-   SSDs designed to be incorporated into pressure-regulating devices used in service lines  with volumetric flow rate ≤ 200 m3/h at normal conditions and inlet pressure ≤ 5 bar.
Continued integrity of safety shut-off devices is ensured by periodic functional checks. For periodic functional checks it is common to refer to national regulations/standards where existing or users/manufacturers practices.
This document considers the reaction of the SSDs functional class A to the specified reasonable expected failures in terms of "fail close" behaviour, but it should be consider that there are other types of failures whose consequences cannot bring to the same reactions (these risks are covered via redundancy as per EN 12186) and that residual hazards should be reduced by a suitable surveillance in use / maintenance.
In this document, both safety shut-off devices that can be classified as "safety accessories" by themselves according the Pressure Equipment Directive (2014/68/EU) as well as safety shut-off devices that can be used to provide the necessary pressure protection through redundancy (e.g. shutoff device integrated in a pressure regulator, shut-off device with a second shut-off device) are considered. Addition of environmental considerations;
The provisions in this document are in line with the state of art at the moment of writing.
This document does not intend to limit the improvement of actual provisions (materials, requirements, test methods, acceptance criteria, etc.) or the developing of new provisions for SSDs where they are suitable to ensure an equivalent level of reliability.
