ČSN EN ISO 1833-20 This document specifies a method using dimethylacetamide to determine the mass percentage of elastane, after removal of non-fibrous matter, in textiles made of mixtures of: - certain elastane fibres with - cotton, viscose, cupro, modal, lyocell, polyamide, polyester or wool fibres. This method is not applicable when acrylic fibres are present. It is also possible to analyse mixtures containing certain elastane fibres by using the test methods described in ISO 1833-12 or ISO 1833-21.

ČSN EN ISO 1833-6 This document specifies a method, using a mixture of formic acid and zinc chloride, to determine the mass percentage of viscose, certain types of cupro, modal or lyocell, after removal of nonfibrous matter, in textiles made of mixtures of - viscose, certain types of cupro, modal or lyocell, with - cotton. This document has been initially specifically established for mixtures of viscose, certain types of cupro, modal or lyocell with cotton, it is also applicable to mixtures with polypropylene, elastolefin and melamine. IMPORTANT - If a cupro or modal or lyocell fibre is found to be present, a preliminary test is carried out to see whether it is soluble in the reagent. The method is not applicable to mixtures in which the cotton has suffered extensive chemical degradation. It is not applicable when the viscose, cupro, modal or lyocell fibre is rendered incompletely soluble by the presence of certain permanent finishes or reactive dyes that cannot be removed completely.

ČSN EN ISO 3175-1 Tato první část normy specifikuje metodu pro hodnocení textilních výrobků, které byly zkoušeny podle ISO 3175-2 až ISO 3175-4. Určuje vlastnosti plošných textilií a oděvů, které se mohou měnit při chemickém čištění nebo čištění za mokra a při konečné úpravě, a uvádí vhodné metody pro hodnocení změn podle existujících mezinárodních norem. Další vlastnosti, které jsou také důležité, avšak pro které neexistují mezinárodní normy s metodami pro hodnocení, jsou uvedeny v příloze A (normativní), včetně doporučení, jak postupovat při jejich hodnocení.

ČSN EN ISO 10320 This document specifies the information accompanying geosynthetics to enable the user on site to identify the goods as being identical to the goods ordered. The positive identification, e.g. of unwrapped or rolled-out geosynthetics, is an important aim of this document. The information specified does not replace a technical data sheet and cannot be used to verify the conformance of the product with the technical requirements.

ČSN ETSI EN 301 489-51 V2.1.1 The present document, together with ETSI EN 301 489-1 [1], covers the assessment of automotive, ground based vehicles and surveillance radar devices using 24,05 GHz to 24,25 GHz, 24,05 GHz to 24,5 GHz, 76 GHz to 77 GHz and 77 GHz to 81 GHz in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port and emissions from the enclosure port of radar equipment are not included in the present document. Such technical specifications are found in the relevant product standards for the effective use of the radio spectrum. The present document specifies the applicable test conditions, performance assessment and performance criteria for automotive and surveillance radar devices and associated ancillary equipment. Automotive and surveillance radar equipments are low power millimetre wave devices that are able to detect and characterize targets in their environment. The following use cases are included (but are not limited to): - automotive Advanced Driver Assistance Systems (ADAS) applications, such as Adaptive Cruise Control (ACC), Blind Spot Detection (BSD), parking aid, backup aid, autonomous braking and pre-crash systems (PCS); - surveillance radars for other kind of ground based vehicles, such as trains, trams, aircrafts while taxiing; - fixed infrastructure radars for traffic monitoring; - railway/road crossings obstacle detection radars; - helicopter obstacle detection radars. Examples of automotive and surveillance radar devices are given in the related harmonised standards. In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and ETSI EN 301 489-1 [1], the provisions of the present document take precedence. The environmental classification and the emission and immunity requirements used in the present document are as stated in ETSI EN 301 489-1 [1], except for any special conditions included in the present document.

ČSN EN ISO 8289-2 This document specifies a low-voltage test method for detecting and locating defects (pores, cracks or pop-offs) that occur in enamel coatings of corrugated and/or undulated profiles and that extend down to the metal base. The method is based on colour effects (optical method) and is applicable to the precise detection of defects and their exact position. It can be used for non-flat, more profiled shapes such as corrugated or undulated surfaces. NOTE: The low-voltage test is a non-destructive test for detecting defects extending down to the metal base and is, therefore, completely different in comparison to the high-voltage test in accordance with ISO 2746.

ČSN EN ISO 11177 This document specifies the requirements for product quality and product testing of enamelled valves and pressure pipe fittings for untreated and potable water supply. It does not apply to chemical service glass-enamel and apparatus enamel.
