Vandens kokybė. Ežerų hidromorfologinių charakteristikų vertinimo vadovas

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.

This document specifies procedures for assessment and verification of constancy of performance (AVCP). This document is applicable to roomheaters, inset appliances and cookers which can be fired batchwise in fuel baskets for wood pellets (freestanding manually fuelled intermittent burning appliances). This document is applicable to appliances with fully integrated baskets for wood pellets which are integral component of the appliance. If the appliance is to be fired with wood logs or compressed untreated wood (wood briquettes), the configuration of the combustion chamber can be changed according to the instructions. Different fuels cannot be operated at the same time and they can be tested separately according the relevant part of EN 16510-2-x. The intended use of the appliances is space heating in residential buildings and can be cooking (when tested accordingly). These appliances can be supplied either as an assembled appliance or as a predesigned unit consisting of prefabricated components designed to be built on site in accordance with the specified assembly instructions. They only operate with the firedoors closed. This document is not applicable to: - mechanically fed appliances; - appliances with fan assisted combustion air; - appliances with boiler.

Organinės ir organinės-mineralinės trąšos. Tam tikrų parametrų nustatymas

This document specifies references to the methods for the determination of the following parameters in organic and organo-mineral fertilizers: — Determination of the total organic carbon content; — Determination of the dry matter content. The method for the determination of the total organic carbon is not applicable to products containing urea-formaldehyde polymers or urea as long as there is no method available to assess carbon in urea-formaldehyde polymers or urea. The carbon contained in these compounds is not considered organic [1]. The scope of the standards referenced in this document specifies in which cases the method is also applicable to fertilizing product blends.

Organinės ir organinės-mineralinės trąšos. Šešiavalenčio chromo kiekio nustatymas chromatografijos metodu

This document specifies a method for the determination of hexavalent chromium (chromium(VI)) in organic and organo-mineral fertilizers. The method specified is suitable to quantify the chromium(VI) content in organic and organo-mineral fertilizers down to 2 mg/kg dry matter. The results obtained from this method are strictly dependent on the extraction conditions. Results obtained by using other extraction procedures (extraction solution, pH of the extraction solution, extraction time, extraction temperature, etc.) are not comparable with the results produced by the procedure described in this document. This document is applicable to fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants and where organic matter is present in at least one of the products in the blend. In case a fertilizing product blend is composed only of inorganic products, the European Standard for inorganic fertilizers or liming materials applies. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

Perspėjimo apie ekstremaliąsias situacijas ir pavojų sistemos. 3 dalis. Reagavimo į ekstremaliąsias situacijas ir pavojų sistemos. Rizikos valdymo byla ir taikymo pavyzdžiai

This document specifies the structure, construction, content and sequence of a technical risk management process and the technical risk management file in accordance with EN 50726-1. It also describes application examples for technical risk management according to EN 50726-1. An emergency and danger response system (EDRS) is used to minimize risks to life and limb. Its purpose is to report, verify and manage emergencies and dangers in order to prevent or limit personal injury. As already mentioned in the scope of application of EN 50726-1, the implementation of the Occupational Safety and Health Act and the subsequent regulations is intended in order to take particular account of the protection objective defined therein (physical integrity). However, this not only includes a risk assessment (e.g. prevention of acts of violence) for employees, but also for everyone in the property. The requirements of the Occupational Safety and Health Act are therefore intended to be observed when creating a safety concept and as part of the technical risk management process. Consequently, particular attention is drawn to paragraphs 5, 6 and 9 of the Occupational Safety and Health Act. Risks to life and limb can include emergencies and dangerous situations that can cause psychological or physical harm to people. As soon as the top management (e.g. operators, entrepreneurs, companies, approving authorities, building authorities, administrations) of a property has identified such risks to life and limb as part of risk management or similar risk assessments and/or independently became aware of them, this falls within the scope of EN 50726-1.
