This standard forms part 7 of the series ISO 18674, as described in ISO 18674-1: Part 1. The methods of measuring are described and rules for measurement of strain in structural members are given from which stresses can be computed in geotechnical engineering or more general in foundation engineering. Strains and stresses in geotechnical structural members are needed to judge the loading of engineered construction in the ground

The document covers all aspects which are relevant for the design of all kinds of water wells abstracting from or injecting water to the groundwater or for groundwater observation. This document does not apply to horizontal wells and closed loop geothermal systems. The document defines design requirements of water wells for public and private users in accordance with groundwater protection goals. It gives guideline for all planning steps from preliminary to final executive project design. This document specifies a sequential method for designing a well. Based on the hydrogeological conditions and the objectives of the well, a step-by-step process of dimensioning the well is defined. This methodology includes dimensioning of the drilling, filter packs, sealing and screen. Furthermore, selection of appropriate materials, the pump and all other additional well equipment is established. With regard to the planning process references are provided to drilling methods, geophysical well logging, well development and pumping tests.

This document, together with prEN 13476 1, specifies the definitions and requirements for pipes, fittings and the system based on unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) structured-wall piping systems that are intended for use in non-pressure underground drains and sewers for foul wastewater. NOTE 1 Products complying with this document can also be used in non-pressure underground drains and sewers for surface water. This document is applicable to pipes and fittings with smooth internal and external surfaces, designated as Type A. This document also specifies test methods and test parameters. This document is applicable to: a) structured-wall pipes and fittings, which are intended to be used buried underground outside the building structure; reflected in the marking of products by “U”; b) structured-wall pipes and fittings, which are intended to be used buried underground both outside (application area code “U”) and within the building structure, reflected in the marking of products by “UD”. This document is applicable to structured-wall pipes and fittings with or without an integral socket with elastomeric ring seal joints as well as welded and fused joints. This document covers a range of pipe and fitting sizes, materials, pipe constructions, stiffness classes, application areas, tolerance classes and gives recommendations concerning colours. NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

This document, together with prEN 13476-2 and prEN 13476-3, specifies the definitions and general requirements for pipes, fittings and the system based on unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) structured-wall piping systems that are intended for use in non-pressure underground drains and sewers for foul wastewater. NOTE 1 Products complying with this document can also be used in non-pressure underground drains and sewers for surface water. This document is applicable to: a) structured-wall pipes and fittings, which are to be used buried in the ground outside a building structure only; reflected by the marking of products by “U”; b) structured-wall pipes and fittings, which are to be used buried in ground both outside (application area code “U”) and within a building structure (application area code “D”); reflected in the marking of products by “UD”. In conjunction with prEN 13476-2 and prEN 13476-3, it is applicable to structured-wall pipes and fittings with or without an integral socket with elastomeric ring seal joints, as well as welded and fused joints.

This part specifies general aspects and gives guidance concerning a national selection of requirement levels and classes where part 2 and part 3 of this standard provide options. prEN 13476-2 and prEN 13476-3 specify material characteristics, dimensions and tolerances, test methods, test parameters and requirements for pipes with smooth internal and external surfaces, Type A, and pipes with smooth internal and profiled external surfaces, Type B. This document, together with prEN 13476-2 and prEN 13476-3, covers a range of pipe and fitting sizes, materials, pipe constructions, stiffness classes and tolerance classes and offers recommendations concerning colours.

NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. NOTE 3 Pipes, fittings and other components conforming to any plastic product standards referred to in Clause 2 can be used with pipes and fittings conforming to this standard, when they conform to the requirements for joint dimensions given in part 2 and part 3 of this standard and to the performance requirements given in Clause 9.
