What is BS EN 50271 - Requirements and tests for apparatus using software and/or digital technologies about?
BS EN 50271 is applicable to electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen.
BS EN 50271 specifies minimum requirements and tests for electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen using software and/or digital technologies.
Note:
BS EN 50271 does not apply to external sampling systems which are not accessories, or to apparatus of laboratory or scientific type, or to apparatus used only for process control purposes.
Who is BS EN 50271 - Requirements and tests for apparatus using software and/or digital technologies for?
BS EN 50271 on requirements and tests for apparatus using software and/or digital technologies is useful for:
- Domestic premises
- Commercial premises (industrial applications and their software-controlled safety-related accessories)
- Manufacturers of electrical products
- Gasol industries
Why should you use BS EN 50271 - Requirements and tests for apparatus using software and/or digital technologies?
BS EN 50271 specifies minimum requirements for functional safety of gas detection apparatus using software and/or digital technologies and defines criteria that will help you improve reliability and avoidance of faults. Also, functional safety is that part of the overall safety that is related to the measures within the gas detection apparatus that will help you to avoid or to handle failures in such a manner that the safety function will be ensured.
Overall, the Gas detection apparatus will fail to function if dangerous failures occur. The aim of BS EN 50271 is to reduce the risk of dangerous equipment failures to levels appropriate to typical applications of such apparatus. You can use BS EN 50271 recommendation for apparatus used for safety applications with SIL-requirement 1 instead of EN 50402.
What’s changed since the last update?
BS EN 50271:2018 supersedes BS EN 50271:2010, which is withdrawn.
