It applies to metallic valves not directly buried for domestic and commercial 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 × 105Pa, 5 × 105 Pa and 20 × 105Pa and with temperature limits from -5 °C or −20 °C to + 60 °C.
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.

This European Standard specifies the requirements and test methods for adhesives used for joining the components of unplasticised poly(vinyl chloride) (PVC-U), chlorinated poly(vinyl chloride)(PVC-C), acrylonitrile -butadiene-styrene (ABS) and styrene copoly¬mer blends (PVC+SAN) thermoplastic piping systems for fluids under zero pressure (e.g. soil and waste discharge), independent of the application area.
It provides reference for the evaluation of conformity of the adhesive to this European Standard.

This document defines wood-based panels for use in construction and specifies the relevant characteristics and the appropriate test methods to determine these characteristics for wood-based panels, unfaced, overlaid, veneered or coated:
-   for internal use as structural components in dry conditions ) ;
-   for internal (or protected external) use as structural components in humid conditions ) ;
-   for external use as structural components ) ;
-   for internal use as non-structural components in dry conditions1);
-   for internal (or protected external) uses as non structural components in humid conditions2);
-   for external use as non-structural components3);
-   for use as structural floor decking on joists in dry1) or humid2) or external3) conditions;
-   for use as structural roof decking on joists in dry1) or humid2) or external3) conditions;
-   for use as structural wall sheathing on studs in dry1) or humid2) or external3) conditions.
   It provides for the evaluation of conformity and the requirements for marking these products.
This document covers wood-based panels in the form of solid wood panels, LVL ) , plywood, OSB, particleboards (chipboards) either resin- or cement-bonded, wet process fibreboards (hardboards, medium boards, softboards) and dry process fibreboards (MDF) for use in construction. They may contain chemical agents to improve their reaction to fire and their resistance to biological attack, e.g. by fungi and insects.
This document is not intended to be applicable to wood-based panels for use in non-constructional applications.

This Standard specifies the performance requirements for flexible couplings, bushes and adaptors for use with pipes and fittings in drainage and sewerage systems, normally operated under gravity, both above and below ground and intended to connect different pipes for:
- Repair of damaged pipelines,
- Connecting pipes of different materials and/or diameters,
- Jointing short/cut lengths of pipe,
- Jointing specific pipe systems,
- Jointing post-inserted preformed junctions.
Typically a coupling consists of a moulded or extruded flexible sleeve with two clamping bands with or without a shear band. The clamping bands enable the sleeve to form a seal with the pipes to be joined. The shear band gives resistance to shear forces. Connections
may be made between pipes which cannot be satisfactorily joined by a coupling alone, of dissimilar sizes or material, by using an appropriate bush or bushes with the coupling.

This European Standard specifies the performance requirements for flexible couplings and adaptors and bushes for use with pipes and fittings in drain and sewer systems, usually operated under gravity and periodic hydraulic surcharge, both above and below ground inside or outside buildings and intended to connect pipes for:
-   repair of damaged pipelines;
-   connecting pipes of different materials and/or diameters;
-   jointing short/cut lengths of pipe;
-   jointing specific pipe systems;
-   jointing post-inserted preformed junctions.
Typically a coupling consists of a moulded or extruded flexible sleeve with two clamping bands with or without a shear band. The clamping bands enable the sleeve to form a seal with the pipes to be jointed. The shear band gives resistance to shear forces. Connections may be made between pipes which cannot be satisfactorily jointed by a coupling alone, of dissimilar sizes or material, by using an appropriate bush or bushes with the coupling or by using an appropriate adaptor.

This European Standard specifies the materials and dimensions for metal banded flexible couplings and adaptors and bushes for use with pipes and fittings in drain and sewer systems, usually operated under gravity and periodic hydraulic surcharge, both above and below ground inside or outside buildings and intended to connect pipes for:
-   repair of damaged pipelines;
-   connecting pipes of different materials and/or diameters;
-   jointing short/cut lengths of pipe;
-   jointing specific pipe systems;
-   jointing post-inserted preformed junctions.
The coupling consists of a moulded or extruded rubber sleeve with two stainless steel clamping bands with or without a stainless steel shear band. The clamping bands enable the sleeve to form a seal with the pipes to be joined. The shear band gives resistance to shear forces. Connections may be made between pipes which cannot be satisfactorily joined by a coupling alone, of dissimilar sizes or material, by using an appropriate bush or bushes with the coupling or by using an appropriate adaptor.
