This document is applicable to the trenchless construction, trenchless replacement techniques and testing of new drains and new sewers in the ground usually operating as gravity or pressure pipelines, formed using prefabricated pipes and their joints. Renovation techniques for existing pressure and non-pressure systems are not covered by this document. Methods of trenchless construction include: - manned and unmanned techniques; - steerable and non-steerable techniques. Mining or tunnelling (e.g. in situ construction or the use of prefabricated segments) are not covered by this document although some parts may apply to these methods. Requirements for associated pipeline installation work other than trenchless construction, e.g. for manholes and inspection chambers, are not covered by this document and are specified in EN 1610. This also applies to pipes that are subsequently installed within entry and exit shafts/pits.

This European Standard specifies the minimum requirements for measuring systems fitted on Track Construction and Maintenance Machines to give an evaluation of track geometry quality when they measure any one or more of the parameters described in EN 13848-1. This European Standard also gives the acceptable differences from EN 13848-1 when using chord measurements. This European Standard does not specify: - requirements for vehicle acceptance; - criteria for track works acceptance; - requirements for Urban Rail Systems. However, parts of it can be used as a reference until a specific Standard is published. Only systems put into service after the standard comes into force are concerned.

This part of EN 16432 specifies the methods for the implementation of ballastless track system designs and the criteria for the acceptance of works concerning construction of ballastless track systems. It does not include any criteria for inspecting, maintaining, repairing and replacing ballastless track systems during operation.
