Testing Standard of Carbon Sulfur Analyzer and Tungsten Granule——Technical Requirements

Generally speaking, carbon sulfur analyzer refers to the generic terms of the instruments which are used to analyze the content of carbon and sulfur of the ferrous metallic material. This type of equipment is easy to operate, with the efficient and high-precision analysis results and other excellent characteristics. It is widely used in the detection of carbon, sulfur and sulfur dioxide content of metals, minerals, ceramics and other substances. The working principles of the instrument are follows: tungsten granule is added to the a certain weight sample as a flux, and then placed in a high-frequency heating furnace for a high temperature combustion, carbon and sulfur of samples will react with oxygen, then produce carbon dioxide and sulfur dioxide, entering to the testing room of carbon dioxide and sulfur dioxide through the gas path system  with the carrier gas, and then analyze the content of carbon dioxide and sulfur dioxide by using the measured light intensity absorption. Finally, the data obtained content of carbon and sulfur. The whole machine adopts modular design, power supply system consists of two modules, which can avoid dust, and it is simple and reliable.

Testing standards of carbon sulfur analyzer and tungsten granule mainly consists of five parts: the technical requirements, test conditions, methods of identifying, management of the results of treatment as well as the re-testing period. In appearance of the instrument, it should be marked with the name of instrument, model number, manufacturer's name, license logo and number of manufacturing measuring instruments, date of manufacturing as well as the number of instruments. The appearance of the instrument cannot have any mechanical damage, and each member should be in a solid state, the function keys are intact, which is able to work properly.

For different measuring range, the error of the average value and standard value of the testing results cannot exceed the standard requirements. The indicating error of carbon content which is more than 0.0010 to 0.0100 is ± 0.0005%, the indicating error which is between 0.010 to 0.100 is ± 0.005%, and error of indication between the 0.100 to 1.000 is ± 0.010%, indication error between 1.00 to 3.00 is ± 0.03%. The standard of sulfur content is the same as the carbon content, the different is that the error of indication of sulfur between 0.100 ~ 0.300 is ± 0.010%.
