(Main)Gas safety shut-off devices for inlet pressure up to 10 MPa (100 bar)
Gas safety shut-off devices for inlet pressure up to 10 MPa (100 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.
Some clauses of this standard should be re-considered at the time when characteristics for nonconventional
gases will be available.
Gas safety shut-off devices according to this European standard do not have their own source of ignition
and therefore are not within the scope of European Directive 2014/34/EU. Any additional component
(e.g. proximity switch, travel transducer etc.) should be independently considered in the framework of
assemblies per ATEX Guideline to the application of Directive 2014/34/EU of the European Parliament
and of the Council of 26nd February 2014, edition December 2017, §§42 and 43.
The document includes also environmental considerations.
