The  European Committee for Standardization (CEN)  Workshop Agreement 16393 (CWA 16393): Laboratory Biorisk Management Standard- Guidelines for Implementation of CWA 15793: Laboratory Biorisk Management Standard is a companion guide that focuses on how to carry out the plan-do-check-act cycle outlined in CWA 15793. CWA 16393 was published in 2011, when CWA 15793 was being updated, and the document is structured as implementation guidance notes surrounding the CWA 155793 text. These Guidelines do not add any new requirements, and are meant to give context to existing requirements. The document is available in English, French and German.
