ČSN EN 933-8+A1 Tato norma popisuje referenční metodu, používanou při zkoušce typu a v případě sporu, pro stanovení hodnoty ekvivalentu písku podílu 0/2 mm (pro 0/4 viz Příloha A) z drobného kameniva nebo ze směsi kameniva. V jiných případech, konkrétně při kontrole řízení výroby, smí být použity jiné metody s podmínkou, že jsou vhodné a podobné stanovené referenční metodě.

ČSN EN 14019 This Standard defines performance requirements of curtain walling under impact load. The mode of breakage of the glass has to be already assessed according to EN 12600. Its criteria are targeted to safety in use and integrity of curtain walling in the event of sudden impact forces on the curtain wall surfaces. Compliance with the performance requirement is determined by the laboratory test. It applies to those areas of curtain walling which face onto areas of human activity, either internally or externally and takes account of accidental impacts brought on by people going about their normal daily activities and impacts brought about by equipment and similar devices for maintenance, cleaning, repair and similar occasional activities. It does not set out to define performance requirements of impact under exceptional circumstances such as acts of vandalism, vehicular collision, firearm projectiles, etc. This standard will have no bearing whatsoever on any National Building / Health and Safety regulations which may exist and whose requirements have to apply separately and in parallel with these test performance requirements.

ČSN EN 14508 Tato norma stanovuje metody pro měření přepravní doby mezi koncovými body vnitrostátních a přeshraničních neprioritních jednotlivých zásilek sbíraných, zpracovávaných a dodávaných operátory poštovních služeb. Zabývá se metodami používajícími reprezentativní vzorek mezi koncovými body všech typů jednotlivých adresných listovních zásilek s definovanými úrovněmi služby přepravní doby nabízenými zákazníkovi. Tato norma je vhodná pro měření služeb jednotlivých neprioritních zásilek mezi koncovými body. Tato norma byla vypracována na základě EN 13850:2012 a je kompatibilní s jejími požadavky. Tato norma se týká měření tzv. "normálních" služeb poskytovaných soukromým osobám / domácnostem a menším podnikům, které podávají zásilky do poštovních schránek, u přepážky na poštách, mají sběrná místa ve svých kancelářích nebo podávají svoje zásilky přímo v třídicích střediscích operátorů poštovních služeb.

ČSN EN ISO 105-X12 This part of ISO 105 specifies a method for determining the resistance of the colour of textiles of all kinds, including textile floor coverings and other pile fabrics, to rubbing off and staining other materials. The method is applicable to textiles made from all kinds of fibres in the form of yarn or fabric, including textile floor coverings, whether dyed or printed. Two tests may be made, one with a dry rubbing cloth and one with a wet rubbing cloth.

ČSN EN ISO 105-D02 This part of ISO 105 specifies a method for determining the resistance of the colour of textiles of all kinds and in all forms, except loose fibre, to the combined action of rubbing and of organic solvents used in spot-cleaning, localized "spotting" carried out by hand.

ČSN EN ISO 105-X16 This part of ISO 105 specifies a method for determining the resistance of the colour of textiles to rubbing off and staining other materials where the singling out of areas smaller than possible to test with the apparatus described in ISO 105 X12 is required. Two tests may be made, one with a dry rubbing cloth and one with a wet rubbing cloth.

ČSN EN ISO 9863-1 This part of ISO 9863 specifies a method for the determination of the thickness of geosynthetics at specified pressures and specified load plate areas or under specified point loads. It defines the pressures or the load at which the thickness is determined. The test results are intended for identification purposes and for use in technical data sheets and/or as part of other test methods, e.g. tests of hydraulic properties. The method is applicable to all geosynthetics.

ČSN EN ISO 2157 This International Standard specifies the nominal diameters of the working parts of dental rotary instruments, for example burs, laboratory burs, grinding instruments, diamond instruments, mandrels and the corresponding designation. Excluded are the diameters of endodontic instruments and scaler tips.

ČSN EN ISO 19429 This International Standard provides a system for designating the location of an implant body within a jaw, and is intended for use with the scheme described in ISO 3950. It does not in itself indicate whether the device is visible within the oral cavity or the presence of transmucosal components or implant restorations. Since the system describes location but not restoration form, it is not necessary to use the quadrant designation numbers 5 to 8 which are employed when indicating a primary tooth. This information should be recorded by the responsible clinician in the patient's file and made available to the patient by the clinician(s) who provided the care.

ČSN EN 12503-4 This European Standard specifies a method of test for the determination of shock absorption characteristics of sports mats types 1 to 8 of EN 12503-1:2013, 9 to 11 of EN 12503-2:2016 and 12 of EN 12503-3:2001.

ČSN EN 16889 This This European Standard specifies hygiene requirements which establish prerequisites for production of hot beverages, such as coffee and coffee specialities, tea, cocoa and dairy beverages from hot beverage appliances for commercial and household use in conformity with the food hygiene regulations and for placing on the market. Appliances for self-service are within the scope of this standard. For this purpose, this standard specifies general hygienic requirements for the construction, material and operation of the appliances concerned. It contains, in particular, requirements for hygienic and professional operation, for cleaning, disinfection and descaling as well as requirements for a migration test. This European Standard applies to appliances before their entering on the market (new machines) and it also gives an informative Annex for appliances already in use (see Annex A). This European Standard does not deal with any requirements relevant to work safety. This European Standard deals neither with electrical safety nor with performance requirements. EN 60335 2 15 and EN 60335 2 75 have to be used for commercially used appliances. Methods for measuring the performance of electric household coffee makers are provided in EN 60661.
