ČSN P CEN/TS 16931-3-4 This documents specifies the mapping between the semantic model of an electronic invoice, included in EN 16931-1 and the ISO 9735 (UN/EDIFACT) syntax. For each element in the semantic model (including sub-elements or supplementary components such as Identification scheme identifiers) it is defined which element in the syntax is to be used to contain its information contents. Any mismatches between semantics, format, cardi-nality or structure are indicated.

ČSN EN IEC 62541-5 ed. 3 This part of IEC 62541 defines the Information Model of the OPC Unified Architecture. The Information Model describes standardized Nodes of a Server's AddressSpace. These Nodes are standardized types as well as standardized instances used for diagnostics or as entry points to server-specific Nodes. Thus, the Information Model defines the AddressSpace of an empty OPC UA Server. However, it is not expected that all Servers will provide all of these Nodes.

ČSN EN IEC 62541-14 This part of IEC 62541 defines the OPC Unified Architecture (OPC UA) PubSub communication model. It defines an OPC UA publish subscribe pattern which complements the client server pattern defined by the Services in IEC 62541-4. IEC TR 62541-1 gives an overview of the two models and their distinct uses. PubSub allows the distribution of data and events from an OPC UA information source to interested observers inside a device network as well as in IT and analytics cloud systems. This document consists of - a general introduction of the PubSub concepts, - a definition of the PubSub configuration parameters, - mapping of PubSub concepts and configuration parameters to messages and transport protocols, and - a PubSub configuration model. Not all OPC UA Applications will need to implement all defined message and transport protocol mappings. IEC 62541-7 defines the Profile that dictates which mappings need to be implemented in order to be compliant with a particular Profile.

ČSN EN IEC 60598-1 ed. 7 Tato část 1 IEC 60598 uvádí obecné požadavky na svítidla s elektrickými světelnými zdroji pro napájecí napětí nepřesahující 1 000 V. Požadavky a příslušné zkoušky této normy zahrnují: třídění, značení, mechanickou a elektrickou konstrukci. Zdůrazňuje se skutečnost, že tato část 1 zahrnuje všechna hlediska bezpečnosti (elektrické, tepelné a mechanické). Uvádění fotometrických údajů svítidel připravuje Mezinárodní komise pro osvětlování (CIE) a proto není začleněno do této části 1.

ČSN ETSI EN 301 549 V3.2.1 The present document specifies the functional accessibility requirements applicable to ICT products and services, together with a description of the test procedures and evaluation methodology for each accessibility requirement in a form that is suitable for use in public procurement within Europe. The present document is intended to be used with web based technologies, non-web technologies and hybrids that use both. It covers both software and hardware as well as services. It is intended for use by both providers and procurers, but it is expected that it will also be of use to many others as well. The relationship between the present document and the essential requirements of Directive 2016/2102 on the accessibility of the websites and mobile applications of public sector bodies [i.28] is given in Annex A. The present document contains the necessary functional requirements and provides a reference document such that if procedures are followed by different actors, the results of testing are similar and the interpretation of those results is clear. The test descriptions and evaluation methodology included in the present document are elaborated to a level of detail compliant with ISO/IEC 17007:2009 [i.14], so that conformance testing can give conclusive results.

ČSN EN IEC 61784-3-13 ed. 3 This part of IEC 61784 3 (all parts) specifies a safety communication layer (services and protocol) based on CPF 13 of IEC 61784 2 and IEC 61158 Type 13. It identifies the principles for functional safety communications defined in IEC 61784 3 that are relevant for this safety communication layer. This safety communication layer is intended for implementation in safety devices only. NOTE 1 - It does not cover electrical safety and intrinsic safety aspects. Electrical safety relates to hazards such as electrical shock. Intrinsic safety relates to hazards associated with potentially explosive atmospheres. This document defines mechanisms for the transmission of safety-relevant messages among participants within a distributed network using fieldbus technology in accordance with the requirements of IEC 61508 (all parts) for functional safety. These mechanisms may be used in various industrial applications such as process control, manufacturing automation and machinery. This document provides guidelines for both developers and assessors of compliant devices and systems. NOTE 2 - The resulting SIL claim of a system depends on the implementation of the selected functional safety communication profile within this system - implementation of a functional safety communication profile according to this document in a standard device is not sufficient to qualify it as a safety device.

ČSN EN 16603-10-04 This standard applies to all product types which exist or operate in space and defines the natural environment for all space regimes. It also defines general models and rules for determining the local induced environment. Project-specific or project-class-specific acceptance criteria, analysis methods or procedures are not defined. The natural space environment of a given item is that set of environmental conditions defined by the external physical world for the given mission (e.g. atmosphere, meteoroids and energetic particle radiation). The induced space environment is that set of environmental conditions created or modified by the presence or operation of the item and its mission (e.g. contamination, secondary radiations and spacecraft charging). The space environment also contains elements which are induced by the execution of other space activities (e.g. debris and contamination). This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

ČSN EN IEC 60839-11-33 This part of IEC 60839 defines the Web services interface for electronic access control systems. This includes listing electronic access control system components, their logical composition, monitoring their states and controlling them. It also includes a mapping of mandatory and optional requirements in accordance with IEC 60839-11-1:2013, as covered by Annex B. This document applies to physical security only. Physical security prevents unauthorized personnel, attackers or accidental intruders from physically accessing a building, room, etc. Web services usage and device management functionality are outside the scope of this document. Refer to IEC 60839-11-31:2016 for more information. This document does not in any way limit a manufacturer to add other protocols or extend the protocol defined here. For rules on how to accomplish this, refer to IEC 60839-11-31:2016.

ČSN ISO/IEC 8824-1 Tato norma poskytuje standardní způsob zápisu, který se nazývá Abstraktní syntaxe způsobu zápisu jedna (ASN.1), a který se používá pro definici typů dat, hodnot a omezení na typech dat. Tato norma: - definuje určitý počet jednoduchých typů s jejich tagy a specifikuje způsob zápisu pro odkazy na tyto typy a pro specifikaci hodnot těchto typů, - definuje mechanizmy pro konstruování nových typů z více základních typů a specifikuje způsob zápisu pro definování takových typů a přiřazování tagů těmto typům a pro specifikaci hodnot těchto typů, - definuje soubory znaků pro užití v ASN.1. Způsob zápisu ASN.1 lze aplikovat, kdykoli je to nutné pro definování abstraktní syntaxe informace.
