Historical Version s - view previous versions of standard. Work Item s - proposed revisions of this standard. More D Over the years, the use of peat as a fuel has been on the decline for numerous reasons, however it is still being used as a fuel in some parts of the world. Peat typically has high a water content, thus when being used as a fuel, the peat must first be air dried in order to reduce the water content.

The ash content is one of several parameters used to classify peat as detailed in Classification D Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results.

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Test Method D provides for determining the water moisture content in mineral soils and rock. For general classification purposes, Method A is used to determine the water content, ash content, and organic material.

When the peat is being used as a fuel, Method B is used to determine the water content, ash content and organic material. This method is used for general purposes and should not be used when the peat or organic soils are being used or evaluated for use as a fuel.

This method is used when the peat or organic soil is being used as or evaluated for use as a fuel. No other units of measurement are included in this standard. In addition, they are representative of the significant digits that generally should be retained.

It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

The moisture content is expressed either as a percent of the oven dry mass or of the as-received mass. This method provides a more stable sample, the air-dried sample, when tests for nitrogen, pH, cation exchange, and the like are to be made. The substance remaining after ignition is the ash. The ash content is expressed as a percentage of the mass of the oven-dried sample. Organic matter is determined by subtracting percent ash content from one hundred. Atlanta Toggle navigation.
