Introduction
In recent years, coal composition analysis and physical properties of materials measurement standards has been widely used in coal laboratory test results to ensure that coal
Accuracy and comparability played a good role. However, due to some users can not properly use coal reference materials, resulting in "standard value" in
To some extent it has been "distorted" the use, affecting the measurement accuracy of the results. In addition to the calibration instrument and monitor the testing process, the standard coal
Application of reference material in other areas, such as research and test methods Test methods and other aspects of confirmation is not known for a number of users. In order to regulate coal
Proper use of standard substance, ensure coal test results between laboratories provide accurate and reliable, ensure the establishment of a reliable field test in the coal
The traceability chain, and expand the scope of application of standard coal substance formulated standards.
This standard gives a kind of standard material test program in various applications, the basic methods of data processing and statistical analysis, and pass judgment
Principles, the user can use the material object based on specific criteria and requirements, develop more specific, the applicable test procedures and establish statistical knot
Criterion fruit.
Analysis of coal composition and physical properties
Measurement Standards Application Guidelines
1 Scope
This standard gives the coal component analysis and physical property measurement instrument calibration standard or calibration material, equipment performance evaluation, test
Applications and Data Analysis Methods and guidelines confirm quality control and other aspects of the test.
This standard applies to coal composition analysis and physical property measurement standard material for various applications.
NOTE. coal composition analysis and physical properties measurement reference materials including coal and ash reference material, hereinafter referred to as the coal reference materials.

MT/T 1013-2006 Inspection of coal Uncertainty Evaluation Guide
3 coal reference material characteristic values \u200b\u200bCharacteristics and Applications category
3.1 traceable to SI units, with long-term stability of value
Classical, reliable method of valuation, value is traceable to the SI (International System of Units) units, the standard value is largely unaffected by the oxidative deterioration of coal
The effects of long-term stability, typically the amount of standard coal component substances such as nitrogen and total sulfur in coal, coal arsenic, phosphorus, chlorine, fluorine, Coal Ash
Silicon, aluminum, iron, calcium, magnesium, titanium, potassium, sodium, sulfur and phosphorus.
Such characteristics can be used to measure the standard substance calibration or instrument calibration equipment performance evaluation, test methods and validation studies and
Test quality monitoring.
3.2 traceable to SI units, with a certain measure of stability
Value is accurate and reliable, traceable to SI metric units, the standard value of coal susceptible to oxidative deterioration and change, usually only 1 year
Or longer stability, such as content of the coal calorific value and carbon. They generally increases oxidative deterioration of coal decreased, but the rate of change within a year
Does not exceed the value of the standard uncertainty.
Such characteristics can be used to measure the standard material equipment performance evaluation, test methods and validation studies and test quality monitoring.
3.3 traceable to standard test method, with a certain measure of stability
Setting accurate and reliable traceability to recognized international or national standard test method, commonly referred to as conditional value, having (1-2) years of steady
Qualitative (such as volatile coal, coking indicators) or long-term stability (such as ash, etc.).
Such characteristics can be used to measure the standard material equipment performance evaluation, test methods and validation studies and test quality monitoring.
3.4 traceable to international or national standard, with a certain measure of stability
Value is accurate and reliable, value traceable to recognized international or national standard (national standard methods based on international or value), such as coal,
