National foreword This document (EN 12007-5:2014) has been prepared by Technical Committee CEN/TC 234 “Gas infra-structure” (Secretariat: DIN, Germany), The responsible German body involved in its preparation was the Normenausschuss Gastechnik (Gas Technology
6、Standards Committee), Working Committee NA 032-02-02 AA Gasverteilung. This European Standard supplements the general functional requirements of EN 12007-1 by describing specific functional requirements for the design and construction of service lines for a maximum operating pressure (MOP) up to and
7、 including 16 bar. Pressure testing and commissioning and decommissioning procedures are dealt with in DIN EN 12327. Technical Rules within the meaning of this standard are the following DVGW-Arbeitsbltter (DVGW Technical Rules): G 459-1, G 462, G 472 and G 469. The above technical rules give more d
8、etailed information supplementing the requirements of DIN EN 12007-5. In Germany, the main line ends at the main shut-off device, which is also the point at which ownership is transferred from the public grid operator to the customer. It is intended to include this standard in the body of technical
9、rules and standards for gas issued by the DVGW Deutscher Verein des Gas- und Wasserfaches e.V. (German Technical and Scientific Association for Gas and Water).

This European Standard is part of the series EN 12007 “Gas infrastructure Pipelines for maximum operating pressure up to and including 16 bar“ which comprises the
25、 following parts: Part 1 General functional requirements; Part 2 Specific functional requirements for polyethylene (MOP up to and including 10 bar); Part 3 Specific functional requirements for steel; Part 4 Specific functional requirements for renovation; Part 5 Specific functional recommendations o

DIN EN 12007-5:2014-07EN 12007-5:2014 (E) 5 Introduction This Euro
28、pean Standard describes the general functional requirements for gas supply through service line pipe systems and covers the pressure range up to and including 16 bar maximum operating pressure (MOP). It gives normative and informative references for safe and secure gas infrastructures. It applies to
29、 their design, construction, operation and the related aspects of safety, environment and public health, all in order to provide a safe and secure supply of gas. This European Standard is intended to be used in addition to the EN 12007 series of European Standards. The requirements of this European
30、Standard are based on safe gas engineering practice under conditions normally encountered in the gas industry. Requirements for all unusual conditions cannot be specifically provided for, nor are all engineering and construction details prescribed. Existing industrial safety regulations applying to
31、work areas, safety devices and safe work practices are not intended to be supplanted by this European Standard. Persons responsible for the design, construction and operation of gas infrastructures should have regard to the guidance given in this European Standard, the EN 12007 series of European St
32、andards and to other relevant standards. It is the responsibility of these persons to apply these functional requirements, supplemented with other proven good practice to the particular circumstances of each gas infrastructure. The recommendations in this European Standard are intended to be applied
33、 by competent persons who have suitable knowledge and experience. Notes in the text are informative. The designer, constructor or operator of service line and pipeline systems is cautioned that this European Standard is not a design handbook or code of practice. Additional national or company standa
34、rds describing the details are needed. These detailed standards should be in line with the basic principles of this European Standard. All pressures are gauge pressure unless stated otherwise. In preparing this European Standard it was recognised that the suite of relevant European Standards is inco
35、mplete. Reference may be made where appropriate to international, national or other standards until relevant European Standards are available. DIN EN 12007-5:2014-07EN 12007-5:2014 (E) 6 1 Scope This European Standard describes the specific functional requirements for service lines in addition to th
36、e general functional requirements of EN 12007-1 for: a) a maximum operating pressure (MOP) up to and including 16 bar; b) an operating temperature between -20 C and +40 C. It applies to their design, construction, commissioning, decommissioning, operation, maintenance, extension and other associated
37、 works. The service line is the physical asset comprising of pipework from the gas main branch saddle or top tee to the outlet of the distribution system operators nominated point(s) of delivery (for example: isolation valve, regulator, meter connection or combination of regulator and isolation valv
38、e). The ownership and operation responsibility can vary between member states. The extent of the service line can differ in each member state. To illustrate this, the various points of deliveries are indicated in Figure 1. Consult Figure 1 (A/B/C/D/E) and member state regulations and standards. NOTE
39、 The valve at point A is not necessarily utilised by each member state. National preference for points of deliveries should be stated in the national foreword.

DIN EN 12007-5:2014-07EN 12007-5:2014 (E) 7 pressure regulating installations are
42、given in EN 12279 or EN 12186. pressure testing, commissioning and decommissioning are given in EN 12327. This European Standard represents the recommendations at the time of its preparation. It does not apply retrospectively to installations before the publication date unless specifically stated. T
43、his European Standard specifies common basic principles for gas infrastructure. Users of this European Standard should be aware that more detailed national standards and/or code of practice may exist in the CEN member countries. This European Standard is intended to be applied in association with th
44、ese national standards and/or codes of practice setting out the above-mentioned basic principles. In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this European Standard, the national legislation/regulation takes preceden
45、ce as illustrated in CEN/TR 13737 (all parts). CEN/TR 13737 (all parts) gives: clarification of all legislations/regulations applicable in a member state; if appropriate, more restrictive national requirements; a national contact point for the latest information. 2 Normative references The following
