20/30411833 DC

This standard 20/30411833 DC BS EN 17505. Soil and waste characterization. Temperature dependent differentiation of total carbon (TOC400, ROC, TIC900) is classified in these ICS categories:

• 13.080.10 Chemical characteristics of soils
• 13.030.10 Solid wastes

This document specifies a method for the differentiated determination of the organic carbon content (TOC₄₀₀) which is released at temperatures up to 400 °C, the residual oxidizable carbon (ROC) (including e.g. lignite (brown coal), hard coal, charcoal, black carbon, soot) and the inorganic carbon (TIC₉₀₀) which is released at temperatures up to 900 °C.

The basis is the dry combustion to CO₂ in a in the presence of oxygen using temperatures ranging from 150 °C to 900 °C in dry solid samples of soil, soil with anthropogenic admixtures and solid waste (see Table 1) with carbon contents of more than 1 g per kg (0,1 % C) (per carbon type in the test portion).

Alternatively, the method specified in Annex B may be applied.
