Water quality - Guidance standard on assessing the hydromorphological features of lakes

This document is applicable to lakes, which are water bodies occupying one or more basins with surface areas typically greater than 1 ha (0,01 km2) and maximum depths (at mean water level) greater than 1 m. All types of permanent and temporary lakes, including natural, modified and artificial, freshwater and brackish, except for those systems which regularly connect to the sea, are included in this document. Based on these criteria, it can be estimated that there are at least 500 000 natural lakes across Europe, most of which are located in the glaciated landscapes in northern and western provinces and in Scandinavia. Lakeland districts also occur locally in areas such as large river catchments (e.g. the Danubian plain) and around the Alps. Elsewhere, naturally occurring lakes are relatively sparse and in such areas reservoirs or pits are more common. This document is designed to: a) support environmental and conservation agencies in meeting the monitoring requirements of the WFD (Article 8, Annex II and Annex V); b) generate data sets appropriate for monitoring and reporting of Natura 2000 sites designated under the Habitats Directive and the Birds Directive; c) provide information supporting other environmental reporting requirements (e.g. in relation to biodiversity or environmental impact assessment); d) support lake management and restoration initiatives. This document: e) defines the key term of ‘hydromorphology’ and other terms relating to the morphological characteristics of lakes and their hydrological regimes; f) details essential features and processes of lakes that should be characterized as part of a hydromorphological survey and for determining the hydromorphological condition of a lake; g) identifies and defines the key pressures affecting European lakes; h) provides guidance on strategies for collecting hydromorphological data depending on resources available and the anticipated use of the assessment; a hierarchy of approaches is recognized from the ‘overview method’ utilizing existing databases, maps and remote sensing data through to recognized field-based survey techniques such as Lake Habitat Survey (LHS) [3]; i) offers guidance on data presentation; j) establishes guidance on data quality assurance issues. This document does not deal with biological assessments in lakes such as the presence or absence of individual species or community composition, nor does it attempt to link specific hydromorphological features with their associated biological communities or to create a classification based on such links. However, it is relevant where plants or other organisms form significant structural elements of the habitat (e.g. a gradation from riparian to littoral vegetation). With respect to the WFD, the hydromorphological condition of a lake only contributes to its status classification at high ecological status (HES). Hydromorphological conditions are not defined for good and moderate status but shall be sufficient to support the biological elements. However, some countries are now beginning to classify lakes according to their hydromorphology. The information gathered by using this standard can provide a basis for classification, but this classification is the subject of EN 16870 and not EN 16039.

Test of insulation of bars and coils of high-voltage machines

This document applies to rotating electrical machines with rated voltages (UN) from 5 kV to 27 kV inclusive and with rated output from 5 MVA upwards for generators and from 5 MW upwards for motors. This document is also applicable to machines with rated outputs between 1 MVA (1 MW) and 5 MVA (5 MW) and with rated voltages of 5 kV and above, provided its use has been agreed beforehand. Requirements for machines with a rated voltage above 27 kV are the subject of individual agreement. In the case of machines whose windings are cured in the stator, tests on the separate winding elements are not possible; for these machines the requirements in Clause 6 apply. Converter fed machines are excluded from the scope of this standard. The described tests can be used for this type of machines however the criteria are mutually agreed upon between user and manufacturer.

Laboratory furniture - Recommendations for design and installation - Part 5: Services distribution carriers

This document is applicable to biology, chemistry and physics laboratories where research, preparative, analytical, process activities take place and which can involve work with hazardous substances, including higher education (college and university teaching and post-graduate research). This document does not cover the requirements of schools, i.e. precollege/pre-university (refer to EN 13150), or highly specialist laboratories which need very specific, bespoke solutions to enable them to function. This document specifies requirements for various types of services distribution carriers typically used in combination with laboratory bench types as covered in the EN 14056 series. This document gives guidelines for all parties involved in the planning, design, manufacture, installation, testing of a new laboratory or in the refurbishment of an existing laboratory.
