection processes. These occur when microorganisms only come into contact with disinfectants but are not killed by them. When ascertaining the cleanability of a surface with regard to particles, the analysis can be carried out in correlation with the surface cleanliness classes described in VDI 2083 Part 9.1. Surface roughness can be measured, for example, using profile methods (DIN EN ISO 11562) or AFM (atomic force microscope). However, no norm is cur-rently in existence which describes a standardized AFM procedure. — Preceding unsigned comment added by MXL S (talk • contribs) 07:47, 10 December 2010 (UTC)[reply]
