ČSN EN 17844 This document describes two methods for determining the content of polycyclic aromatic hydrocarbons (PAH) and one method for determining the content of benzene, toluene, ethylbenzene and xylenes (BTEX) with gas chromatography with mass spectrometric detection (GC-MS). See Annex A (normative) for lists of PAH and BTEX that can be determined with this document. This document is intended to be used for construction products. In a number of cases additional analysis with high performance liquid chromatography (HPLC) can be necessary to determine a number of compounds. To determine PAH multiple liquid-liquid extraction is used to remove interfering compounds, e.g. maltenes. The tests that led to this document were carried out on different types of roofing material, bitumen and bituminous binders as well as asphalt including one tar containing asphalt (see [Van De Weghe at el., 2018] and [García-Ruiz et al., 2020]). The detectability limit of the methods for individual compounds in roofing material, asphalt and tar containing asphalt for PAH is 0,5 mg/kg to 1,5 mg/kg and for BTEX 0,1 mg/kg.

ČSN EN ISO 22097 (73 0341) This document describes a set of procedures for using existing standardized CEN or ISO test and calculation methods to determine the thermal performance of reflective insulation products. This document supports and does not replace existing CEN or ISO test methods. This document applies to any thermal insulation product that derives a proportion of its claimed thermal properties from the presence of one or more reflective or low emissivity surfaces together with any associated airspace(s). It does not replace the existing procedures for the determination of the thermal performance of products already covered by an existing harmonized product standard where the declared value of these products does not specifically include any claims attributable to the emissivity of the facing. It does not, and cannot, give an in-use or design value of thermal performance, but provides standardized information from which these can be determined.

ČSN EN IEC 62056-8-12 This part of IEC 62056 describes the use of DLMSR/COSEM for Low-Power Wide Area Networks (LPWANs). It specifies how the COSEM data model and the DLMSR/COSEM application layer can be used over various LPWAN technologies using an adaptation layer based on IETF RFC 8724, and in particular over LoRaWAN. This profile is intended to be used with LPWANs as defined in IETF RFC 8724, in particular LoRaWAN. Low-Power Wide Area Networks (LPWANs) are wireless technologies with characteristics such as large coverage areas, low bandwidth, possibly very small packet and application-layer data sizes, and long battery life operation. This document does not provide functionality to manage the lower layers of the LPWANs. This part of the DLMSR/COSEM suite specifies the communication profile for Low-Power Wide Area Networks (LPWANs).

ČSN EN ISO 14126 1.1 This document specifies methods for determining the compressive properties, in directions parallel to the plane of lamination, of fibre-reinforced plastic composites, based on thermosetting or thermoplastic matrices. The compressive properties are of interest for specifications and quality-control purposes. The test specimens are machined from a flat test plate, or from suitable finished or semi-finished products. 1.2 Two loading methods and two types of specimen are described. 1.3 This document gives criteria for checking that the combination of test method and specimen design result in valid failures. It is noted that alternative test method/specimen combinations will not necessarily give the same result. 1.4 The methods specify required dimensions for the specimen. Tests carried out on specimens of other dimensions, or on specimens that are prepared under different conditions, can produce results that are not comparable. Other factors, such as the speed of testing, the support fixture used and the conditioning of the specimens, can influence the results.

ČSN EN 13697 This document specifies a test method (phase 2/step 2) and the minimum requirements for bactericidal and yeasticidal and/or fungicidal activity of chemical disinfectants that form a homogeneous physically stable preparation in hard water or - in the case of ready-to-use products - with water in food, industrial, domestic and institutional areas, excluding areas and situations where disinfection is medically indicated and excluding products used on living tissues. This document applies to products that are used for disinfecting non-porous surfaces without mechanical action. This document is applicable at least to the following: a) processing, distribution and retailing of: 1) food of animal origin: i) milk and milk products; ii) meat and meat products; iii) fish, seafood and products; iv) eggs and egg products; v) animal feeds; vi) etc. 2) food of vegetable origin: i) beverages; ii) fruits, vegetables and derivatives (including distilleries and sugar refineries); iii) flour, milling and baking; iv) animal feeds; v) etc. b) institutional and domestic areas: 1) catering establishments; 2) public areas; 3) public transports; 4) schools; 5) nurseries; 6) shops; 7) sports rooms; 8) waste containers (bins); 9) hotels; 10) dwellings; 11) clinically non sensitive areas of hospitals; 12) offices; 13) etc. c) other industrial areas: 1) packaging material; 2) biotechnology (yeast, proteins, enzymes...); 3) pharmaceutical; 4) cosmetics and toiletries; 5) textiles; 6) space industry, computer industry; 7) etc. This document does not apply when the product is applied via an automatic airborne disinfection method; in such cases, see EN 17272. Using this document, it is possible to determine the bactericidal and yeasticidal and/or fungicidal activity of the undiluted product. As three concentrations are tested, in the active to non-active range, dilution of the product is needed and, therefore, the product forms a homogeneous stable preparation in hard water. EN 14885 specifies in detail the relationship of the various tests to one another and to use recommendations. NOTE 1 - The method described is intended to determine the activity of commercial formulations or active substances on bacteria and/or fungi in the conditions in which they are used. NOTE 2 - This method cannot be used to evaluate the activity of products against mycobacteria.
