Construction

This part of EN 13924 provides a framework for specifying the properties and relevant test methods for hard paving grade bitumens which are suitable for use in the construction and maintenance of roads, airfields and other paved areas.

This International Standard is intended for the measurement of the air permeability of buildings or parts of buildings in the field. It specifies the use of mechanical pressurization or depressurization of a building or part of a building. It describes the measurement of the resulting air flow rates over a range of indoor-outdoor static pressure differences.

This International Standard is intended for the measurement of the air leakage of building envelopes of single-zone buildings. For the purpose of this International Standard, many multi-zone buildings can be treated as single-zone buildings by opening interior doors or by inducing equal pressures in adjacent zones.

It does not address evaluation of air permeability of individual components.

This European standard specifies the requirements and test methods for draught regulators and standstill opening devices that are used as components, carrying flue gases, in order to limit the draught in chimneys and provide secondary air to the chimney.

Draught regulators and standstill opening devices for positive pressure chimneys are not covered by this standard.

It also specifies the requirements for marking, manufacturers’ instruction, product information and evaluation of conformity.

Definition, requirements and testing of additional functionalities for water meters in combination with Additional Functionality Devices (AFD) as standardised in part 1 of the EN 14154 in response to EU/EFTA Mandate M/441 EN.

This standard applies to AFDs that are installed in locations with vibration and shocks of low significance and in:

—       closed locations (indoor or outdoor with protection as specified by the manufacturer) with condensing or with non-condensing humidity;

or, if specified by the manufacturer:

—       open locations (outdoor without any covering) with condensing humidity or with non-condensing humidity;

—       locations liable to temporary saturation,

and in locations with electromagnetic disturbances corresponding to those likely to be found in residential, commercial buildings or similar buildings.

This standard does not cover the changing of metrological software within the meter or the upload/download of metrological software.

This part of ISO 6781 specifies the qualifications and an assessment process for personnel who (i) perform thermographic investigations on buildings (ii) who interpret the data emanating from thermographic investigations, and (iii) who report the results of thermographic investigations.

This standard provides the basis for a declaration of conformity, in three classes, of the knowledge, skills and abilities of individuals to perform thermographic measurements, analysis and reporting of results for residential, commercial and institutional buildings.

Specialized equipment or other specific situations is not covered by this standard.

This European Standard provides specifications for the two types of variable message signs (VMS); i.e. continuous (see 3.4) and discontinuous (see 3.6).

This European Standard specifies visual and physical characteristics of VMS as well as their durability aspects. It also provides relevant requirements and corresponding test methods, evaluation of conformity and marking.

This European Standard covers VMS used in circulation areas, on public, private land, including tunnels for the information, guidance, warning and/or direction. Test modules are used to demonstrate compliance with the requirements.

This European Standard covers membranes, individual substructure components, substructure kits and suspended ceiling kits intended to be placed on the market. It covers suspended ceilings sold as a complete kit, substructures placed on the market as kits, individual components (products) of such substructures, and membrane components. It includes test methods and methods of assessment, as well as provisions for the evaluation of conformity and for the marking of the products to the requirements of this European Standard.

In the absence of any other European Standard, this European Standard specifies dimensions, tolerances and, where relevant, performance requirements, for commonly available ceiling substructures and membrane components.

This European Standard covers the following characteristics:

—       reaction to fire;

—       fire resistance (suspended ceiling kits only);

—       release and/or content of dangerous substances:

—      release of asbestos (content) (suspended ceiling kits and membrane components only);

—      release of formaldehyde (suspended ceiling kits and membrane components only);

—      other dangerous substances;

—       shatter properties (safe breakage)/impact resistance (for suspended ceiling kits and membrane components of brittle materials in suspended ceiling kits only);

—       flexural tensile strength;

—       load bearing capacity, tolerances and dimensions;

—       electrical safety (as adequacy of the product to avoid electrocution from installations that may be part of the assembled ceiling, using electricity, such as ventilation devices and lighting);

—       direct airborne sound insulation (suspended ceiling kits only);

—       sound absorption (suspended ceiling kits and membrane components only);

—       thermal conductivity (suspended ceiling kits and membrane components only);

—       susceptibility to the growth of harmful micro-organisms;

—       resistance to fixings (relevant for components that are mechanically fixed);

—       durability of flexural tensile strength and load bearing capacity against moisture.

This European Standard also covers the following requirements:

—       colour and light reflectance;

—       installation.

This European Standard does not cover the following:

—       ceiling substructures and membrane component covered by other harmonised European Standards, for in-situ formed ceilings, covered by other European technical specifications, for which it is the installer, not the component manufacturer, who takes responsibility for ensuring that the complete installed suspended ceiling meets any regulatory requirements to which it is subject;

—       stretched ceilings covered by EN 14716;

—       ceilings in mobile buildings, caravans and other forms of transportation;

—       characteristics needed for special applications, for which additional characteristics other than covered by this European Standard would need to be complied with;

—       suspended ceilings intended for uses in ceilings subject to water penetration requirements

—       ceilings used externally where requirements other than covered by this standard would apply (tunnels, canopies, petrol stations, arcades, open sports facilities, car parks etc.);

—       heavy duty suspended ceilings or their supporting construction (e.g. ceilings that can be walked on);

—       ceilings made from fire protective boards;

—       the performance and health and safety requirements of light fittings and other features that, optionally, are included in the suspended ceiling;

—       panels from materials covered in other harmonised European standards already prepared by CEN/TC 241 and CEN/TC 112 (see NOTE 2)

—       anchors covered by other European technical specifications.

