ČSN EN ISO 24014-1 This document gives guidelines for the development of multi-operator/multi-service interoperable public surface (including subways) transport fare management systems (IFMSs) on a national and international level. This document is applicable to bodies in public transport and related services which agree that their systems need to interoperate. This document defines a conceptual framework which is independent of organizational and physical implementation. Any reference within this document to organizational or physical implementation is purely informative. This document defines a reference functional architecture for IFMSs and establishes the requirements that are relevant for ensuring interoperability between several actors in the context of the use of electronic tickets. The IFMS includes all the functions involved in the fare management process, such as: - management of media, - management of applications, - management of products, - security management, and - certification, registration, and identification. This document defines the following main elements: - identification of the different sets of functions in relation to the overall IFMS and services and media from non-transport systems which interact with fare management systems; - a generic model of an IFMS describing the logical and functional architecture and the interfaces within the system, with other IFMSs and with services and media from non-transport systems; - use cases describing the interactions and data flows between the different sets of functions; - security requirements. This document does not define: - the technical aspects of the interface between the medium and the medium access device; - the data exchanges between the medium and the medium access device; NOTE - The data exchanges between the medium and the medium access device are proposed by other standardization committees. - the financial aspects of fare management systems (e.g. customer payments, method of payment, settlement, apportionment, reconciliation).

ČSN EN 15746-1 This document deals with the technical requirements to minimize the specific railway hazards of self-propelled road-rail machines - henceforward referred to as machines - and associated equipment, which can arise during the commissioning, operation and maintenance of the machines when carried out in accordance with the specification given by the manufacturer or his authorized representative. These risks are normally common regardless of the track gauge. However, additional requirements can apply for travelling and working on infrastructures with narrow gauge or broad gauge lines, railways utilizing other than adhesion between the rail and rail wheels and underground infrastructures. This document is also applicable for machines and associated equipment that in working configuration are partly supported on the ballast or the formation. Such machines are capable of independent self-propelled movement on the ground. This document does not apply to the following: - the requirements for quality of the work or performance of the machine; - the specific requirements established by the machine operator for the use of machines, which will be the subject of negotiation between the manufacturer and the Infrastructure Manager; - moving and working while not on rails; - separate machines temporarily mounted on machines and associated equipment; - demountable machines as defined in 3.2; - trailers as defined in 3.3, including road-rail trailers. Vehicles which are not track-guided themselves but have attachments that are track-guided are not road-rail machines. The requirements within this document are amended and added to by the requirements in EN 15746-4 for machines designed and intended to use urban rail. This document does not establish the additional requirements for the following: - operation subject to special rules, e.g. potentially explosive atmospheres; - hazards due to natural causes, e.g. earthquake, lightning, flooding; - working methods; - operation in severe working conditions requiring special measures, e.g. work in tunnels or in cuttings, extreme environmental conditions such as: freezing temperatures, high temperatures, corrosive environments, tropical environments, contaminating environments, strong magnetic fields; - hazards due to errors in software; - hazards occurring when used to handle suspended loads which may swing freely. For a road-rail machine it is assumed that an EU road permissible host vehicle will offer an accepted safety level for its designed basic functions before conversion. Unless explicitly stated otherwise in a particular clause this specific aspect is not dealt with in this European Standard. Other track construction and maintenance machines used on railway tracks are dealt with in other European Standards, see Annex F.

