Exclusion of liability Care has been taken in production of the software, which corresponds to the state of the art. Used Software ZeosLib, Version 7. It is then installed and run locally, providing very useful functionality in its free 'demo mode'. The system designer [typically a machine designer or integrator] will use this data to perform some relatively straightforward calculations to determine the overall Performance Level [PL] of the system.

In order to determine what PL is required [PLr] the standard provides risk graph into which the application factors of severity of injury, frequency of exposure and possibility of avoidance are input. The output is the PLr. Users of the old EN will be familiar with this approach but take note that the S1 line now subdivides whereas the old risk graph did not. Note that this means a possible reconsideration of the integrity of safety measures required at lower risk levels.

There is one very important part yet to be covered however. We now know from the standard how good the system needs to be and also how to determine how good it is but we don't know what it needs to do. We need to decide what the safety function is. Clearly the safety function must be appropriate to the task so how do we provide this? How does the standard help us? It is important to realise that the functionality required can only be determined by considering the characteristics prevailing at the actual application.

This can be regarded the safety concept design stage. It cannot be completely covered by the standard because the standard does not know about all the characteristics of a specific application. This also often applies to the machine builder who produces the machine but does not necessarily know the exact conditions under which it will be used. The standard does provide some help by listing out many of the commonly used safety functions and giving some normally associated requirements.

Also there is a large range of machine specific standards that will provide solutions for specific machines. So we can now see that the safety concept design stage is dependent on the type of machine and also on the characteristics of the application and environment in which it is used.

Background of Revision Overview of Revision. ISO Performance level PL was introduced in ISO , which is quantitatively expressed as the reliability of safety-related parts of a control system, including diagnostic coverage or failure rate. Reference: Requirements before Revisions ISO specified the determination method of category and its requirements. They were placed on your computer when you launched this website.

EN ISO serves as a basis for evaluation of the safety of complex machine controls. The normative requirements governing safety-related machine controls are set out in close detail in the applicable safety standard, EN ISO formerly EN As a result, it was possible for the comprehensive experience gained during research and product testing to be channelled back effectively into the standards development process.

The proven categories from EN have been retained, but safety-related properties are also assessed quantitatively through statistical calculation methods.
