EN 15440-2011固体回收燃料.生物质含量测定方法

This European Standard specifies three normative methods for the determination of the biomass fraction in solid recovered fuel, and when to use each method. The methods are the selective dissolution in a hydrogen peroxide/sulphuric acid mixture, the manual sorting method and the method based on the 14C content.

DIN EN 16640-2017生物基质产品.生物基碳含量.使用放射性碳方法测定生物基碳含量;德文版本EN 16640-2017

This European Standard has been developed with the aim to specify the method for the determination of bio-based carbon content in bio-based products using the 14C method. This method using the 14C method is based on the analytical test methods used for the determination of the age of objects containing carbon. This European Standard provides the reference test methods for laboratories, producers, suppliers and purchasers of bio-based product materials and products. It may be also useful for authorities and inspection organizations. Part of the research leading to this document has been performed under the European Union Seventh Framework Programme (see http://www.biobasedeconomy.eu/research/kbbpps/).This document is based on EN 15440 [1] prepared by CEN/TC 343, \"Solid recovered fuels\", EN ISO 13833 [2], prepared by ISO/TC 146 \"Air Quality\" and CEN/TC 264 \"Air Quality\", and CEN/TS 16137 [3], prepared by CEN/TC 249, \"Plastics\". This European Standard specifies a method for the determination of the bio-based carbon content in products, based on the 14C content measurement. This European Standard also specifies two test methods to be used for the determination of the 14C content from which the bio-based carbon content is calculated: - Method A: Liquid scintillation-counter method (LSC) ; - Method B: Accelerator mass spectrometry (AMS). A third method, Method C: Beta ionization (BI) can also be used for the determination of the 14C content and is described in Annex D (informative). The bio-based carbon content is expressed by a fraction of sample mass or as a fraction of the total carbon content. This calculation method is applicable to any product containing carbon, including bio composites. This European Standard does not provide the methodology for the calculation of the biomass content of a sample see prEN 16785-1 and prEN 16785-2.

BS EN 973-2009人消耗用水的处理用的化学物质.离子交换器再生用氯化钠

This European Standard is applicable to sodium chloride intended for use only in water treatment apparatus, for the regeneration of ion exchangers, intended for water for human consumption. It describes the characteristics and specifies the requirements and the corresponding test methods for sodium chloride. It gives information on its usein water treatment.
