Описание (английский):

ISO 16993:2016 gives formulae which allow analytical data relating to solid biofuels to be expressed on the 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.

Overview - EN ISO 16993:2016 (Solid biofuels conversion)

EN ISO 16993:2016 (ISO 16993:2016) provides standardized formulae to convert analytical results for solid biofuels between commonly used reporting bases: as‑analysed (air‑dried), as‑received, dry, and dry, ash‑free (daf). The standard explains required corrections for parameters that are directly affected by moisture (notably hydrogen and net calorific value) and supplies informative Annexes with integrity checks, unit conversion factors and guidance on validation parameters. EN ISO 16993:2016 is intended to ensure consistent, comparable reporting of analytical data across laboratories, fuel producers and users.

Key topics and technical requirements

Conversion formulae: Table 1 contains the general formulae to calculate multiplication factors for converting analytical values among bases (ad, ar, d, daf).

Moisture handling: Details when and how to apply moisture-related corrections before or after basis conversion.

Hydrogen correction: Specifies removal of moisture‑bound hydrogen from air‑dried results before conversion (uses a factor derived from water composition - shown in the standard).

Oxygen calculation: Oxygen on a dry basis may be calculated by difference using carbon, hydrogen, nitrogen, sulfur, chlorine and ash results.

Net calorific value (NCV): NCV reported on a moist basis includes a heat-of-vaporization correction (24.43 J/g per percentage point of moisture). The standard prescribes how to undo and reapply this correction when changing bases.

Integrity and validation tools:

Annex A: tools for integrity checks of analytical results (consistency checks).
Annex B: tables with units and conversion factors.
Annex C: guidance on validation parameters consistent with ISO/TC 238 analytical standards.

Normative references: The standard references analytical methods such as ISO 16948, ISO 16994, ISO 18122, ISO 18125, and ISO 18134 parts.

Applications - who uses EN ISO 16993:2016

Analytical laboratories reporting solid biofuel composition and calorific values.

Fuel producers and traders who must present product specifications on different contractual bases (dry, as‑received, daf).

Power plant operators and boiler manufacturers for fuel quality assessment and combustion calculations.

Regulators and standards bodies harmonizing test reports and compliance data.

Quality managers implementing consistent reporting and data exchange.
