It also specifies general requirements for components used in hydraulically and pneumatically pressurized pipes, drains and sewers.

NOTE 1       Where the term “inside buildings” is used in the context of components fixed inside buildings, it also includes pipes and fittings fixed on external surfaces of buildings.

NOTE 2       This document is not a product standard and therefore not intended for the direct evaluation of products.

This document covers components to be used in conveying in a satisfactory manner:

—    domestic wastewater;

—    rainwater and surface water; and

—    other wastewater acceptable for discharge into the system.

This document is applicable to components of circular and other cross sections.

This document is equally applicable to components which are factory-made and to those constructed on site, where applicable.

NOTE 3       This document does not apply to components used for trenchless construction according to EN 14457 and for components used for renovation of drains and sewers according to EN 13380.

This document describes the specific functional requirements for the design, construction, operation, maintenance and disposal activities for safe and secure gas compressor stations.

This document applies to new gas compressor stations with a Maximum Operating Pressure (MOP) over 16 bar and with a total shaft power over 1 MW. For existing compressor stations, this document applies to new compressor units. Where changes/modifications to existing installations or gas composition take place, due account can be taken of the requirements of this document.

This document does not apply to gas compressor stations or compressor units operating prior to the publication of this document. For existing sites this document can be used as guidance.

The purpose of this document is to:

—    ensure the health and safety of the public and all site personnel,

—    cover environmental issues,

—    avoid incidental damage to nearby property, and

—    open the gas infrastructure to accommodate renewable gases, including a possible design for hydrogen.

This document specifies common basic principles for the gas infrastructure. Users of this document are expected to be aware that more detailed national standards and/or codes of practice can exist in the CEN member countries.

This document is intended to be applied in association with these 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 document, the national legislation/regulation takes precedence 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.

This document does not apply to:

—    off-shore gas compressor stations;

—    gas compressor stations for compressed gas filling-stations;

—    customer installations downstream of the point of custody transfer;

—    design and construction of driver packages (see Annex C);

—    mobile compressor equipment.

For supplies to utility services such as small central heating boilers reference is made to EN 1775.

Figure 1 shows a schematic representation of compressor stations in a gas infrastructure. For further information refer to Annexes A, B, C, D, E and F.

This document applies to all liquid-applied water impermeable products, based on polymer modified cementitious mortars, dispersions and reaction resin coatings, used beneath ceramic tiling, for external tile installations on walls and floors and in swimming pools.

This document specifies the test methods and the requirements for the non-harmonized characteristic and the designation and marking of liquid-applied water impermeable products beneath ceramic tiling.

This document does not contain recommendations for the design and installation of ceramic tiles and grouts in combination with water impermeable products.

NOTE          Liquid-applied water impermeable products are also used beneath other types of tiles (natural and agglomerated stones, etc.), where they do not adversely affect these materials.

This European Standard has two parts.

Part 1 specifies four methods for the determination of the vertical water infiltration rate of different types of sports surfacing.

Method A is suitable for measuring the vertical water infiltration rate of synthetic, textile and synthetic turf sports surfaces in the laboratory.

Method B is suitable for on-site measurements of the Vertical Water Infiltration Rate of synthetic, textile, synthetic turf and bound mineral sports surfaces.

Method C is suitable for on-site measurements of the vertical water infiltration rate of natural turf sports surfaces.

Method D is suitable for measuring the for on-site measurements of the vertical water infiltration rate of unbound mineral sports surfaces.

NOTE            For filled synthetic turf and unbound mineral surfaces, laboratory tests are considered to give a more precise indication of how a surface will perform.

Part 2 specifies a method for determining the horizontal water flow rate of synthetic, textile and synthetic turf surfaces in the laboratory.
