A major objective of this standard is to facilitate the development of product iec 61508-1 application sector international standards by the technical committees responsible for the product or application sector. It kec the status of a basic safety publication according to IEC Guide iec 61508-1 It is being widely adopted by the major car manufacturers.
This second edition cancels and replaces the first edition published iec 61508-1 It has been subject to a thorough review and incorporates many comments received at the various revision stages. It is iec 61508-1 to cover the development of software for railway control and protection including communications, signaling and processing systems.
The meaning of the SIL varies depending on whether the functional component will be exposed to high or low demand:.

It covers the safety systems of electrical equipment and their components that could have an impact on the iec 61508-1 of people and the environment if they fail. 16508-1 is a technical standard which sets out iec 61508-1 in the engineering of systems that ensure the safety of an industrial process through the use of instrumentation.
This article relies largely or entirely on a single source. Calculation iec 61508-1 safe failure fraction SFF determines how fail-safe iec 61508-1 system is. The requirement informs how to set up the development process using appropriate quality control, management processes, validation and verification techniques, failure analysis etc.

It indicates the general requirements for systems that contain conventional hardwired equipment, computer-based equipment or a combination of both types of equipment. Iec 61508-1 introduced anywhere from the initial concept, risk analysis, specification, design, installation, maintenance and through to disposal could undermine even the most reliable protection.
IEC is intended to be a basic functional safety standard applicable to all kinds of industry. Please help improve this article by introducing citations to additional sources.
Before the launch of ISOthe development of software for safety related iec 61508-1 systems was predominantly covered by the Iec 61508-1 Industry Software Reliability Association guidelines.
This will allow all the relevant factors, associated with the product or application, to be fully taken into account and thereby meet the specific needs of iec 61508-1 of the product and the application iec 61508-1.
The standard covers the complete safety life cycleand may need interpretation to develop sector specific standards.
