ČSN EN 4259 This document defines the general terms to be used in the standards of metallic materials for aerospace applications. It is intended only to give terms which are truly general and where definition, in this context, is required. The definitions of more specific terms are to be found in the technical specifications, test methods, etc. which are referenced in the material standard concerned.

ČSN EN IEC 60587 ed. 2 Tato norma popisuje dvě zkušební metody hodnocení elektroizolačních materiálů pro použití ve ztížených podmínkách prostředí při průmyslových kmitočtech (od 45 Hz do 65 Hz) pomocí vyhodnocení jejich odolnosti proti vytváření vodivých cest (lokálními povrchovými výboji) a erozi (svodovými proudy nebo výboji) při použití kapalné znečišťující látky a šikmo uložené vzorky. Jedna z metod používá konstantní napětí, druhá používá napětí stupňovité.

ČSN EN IEC 63033-3 ed. 2 (36 8609) This document specifies measurement methods for the surround view system specified in IEC 63033-1.

Obsah

ČSN EN IEC 63033-4 (36 8609) This document specifies which composite images generated from the multiple cameras of the surround view system specified in IEC 63033-1 comprise the FOV, and which display requirements specified in UN Regulation No. 46 apply.

ČSN EN ISO/IEC 24760-1 Systémy zpracování dat obvykle shromažďují řadu informací o svých uživatelích, ať už jde o osobu, část za-řízení nebo část softwaru, které jsou k nim připojeny, a rozhodují se na základě získaných informací. Pro řešení potřeby účinně a efektivně implementovat systémy, které činí rozhodnutí založená na identitě, specifikuje soubor norem ISO/IEC 24760 rámec pro vydávání, správu a používání dat, která slouží k charak-terizaci jednotlivců, organizací nebo komponent informačních technologií, které fungují v zastoupení jednotlivců nebo organizací. Pro mnoho organizací je řádná správa informací o identitě zásadní pro zachování bezpečnosti organizačních procesů. Pro jednotlivce je řádná správa identity důležitá pro ochranu soukromí. Soubor ISO/IEC 24760 specifikuje základní pojmy a provozní struktury správy a řízení identit s cílem realizovat správu informačních systémů tak, aby informační systémy mohly plnit obchodní, smluvní, regulatorní a právní závazky. Tato norma definuje termíny pro správu a řízení identit a specifikuje základní pojmy identity a správy a řízení identity a jejich vzájemné vztahy. Normu lze použít pro jakýkoli informační systém, který zpracovává informace o identitě.

ČSN EN ISO 13503-3 This document covers the physical properties, potential contaminants and test procedures for heavy brine fluids manufactured for use in oil and gas well drilling, completion, and workover fluids. This document supplements API RP 13J, 5th edition (2014), the requirements of which are applicable with the exceptions specified in this document. This document provides more suitable method descriptions for determining the formate brines pH, carbonate/bicarbonate concentrations and crystallization temperature at ambient pressure compared to the methods provided by API RP 13J, 5th edition (2014). This document is intended for the use of manufacturers, service companies and end-users of heavy brines.

ČSN EN ISO 11358-1 This document specifies general conditions for the analysis of polymers using thermogravimetric techniques. It is applicable to liquids or solids. Solid materials can be in the form of pellets, granules or powders. Fabricated shapes reduced to appropriate specimen size can also be analysed by this method. This document establishes methods for the investigation of physical effects and chemical reactions that are associated with changes of mass. This document can be used to determine the temperature(s) and rate(s) of decomposition of polymers, and to measure at the same time the amounts of volatile matter, additives and/or fillers they contain. This document is applicable to measurements in dynamic mode (mass change versus temperature or time under programmed temperature conditions) or isothermal mode (mass change versus time at constant temperature). This document is applicable to measurements at different testing atmospheres, such as separation of decomposition in an inert atmosphere from oxidative degradation.

ČSN EN ISO 8655-2 This document specifies - metrological requirements, - maximum permissible errors, - requirements for marking and - information to be provided for users, for air-displacement (type A) and positive displacement (type D) single-channel and multi-channel pipettes, complete with their selected tip(s) and any other essential, consumable parts, designed to deliver the selected volume (Ex).

ČSN EN ISO 8655-5 This document specifies - metrological requirements, - maximum permissible errors, - requirements for marking and - information to be provided for users, for dispensers. It is applicable to dispensers with nominal volumes from 1 µl up to 200 ml, designed to deliver their volume (Ex).

ČSN EN ISO 8655-1 This document specifies general requirements for piston-operated volumetric apparatus (POVA). It is applicable to pipettes, burettes, dilutors, dispensers and manually operated precision laboratory syringes. It furthermore defines terms for the use of piston-operated volumetric apparatus and gives user recommendations. This document does not apply to medical products intended for use on humans, e.g. for medical syringes.

ČSN EN 17468-1 The document establishes an agreed method for evaluation of pull through resistance (tension/compression for fasteners through the sheets), shear resistance, bending strength and bending modulus of elasticity and suggests an approved safety concept of fibre-cement flat sheets for internal and external wall and ceiling finishes based on the experiences obtained over the last number of years in different countries. The results are only applicable to the fibre-cement product and not to the complete fixing assembly. The results are also applicable for coated or uncoated sheets manufactured at the same production facility as the tested sheets provided that the sheets are of the same type, have at least the same declared class according to EN 12467:2012+A2:2018, Table 6 and at least the same nominal thickness. The test method can be applied to textured or non-textured fibre-cement flat sheets. The results of non-textured sheets are only applicable for textured sheets if the nominal minimum thickness of the textured sheet is at least the nominal thickness of the non-textured sheet. The same type of fixing head or washer assembly where applicable if the diameter of the fixing head or washer is 0 mm to 2 mm larger than in the test. The Shore A hardness of the sealing washer, where applicable, is ± 5 that of the washer used in the test, given that the washer thickness is at least as thick, the washer material at least as strong and the shape (dome or flat) of the washer equal to what has been tested.