NOTE 1       These standards have been developed by CEN/TC 241 under the Mandate M/106 “Gypsum products” and by CEN/TC 112 under the Mandate M/113 “Wood-based panels”.

This European Standard also gives certain specifications for the installed suspended ceiling system (see NOTE 1).

NOTE 2          There are two reasons for this:

—        the individual components and kits may have to meet certain requirements in order for the installed system to be able to meet the requirement when the system is installed, and

—        it is appropriate, for ease of reference, to give both component/kit requirement and installed system requirement in the same document, given the relationship between them.

This European Standard provides information for the various parties responsible for designing, manufacturing and specifying/selecting suspended ceilings used for interior applications in general building and civil engineering structures.

This part of EN 1253 specifies requirements for the design, construction, performance, application and marking as well as test methods of factory made roof drains and floor gullies without trap (further: floor gullies) for buildings.

This European Standard does not apply to trapped floor gullies with a depth of water seal of at least 50 mm as specified in prEN 1253-1.

This part of EN 1253 classifies floor gullies for use inside buildings, gives guidance for places of installation and specifies requirements for the construction, design, performance and marking of factory made gullies for buildings, irrespective of the material, for use in drainage systems requiring a trap with a depth of water seal of at least 50 mm (further: floor gullies).

Although normally used to convey domestic wastewater and industrial wastewater, these floor gullies may convey other wastewater provided there is no risk of damage to components or of injury to health.

This European Standard does not apply to

—       linear drainage channels as specified in EN 1433,

—       gully tops and manhole tops which are specified in EN 124,

—       roof drains and floor gullies without trap as specified in prEN 1253‑2.

This document deals with the equipment requirements, execution of and reporting of the determination of the bulk density of soils.

NOTE 1    This document fulfils the requirements of the determination of the bulk density of soils for geotechnical investigation and testing in accordance with EN 1997-1 and EN 1997-2.

NOTE 2    If required, the dry density of a specimen may be calculated from the bulk density and the water content, if known.

The bulk density of a soil is useful in the determination of the in-situ overburden stresses at various depth (geostatic stresses). Furthermore, bulk and dry density can qualitatively describe the mechanical characteristics of a soil via empirical relationships which are to be found in the technical literature. Such relationships should be used only as guidelines and should be supplemented by direct measurements of the mechanical characteristics.

This document describes three methods:

a)     linear measurement method;

b)    immersion in fluid method;

c)     fluid displacement method.

The linear measurement method is suitable for the determination of the bulk density of a specimen of soil of regular shape, including specimens prepared for other tests. The specimens used are either rectangular or cylindrical prisms.

The immersion in fluid method covers the determination of the bulk density of a specimen of natural or compacted soil by measuring its mass in air and its apparent mass when suspended in fluid. The method may be used when lumps of material of suitable size can be obtained.

The fluid displacement method covers the determination of the bulk density of a specimen of soil by measuring its mass in air and the mass of fluid displaced by immersion. The method may be used when lumps of material of suitable size can be obtained.

NOTE Ideally, test specimens should be at least 50 cm³ in volume, and preferably significantly larger, otherwise the uncertainty of the reported result may not be in accordance with the reporting requirements of this document. 

This document deals with the equipment requirements, execution of and reporting of the determination of water content in soils.

NOTE This document fulfils the requirements of the determination of water content of soils for geotechnical investigation and testing in accordance with EN 1997-1 and EN 1997-2.

This document specifies the laboratory determination of the water (also known as moisture) content of a soil test specimen by oven-drying within the scope of geotechnical investigations. The water content is required as a guide to the classification of natural soils and as a control criterion in re-compacted soils, and is measured on samples used for most field and laboratory tests. The oven-drying method is the definitive procedure used in usual laboratory practice.

The practical procedure for determining the water content of a soil is to determine the mass loss on drying the test specimen to a constant mass in a drying oven controlled at a given temperature. The mass loss is assumed to be due to free water and is referenced to the remaining dry mass of solid particles.

1.1 This European standard specifies the general requirements for the construction, performance and safety of ball valves and closed bottom taper plug valves. It also details the test methods and marking requirements.

It applies to metallic valves for domestic and commercial not directly buried installations inside or outside of buildings, using gases of the first, second and third family (specified in EN 437) and working up to

0,2 · 10⁵ Pa, 0,5 · 10⁵ Pa, 1 x 10⁵Pa. 5 · 10⁵ Pa and 20 x 10⁵Pa.

NOTE          "Not directly buried" within the context of this standard means that valves below ground are not in direct contact with earth or other materials e.g. that they are in a protected encasement.

1.2 Valve nominal sizes (DN) covered by this European standard are as follows: 6, 8, 10, 12, 15, 20, 25, 32, 40, 50.
