Fotovoltinė įranga pastatuose. 1 dalis. Į pastatus integruojami fotovoltiniai moduliai

This document applies to photovoltaic modules that contain at least one glass pane and which are used as construction products. It focuses on the properties of these photovoltaic modules relevant to essential building requirements as specified in the European Construction Product Regulation CPR 305/2011, and the applicable electro-technical requirements as stated in the Low Voltage Directive 2014/35/EU / or CENELEC standards. The CE mark of building integrated photovoltaic (BIPV) modules will thus state properties based on both documents as they are both equally applicable. This document references international standards, technical reports and guidelines. For some mounting categories, in addition, national standards (or regulations) for building products may apply in individual countries, which are not explicitly referenced here and for which harmonized European Standards are not yet available. The document is addressed to manufacturers, planners, system designers, installers, testing institutes and building authorities. This document does not address concentrating or building-attached photovoltaic modules (BAPV). This document addresses requirements on the PV modules in the specific ways they are intended to be mounted. Separable mounting structures are within the scope of EN 50583 2. NOTE For the definition of building-attached photovoltaic modules (BAPV) refer to Clause 3.

This document gives general requirements and tests for residual current operated circuit-breakers with integral overcurrent protection for household and similar uses (hereafter referred to as RCBOs), for rated operational voltages not exceeding 440 V AC, with rated frequencies of 50 Hz, 60 Hz or 50/60 Hz and rated currents not exceeding 125 A and rated short-circuit capacities not exceeding 25 000 A. RCBOs are intended to provide fault protection (previously referred to as protection against indirect contact), the exposed conductive parts of the installation being connected to an appropriate earth electrode. These devices are also intended to protect against overcurrents in the wiring installations of buildings and similar applications. They are also intended to be used to provide protection against fire hazards due to a persistent earth fault current. RCBOs having a rated residual operating current not exceeding 30 mA are used for fault protection and additional protection in the case of failure of the protective provisions against electric shock. This document applies to RCBOs performing simultaneously the functions of detection of the residual current, of comparison of the value of this current with the residual operating value and of opening of the protected circuit when the residual current exceeds this value. These devices also perform the function of making, carrying and breaking overcurrents under specified conditions. RCBOs are intended to be operated by ordinary or uninstructed persons and designed not to require maintenance. The requirements of this document apply for standard conditions (see 7.1). Additional requirements can be necessary for RCBOs used in locations which have severe environmental conditions. RCBOs within the scope of this document are intended for use in an environment with pollution degree 2 (see 7.3). RCBOs are suitable for isolation. Special precautions (e.g. surge protective devices) can be necessary when excessive overvoltages are likely to occur on the supply side (for example in the case of supply through overhead lines, see IEC 60364-4-44 and IEC 60364-5-53). RCBOs, with the exception of those with an uninterrupted neutral, are suitable for use in IT systems. RCBOs of the general type are resistant to current surges, including the case where surge voltages (as a result of switching transients or induced by lightning) cause loading currents in the installation without occurrence of flashover. RCBOs of type S are considered to be sufficiently resistant against unwanted tripping even if the surge voltage causes a flashover and a follow-on current occurs. This document also applies to RCBOs obtained by the assembly of an adaptable residual current device with a circuit-breaker. The mechanical assembly is intended to be effected in the factory by the manufacturer, or on site, in which case the requirements of Annex G apply. It also applies to RCBOs having more than one rated current, provided that the means for changing from one discrete rating to another is not accessible in normal service and that the rating cannot be changed without the use of a tool. Particular requirements are necessary for RCBOs intended to be used at frequencies other than 50 Hz or 60 Hz. For RCBOs incorporated in, or intended for association with socket-outlets only, the requirements of this document can be used, as far as applicable, in conjunction with the requirements of IEC 60884-1 or the national requirements of the country where the product is placed on the market. This document does not apply to: ....

This document describes various corrosion under insulation (CUI) environments in refineries and other related industries and environments, and establishes CUI environmental categories including operating temperature ranges from −45 °C to 204 °C for topside and aboveground service only. This document specifies both established and other test methods for the assessment of coatings used for prevention of CUI for each given environment. This document also provides acceptance criteria for each CUI environment. NOTE The test results and acceptance criteria can be considered an aid in the selection of suitable coating systems. For service or peak temperatures below −45 °C an optional cryogenic test can be incorporated and for over 204 °C testing acceptance criteria can be agreed between interested parties. Additional or other test and acceptance measures are possible, but require particular agreement between the interested parties. This document covers spray-applied coatings applied on new carbon and austenitic stainless steel for use in CUI service. This document does not cover testing of sacrificial coatings, such as inorganic zinc, as these coatings can be consumed quickly in wet environments. Developing accelerated corrosion testing for what can be continuous wet service with sacrificial coatings is beyond the scope of this document. "Non-through porosity" thermal spray aluminium coatings with greater than 250 µm dry film thickness can be tested and qualified in accordance with this document. This document does not cover tape and sheet applied products for use in preventing CUI. This document does not deal with other aspects of coating degradation, such as those caused by abrasion, erosion, ultraviolet degradation or other methods that can exist given specific environment and construction methods.

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.

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.
