ČSN EN 12082-1 This document is a part of a package of standards: EN 12080, EN 12081, EN 12082-1 and EN 12082-2. This document specifies the principles and methods for a rig performance test of the system of axlebox rolling bearing(s), housing, seal(s) and grease, required for reliable operation of trains on European networks. The necessary type and extent of testing are specified by the deployment procedure specified in EN 12082-2, with respect to design requirements on the axlebox and its components. This document covers a rig performance test, principles for a field test and a possible example for a water tightness test. Test parameters and minimum performance requirements for vehicles in operation on main lines are specified. Different test parameters and performance requirements may be selected for vehicles in operation on other networks (e.g. urban rail). This document is historically developed for outboard applications with rotating inner rings, but can be used for vehicles with inboard bearing arrangements with rotating inner rings. It gives some possible examples where a sequenced rig performance test addresses the broad range of different service conditions within a specific application or vehicle platform.

ČSN EN 1646-1 This document specifies requirements intended to ensure the safety and health of persons when they use motor caravans for temporary or seasonal habitation. It also specifies the corresponding test methods. Specific requirements of this document apply to motor caravans where the overall length multiplied by the overall width does not exceed 13,5 m2 plan area. Requirements applicable to road safety are not included in the scope of this document. This document is applicable exclusively to motor caravans as defined in EN 13878.

ČSN EN 9276 The purpose of this document is to: - identify and describe, in a structured way, the principles of the integrated logistic support (ILS) activities and tasks for the main types of stakeholders in the system life cycle, from the expression of need to disposal; - place the activities, tasks and ILS deliverables within the programme execution; - identify the main selection and sizing of activities and tasks criteria according to the nature and the requirements of the programme; - control the relations with the other aspects of programme management. This document covers the following subjects: - management of ILS (definition, implementation and running of the processes); - expression of the support requirements; - elaboration of the contracts (e.g. for development, maintenance, supply); - implementation of the tasks and processes. This document is also related to the following subjects: - relations with costs and lead times control, configuration management, performance and RAMS management, quality assurance, documentation management; - regulations (e.g. information system security, export controls, safety at work); - human and organizational factors (HOF); - environment (e.g. RoHS, REACh); - information systems (IS) and the links between them; - logistics information systems (LIS); - in-service support (ISS) activities; - configuration management of ILS objects; - life cycle. The following stakeholders are concerned by ILS: - users in the broadest sense: operators, maintenance operators, administrators, dismantlers of the system, trainers; - the customer, who: - prepares technical and contractual specifications of need with which the system will comply; - sets up the funding of the programme; - oversees the realization and commissioning of the main system and of the support system; - facilitates the feedback. NOTE 1 At the highest level of the system, the customer can also be referred to as the "project owner". NOTE 2 The "main system" can also be referred to as the "system of interest". - the supplier(s) who deliver a system (main and support) to the customer, which meets the performance specifications on time and for the agreed cost, throughout the system life cycle; NOTE 3 At the highest level of the system, the supplier can also be referred to as the "industrial prime contractor". - the regulatory authorities that supervise and approve the support processes and equipment, as needed. The principles laid down in this document can be applied, after adaptation, to all the customer/supplier relations resulting from the breakdown of the main contract into sub-contracts.

ČSN EN 4700-002 This document specifies the requirements for the ordering, manufacture, testing, inspection and delivery of steel and heat-resisting alloy bars and sections. It is presupposed to be applied when referred to and in conjunction with the EN material standard unless otherwise specified on the drawing, order or inspection schedule.

ČSN EN IEC 60079-18 ed. 4 This part of IEC 60079 gives the specific requirements for the construction, testing and marking of electrical Ex Equipment, parts of electrical Ex Equipment and Ex Components with the Type of Protection encapsulation "m" (hereinafter referred to as "m" Equipment) intended for use in explosive gas atmospheres or explosive dust atmospheres. For Levels of Protection "mb" and "mc", this document applies where the rated voltage does not exceed 11 kV ACRMS or DC. For Level of Protection "ma", this document applies where the rated voltage does not exceed 1 kV ACRMS or DC. This document does not take account of any hazard due to an emission of flammable or toxic gas from the dust. This document supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this document conflicts with a requirement of IEC 60079-0, the requirement of this document takes precedence.

ČSN EN IEC 62683-2-2 This part of IEC 62683 2 specifies the building information modelling (BIM) with the physical characteristics and technical services of low-voltage switchgear and controlgear assemblies to be used mainly for the construction phase of the building and for delivering data for operation. This document covers all types of assemblies covered by the IEC 61439 series which can be installed in a building. Busbar trunking systems defined by IEC 61439 6 are under consideration for a next edition. These BIM object models, registered in IEC CDD, are intended to supply the process defined by ISO 16739 series. This document does not cover: - the built-in components included within the assembly such as switchgear and controlgear, - safety related control system of machinery, - the detailed electrical and mechanical configuration of the assembly - logistic information.

ČSN EN 50411-3-1 Norma obsahuje rozměrové, optické, mechanické a environmentální požadavky na krabice pro 288 vláknových spojů instalované na zeď nebo sloup, aby byly zařazeny jako produkt podle evropské normy. Typická konfigurace spočívá ve spojování příchozích vláken s volitelnými děliči, které jsou na druhé straně připojeny k odchozím vláknům. Norma specifikuje počet spojkových kazet a kapacitu spojů pro každou úroveň oddělení vláken. Maximální kapacita je 288 spojů. Pro uložení s vyšším počtem spojů lze použít EN 50411-4-1 (pouliční rozvodná skříň). Krabice pro spojování vláken a připojování pomocí propojovacích šňůr jsou popsány v EN 50411-3-4.

ČSN EN 18184 This document provides a specification for QR codes for mobile (instant) credit transfers (MCTs) whereby the payer uses a mobile device to initiate the payment transaction. The QR code is used to exchange data between the payer and the payee to enable the initiation of the (instant) credit transfer by the payer. This document is applicable to both cases where the QR code is presented by the payee or by the payer. This document ex-cludes the following from its scope: - The details of technical requirements and the supporting infrastructure to achieve interoperability amongst mobile (instant) credit transfer (MCT) service providers; - The detailed implementation specification of the payload included in the QR code.

ČSN EN 12680-1 This document specifies the requirements for the ultrasonic testing of steel castings (with ferritic structure) for general purposes and the methods for determining internal discontinuities by the pulse-echo technique. This document is applicable to the ultrasonic testing of steel castings which have usually received a grain refining heat treatment and which have wall thicknesses up to and including 600 mm. For greater wall thicknesses, special agreements are applicable with respect to test procedure and recording levels. This document does not apply to austenitic steels and joint welds. For highly stressed components EN 12680-2 is applicable.
