This document gives guidelines for the design, construction and operation of all onshore liquefied natural gas (LNG) installations for the liquefaction, storage, vaporization, transfer and handling of LNG and natural gas (NG). These requirements may be applied to bio methane and synthetic natural gas (SNG) accordingly.

This document is valid for plants with LNG storage at a capacity above 200 t.

The designated boundary limits are LNG inlet/outlet by the ship’s manifold including vapour return connection, the truck loading /unloading connection including vapour return, the rail loading/unloading connection including vapour return and the natural gas in and outlet boundary by piping systems.

Terminals or plant types have one or more boundary limits as described in this scope.

A short description of each of these installations is given in Annex G.

Feed gas for LNG liquefaction installations (plant) can be from gas field, associated gas from oil field, piped gas from transportation grid or from renewables.

Floating solutions (FPSO, FSRU, SRV), whether off-shore or nearby shore, are not covered by this European Standard even if some concepts, principles or recommendations could be applied. However, in case of berthed FSRU with LNG transfer across the jetty, the following recommendations apply for the jetty and topside facilities.

In case of FSU type solution, the on-shore part is covered by these standard recommendations.

This standard is not applicable for installations specifically referred or covered by other standards, e.g. LNG fuelling stations, LNG road or rail tankers and LNG bunkering vessels.

The plants with a storage inventory from 5 t up to 200 t are covered by EN 13645.

This International Standard defines the integration of KNX protocol implementations on top of Internet Protocol (IP) networks, called KNXnet/IP. It describes a standard protocol for KNX devices connected to an IP network, called KNXnet/IP devices. The IP network acts as a fast (compared to KNX Twisted Pair transmission speed) backbone in KNX installations.

Widespread deployment of data networks using the Internet Protocol (IP) presents an opportunity to expand building control communication beyond the local KNX control bus, providing:

remote configuration;

remote operation (including control and annunciation);

fast interface from LAN to KNX and vice versa;

WAN connection between KNX systems (where an installed KNX system is at least one line);

an interface to super ordinate building management and energy management systems.

A KNXnet/IP system contains at least these elements:

one EIB line with up to 64 (255) EIB devices;
OR
one KNX segment (KNX-TP1, KNX-RF, KNX-PL110);

a KNX-to-IP network connection device (called KNXnet/IP server);

and typically additional

software for remote functions residing on e.g. a workstation (may be data base application, BACnet Building Management System, browser, etc.).

Figure 1 shows a typical scenario where a KNXnet/IP client (e.g. running ETS) accesses multiple KNX installed systems or KNX subnetworks via an IP network. The KNXnet/IP client may access one or more KNXnet/IP servers at a time. For subnetwork, routing server-to-server communication is possible.

This document specifies the procedure for the determination of total shrinkage of concrete specimens in drying conditions.

NOTE 1       Possible shrinkage or length changes occurring before 24 h of age, and which may have significant amplitude and/or consequences, e.g. for high performance concrete and/or in case of restraint, may need to be measured according to a complementary procedure not covered by the present standard.

NOTE 2       Information on a simplified procedure for the determination of autogenous shrinkage is given in Annex A.

The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 32 mm.

This document provides a means of classifying the performance of opening windows according to their strength in resisting, where appropriate, racking load, static torsion and their operating forces. Special aspects such as those of burglar resistance are not covered. [1])

 

[1])    Effects on other criteria, such as air permeability, are not addressed by prEN 13115.

This document specifies the test method for determining the force required when engaging or releasing the hardware of a window and when commencing the movement of a casement or sash, in both opening and closing directions.

This document is applicable to windows where the movement of the casement or sash is a manual operation.

This document is applicable to products of any frame materiál.

This document describes the procedure for determining the creep (total, autogenous (basic) and drying) of hardened concrete test specimens subjected to a sustained longitudinal compressive load.

The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 32 mm.
