ČSN EN 17427 This document specifies a testing scheme and requirements for the designation of carrier bags of any materials that are considered to be suitable for incorporation into well-managed home composting installations for non-commercial purposes with a home composting cycle of normally at least 12 months. Carrier bags are considered as home compostable in a well-managed system only if all the individual components meet the requirements. The following four aspects are addressed: a) characterization; b) biodegradation in well managed home composting; c) disintegration in well managed home composting; and d) home compost quality. The four aspects, a) to d), are assessing the effects on the biological treatment process and the compost made by it. This document forms the basis for the labelling of carrier bags that are considered to be suitable for the incorporation into well-managed home composting installations. NOTE 1 - Compliance with the requirements of this document by the carrier bags entering the compost does not necessarily imply that a high-quality compost will be produced. This document covers the suitability of carrier bags for the incorporation into well managed home composting installations but does not address regulations that may exist regarding the suitability of anything disposed together with the carrier bag to home composting. This document provides a set of guidance on the parameters, boundaries and processes required to engage in well managed, aerobic, home composting. Alternative composting methods and systems may not provide the conditions necessary for the successful home composting of carrier bags which comply with the requirements of this document. NOTE 2 - Additional general information about home composting is provided in Annex F. The testing scheme and the requirements specified by this document do not apply to worm composting, industrial composting nor community composting. It also does not provide information on the biodegradability of carrier bags ending up in the environment as litter. This document includes a reference to features of well-managed home composting (Annex E). The compost produced via home composting by a private individual is for private use only and not for provision to others, free of charge or in return for payment. Therefore, this document has no value as a marketing authorization or authorization of use of the final compost. NOTE 3 - The testing scheme and evaluation criteria could be the basis for the establishment of suitability to home composting of other products. NOTE 4 - The purpose of testing activity b) is to demonstrate the potential for ultimate biodegradation of the test material when exposed to microbes active under mesophilic conditions (between 15 °C and 45 °C). NOTE 5 - The purpose of testing activity c) is to verify the thickness and/or grammage that allows a full disintegration of the test product in a period consistent with a home composting cycle, under defined environmental conditions. To allow for the potential for variations of local climatic conditions and consumer application of well-managed home composting techniques, lower than optimal temperature profile has been adopted for this test.

ČSN EN 17503 Tento dokument specifikuje různé metody kvantitativního stanovení 16 polycyklických aromatických uhlovodíků v půdách, kalech, upraveném bioodpadu a odpadech s použitím plynové chromatografie nebo vysokoúčinné kapalinové chromatografie. Tato metoda může být používána také pro sedimenty, pokud uživatel ověřil její použitelnost. Mez detekce závisí na stanovovaných látkách, na použitém vybavení, na kvalitě chemikálií použitých pro extrakci vzorku a čištění extraktu. Za podmínek uvedených v tomto dokumentu je možné dosáhnout meze stanovitelnosti od 10 µg/kg (v sušině) pro půdy, kaly a bioodpad do 100 µg/kg (v sušině) pro pevné odpady. U některých specifických vzorků (např. bitumen) nelze dosáhnout meze 100 µg/kg.

ČSN EN ISO 23537-1 This document specifies the requirements, test methods and other provisions for the labelling of adult sized sleeping bags for use in sports and leisure time activities at a limit temperature >= -20 °C regarding thermal characteristics, dimensions and mass. This document describes a method for the assessment of performance in steady-state conditions of a sleeping bag with regard to the protection against cold. NOTE 1 - Sleeping bags without homogeneous fillings designed to provide local extra insulation in certain parts pose issues with the calibration and/or test procedure. Ongoing work continues to provide suitable means of establishing temperature ratings This document does not apply to sleeping bags intended for specific purpose such as military use and extreme climate zone expedition. It does not apply to sleeping bags for children or babies. NOTE 2 - No prediction model exists for the determination of the limiting temperatures based on the thermal resistance of the sleeping bag for children and babies. Moreover, such a model for testing cannot be developed because the necessary controlled sleep trials with children or babies in climatic chambers are, out of ethical reasons, not possible.

ČSN EN ISO 19105 This document specifies the framework, concepts and methodology for conformance testing and criteria to be achieved to claim conformance to the family of applicable standardization documents regarding geographic information and relevant application domains. This document provides a framework for specifying abstract test suites composed of abstract test cases grouped in conformance classes and for defining the procedures to be followed during conformance testing. Conformance can be claimed for data or software products or services or by specifications including any profile or functional standard. The structure of, and relationships between, conformance classes as defined in this document underly a systematic approach to configuration management involving managing dependencies within and between modules.

ČSN EN 13203-5 This document is applicable to gas-fired appliances producing domestic hot water. It applies to both instantaneous and storage gas-fired combined with electric heat pump. It applies to a package marketed as single unit or fully specified by the manufacturer that have: - a heat input not exceeding 400 kW; - a hot water storage tank capacity (if any) not exceeding 2 000 l. EN 13203-1:2015 sets out in qualitative and quantitative terms the performance in delivery of domestic hot water for a selected variety of uses. It also gives a system for presenting the information to the user. The present document sets out a method for assessing the energy performance of gas fired appliances combined with heat pump with electrically driven compressor according to EN 16147. It specifies a number of daily load profiles for each domestic hot water use, kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of different gas-fired appliances to be compared and matched to the needs of the user. Where other technologies are combined with a gas-fired boiler or a water heater to produce domestic hot water, specific parts of EN 13203 apply. The present document does not apply for gas boilers with recovery systems using combustion products as heat source for the electrical heat pump. When the electrical heat pump does not work for domestic hot water production in the summer period, the present standard is not applicable for energy performances assessing, instead EN 13203-2:2022 is applicable.
