Introduction

In most applications, safety systems have been operating for many years using systems of electronic components. Currently, to calculate Machine-based systems and programmable electronic systems (PES) have been used in all areas for non-safety performance operations and more and more the more safety features operate. If computer system technology is effectively and safely developed for those decision-makers in making decisions it is crucial that there is sufficient guidance on the security aspects.

This standard is for electrical or electronic or programmable electronic components (E/E/PES) system in the operation of earth-moving machinery safety performance Made in.

In most cases, safety is accomplished by a large number of protective systems that rely on many technologies (eg mechanical, hydraulic, pneumatic, electric Electronic, programmable electronic). Therefore, any security strategy should consider more than just everything in a single system, such as sensors, Control equipment and drives, but also all safety-related systems. Therefore, when the standard and safety-related E/E /PES, it can also provide guidance on security systems that rely on other technologies.

This standard.

--- Has a rapidly evolving technology, and sufficient comprehensive regulations to meet the requirements of the technology required;

--- Provide a method for the development of the required safety performance specifications to define the required safety performance for E/E/PES;

- To demonstrate a methodology that clearly sets out the overall level of safety and uses a risk-based approach to implementing E/E /PES safety performance.
