CIMAC Recommendations

The following CIMAC Recommendations have been prepared by the CIMAC Working Groups. CIMAC Recommendations are the most formal CIMAC publications prepared by the CIMAC Working Groups, aimed typically at the description of a technical matter, giving background information and providing recommendations as to how to deal with the topic.

The recommendations can now be downloaded as pdf-files by clicking on the description of each entry below or via the 'Download' option on the left hand side or from the Technical Paper Database. The downloads are free of charge for all.
