This standard is part 8 of the series ISO 18674, as described in ISO 18674-1: Part 1. General rules for the methods and rules for measurement of normal forces and loads from tieback, bracing, struts and other elements like piles in geotechnical engineering or more general in foundation engineering are given

This European Standard specifies the requirements and gives recommendations for the design, sizing, installation, identification, commissioning and maintenance of rainwater harvesting systems for the use of rainwater on-site as non-potable water. This European Standard also specifies the minimum requirements for these systems. Excluded from the scope of this European Standard are: - the use as drinking water and for food preparation; - the use for personal hygiene purposes; - decentralized attenuation; - infiltration. NOTE Conformity with the standard does not exempt from compliance with the obligations arising from local or national regulations.

1.1 Scope of prEN 1997-1 (1) This document provides general rules for the design and verification of geotechnical structures. (2) This document is applicable for the design and verification of geotechnical structures outside the scope of prEN 1997-3:2022. NOTE In this case, additional or amended provisions can be necessary. 1.2 Assumptions (1) In addition to the assumptions given in prEN 1990:2021, the provisions of prEN 1997:2022 (all parts) assume that: - ground investigations are planned by personnel or enterprises knowledgeable about potential ground and groundwater conditions; - ground investigations are executed by personnel having appropriate skill and experience; - evaluation of test results and derivation of ground properties from ground investigation are carried out by personnel with appropriate geotechnical experience and qualifications; - data required for design are collected, recorded, and interpreted by appropriately qualified and experienced personnel; - geotechnical structures are designed and verified by personnel with appropriate qualifications and experience in geotechnical design; - adequate continuity and communication exist between the personnel involved in data-collection, design, verification and execution. (2) This document is intended to be used in conjunction with prEN 1990:2021, which establishes principles and requirements for the safety, serviceability, robustness, and durability of structures, including geotechnical structures, and other construction works. (3) This document is intended to be used in conjunction with prEN 1997-2, which gives provisions rules for determining ground properties from ground investigations. (4) This document is intended to be used in conjunction with prEN 1997-3, which gives specific rules for the design and verification of certain types of geotechnical structures. (5) This document is intended to be used in conjunction with the other Eurocodes for the design of geotechnical structures, including temporary geotechnical structures.

1.1 Scope of prEN 1997-3 (1) This document provides specific rules to be applied for design and verification of geotechnical structures. 1.2 Assumptions (1) This document is intended to be used in conjunction with prEN 1990:2021, which establishes principles and requirements for the safety, serviceability, robustness, and durability of structures, including geotechnical structures, and other construction works. (2) This document is intended to be used in conjunction with prEN 1997-1:2022, which provides general rules for design and verification of geotechnical structures. (3) This document is intended to be used in conjunction with prEN 1997-2:2022, which gives provisions rules for determining ground properties from ground investigation. (4) This document is intended to be used in conjunction with the other Eurocodes for the design of geotechnical structures, including temporary geotechnical structures.

1.1 Scope of prEN 1997-2 (1) This document provides rules for determining ground properties for the design and verification of geotechnical structures. (2) This document covers guidance for planning ground investigations, collecting information about ground properties and groundwater conditions, and preparation of the Ground Model. (3) This document covers guidance for the selection of field investigation and laboratory test methods to obtain derived values of ground properties. (4) This document covers guidance on the presentation of the results of ground investigation, including derived values of ground properties, in the Ground Investigation Report. 1.2 Assumptions (1) The provisions in prEN 1997-2:2022 are based on the assumptions given in prEN 1990:2021 and prEN 1997-1:2022. (2) This document is intended to be used in conjunction with prEN 1997-1:2022, which provides general rules for design and verification of all geotechnical structures. (3) This document is intended to be used in conjunction with prEN 1997-3:2022, which provides specific rules for design and verification of certain types of geotechnical structures. (4) This document is intended to be used in conjunction with prEN 1998-1-1 which provides the requirements for the ground properties needed to define the seismic action. (5) This document is intended to be used in conjunction with prEN 1998-5 which provides rules for the design of geotechnical structures in seismic regions.
