This document establishes the specifications for the execution of static pile load tests in which a single pile is subjected to an axial static load in tension in order to define its load-displacement behaviour. This document is applicable to vertical piles as well as raking piles. All types of piles are covered by this document. The tests considered in this document are limited to maintained load tests. Cyclic load tests are not covered by this document. NOTE This document is intended to be used in conjunction with EN 1997-1. EN 1997-1 provides numerical values of partial factors for limit states and of correlation factors to derive characteristic values from static pile load tests to be taken into account in design. This document provides specifications for the execution of static axial pile load tests: a) checking that a pile will behave as designed; b) measuring the resistance of a pile.

This document specifies: - general requirements for water supply systems outside buildings including potable water mains and service pipes, service reservoirs, other facilities and raw water mains but excluding treatment works and water resources development; - general requirements for components; - general requirements for inclusion in product standards which may include specifications which are more stringent; - requirements for installation, site testing and commissioning. The requirements of this document apply to: - the design and construction of new water supply systems; - the extension of significant areas forming a coherent part of an existing water supply system; - significant modification and/or rehabilitation of existing water supply systems; - all those water infrastructure systems since they are key to meet the sustainable goals of the cities and to show the urgent need to invest in them in order to consider fundamental aspects, such as resilience or mitigation/adaptation to climate change. NOTE It is not intended that existing water supply systems are to be altered to comply with this document, provided that there are no significant detrimental effects on water quantity, security, reliability and adequacy of the supply.
