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:
- Manufacturers of bioproducts (for example- starch and sugar)
- Bio-based products testing laboratories
- Pharmaceutical companies
- Healthcare sectors
Why should you use BS EN 17351?
Bio-based products from forestry and agriculture have a long history of application, such as paper, board and various chemicals and materials. The term ‘bio-based’ means 'derived from biomass'. Bio-based products (bottles, insulation materials, wood and wood products, paper, solvents, chemical intermediates, composite materials, etc.) are products that are wholly or partly derived from biomass. It is essential to characterize the amount of biomass contained in the product by, for instance, its bio-based content or bio-based carbon content.
BS EN 17351 aims to specify the method for the determination of oxygen content in bio-based products using an elemental analyser. BS EN 17351 provides the reference test methods for laboratories, producers, suppliers, and purchasers of bio-based products. BS EN 17351 can also be useful for authorities and inspection organizations.
