ČSN EN IEC 61267 ed. 3 Tato norma platí pro zkušební postupy, které za účelem stanovení parametrů systémů nebo komponentů lékařského diagnostického rentgenového zařízení vyžadují přesně definované podmínky rentgenového záření. Zabývá se metodami vytváření podmínek rentgenového záření, které lze použít za zkušebních podmínek typických pro zkušební laboratoře nebo výrobní závody k určení charakteristik lékařských dia-gnostických rentgenových zařízení. Toto třetí české vydání ruší a nahrazuje druhé vydání ČSN z roku 2006. Představuje jeho technickou revizi a obsahuje několik významných technických změn, přepracování a doplnění informativních i normativních příloh, revizi podmínek rentgenového záření, doplnění nové metody pro ověřování podmínek rentgenového záření a změny definic termínů.

ČSN EN IEC 62083 ed. 3 This document, with the inclusion of type tests and site tests, applies to the design, manufacture, installation, and maintenance of the radiotherapy treatment planning system. This document applies to the communication of the radiotherapy treatment planning system with other devices - used in medical practice, - that imports data either through input by the operator or from other devices, - that outputs data to other devices, and - that is intended to be - for normal use, under the authority of appropriately qualified persons, by operators having the required skills and training, - used and maintained in accordance with the recommendations given in the instructions for use, and - used within the environmental conditions specified in the technical description. This document applies to any software application that is used for the development, evaluation, or approval of a treatment plan, whether stand-alone or part of another system.

ČSN EN ISO 5659 This document specifies a method of measuring smoke production from the exposed surface of specimens of materials or composites. It is applicable to specimens that have an essentially flat surface and do not exceed 25 mm in thickness when placed in a horizontal orientation and subjected to specified levels of thermal irradiance in a closed cabinet with or without the application of a pilot flame. This method of test is applicable to all plastics. It is intended that the values of optical density determined by this test be taken as specific to the specimen or assembly material in the form and thickness tested and are not to be considered inherent, fundamental properties. The test is intended primarily for use in research and development and fire safety engineering in buildings, trains, ships, etc. and not as a basis for ratings for building codes or other purposes. No basis is provided for predicting the density of smoke that can be generated by the materials upon exposure to heat and flame under other (actual) exposure conditions. This test procedure excludes the effect of irritants on the eye. It is emphasized that smoke production from a material varies according to the irradiance level to which the specimen is exposed. The results yielded from the method specified in this document are based on exposure to the specific irradiance levels of 25 kW/m2 and 50 kW/m2.

ČSN EN ISO 14019-1 This document specifies general principles and requirements for the validation/verification of declared sustainability information, including reporting on environmental, social, governance and other sustainability matters. This document is applicable to quantitative and qualitative information. NOTE - These principles and requirements complement the set of rules and procedures that are provided in validation/verification programmes. This document is also applicable as the basis for validation/verification activities that support other conformity assessment schemes. This document is applicable to validation/verification bodies operating in accordance with ISO/IEC 17029.

ČSN EN ISO 9809-4 This document specifies the minimum requirements for the materials, design, construction and workmanship, manufacturing processes, examinations and testing at time of manufacture for refillable, seamless, stainless steel gas cylinders with water capacities up to and including 150 l. It is applicable to cylinders for compressed, liquefied and dissolved gases with a maximum actual tensile strength, Rma, of less than 1 100 MPa. NOTE - If so desired, cylinders of water capacity between 150 l and 450 l can be manufactured to be in full conformance to this document.

ČSN EN IEC 62541-21 This part of IEC 62541 defines the life cycle of Devices and Composites and mechanisms to verify their authenticity, set up their security and maintain their configuration. The NodeIds of all Nodes described in this standard are only symbolic names. Annex A defines the NamespaceUri for all NodeIds and the actual NodeIds.

ČSN EN ISO 24016 This document specifies the terminology, classification and the methods that are used for the grading and description of single unmounted polished diamonds over 0,25 carat (ct). This document applies to natural, unmounted, polished diamonds. It is not to be used for fancy coloured diamonds, synthetic diamonds, treated diamonds (other than is allowed for in 7.4), nor for assembled stones.

ČSN EN ISO 3845 This document gives a method for determining the resistance to cracking of steel pipes in sour service. This test method employs a full-scale test specimen consisting of a short length of pipe (a 'full ring'), sealed at each end to contain the sour test environment within. The test method applies to any pipe; seamless, longitudinally welded (with or without filler), helical welded, and to girth welds between pipes. NOTE 1 - The specimen is usually a pipe but can also consist of flange neck or section of a bend, or other tubular component or a combination of the above. NOTE 2 - This test method can also be used for corrosion resistant alloys (CRAs). The method utilizes ovalization by mechanical loading to produce a circumferential stress, equal to the target hoop stress, at two diametrically opposite locations on the inside surface of the test specimen. The test specimen is then subjected to single sided exposure to the sour test environment. NOTE 3 - The test also allows measurement of hydrogen permeation rates.
