SR EN 15233:2008

This European Standard provides guidance on the procedure and information required to allow functional safety assessment to be carried out for the design of protective systems. The purpose of this European Standard is to assist technical standardization committees responsible for specific families of protective systems in preparing safety standards. Such standards shall be as homogenous as possible and shall have the basic structure of functional safety assessment as it is stated in this standard. If there are no specific standards for a particular protective system, the manufacturer shall use this standard for functional safety assessment of this protective system. In this procedure the following information is to be taken into account to ensure a sufficient level of functional safety: a) intended use, b) possible operating faults, c) reliability of protective systems, d) misuse which can reasonably be anticipated. A sufficient level of functional safety is characterized by the following objectives: 1) System can stop an explosion at a very early stage or reduce the impact of
