ČSN ISO/IEC 20926 ISO/IEC 20926:2009 specifikuje sadu definic, pravidel a kroků k aplikování metody IFPUG měření funkční velikosti. Tato mezinárodní norma je konformní se všemi povinnými ustanoveními normy ISO/IEC 14143-1:2007. Může být aplikována na všechny funkční domény a je plně převeditelná na předešlá vydání metody IFPUG posuzování velikosti. IFPUG analytici funkčních bodů identifikovali rychlosti dodávání (hodiny k dodání funkčního bodu) spojené s tvorbou aplikací v různých funkčních doménách kalibrovaných pro různé velikosti projektů a softwarových složitostí. Tato mezinárodní norma může být aplikována kýmkoliv po-žadujícím měření funkční velikosti. Osoby se zkušeností s touto metodou budou tuto mezinárodní normu považovat za užitečnou referenci.

ČSN EN 16618 This European Standard specifies a method for the determination of acrylamide in bakery ware such as bread, toasted bread, crisp bread, butter cookies, and biscuits, as well as potato products such as potato chips, potato crisps, and potato pan cake and roasted coffee, by liquid chromatography in combination with electrospray ionization and tandem mass spectrometry (LC-ESI-MS/MS). This method has been validated in an interlaboratory study via the analysis of both naturally contaminated and spiked samples, ranging from 14,3 µg/kg to 9 083 µg/kg. It was developed at the Swedish National Food Administration and validated in a study organized by the Directorate General Joint Research Centre (DG JRC), Swedish National Food Administration and the Nordic Committee on Food Analysis (NMKL), see [1] and [2]. The limit of quantification (LOQ) depends on the type of instrument used and on the actual performance of the instrument. The majority of the laboratories participating in the validation study were able to determine acrylamide in a butter cookie sample at a level of 14,3 µg/kg. Thus, the validation by interlaboratory study showed that LOQ can be expected to be in the range between below 15 µg/kg and 30 µg/kg.

ČSN EN 16187 This European Standard specifies a method for the determination of fumonisin B1 (FB1) and fumonisin B2 (FB2) in processed maize-containing foods for infants and young children by high performance liquid chromatography (HPLC) with immunoaffinity cleanup and fluorescence detection (FLD). This method has been validated in an interlaboratory study via the analysis of both naturally contaminated and spiked samples ranging from 112 µg/kg to 458 µg/kg for FB1+FB2, 89 µg/kg to 384 µg/kg for FB1 and 22 µg/kg to 74 µg/kg for FB2. For further information on the validation, see Clause 8 and Annex B.

ČSN EN ISO 6259-3 This part of ISO 6259 specifies a method of determining the tensile properties of polyolefin (polyethylene, cross-linked polyethylene, polypropylene, and polybutene) pipes, and the following properties: - the stress at yield; - the elongation at break. This part of ISO 6259 also gives the corresponding basic specifications in Annexes A to D for information purposes only.

ČSN P CEN/TS 16861 This Technical Specification specifies an analytical method for testing food grade, recycled polyethylene terephthalate (PET). This analytical method provides / is intended to be used as a quality control check. This test identifies and quantifies certain specified contaminants. Such contaminants are referred to as Marker Compounds. The analytical method is applicable for use on PET samples and products at all stages in the recycling process and will therefore be useful to recycling companies producing commercial, recycled PET for food contact materials and articles, and the manufacturers of such articles. This Technical Specification is without prejudice to any existing legislation. NOTE: Marker compounds are known to originate from two sources: - from the PET material itself (i.e. residual monomers, degradation products or reaction/breakdown products); - from food products that the PET has contacted during its "first use".

ČSN EN 14757 Tato norma stanovuje metodu pro odběr vzorků ryb v jezerech a vodních nádržích pomocí bentických mnohoočkových tenat a uvádí doporučení pro odběr vzorků pelagickými mnohoočkovými tenaty. Tato metoda popisuje odhady výskytu druhů ryb, kvantitativní relativní četnosti a biomasy ryb vyjádřené jako úlovek na jednotku úsilí (CPUE, Catch Per Unit Effort) a odhad velikostního složení rybí obsádky ve vodách mírného pásu. Odhady vycházející z normalizovaného odběru vzorků jsou dále porovnatelné v čase v rámci jednoho i více vodních útvarů.

ČSN EN ISO 12818 This International Standard specifies the tolerances for the bottles intended to be used for pharmaceutical products, cosmetic and perfumery products and chemical products. The following tolerances are concerned: - brimful capacity; - height; - diameter and width; - verticality. The following types of bottles are excluded from this International Standard: - "miniatures"; - small bottles for extracts, essences, etc.; - small jars (e.g. individual portions of jam).

ČSN P CEN/TS 16660 This Technical Specification specifies three laboratory tests to determine the reducing character and the reducing capacity of construction products, waste materials and the eluate resulting from exposure of these solids to a leachant. Reducing species released from the product are titrated to quantify the reducing capacity. For a specification of the materials with which experience has been acquired with the execution of the tests according to this Technical Specification see Annex A and [16]. NOTE: Materials with reducing properties can in practice under both oxidizing and anoxic (isolated) conditions show completely different leaching behaviour than obtained with the leaching tests specified in EN 16457. This may seriously hamper the interpretation of the leaching tests, if this condition is not taken into consideration.

ČSN EN ISO 8536-8 This part of ISO 8536 gives users information on sterilized infusion sets for single use with pressure infusion apparatus up to a maximum of 200 kPa (2 bar). In some countries, the national pharmacopoeia or other national regulations are legally binding and take precedence over this part of ISO 8536.

ČSN EN ISO 8536-10 This part of ISO 8536 applies to sterilized accessories for single use in fluid lines and pressure infusion equipment as specified in ISO 8536-8. This part of ISO 8536 includes the following: a) two-way stopcocks, three-way stopcocks, four-way stopcocks, and stopcocks manifold; NOTE: Designation of a stopcock depends on the number of connections. The number of possible functional positions can be expressed by addition of a complementary note, using a diagonal stroke and a numeral indicating the number of possible stopcock positions, e.g. 3/4-way stopcock for three-way stopcock with four possible positions. b) units with injection site or check valve; c) stoppers or adapters. In some countries, the national pharmacopoeia or other national regulations are legally binding and take precedence over this part of ISO 8536.
