Jiexiu Double Road gas measuring cabinet
Standard CJ 274 - 2008 issued after the implementation of inspection center after years of regulator of quality inspection work, through the voltage regulator of rubber diaphragm resistance test results of gas properties (test solvent for B solution) statistics, more than 50% of the obtained rubber diaphragm can meet higher standards for the conclusion. At the same time, in the provisions of the new standard, the test solvent for the rubber diaphragm of the regulator with non coal gas as the source of gas is changed into a less liquid pentane. Therefore, in order to adapt to changes in the source of this industry development trend at the same time, to ensure and promote the adjustment to further improve the product quality of the rubber diaphragm pressure regulator, standard GB 27790 - 2011 on the gas resistance of rubber diaphragm indicators for the new regulations: rubber diaphragm pressure regulator in the standard room temperature in the liquid (provisions liquid pentane or B solution) for 72 h, 5 min after the removal rate of change of mass and volume change rate should not be greater than 15%; after 24 h storage, the rate of change in mass and volume changes in dry air rate should not be greater than 10%.
