What is ISO 16993 - Solid biofuels — Conversion of analytical results from one basis to another about?
ISO 16993 gives formulae that allow analytical data relating to solid biofuels to be expressed on different bases in common use. Consideration is given to corrections that can be applied to certain determined values for solid biofuels prior to their calculation to other bases.
In Annex A, tools for integrity checks of analytical results are given. In Annex B, conversion factors for calculation into other units are given. Annex C is a guideline for the use of validation parameters as can be found in ISO/TC 238 analytical standards.
Who is ISO 16993 - Solid biofuels — Conversion of analytical results from one basis to another for?
ISO 16993 on Solid biofuels — Conversion of analytical results from one basis to another is useful for:
- Solid biofuels industry
- Analytical data handling agencies
Why should you use ISO 16993 - Solid biofuels — Conversion of analytical results from one basis to another?
In the International Standards covering the analysis of solid biofuels, it is generally specified that the determination is intended to be carried out on the air-dried or in air-equilibrated general analysis test sample prepared according to ISO 14780.
However, in making use of these analyses, it is necessary to express the results on a dry basis and sometimes, also on some other basis. The bases in common use for solid biofuels are “air-dried” (sometimes stated as “as determined”), “as received” (sometimes stated “as sampled” or “as delivered”), “dry”, and “dry, ash-free”.
In order to convert an analytical result expressed as one basis to another basis, it is multiplied by a factor calculated from the appropriate formulae (see Table 1), after insertion of the requisite numerical values into the formula in a question.
ISO 16993 lets you express the analytical data and convert it from one basis to another for solid biofuels.
