ČSN EN 15553+A1 Tento dokument popisuje metodu adsorpční chromatografie s fluorescenčním indikátorem pro stanovení skupin uhlovodíků. Je určena pro stanovení aromatických uhlovodíků v koncentračním rozsahu od 5 % (V/V) do 99 % (V/V), pro olefiny v koncentračním rozsahu od 0,3 % (V/V) do 55 % (V/V) a pro nasycené uhlovodíky pro koncentrace od 1 % (V/V) do 95 % (V/V) v ropných frakcích, které destilují při teplotách do 315 °C. Tato metoda se může použít pro koncentrace spadající i mimo tyto rozsahy, ale nebyla stanovena její preciznost. Jestliže se analyzují vzorky, které obsahují přidávané kyslíkaté složky, mohou být výsledky skupin uhlovodíků zaznamenány bez korekce na obsah kyslíkatých látek, nebo je-li obsah kyslíkatých látek znám, výsledky mohou být korigovány na celkové složení vzorku. Tato metoda zkoušení je použitelná pro celé destilační rozmezí výrobků. Byla získána související data, která ukazují, že nelze použít ustanovení o preciznosti pro ropné frakce s úzkými destilačními rozmezími v blízkosti teploty 315 °C. Takové vzorky neeluují správně a výsledky jsou chybné. Vzorky obsahující tmavě zbarvené složky, které ruší odečty chromatografických pásů, nemohou být analyzovány.

ČSN EN 18051 This document specifies a test method for the determination of the content of n-butyl phenyl ether (BPE, CAS: 1126-79-0, also known as butoxy-benzene) in gas oils, kerosene, diesel fuel and biodiesel blends. The method uses a two-column gas chromatograph with an FID-type of detector. The application range is 0,1 mg/l to 21,25 mg/l of BPE, with a limit of detection of 0,05 mg/l. The method is found to be applicable to determinations beyond this range or for specific other chemical markers that fall within the distillation temperature range of middle-distillates, but for that no precision has been determined.

ČSN EN 196-12 Tento dokument určuje dvě rovnocenné zkušební metody pro hodnocení chemické aktivity pucolánové nebo latentně hydraulické složky cementu nebo příměsi betonu stanovením hydratačního tepla (viz kapitola 5 a článek 8.3 Metoda A, Hydratační teplo) nebo obsahu vázané vody (viz kapitola 5 a článek 8.4 Metoda B, Obsah vázané vody) hydratovaných past složených ze složky cementu nebo příměsi betonu, hydroxidu vápenatého, uhličitanu vápenatého, síranu draselného a hydroxidu draselného, vytvrzených při teplotě 40 °C po dobu 72 hodin a 168 hodin (3 dnů a 7 dnů). Tyto dvě zkušební metody stanovují chemickou aktivitu zkušebních vzorků složek cementu nebo příměsí betonu, u nichž se uvažuje s použitím. Tyto dvě zkušební metody nerozlišují latentně hydraulickou a pucolánovou aktivitu. Zkušební metody se používají pro účely vhodnosti, pokud se složky cementu nebo příměsi betonu zkoušejí při jemnosti stanovené příslušnými výrobkovými normami. Pokud norma výrobku nebo specifikace v normě výrobku neexistuje, zkouší se složky při jemnosti odpovídající zamýšlenému použití. Zkušební metody se rovněž použijí pro zkoušení dalších nových složek, které mají latentně hydraulické nebo pucolánové vlastnosti, a které nejsou uvedeny v řadě norem EN 197. U takových nových složek však nebyla ověřena platnost základních korelací s vývojem pevnosti, a proto lze výsledky zkoušek použít pouze pro informativní a orientační účely. Dále se tyto zkušební metody použijí při výrobní kontrole složek cementu pro hodnocení jejich latentně hydraulické nebo pucolánové aktivity.
