5.1.5.2 Certification Matrix The purpose of the Certification Matrix is to provide clarity as to what the certification or acceptance criteria are for each system and sub-system. This document will be crucial to the logistics organisation of the project to ensure that systems and equipment are designed and manufactured to the correct standards and have the appropriate certification. The level of detail for this document will be dependent on the project complexity and the requirements of the navy. 5.1.6 Selection of engineering system categories Within the Naval Ship Rules, each engineering system is categorised in order to apply a hierarchy of assessment. This is because it is accepted that within the Naval Ship Rules the scope of systems and equipment falling under the scrutiny of class is much greater. With this increase in scope it is clear that it is undesirable for all systems and equipment’s to be subjected to the most rigorous levels of class oversight. The concept of system categories addresses this.
