ČSN ISO/IEC 19989-2 ISO/IEC 19989-2:2020 stanoví kritéria a metodiku, které jsou užitečné při hodnocení bezpečnosti biometrických systémů. Biometrické produkty a systémy sdílejí mnoho vlastností jiných produktů a systémů IT, které u kterých se k hodnocení bezpečnosti z pohledu normalizace využívá soubor norem ISO/IEC 15408 a norma ISO/IEC 18045. Biometrické systémy však ztělesňují určité funkce, které vyžadují specializovaná hodnoticí kritéria a metodiku, která není řešena souborem ISO/IEC 15408 a ISO/IEC 18045. Tyto se týkají především hodnocení biometrického rozpoznávání a detekce prezentačních útoků. To jsou funkce, kterým se věnuje právě soubor ISO/IEC 19989. Soubor ISO/IEC 19989 představuje most mezi principy hodnocení biometrických produktů a systémů defino-vaných v ISO/IEC 19792 a kritérii a metodickými požadavky pro hodnocení bezpečnosti na základě souboru ISO/IEC 15408. Soubor ISO/IEC 19989 doplňuje soubory ISO/IEC 15408 a ISO/IEC 18045 tím, že poskytuje rozšířené bezpečnostní funkční komponenty spolu s doplňkovými činnostmi souvisejícími s těmito požadavky. Rozšíření požadavků a doplňkových činností nalezených v souborech ISO/IEC 15408 a ISO/IEC 18045 souvisí s hodnocením biometrického rozpoznávání a detekce prezentačních útoků, které se týkají zejména biometrických systémů. Tato norma obsahuje podrobného popisu výkonnosti biometrického rozpoznávání, čímž cílí na různé politiky zamýšleného použití biometrického systému a jejich vlivu na celkovou výkonnost systému. Na začátku normy je rozebrán obecný přehled hodnocení výkonnosti biometrických systémů. Stěžejním jádrem je popis chybových měr biometrického rozpoznávání, tj. metrik pro biometrickou verifikaci a identifikaci a stanovení maximálních hodnot těchto chybových měr. Neméně důležitou částí je popis plánování hodnocení, sestávající z odhadu velikosti testu, přípravy dokumentace testu, sběru dat, provedení testu, analýzy výsledků a kontroly. Následuje popis specifických požadavků na komponenty bezpečnostní záruky, hodnocení testů vývojářů opakováním testovací podmnožiny a provádění nezávislých testů. V přílohách jsou potom k nalezení příklady výpočtu potenciálu útoku pro činnosti AVA, příklady činností ATE a příklad dokumentu o testování výkonnosti vývojáře a jeho strategie hodnocení.

ČSN EN ISO 22766 This document specifies test methods for the determination of the degree of disintegration of plastic materials exposed to marine habitats under real field conditions. The marine areas under investigation are the sandy sublittoral and the sandy eulittoral zone where plastic materials can either be placed intentionally (e.g. biodegradable fishing nets) or end up as litter due to irresponsible human behaviour. This depends on their physical characteristics, form and size of the materials, and on water currents and tidal movements. This document specifies the general requirements of the apparatus, and the procedures for using the test methods described. The determination of the level of disintegration of plastic materials exposed to pelagic zones such as the sea surface or the water column above the seafloor are not within the scope of this document. This document is not suitable for the assessment of disintegration caused by heat or light exposure. The described field test is a disintegration test and not a biodegradation test. Therefore, it cannot be used for demonstrating biodegradation or for making unqualified claims such as "biodegradable in marine environment" and similar.

ČSN EN ISO 23977-1 This document specifies a laboratory test method for determining the degree and rate of the aerobic biodegradation level of plastic materials. Biodegradation is determined by measuring the CO2 evolved from plastic materials when exposed to seawater sampled from coastal areas under laboratory conditions. The conditions described in this document might not always correspond to the optimum conditions for the maximum degree of biodegradation, however this test method is designed to give an indication of the potential biodegradability of plastic materials. NOTE - This document addresses plastic materials but can also be used for other materials.

ČSN EN ISO 11916-3 This document specifies the measurement of explosives and related nitrocompounds (as given in Table 1) in soil and soil materials. This document is intended for the trace analysis of explosives and related compounds by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Generally, LC-MS/MS measurement shows the lower LOQ (limit of quantification) for each compound in Table 1 than using high-performance liquid chromatography (HPLC) with UV-detection (see Annex B and Annex C). Under the conditions specified in this document, concentrations as low as 0,005 mg/kg to 0,014 mg/kg-dry matter can be determined, depending on the substance. Similar compounds, in particular various nitroaromatics, by-products and degradation products of explosive compounds can be analysed using this method provided that the applicability is checked on a case-by-case basis.

ČSN EN ISO 16256 This document describes a method for testing the susceptibility to antifungal agents of yeasts, including Candida spp. and Cryptococcus neoformans, that cause infections. The reference method described here has not been used in studies of the yeast forms of dimorphic fungi, such as Blastomyces dermatitidis and/or Histoplasma capsulatum variety capsulatum. Moreover, testing filamentous fungi (moulds) introduces several additional problems in standardization not addressed by the current procedure. Those methods are beyond the scope of this document. This document describes the broth micro-dilution reference method, which can be implemented by either of two pathways. One pathway involves visual determination of MICs (CLSI method)[1][5]; the second pathway involves spectrophotometric determination of MICs (EUCAST method)[2][10]. The MIC reflects the activity of the drug under the described test conditions and can be interpreted for clinical management purposes by taking into account other factors, such as drug pharmacology or antifungal resistance mechanisms. In addition, MIC distributions can be used to define wild type or non-wild type fungal populations. Clinical interpretation of the MIC value is beyond the scope of this document; interpretive category breakpoints specific to the CLSI- and EUCAST-derived methods can be found by consulting the latest interpretive tables provided by the organizations[5][15]. Routine susceptibility testing methods or diagnostic test devices can be compared with this reference method in order to ensure comparable and reliable results for validation or registration purposes.