ČSN EN ISO 14907-2 This document describes tests which verify on-board unit (OBU) conformance of functions and data structures implementations, as defined in the implementation conformance statement (ICS) based on ISO 14906 for EFC applications. This document defines tests for assessing OBU conformance in terms of : - basic dedicated short-range communication (DSRC) L7 functionality, - EFC application functions, - EFC attributes (i.e. EFC application information), - the addressing procedures of EFC attributes and (hardware) components, - the EFC transaction model, which defines the common elements and steps of any EFC transaction, and - the behaviour of the interface so as to support interoperability on an EFC-DSRC application interface level. After the tests of isolated data items and functions (C.2 to C.4), an example is given for testing a complete EFC transaction (C.3). Although this document defines examples of test cases for DSRC and EFC functionality (see Annex C), it does not intend to specify a complete test suite for a certain implementation. To compose a test suite for a specific EFC implementation, the test cases can be modified and new test cases can be defined and added in order for the conformance test suite to be complete. It can be useful to consider the following when defining a complete test suite: - small range: "exhaustive testing" of critical interoperability/compatibility features, - large range: testing of boundaries and random values, and - composite types: testing of individual items in sequence or parallel. This document does not define tests which assess: - performance, - robustness, and - reliability of an implementation. NOTE 1 - ISO 14907-1 defines test procedures that are aimed at assessing performance, robustness and reliability of EFC equipment and systems. NOTE 2 - The ISO/IEC 10373 series defines test methods for proximity, vicinity, integrated circuit(s) cards and related devices that can be relevant for OBUs which support such cards. Annex D provides an informative overview of Japanese on-board equipment (OBE) conformance tests which are based on the ISO 14907 series, in order to illustrate how these can be applied in practice.

ČSN EN IEC 60079-10-1 ed. 3 Tato norma uvádí postupy pro zařazování nebezpečných prostorů, ve kterých může vznikat nebezpečí od hořlavých plynů nebo par a může být použita jako základ pro správný návrh, konstrukci, provoz a údržbu zařízení určených pro použití v nebezpečných prostorech. Norma je určena pro použití tam, kde může vznikat nebezpečí iniciace přítomných směsí hořlavých plynů a par se vzduchem, neplatí však pro: a) plynující doly s výskytem methanu; b) zpracování a výrobu výbušnin; c) katastrofické poruchy nebo výjimečná selhání, které jsou mimo rámec normálních stavů, se kterými se v této normě počítá (viz 3.7.3 a 4.5); d) místnosti pro lékařské účely; e) prostory v domácnostech. f) prostory, ve kterých může nebezpečí vznikat od hořlavých prachů nebo vláken, avšak pro hodnocení hybridních směsí mohou být tyto principy použity (viz také IEC 60079-10-2). POZNÁMKA - Další návod pro hybridní směsi je uveden v příloze I. Hořlavé mlhy se mohou tvořit nebo být přítomny ve stejnou dobu jako hořlavé páry. V těchto případech nemusí být vhodné striktní používání podrobností, uvedených v této normě. Kapaliny, které se nepovažují za nebezpečné ve smyslu této normy (v důsledku vysokého bodu vzplanutí), mohou při úniku pod tlakem vytvářet hořlavé mlhy. Pro tyto případy klasifikace a podrobnosti uvedené v této normě neplatí. Informace pro hořlavé mlhy jsou uvedeny v příloze G. Pro účely této normy je prostor třírozměrná oblast. Atmosférické podmínky zahrnují i odchylky nad a pod referenční úrovně 101,3 kPa (1 013 mbar) a 20 °C (293 K), pokud tyto odchylky mají zanedbatelný vliv na výbuchové vlastnosti hořlavých látek. V každé technologii, může být bez ohledu na její velikost velký počet iniciačních zdrojů jiných, než jsou zdroje iniciace vytvářené zařízením. V této souvislosti je nutno provést vhodná opatření pro zajištění bezpečnosti. Tato norma může být s odůvodněním použita i pro jiné iniciační zdroje, ale v některých aplikacích může být potřeba zvážit jiná bezpečnostní opatření. Například pro otevřené plameny se mohou používat větší odstupy, pokud se povoluje práce vytvářející teplo. Toto norma nepojednává o důsledcích při vznícení výbušné atmosféry, s výjimkou případů, kdy je zóna tak malá, že pokud dojde k iniciaci, bude to mít zanedbatelné následky (viz 3.3.8 a 4.4.2).
