ČSN EN 16834 This document defines a harmonized way to assess the braking performance by test of locomotives, passenger coaches, freight wagons and self-propelled passenger trains (EMU/DMU). The document sets out the standardized method for undertaking brake performance tests and the correction factors to be applied to the data obtained for all types of rolling stock. This document also defines the methods to assess the brake performance in terms of stopping distance, and from this the process to determine vehicle(s) deceleration and braked weight. It then deals with conversion of the braked weight to the braked weight percentage of a vehicle or train for operating purposes. It also sets out additional factors when determining the braked weight percentage of a train calculated from specified braked weight, depending on the formation of the train. In Annex D there is a method for determining brake performance of freight wagons fitted with P10 cast iron or LL-blocks using limited testing (force measurement).

ČSN EN 16603-33-11 This Standard defines the requirements for the use of explosives on all spacecraft and other space products including launch vehicles. It addresses the aspects of design, analysis, verification, manufacturing, operations and safety. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.

ČSN EN 16603-33-01 This Standard specifies the requirements applicable to the concept definition, design, analysis, development, production, test verification and inorbit operation of space mechanisms on spacecraft and payloads in order to meet the mission performance requirements. This version of the standard has not been produced with the objective to cover also the requirements for mechanisms on launchers. Applicability of the requirements contained in this current version of the standard to launcher mechanisms is a decision left to the individual launcher project. Requirements in this Standard are defined in terms of what shall be accomplished, rather than in terms of how to organise and perform the necessary work. This allows existing organizational structures and methods to be applied where they are effective, and for the structures and methods to evolve as necessary without rewriting the standards. Complementary non-ECSS handbooks and guidelines exist to support mechanism design. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

ČSN EN ISO 11138-7 This document provides guidance for the selection, use and interpretation of results from application of biological indicators when used in the development, validation and routine monitoring of sterilization processes. It does not consider those processes that rely solely on physical removal of microorganisms, e.g. filtration. It is not applicable to combination processes using, for example, washer-disinfectors or flushing and steaming of pipelines. It does not specify requirements for the selection and use of biological indicators intended to monitor vaporised hydrogen peroxide processes for isolator and room biodecontamination processes at atmospheric pressure. It is not applicable to liquid immersion sterilization processes.

ČSN ETSI EN 302 637-3 V1.3.1 The present document provides specification of the DEN basic service, which is in support of the RHW application. More specifically, the present document specifies the syntax and semantics of the "Decentralized Environmental Notification Message" (DENM) and the DENM protocol handling. The DEN basic service may be implemented in an vehicle ITS-S, a road side ITS-S, a personal ITS-S or a central ITS-S.

ČSN ISO 55002 This International Standard provides guidance for the application of an asset management system, in accordance with the requirements of ISO 55001. This International Standard can be applied to all types of assets and by all types and sizes of organizations. NOTE 1: This International Standard is intended to be used for managing physical assets in particular, but it can also be applied to other asset types. NOTE 2: This International Standard does not provide financial, accounting or technical guidance for managing specific asset types. NOTE 3: For the purposes of ISO 55000, ISO 55001 and this International Standard, the term "asset management system" is used to refer to a management system for asset management.

ČSN EN 12896-8 The main objective of the present standard is to present the Reference Data Model for Public Transport, based on: - the Reference Data Model, EN 12896, known as Transmodel V5.1; - EN 28701:2012, Intelligent transport systems - Public transport - Identification of Fixed Objects in Public Transport (IFOPT), although note that this particular standard has been withdrawn as it is now included within Parts 1 and 2 of this standard (EN 12896-1:2016 and EN 12896-2:2016) following their successful publication; incorporating the requirements of: - EN 15531-1 to -3 and CEN/TS 15531-4 and -5: Public transport - Service interface for real-time information relating to public transport operations (SIRI); - CEN/TS 16614-1 and -2: Network and Timetable Exchange (NeTEx), in particular the specific needs for long distance train operation. Particular attention is drawn to the data model structure and methodology: - the data model is described in a modular form in order to facilitate the understanding and the use of the model; - the data model is entirely described in UML. The following functional domains are considered: - Network Description: routes, lines, journey patterns, timing patterns, service patterns, scheduled stop points and stop places; - Timing Information and Vehicle Scheduling (runtimes, vehicle journeys, day type-related vehicle schedules); - Passenger Information (planned and real-time); - Fare Management (fare structure, sales, validation, control); - Operations Monitoring and Control: operating day-related data, vehicle follow-up, control actions; - Driver Management: - Driver Scheduling (day-type related driver schedules), - Rostering (ordering of driver duties into sequences according to some chosen methods), - Driving Personnel Disposition (assignment of logical drivers to physical drivers and recording of driver performance); - Management Information and Statistics (including data dedicated to service performance indicators). The data modules dedicated to cover most functions of the above domains will be specified. Several concepts are shared by the different functional domains. This data domain is called "Common Concepts".
