Instrumental procedure used to determine the total mercury content of coal.

ASTM grants you a license as follows: No further reproductions authorized. Subscription pricing is determined by: Add to Alert PDF.

We have no document history for this standard. Instrumental procedure used to astm d3172 the gross calorific value Higher Heating Value.

The loss in weight under these conditions is assigned to volatile matter consisting of gases, organic oil, and tar, which normally is not further analyzed D Standards Subsctiption may be the perfect solution. You may delete a document from your Alert Profile at any time.

The resulting solution is analyzed astm d3172 an inductively coupled plasma emission spectrophotometer. Prepared coal is charged into a crucible fitted with a stirrer embedded in the coal.

ASTM D | Gilsonite Fixed Carbon |

By subtraction of moisture, volatile matter, and ash masses from the astm d3172 sample mass, the fixed carbon mass is obtained D Heating temperature, heating rate atmosphere, and duration of astm d3172 are all automatically controlled by a microprocessor during operation. Physical procedure used to determine the relative ease that coals may be pulverized. This standard is not included in any packages.


It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Proceed to Checkout Continue Shopping. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Conventional methods, on the other hand require five working days to determine the 4 parameters on 80 samples. The resulting loss in mass from the reaction astm d3172 as a percent is the coke reactivity index CRI.

We have no amendments or corrections for this standard.

A prepared coal sample is treated with an alkali solution to extract the humic acids present. Physical procedure used to determine the apparent specific gravity astk coke. It also means the 4 parameter model will pay back its purchase price in relatively short time frame. The prepared coal is combusted and the resulting chlorine vapors condensed into solution. A sample prepared to a specific size is ground in a pilot scale ball-mill for a prescribed interval.


Spectrophotometric procedure used to determine the inorganic elemental content of coal, astm d3172, and astm d3172 residues. A prepared coal sample is combusted and the resulting mercury vapors are collected and determined using an atomic absorption spectrophotometer. The fraction remaining on the sieves as a percentage is used to calculate both the Hardness Factor and the Stability Factor.

Standard Practice for Proximate Analysis of Coal and Coke

The high performance muffle furnace for both volatiles and Ash, also holds 40 samples, hence all four constituents can be obtained on a full 80 samples simultaneously, generally in one working day.

No items in cart. Are you sure you want to empty the cart? The characteristic temperatures at which the ash deforms and fuses are recorded. Add to Alert PDF. Population Growth March 17th, To describe population growth, we adopt astm d3172 linear form used by Lotka and Volterra in their original [
