34、dition (ISO 16993:2015), of which it constitutes a minor revision.DIN EN ISO 16993:2016-11 EN ISO 16993:2016 (E) 4 IntroductionIn 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

35、 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 dry basis and sometimes, also on some other basis. The bases in common use for solid biofuels are “air-dried” (sometimes stated as “as d

36、etermined”), “as received” (sometimes stated “as sampled” or “as delivered”), “dry”, and “dry, ash free”.DIN EN ISO 16993:2016-11 EN ISO 16993:2016 (E) 5 1 ScopeThis International Standard gives formulae which allow analytical data relating to solid biofuels to be expressed on the different bases in

37、 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

38、 given. Annex C is a guideline for the use of validation parameters as can be found in ISO/TC 238 analytical standards.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

45、te formulae (see Table 1), after insertion of the requisite numerical values into the formula in question.5 Calculations for analyses of solid biofuels5.1 GeneralMost analytical values on a particular basis can be converted to any other basis by multiplying it by a factor calculated from the appropr

46、iate formula given in Table 1, after insertion of the requisite numerical values into the formula in question. However, for some parameters, there is a direct involvement of the moisture content. In these cases, a correction (as specified in 5.2) of the air-dried result shall be carried out before c

47、alculation to dry basis or dry, ash-free basis. Also, if a result for these parameters expressed on a dry or a dry, ash-free basis is to be recalculated to a moist basis, the corrections stated in 5.2 shall be added back to the actual moist basis after applying the appropriate formula from Table 1.5

48、.2 Extra calculations for hydrogen, oxygen, and net calorific value5.2.1 HydrogenThe hydrogen content determined on the air-dried basis (Had, as analysed) includes both the hydrogen content of the combustible part of the solid biofuel, as well as the hydrogen present in the sample as moisture (total hydrogen content).
