sampling and analysis provided for in Subdivision 2.2.3.3.
Aar is the amount of ash in fuel type (i) as a percentage of the as received or as combusted mass of the fuel estimated using the sampling and analysis provided for in Subdivision 2.2.3.3.

Subdivision 2.2.3.3—Sampling and analysis for method 2 under sections 2.5 and 2.6

2.7  General requirements for sampling solid fuels
 (1) A sample of the solid fuel must be derived from a composite of amounts of the solid fuel combusted.
 (2) The samples must be collected on enough occasions to produce a representative sample.
 (3) The samples must also be free of bias so that any estimates are neither over nor under estimates of the true value.
 (4) Bias must be tested in accordance with an appropriate standard (if any).
Note: An appropriate standard for most solid mineral fuels is AS 4264.4—1996 Coal and coke—Sampling—Determination of precision and bias.
 (5) The value obtained from the sample must only be used for the delivery period or consignment of the fuel for which it was intended to be representative.

2.8  General requirements for analysis of solid fuels
 (1) A standard for analysis of a parameter of a solid fuel, and the minimum frequency of analysis of a solid fuel, is as set out in Schedule 2.
 (2) A parameter of a solid fuel may also be analysed in accordance with a standard that is equivalent to a standard set out in Schedule 2.
 (3) Analysis must be undertaken by an accredited laboratory that meets the requirements equivalent to those in AS ISO/IEC 17025:2005. However, analysis may be undertaken by an on‑line analyser if:
 (a) the analyser is calibrated in accordance with an appropriate standard; and
 (b) analysis undertaken to meet the standard is done by a laboratory that meets the requirements equivalent to those in AS ISO/IEC 17025:2005.
Note: An appropriate standard is AS 1038.24—1998, Coal and coke—Analysis and testing, Part 24: Guide to the evaluation of measurements made by on‑line coal analysers.
 (4) If a delivery of fuel lasts for a month or less, analysis must be conducted on a delivery basis.
 (5) However, if the properties of the fuel do not change significantly between deliveries over a period of a month, analysis may be conducted on a monthly basis.
 (6) If a delivery of fuel lasts for more than a month, and the properties of the fuel do not change significantly before the next delivery, analysis of the fuel may be conducted on a delivery basis rather than monthly basis.

2.9  Requirements for analysis of furnace ash and fly ash
  For furnace ash and fly ash, analysis of the carbon content must be undertaken in accordance with AS
