Written application for membership is to be submitted to the oSa secretary's office and with it the willingness to adhere to the oSa's safety code.

Basis for the in-house tests stipulated by the oSa is the Technical Annex (as of March 2008).

The oSa requests from its members the creation of safe and healthy working conditions and a responsible environmental behaviour (see Ethical Annex, as of August 2006).
