ČSN ISO 21219-21 Tato norma definuje metodu používání geografického odkazování na polohu (GLR) pro použití v různých aplikacích TPEG. Metoda GLR popsaná v tomto dokumentu umožňuje popsat objekt zájmu pomocí geometrických geograficky lokalizovaných objektů typu bod, kruh, výseč kruhu, plný polygon či polygon s vnitřním otvorem. Metoda je zamýšlena zejména pro aplikace TPEG, které poskytují informace pro geografické oblasti (počasí, bezpečnostní výstrahy apod.). Metoda odkazování na polohu GLR má být doplňkem k metodám odkazování na polohu na základě map, kde se klade důraz na odkazování na pozemní prvky jako jsou silnice a dálnice.

ČSN P ISO/TS 22741-10 Proměnné dopravní značení (VMS) se instaluje v místech, kde správci za účelem řízení a informování v dopravě shledávají potřebu předávat informace cestujícím, např. před křižovatkami či nehodovými místy, aby upozornili cestující na dopravní či jiné komplikace ve směru jízdy, a ti tak mohli včas reagovat změnou trasy či přizpůsobit rychlost jízdy aktuálním podmínkám. Toto opatření umožňuje dispečerům dopravy zlepšit efektivitu řízení, zvýšit bezpečnost a zajistit vyšší kvalitu dopravního provozu. Pro řízení provozu využitím VMS a zobrazovaných zpráv je nutná výměna informací v reálném čase mezi systémy řízení a VMS. Tento dokument uvádí základní potřeby uživatelů pro ovládání VMS s činnou plochou tvořenou LED diodami.

ČSN EN ISO 14903 This document specifies the qualification procedure for type approval of the tightness of hermetically sealed and closed components, joints and parts used in refrigerating systems and heat pumps as described in relevant parts of the ISO 5149 series, including metal flexible piping. It specifies the level of tightness of the component as a whole and its assembly as specified by the manufacturer. It specifies additional requirements for mechanical joints that can be recognized as hermetically sealed joints. This document is applicable to joints of maximum DN 50 and components of internal volume of maximum 5 l and maximum weight of 50 kg. It is applicable to the hermetically sealed and closed components, joints and parts (e.g. fittings, bursting discs, flanged or fitted assemblies) used in the refrigerating installations, including those with seals, whatever their material and design are. This document does not apply to the tightness of flexible piping made from non-metallic material. This is covered in ISO 13971. Components tested before the date of publication of this document and found to comply with ISO 14903:2017 are considered to comply with this document.

ČSN EN ISO 4064-4 This document applies to water meters used to meter the volume of cold potable water and hot water flowing through a fully charged, closed conduit. These water meters incorporate devices which indicate the integrated volume. This document specifies technical characteristics and pressure loss requirements for meters for cold potable water and hot water. It applies to water meters which can withstand: a) a maximum admissible pressure (MAP) equal to at least 1 MPa1) [0,6 MPa for meters for use with pipenominal diameters (DNs) >= 500 mm]; b) a maximum admissible temperature (MAT) for cold potable water meters of 30 °C; c) a MAT for hot water meters of up to 180 °C, depending on class. In addition to meters based on mechanical principles, this document also applies to water meters based on electrical or electronic principles, and to water meters based on mechanical principles incorporating electronic devices, used to meter the volume flow of hot water and cold potable water. It also applies to electronic ancillary devices. As a rule ancillary devices are optional. However, national or international regulations may make some ancillary devices mandatory in relation to the utilization of the water meter.

ČSN EN IEC 63404 This document defines radiocommunication related requirements for equipment intended to integrate a radiocommunication device. It includes the initial integration and update of a the radiocommunication device, having a carrier frequency greater than 380 MHz, into new or updated host equipment with the classification of integration categories; the EMC immunity verification using a capability profile approach and the verification of the unwanted emission level of the radio transceiver. This document also provides typical radiocommunication device integration use cases (see Annex A). The object of this document is to define the required evaluation when incorporating a radiocommunication device into a new or updated host equipment. This document is intended to be referred by the product standard of the host equipment for providing additional characteristics, performance, and evaluation regarding the integration and update of a radiocommunication device (see Annex C). It can also be used by the manufacturer of the host equipment when no applicable product standard exists. In addition, this document provides guidance on considerations to be addressed in product standards including safety and security matter.
