ČSN EN 13381-10 (73 0858) This document specifies a fire test method and an assessment procedure for determining the contribution of fire protection systems to the fire resistance performance of circular and rectangular steel bars used as tension members. This document applies to fire protection materials that have already been tested and assessed in accordance with EN 13381-4 or EN 13381-8. For other section shapes such as angles, channels and flats, reference can be made to EN 13381-4 and EN 13381-8. This document does not include steel or any other cold formed bar used as reinforcement in concrete construction. For other solid bar geometries such as oval or triangular cross section, these are subject to a separate test package in accordance with the principles of Clause 5 of this document. Fire protection performance is determined by testing of unloaded tension members, although additional loaded test evidence can be required for certain product types subject to certain conditions specified in the document. The method is applicable to all fire protection systems used for the protection of solid bar up to a maximum diameter of 130 mm and includes sprayed fire protection, reactive coatings, cladding protection systems and multi-layer or composite fire protection materials. In the case of rectangular bar, the maximum side length is limited to 130 mm with a maximum aspect ratio of 2:1 against the shorter side length. For dimensions greater than 130 mm it is appropriate to use rectangular or circular hollow sections tested and assessed in accordance with EN 13381-4 and EN 13381-8 provided they have been tested in the same orientation. The evaluation is designed to cover a range of thicknesses of the applied fire protection material, a range of steel bar dimensions, a range of specified temperatures and a range of valid fire protection periods. The test method is applicable to fire protection systems which are intimately in contact with the bar, or which include an airspace between the bar and the protection system as given in EN 13381-4. This document also provides the assessment procedure, which prescribes the analysis of the test data and gives guidance on the procedures to undertake interpolation. This document caters for testing in both vertical and horizontal orientations. Results from horizontally orientated bar can be applied to any orientation, whilst results from vertically orientated bar are only used for horizontal bars when the data has been corrected in accordance with Annex C. This document gives the fire test procedures, carried out to provide data on the thermal characteristics of the fire protection system, when exposed to the standard temperature/time curve specified in EN 1363-1. The assessment procedure is used to establish: a) on the basis of data derived from testing steel bar, any practical constraints on the use of the fire protection system under fire test conditions (the physical performance); b) on the basis of the temperature data derived from testing steel bar the thermal properties of the fire protection system (the thermal performance). The limits of applicability of the results of the assessment arising from the fire test are defined together with application of the results to different steel types and sizes over the range of thicknesses of the applied fire protection system tested.

ČSN EN ISO 20705 This document specifies common methods for the quantitative microscopical analysis of various mixtures of fibres. The methods described are based on the use of a light microscope (LM) or a scanning electronic microscope (SEM), on the measurements of the fibre apparent diameter (preparation of longitudinal views) or on the measurements of fibre section area (preparation of cross views), depending on the section shape of the fibres. NOTE 1 - When the section shape is circular or almost circular, the longitudinal views are appropriate. For the other section shapes, the cross views are adequate and Annex A lists conventional density of fibres to be used for the calculation of the mass percentage of the components. Pictures of section shapes of fibres can be found in ISO/TR 11827. NOTE 2 - Annex B presents statistical data on fibre diameter measurements (longitudinal view) and on fibre area measurements (cross view). The given procedures apply to fibres in any textile form when mixtures of fibres cannot be separated by manual methods or by chemical methods. Examples of mixtures of fibres are cashmere and wool, cotton and flax, flax and hemp.

ČSN P CEN/TS 13149-7 This document specifies the general rules for an on-board data communication system between the different systems that may be used within public transport vehicles, based on the Internet Protocol (IPv4, [3] and IPv6, [4]). This includes operational support systems, passenger information systems, fare collection systems, etc. This document describes: - the requirements for an on board IP network; - the overview architecture and components for an IP based on-board network; - the modular structure of the network architecture; - the Service Oriented Architecture (SOA) approach, and approach to defining services. Systems directly related to the safe operation of the vehicle (including propulsion management, brake systems, door opening systems) are excluded from the scope of this document and are dealt with in other standardization bodies. However, the architecture described in this document may be used for support services such as safety information messages. Interfaces to safety-critical systems should be provided through dedicated gateways with appropriate security provisions; for the purposes of this document, these are regarded as simply external information sources. This document is designed primarily for vehicles with a fixed primary structure, where networks can be installed on a permanent basis and the system configuration task consists largely of the integration, adjustment or removal of the functional end systems that produce and/or consume data. Public transport vehicles consisting of units linked temporarily for operational purposes (specifically, trains in which individual engines, cars or consists are routinely connected and disconnected) require additional mechanisms to enable the communications network itself to reconfigure. Such mechanisms are provided through other standards, notably the IEC 61375 series [5].

ČSN EN ISO 11665-3 This document describes spot measurement methods for determining the activity concentration of short-lived radon-222 decay products in the air and for calculating the potential alpha energy concentration. This document gives indications for performing a spot measurement of the potential alpha energy concentration, after sampling at a given place for several minutes, and the conditions of use for the measuring devices. The measurement method described is applicable for a rapid assessment of the potential alpha energy concentration. The result obtained cannot be extrapolated to an annual estimate potential alpha energy concentration of short-lived radon-222 decay products. Thus, this type of measurement is not applicable for the assessment of annual exposure or for determining whether or not to mitigate citizen exposures to radon or radon decay products. This measurement method is applicable to air samples with potential alpha energy concentration greater than 5 nJ/m3.
