ČSN P CEN/TS 17152-4 Plastové potrubní systémy pro netlakové podzemní rozvody a skladování nepitné vody - Nádrže používané pro infiltraci, útlum a skladovací systémy - Část 4: Návod na navrhování konstrukce modulárních systémů
Obsah
ČSN P CEN/TS 17152-4 This document gives guidance on the structural design of underground modular systems for infiltration, attenuation and storage of surface water under various conditions of loading. The procedures are explained, with the appropriate variables in the design formulae, and provides graphical information on vehicle surcharge loadings. These modular systems are constructed from multiple cuboid shaped thermoplastic boxes generally with ancillary components such as inlet/outlet connectors, vents, and access/inspection provision. This guidance is for the design of modular systems conforming to EN 17152-1. The boxes, including integral components, are injection moulded, extruded or thermoformed thermoplastics, manufactured from polypropylene (PP) or unplasticized poly(vinyl chloride) (PVC-U), and are intended to be used as elements in a modular system where the manufacturer has clearly stated in the documentation how the components are assembled to create a complete infiltration, attenuation or storage system. Outside the scope of this document are the following conditions: - seismic loads; - lateral loads from adjacent structures and embankments; - influence of trees; - backfill materials not according to CEN/TR 17179 [1]. Geotextile and/or geomembrane used with modular systems are outside the scope of this document. NOTE - If reference is made in this document to Eurocode standards, the conditions in a national foreword or national annex are normally stated.

Obsah
ČSN EN 14620-5 This document is applicable to the design and manufacture of site built, vertical, cylindrical, flat-bottomed tank systems for the storage of refrigerated, liquefied gases with operating temperatures between 0 °C and -196°C. It specifies the requirements for testing, drying, purging, cool-down and decommissioning of refrigerated liquefied gas storage tank systems. The tank systems covered by this document are used to store large volumes of hydrocarbon products, ammonia and other non-hydrocarbon gases with low temperature boiling points, generally called "Refrigerated Liquefied Gases" (RLGs). Typical products stored in the tank systems are: methane, ethane, propane, butane, ethylene, propylene, butadiene (this range includes Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas (LPG), ammonia, nitrogen, oxygen and argon. NOTE - Properties of the gases are given in Annex A EN 14620-1:2024. This document provides requirements and specifies measures to be taken following completion of major tank construction activities and before the tank is brought in to service. It provides requirements for full-height and partial height hydrostatic testing to check the structural integrity of tanks and the capacity of the foundations. Settlement monitoring of the foundations at this stage form the starting point of an annual settlement monitoring programme for the tank foundation. Recommendations are given for marker systems for such monitoring. Requirements for water quality of both fresh water and seawater used during hydrotest, are provided to avoid the risk of corrosion of tanks and appurtenances. Guidance and requirements for positive and negative pneumatic tests to further check tank structural integrity, leak tightness of welds and the function of pressure and vacuum relief valve systems are also given. Requirements specific to testing of double-wall and membrane type tanks is included. Rules and procedures for commissioning activities, including drying and purging with inert and product gas are provided, including required oxygen concentrations for various RLG's. The document also provides guidance for cool-down procedures and suggestions for temperature monitoring, including an informative Annex A. For major maintenance inspection or at the end of the life of the tank, decommissioning will be required. Guidance on safe decommissioning processes is provided. Suggested procedures for Global testing for membrane tanks are provided in informative Annex B This document is applicable to the design and manufacture of site built, vertical, cylindrical, flat-bottomed tank systems for the storage of refrigerated, liquefied gases with operating temperatures between 0 °C and -196°C.

ČSN P CEN/TS 16628 Energetická náročnost budov - Podrobná technická pravidla pro soubor norem ENB
Obsah
ČSN P CEN/TS 16628 (73 0332) This document describes the basic principles to be followed in the development and maintenance of standards intended to support the assessment of the overall energy performance of a building (EPB) using a holistic approach. This document supports the development and maintenance of a set of EPB standards that provides a systematic, clear, consistent and comprehensive methodology for the benefit of professionals and government entities. The main application is the assessment of the overall energy performance of a building in the context of building regulations, e.g. to specify EP requirements, EP rating and EP certificates. The principles cover general and common aspects on the required quality, accuracy, usability, consistency and interoperability of the EPB standards as a set and individually. For that purpose, this document provides guidance on the process, structure and layout of these EPB standards and accompanying publications, complementary to the CEN and ISO internal regulations. This document forms the basis for detailed technical rules given in CEN/TS 16629, in the overarching EPB standard, EN ISO 52000-1:2017, and in supporting documents.
