ČSN EN 18003 This document specifies a high-performance liquid chromatography (HPLC) method for determining the 16-O-Methylcafestol content in green and roasted coffee. The method is suitable for a content of 40 mg/kg to 1 600 mg/kg of 16-O-Methylcafestol of green and roasted coffee, respectively. The collaborative study has shown that mass fractions also between 20 mg/kg to 40 mg/kg can be successfully analysed depending on the laboratory equipment. The compliance assessment process is not part of this document.

ČSN EN 14105 Tento dokument specifikuje metodu pro stanovení obsahu volného glycerolu a reziduálních mono-, di- a trigly-ceridů v methylesterech mastných kyselin (FAME). Celkový obsah glycerolu se poté vypočítá ze získaných výsledků. Za popsaných podmínek jsou meze stanovitelnosti 0,001 % (m/m) pro volný glycerol, 0,10 % (m/m) pro všechny glyceridy (mono-, di- a tri-). Tato metoda je vhodná pro FAME vyrobené z řepkových, slunečnico-vých, sójových, palmových a živočišných olejů a tuků a jejich směsi. Není vhodná pro FAME vyrobené nebo obsahující deriváty kokosového a palmojádrového oleje kvůli překryvu píků různých glyceridů.

ČSN EN 17308 This document specifies two different methods for the quantitative estimation of non-metallic content remaining adhered to the steel wire obtained from the recovery of materials from end-of-life tyres. The pyrolysis method is considered as the reference method while the hydrostatic method is considered as an in situ method. This document includes sample collection and the preparation of representative samples based on a sampling plan for the purpose of their characterization. This document does not apply to the operational performance or fitness for use of the materials which are deemed to be a function of agreements between the manufacturer and the customer. This document does not apply to address all the safety concerns, if any, associated with its use. This document does not establish appropriate safety and health practices and does not determine the applicability of regulatory limitations prior to its use.

ČSN EN ISO 16486-2 This document specifies the physical and mechanical properties of pipes made from unplasticized polyamide (PA-U) in accordance with ISO 16486-1, intended to be buried and used for the supply of gaseous fuels. It also specifies the test parameters for the test methods to which it refers. The ISO 16486 series is applicable to PA-U piping systems, the components of which are connected by fusion jointing and/or mechanical jointing. In particular, this document lays down dimensional characteristics and requirements for the marking of pipes. Pipes conforming to this document are jointed typically by using mechanical, electrofusion or butt fusion techniques.

ČSN P CEN/TS 17670-3 This document gives guidance and requirements for the assessment of conformity of materials (compounds/formulations), products, joints and assemblies in accordance with EN 17670-2 intended to be included in the manufacturer's quality plan as part of the quality management system and for the establishment of certification procedures. NOTE 1 - A test matrix provides an overview of the testing scheme in Annex A, Table A.1. NOTE 2 - If certification is involved, the certification body operating in accordance with EN ISO/IEC 17065 [1] and EN ISO/IEC 17020 [2] is considered to be competent. In conjunction with EN 17670-2 this document is applicable to road gullies.

ČSN EN 17701-2 This document specifies a method for the determination of total contents of arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), nickel (Ni) and zinc (Zn) in aqua regia plant biostimulant digests using inductively coupled plasma-atomic emission spectrometry (ICP-AES). This document is applicable to the blends of fertilizing products where a blend is a mix of at least two of the following component EU fertilising products categories: Fertilizers, Liming Materials, Soil Improvers, Growing Media, Inhibitors, Plant Biostimulants, and where the following category Plant Biostimulants is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If Plant Biostimulants is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a blend of fertilizing products is composed of components in equal quantity or in case the component EU fertilising products used for the blend have identical formulations, the user decides which standard to apply. This method is applicable to aqua regia digests prepared according to EN 17701-1:2024. The method can be used for the determination of other elements, provided the user has verified the applicability.

ČSN EN 17703 This document specifies a method for verifying that hexavalent chromium (Cr(VI)) is not present in plant biostimulants. This document is applicable to all types of plant biostimulants (solid and liquid) used in agriculture. The method specified is suitable to quantify the chromium (VI) content in plant biostimulants down to 2 mg/kg. The results obtained from this method are strictly dependent on the extraction conditions. Results obtained by using other extraction procedures (extraction solution, pH, extraction time, etc.) are not comparable with the results produced by the procedure specified in this document. This document is applicable to the blends of fertilizing products where a blend is a mix of at least two of the following component EU fertilising products: Fertilizers, Liming Materials, Soil Improvers, Growing Media, Inhibitors, Plant Biostimulants and where the following category Plant Biostimulants is the highest percentage in the blend by mass or volume, or in the case of liquid form by dry mass. If Plant Biostimulants is not the highest percentage in the blend, the European Standard for the highest percentage of the blend applies. In case a blend of fertilizing products is composed of components in equal quantity or in case the component EU fertilising products used for the blend have identical formulations, the user decides which standard to apply.

ČSN EN 17706 This document specifies a method for extraction, separation, and determination of inorganic arsenic (iAs) in plant biostimulants using anion-exchange high performance liquid chromatography (HPLC) or ion chromatography (IC) coupled to ICP-MS. This document is applicable to the blends of fertilizing products where a blend is a mix of at least two of the following component EU fertilising products categories: Fertilizers, Liming Materials, Soil Improvers, Growing Media, Inhibitors, Plant Biostimulants, and where the following category Plant Biostimulants is the highest percentage in the blend by mass or volume, or in the case of liquid form by dry mass. If Plant Biostimulants is not the highest percentage in the blend, the European Standard for the highest percentage of the blend applies. In case a blend of fertilizing products is composed of components in equal quantity or in case the component EU fertilising products used for the blend have identical formulations1, the user decides which standard to apply.
