BS EN 17351:2020 生物基产品 使用元素分析仪测定氧含量

What is BS EN 17351 about?    BS EN 17351 discusses bio-based products that help to determine the oxygen content using an elemental analyser. BS EN 17351 specifies a direct method for the determination of the total oxygen content in bio-based products using an elemental analyser. The scope is limited to products containing the elements carbon, hydrogen, oxygen, nitrogen, chloride, bromide and iodide without fluoride, representing at least 95 % of the composition of the product to be analysed.   Note 1: Bio-based materials can contain both organic and inorganic components. According to the current state of the art, it is not possible by isotopic measurements to establish a distinction between oxygen originating from biomass and oxygen originating from non-biomass.  Note 2: Although BS EN 17351 has been drafted for determinations dealing with bio-based content, it can be also used as a standalone standard for the determination of oxygen in organic compounds.  Note 3: For BS EN 17351 , the unit “% (m/m)” is used to represent the oxygen content of a material.  Who is BS EN 17351 for?   BS EN 17351 on bio-based products is useful for:

Bio-based products. Requirements for Business to Business communication of characteristics using a Data Sheet

EN 16848:2016 生物基产品.使用数据表的业务对企业特性通信的要求

This European Standard specifies requirements for transparent and non-misleading business to business communication of characteristics of bio-based products by means of a specific Data Sheet. It does not specify requirements for bio-based products. This European Standard is intended to be used as a tool to generate and transfer information in the value chain and/or as an input for product-specific standards and certification schemes. Business to consumer communication is covered by prEN 16935.[1]

Bio-based products - Requirements for Business to Business communication of characteristics using a Data Sheet

EN 16751:2016 生物基产品-可持续性标准

This European Standard sets horizontal sustainability criteria applicable to the bio-based part of all bio-based products, excluding food, feed and energy, covering all three pillars of sustainability; environmental, social and economic aspects. If the product is partly bio-based, this European Standard can only be used for the bio-based part since it does not address non-bio-based (fossil, mineral) parts of a product. This European Standard can be used for two applications; either to provide sustainability information about the biomass production only or to provide sustainability information in the supply chain for the bio-based part of the bio-based product. This European Standard sets a framework to provide information on management of sustainability aspects. This European Standard cannot be used to make claims that operations or products are sustainable since it does not establish thresholds or limits. This European Standard can however be used for business-to-business (B2B) communication or for developing product specific standards and certification schemes.

prEN 17980 藻类和藻类产品 采样 采样程序和采样协议定义指南

This document specifies a set of principles and rules that algae producers, algae products industries, laboratories or other entities that collect algae and algae products samples must follow for the definition of their own sampling programs and sampling protocols. In the context of this document, algae are a functional group that include microalgae, macroalgae, cyanobacteria and Labyrinthulomycetes. As algae and their production processes are so diverse, this document does not define a specific sampling program and/or a specific sampling protocol. Instead, this document specifies the aspects that an organization shall consider when defining its own sampling program and protocol. This document describes when and how a representative sample shall be drawn. For guidance on sample preparation of dry and wet samples of micro- and macroalgae, and algae-based products, please refer to EN 17605:2022. This document is to be used for the collection of samples for lot characterization for commercial or legal/regulatory purposes. However, this document can also be used for any type of sampling of algae, including samples for quality control during production.
