Standard gas is a term in the gas industry. Standard substances are measurement standards with uniform concentration, good stability, and accurate measurement values. They play a fundamental role in reproducing, storing, and transmitting measurement values. They are used in the fields of physics, chemistry, biology, and engineering measurement to calibrate measuring instruments and processes, evaluate the accuracy of measurement methods and the detection capabilities of testing laboratories, determine the characteristic values of materials or products, and perform value arbitration.
