NEW A PRODUCT LIFE CYCLE IMAGE WITH AN EULER DIAGRMA FOR THE DIFFERENT STANDARDS

Different agencies - approval is testing of new product
and verification to standard - manufacturing overwatch / supervision

\section{Legislation and Safety Standards}

European Directives - generalised goals for society -

\begin{itemize}
\item Environmental protection
\item Human Rights - safety in the workplace
\end{itemize}

Directives become safety goals, leading to Generic standards, for some equipemnt, specific standards are written

\section{ Safety Goals and safety Requirements}
Safety goals can be seen as general principles of safety.
Safety requirements, are speciific to the operatng conditions and environment
that the equipement is used in.
Safety goals can be considered a set of aspirations
to be applied to any system.

For every Safety requirement $S_{req}$ we should have a related safety goal
$S_{goal}$ for the requirments to be meaningful.

FIND LIST

\begin{itemize}
\item * To protect life and limb
\item * To protect the environment
\end{itemize}

We can express this as 
$$ \forall S_{req} \longrightarrow S_{goal}. $$
