With the introduction of the Certification Scheme for Detection of Explosive Remnants of War (CS-OOO) as of 01-01-2021, there are many changes regarding the regulations for explosives testing. This also applies to the preliminary examination. The Ministry of Social Affairs and Employment has decided not to include the requirements for the preliminary investigation from the former WSCS-OCE in the new CS-OOO. Consequently, the Voluntary Certification Scheme for the Preliminary Investigation and Risk Analysis of Explosive Remnants of War (CS-VROO) has been drawn up by the VOMES Foundation. With this, pre-investigations and risk analyses are subject to requirements and externally audited by TUV-Nederland to guarantee quality. A thorough preliminary investigation and risk analysis ultimately translates into an accurate insight into the OO that may be encountered. This insight leads to a cost reduction during the execution by preventing stagnation of the unexpected discovery of OO or eliminating the risk with a reduced detection effort. Therefore, ECG is certified in accordance with the CS-VROO. You can read more information about the CS-VROO here.
