This document:

a)     specifies minimum performance and durability and requirements for infill materials used in synthetic turf, and textile sports surfaces;

b)    describes how the performance of an infill is to be measured, and the results classified;

c)     specifies the physical and chemical properties of an infill that are to be declared in a manufacturer’s product declaration;

d)    specifies minimum production control tolerance to ensure consistency of infill materials between production batches;

e)     describes how reclaimed infill is to be tested to assess its suitability for reuse.

NOTE 1       The sports performance characteristics of a synthetic turf or textile sports surface are provided by the combined characteristics of the synthetic turf or textile surface, any infill within the playing surface pile and any shockpad. The selection of the correct permutations of each is complex and the responsibility of the sports surface designer.

NOTE 2       If infill materials migrate from a synthetic turf or textile sports surface into the surrounding natural environment, they become a source of contamination. To minimize the risk this occurring, guidance on how to prevent infill migration from the sports facility is given in CEN Technical Report PD CEN/TR 17519.

This document specifies one method for the desalination by poultices of porous inorganic materials constituting cultural heritage. The desalination methodology can be applied to salt-loaded porous inorganic materials either affected by salt weathering and/or to allow conservation treatments incompatible with soluble salt(s) contamination, or to prevent salt damage where contamination is known to be present. In all cases the desalination aims to decrease salt content.

Furthermore, this document gives the fundamental requirements for the desalination operation and guidelines for the choice of the most appropriate poultice components according to the characteristics of the substrate and types/quantities of salt(s) present in order to optimize the desalination process.

This document describes the functional requirements for pipelines for maximum operating pressure over 16 bar. This document also describes the mechanical requirements for pipework in stations with a maximum operating pressure greater than 16 bar.

NOTE          Welding requirements are described in EN 12732. Functional requirements for stations are given in EN 1776, EN 1918‑5, EN 12186, and EN 12583.

This document is applicable for transporting gas via onshore high-pressure steel pipeline infrastructures, where the following applies:

—    onshore:

•      from the point where the pipeline first crosses what is normally accepted as battery limit between onshore and offshore, and that is not located within commercial or industrial premises as an integral part of the industrial process on these premises except for any pipelines and facilities supplying such premises;

•      pipeline system with a starting point onshore, also when parts of the pipeline system on the mainland subsequently cross fjords, lakes, etc.

—    high pressure: gas with a maximum operating pressure over 16 bar and a design temperature between −40 °C and 120 °C.

—    steel pipeline infrastructure: infrastructure consisting of pipeline components, such as pipes, valves, couplings and other equipment, restricted to components made of unalloyed or low alloyed carbon steel and joined by welds, flanges or mechanical couplings.

—    gas: non-corrosive natural gas, biomethane gas, hydrogen gas and mixtures of these gases where technical evaluation has ensured that operating conditions or constituents or properties of the gas do not affect the safe operation of the pipeline.

Gas infrastructures covered by this document begin after the gas producer's metering station. The functional demarcation of the pipeline system within a plant area is usually directly after the first isolating valve of the installation, but can differ in particular situations.

A schematic representation of pipelines for gas infrastructure is given in Figure 1.

This document can also be applied to the repurposing of existing pipelines.

Scope of prEN 1998-5

(1)         This document establishes general principles for the design and assessment of geotechnical systems in seismic regions. It gives general rules relevant to all families of geotechnical structures, to the design of foundations, retaining structures and underground structures and complements EN 1997-3 for the seismic design situation.

(2)         This document contains the basic performance requirements and compliance criteria applicable to geotechnical structures and geotechnical systems in seismic regions.

(3)         This document refers to the rules for the representation of seismic actions and the description of the seismic design situations defined in EN 1998-1-1 and provides specific definition of the seismic action applicable to geotechnical structures.

Assumptions

(1)         The general assumptions of prEN 1990:2021, 1.2, are assumed to be applied.

(2)         The provisions of this Standard assume that the parties of the project in charge of the analyses, for assessment and possible design of the retrofitting of existing geotechnical structures, have appropriate experience of the type of structures being strengthened or repaired.

This document is applicable to the design and verification of buildings and other structures in seismic regions. It gives general rules relevant to all types of structures, with the exception of special structures.

NOTE   Special structures belong to consequence class CC4, which is not fully covered by the Eurocodes. The categories of structures of consequence class CC4 where EN 1998, or parts of it, apply in a country can be provided by the relevant Authorities or can be found in the National Annex.

This document provides basic performance requirements and compliance criteria applicable to buildings and civil engineering works in seismic regions.

This document gives rules for the representation of seismic actions and the description of the design seismic situations. Certain types of structures, dealt with in other parts of EN 1998, need supplementary rules which are given in those relevant Parts.

This document contains general methods for structural analysis and verification under seismic actions, including base-isolated structures and structures with distributed dissipative systems.

This document 1 contains rules for modelling and verification of ultimate strengths and deformations.

Assumptions

The general assumptions of prEN 1990:2021, 1.2, are supplemented as given in (2) to (6).

It is assumed that no change in the structure and in the masses carried by the structure will take place during the construction phase or during the subsequent life of the structure with respect to the design unless proper justification and verification is provided. This applies to ancillary elements as well (see 3.1.2). Due to the specific nature of the seismic response, this applies even in the case of changes that lead to an increase of the structural resistance.

The design documents are assumed to indicate the sizes, the details and the properties of the materials of the structural members. If appropriate, the design documents are also assumed to include the properties of special devices to be used and the distances between structural and ancillary elements. The necessary quality control provisions are assumed to be specified.

Members of special structural importance requiring special checking during construction are assumed to be identified on the design documents. In this case, the verification methods to be used are also assumed to be specified.

In case of high seismic action class (4.1.1(4)), formal quality system plans, covering design, construction, and use, additional to the control procedures prescribed in the other relevant Eurocodes, are assumed to be specified.
