European foreword
This document (CEN/TR 16940:2016) has been prepared by CEN/SFG_I/SFG_U JWG “Safety of domestic
gas installations”, the secretariat of which is held by AFNOR/BNG.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
Introduction
As a result of the liberalization of the gas and services market in Europe and the need to reduce
potential barriers to trade, the development of mutually recognized standards covering design,
installation, inspection and maintenance of pipework and appliances downstream of the point of
delivery, including the development of a competence assessment scheme for gas operatives and
companies engaged in this sector is considered important.
The quality and safety of the gas installations are generally ensured through competent operatives,
installers and inspectors complying with technical regulations, inspection and maintenance regimes,
safety inspection of work .
To assist and facilitate the movement of operatives between states, a mutual recognition
framework/matrix that is agreed by all Member States can be envisaged. This should be designed and
developed to help Member States and those operatives wishing to relocate, to be able to benchmark
their respective knowledge, experience and qualifications against the requirements of the Host State. In
particular, the mutual recognition framework is described in the recommendations at the end of this
document.
1 Scope
This Technical Report gives recommendations to ensure the quality and safety of domestic gas
installations. This Technical Report covers pipe work, appliances installation, their combustion air
supply and flue products exhaust commissioning, inspection and maintenance activities carried out by
operatives.
This document addresses the following three main factors, which have an influence on gas safety in
general:
a) quality and safety of components of gas installations and gas appliances,
b) quality of the work when gas installations are constructed and commissioned,
c) inspection and maintenance of installations and gas appliances.
Potential ways in which individual competence of operatives and/or businesses can be ensured and
mutually recognized between Member States are considered.
The means of assuring responsible behaviour of consumers is not covered in this document.
It does not address metering or non-domestic (industrial and commercial) installations.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
CEN/TR 1749, European scheme for the classification of gas appliances according to the method of
evacuation of the combustion products (types)
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
(From CEN Guide 14)
(From Marcogaz National Competency Framework)
3.1
inspection
checking or testing of an installation, by duly competent operatives, against established parameters
(which may relate to emission limits), its performance and its conformance to safety requirements
(checking the actual condition against a target condition), followed by the supply of a written report
confirming either compliance with all test parameters or detailing identified deficiencies (where these
are deemed so significant as to warrant such action)
3.2
maintenance
performance of preventative examinations, checks, cleaning, adjustment and repairs necessary to
maintain target conditions, and the remedying of deficiencies identified during inspection by duly
competent operatives, re-establishing target conditions as necessary
4 Assuring the quality of installation and service work
Domestic gas installations offer safe, efficient and user-friendly comfort to end-users provided they are
designed and installed by competent operatives, together with adequate maintenance and regular
inspection.
The competencies needed are given in 7.2; how to assess them in dealt with is given in 8.1 and 8.2.
In order to ensure quality and safety of gas installations, the following elements shall be considered:
— technical requirements for pipe work;
— technical requirements for appliance installations, including combustion air supply, ventilation and
flue products exhaust;
— prescriptions for inspection and maintenance of installations and appliances;
— if applicable, prescriptions for third party safety inspection of new and existing installations;
NOTE Safety inspection will often be incorporated into a maintenance specification, but may be offered
as a separate service, which can be compulsory, in the interests of assuring adequate safety performance of
an appliance/installation at an economic cost.
— assuring competence of operatives.
There is considerable variation, across Member States, with regards to the manner in which these
elements are provided for. Each of these elements are considered, in order to provide a basis for a
European best practice for minimum safety requirements.
Technical standards may be complemented by more detailed national standards, which should be
applied in association with European Standards, but will not conflict with them. There may also be
additional requirements in national legislation / regulations, particularly those relating to the
construction of services within buildings, which shall take precedence.
5 General technical requirements for pipework
General technical requirements for pipework, so as to achieve a consistent basis for the safe and
efficient installation of gas pipework in domestic premises, are given in EN 1775.
EN 1775 covers principles of gas supply systems.
This functional standard specifies the common appropriate principles and the recognized practices
concerning:
— design;
It is emphasized that gas pipework shall be sized so that the pressure at the inlet of all gas
appliances is compatible with their safe and effective operation.
— installation and construction;
— testing;
— commissioning;
— operation and maintenance;
— working on operating pipe.
It shall be applied by competent persons who have suitable knowledge, experience and approval.
The standard is for pipework between the point of delivery of the gas and the inlet connection to the gas
appliances. It applies to new installation pipework and replacement of, or extensions to, existing
pipework. It does not cover buried pipework, gas metering systems, LPG storage vessels or single
appliance LPG installations without fixed pipework, achieved by a flexible appliance connector from an
adjacent LPG storage cylinder.
6 Technical requirements for appliance installations
6.1 General
This clause deals with the achievement of a consistent basis for the sustainable, safe and efficient
installation of gas appliances in domestic premises, whether in specific appliance rooms or other spaces
where gas appliances are installed, in relation to the requirements for:
a) design and installation;
b) correct appliance selection;
c) correct location;
d) combustion and ventilation air;
e) flue products exhaust;
f) correct commissioning;
g) correct maintenance.
It shall be applied by competent persons who have suitable knowledge, experience and approval.
The occupants and owners of domestic dwellings are responsible for the installation during its
operation. They shall be provided with written information about the functioning, maintenance and
safety of the appliances.
Single appliance LPG installations without fixed pipework, achieved by a flexible appliance connector
from an adjacent LPG storage cylinder are also considered in this document.
6.2 Competence of operatives
The general requirements for competence are dealt with in 8.1
