DIN EN ISO 4375:2015-03

This International Standard defines the requirements for equipment, anchorage, supports and accessories for cableway systems for use in stream gauging. Systems which are operated either entirely from the river bank or from a suspended personnel carriage (also called a "cable car") are discussed. This standard is only applicable to the cableway systems to be used for hydrometric measurements. This International Standard does not concern methods for making a discharge measurement which are described in ISO 748. The aim of the revision of this standard is the improvement of the user-friendliness. Therefore the maintenance requirements were supplemented and described in a more practical way. Furthermore, the calculation formulas and tables for cableway characteristics have been revised and supplemented. In addition, another informative Annex "Limiting main cable tension in bankside cableways" has been added to describe safety factors and possibilities for modernization and conversion of existing installations for which the design records are incomplete. The document (EN ISO 4375:2014) has been prepared by Technical Committee ISO/TC 113 "Hydrometry" in collaboration with Technical Committee CEN/TC 318 "Hydrometry", the secretariat of which is held by BSI (United Kingdom). The responsible German committee is NA 119-06-10 AA "Hydrometrie" ("Hydrometry") at the Water Practice Standards Committee at DIN, the German Institute for Standardization e. V.
