European foreword
This document (EN 50194-2:2019) has been prepared by CLC/TC 216 “Gas detectors”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2020–03–18
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2022–03–18
conflicting with this document have to be
withdrawn
This document supersedes EN 50194-2:2006.
This Part 2 is intended to be used in conjunction with EN 50194-1:2009.
This European Standard supplements or modifies the corresponding clauses of EN 50194; where it states
“addition”, “modification” or “replacement” the relevant text of EN 50194 is to be adapted accordingly.
Subclauses, tables and notes that are numbered starting from 101 are additional to those in Part 1.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
CENELEC shall not be held responsible for identifying any or all such patent rights.
1 Scope
This Clause of EN 50194-1 is replaced by:
This document specifies test methods and performance requirements for electrical apparatus for the detection of
combustible gases designed for continuous operation in a fixed installation in recreational vehicles and similar
premises.
NOTE 1 For caravan holiday homes EN 50194-1 applies.
This document specifies apparatus designed to operate in the event of an escape of liquefied petroleum gas (LPG)
and/or petrol (gasoline) vapour and to provide a visual and audible alarm and an executive action in the form of an
output signal that can actuate directly or indirectly a shut-off device and/or other ancillary device (Type A of
EN 50194-1).
The document excludes apparatus for the detection of toxic gases such as carbon monoxide (see EN 50291).
Apparatus complying with this document is not considered suitable for industrial or commercial installations for
which EN 60079-29-1 apply.
NOTE 2 Apparatus tested in accordance with EN 60079-29-1 will not necessarily comply with this standard.
