Introduction
Photomicrograph of RIC08 round robin sample (Australia, Bowen Basin)
The Standardization WG is the longest running working group of Commission 1. Its purpose is to organize and evaluate round robin exercises related to analysis procedures, recent discussions and definitions/classifications established or to be established by the ICCP.
The working group has been holding round robins on lignite, sub-bituminous and bituminous coals with varying emphasis. Reflectance analysis, maceral group, maceral sub-group and maceral analyses or a round robin on a set of glass standards were topics of the ring analyses. The results from the round robins inter alia established experimental data for the reproducibility, contributed to the idea of the ICCP Accreditation Program and caused the ICCP to have its own reflectance standards against which other standards can be calibrated.
The working group was originally convened Carl Ottenjann (as the Standardization of Analyses Working Group) then by the late Werner Pfisterer followed by the late Walter Pickel, Harold Read, Walter Pickel and Ivana Sykorova and in 2022 by Stavros Kalaitzidis replacing Walter.
Activities
After the first Working Group report by Carl Ottenjann in Oviedo 1983 the following Standardization Working Group round robin exercises (RIC) have been held:
RIC83, RIC85, RIC87, RIC92, RIC93, RIC99, RIC00, RIC03, RIC08 and RIC2010.
RIC2010
If you are willing to run the RIC2010 you are welcome to do so and submit the results to walter.pickel@organicpetrology.com.
The exercise consists of a pdf file with images with marked fields that you are requested to assign to a vitrinite subgroup: telovitrinite, detrovitrinite or gelovitrinite according to vitrinite 1994 ICCP system (ICCP; 1998: The New Vitrinite Classification (ICCP System 1994) – Fuel, 77: 349-358). The exercise also consist of an excel sheet where you are expected to report your results and send them back to the organizer and detailed instructions to perform the exercise.
