ČSN EN ISO 17422 This document provides a structure for inclusion of environmental aspects in standards for plastics products. It proposes an approach which is directed at minimizing any adverse environmental impact without detracting from the primary purpose of ensuring adequate fitness for use of the products under consideration. The guidance provided by this document is intended primarily for use by standards writers. Over and above its primary purpose, however, this document provides guidance of value to those involved in design work and other activities where environmental aspects of plastics are being considered. NOTE - This document is intended to promote the following practices: a) the use of techniques for identifying and assessing the environmental impact of technical provisions in standards, and for minimizing their adverse effects; b) the adoption of good practices such as: - procedures for pollution avoidance, e.g. through end-of-life options and its proper management; - material and energy conservation in the light of the intended use (and foreseeable misuse) of the product; - safe use of hazardous substances; - avoidance of technically unjustifiable restrictive practices; - promotion of performance criteria rather than exclusion clauses such as are based, for example, only on chemical composition criteria; - use of renewable resources and minimization of the use of non-renewable resources, if the life cycle assessment shows favourable; c) the adoption of a balanced approach in standards development to issues such as environmental impact, product function and performance, health and safety, and other regulatory requirements; d) the regular review and revision of existing standards in the light of technical innovations, permitting improvement in the environmental impact of products and processes; e) the application of life cycle analytical approaches wherever applicable and technically justifiable.

ČSN EN ISO 11343 This document specifies a dynamic impact wedge method for the determination of the cleavage resistance under impact loading of high-strength adhesive bonds between two adherends, when tested under specified conditions of preparation and testing. This test procedure does not provide design information. The method allows a choice of sheet metal or fibre reinforced plastic substrates corresponding to those materials frequently used in industry, such as for automotive applications.

ČSN EN 15254-4 (73 0855) Tento dokument poskytuje návod, případně definuje postup při změnách určitých parametrů a faktorů, spojených s návrhem požárně odolných zasklených prvků, zkoušených podle EN 1364-1:2015, a klasifikovaných podle EN 13501-2. Rozšířená aplikace požárně odolných zasklených prvků je založena na výsledcích zkoušky. Tato norma platí pouze pro svisle instalované požárně odolné zasklené prvky. Tato norma neplatí pro dveřní sestavy a pro otevíratelná okna, zkoušené podle EN 1634-1 a neplatí pro závěsové stěny - celé sestavy a závěsové stěny - částečné sestavy podle EN 1364-3 a EN 1364-4. Vyloučeny jsou sestavy skleněných tvárnic, skleněných dlaždic a profilované sklo podle definice v EN 1051-1 a EN 572-7. V současné době není k dispozici dostatek informací, aby bylo možno stanovit pravidla rozšířené aplikace pro tyto výrobky.

ČSN EN ISO 18218-2 This document specifies a method for determining alkylphenols (nonylphenol and octylphenol) and alkylphenol ethoxylates (nonylphenol ethoxylate and octylphenol ethoxylate) in leather and process auxiliaries. The analysis is based on high-performance liquid chromatography (HPLC) or gas chromatography-mass spectrometry (GC-MS). The analysis of the alkylphenol ethoxylate is made by cleaving the alkylphenol ethoxylate and measuring the released alkylphenol.

ČSN EN ISO 4049 This document specifies requirements for dental polymer-based restorative materials supplied in a form suitable for mechanical mixing, hand-mixing, or intra-oral and extra-oral external energy activation, and intended for use primarily for the direct or indirect restoration of the teeth and for luting. The polymer-based luting materials covered by this document are intended for use in the cementation or fixation of restorations and appliances such as inlays, onlays, veneers, crowns and bridges. This document does not cover those polymer-based luting materials that have an adhesive component within the structure of the material (see ISO/TS 16506). The document does not cover polymer-based materials intended to prevent caries (see ISO 6874), core materials or those used for veneering metal sub-frames (see ISO 10477).

ČSN EN 14619 This document applies to kick scooters that can only be propelled by the muscular activity of a user with a body mass of more than 20 kg and less than 100 kg. To reduce the risk of injuries to both the user and third parties during intended use this standard specifies safety requirements, test methods, marking, and information supplied by the manufacturer. Kick scooters for use by users of less than 20 kg do not belong to the scope of this document. They are toys. It should be noted that there are two types of scooters for the weight group 20 kg to 50 kg - those classified as sports equipment for use on public roads and path ways (this European Standard) and those classified as toys for domestic use (according to EN 71-1).
