Scope
Main technical content: The geotextile permeability tester is a dedicated inspection equipment used to determine the vertical permeability performance of geotextiles and related products under the constant water head method. At present, there is no effective technical basis for geotextile permeability testers, which makes it impossible to ensure the unified and accurate reliability of their measurement traceability. Therefore, in order to meet the traceability requirements of geotextile permeability testers, it is urgently necessary to formulate a calibration method for geotextile permeability testers. This standard is mainly applicable to the daily calibration work of geotextile permeability testers. The standard specifies the calibration methods for various measurement indicators, including the calibration of the scale error of the water level indicator, the calibration of the inner diameter error of the clamping device, the calibration of the timing error of the timer, and the calibration of the capacity error of the measuring cylinder. The scale error of the water level indicator, the inner diameter error of the clamping device, the timing error of the timer, and the capacity error of the measuring cylinder of the MTSY-01 type geotextile permeability tester are calibrated according to this calibration method; the scale error of the water level indicator, the inner diameter error of the clamping device, the timing error of the timer, and the capacity error of the measuring cylinder of the TSY-1 type geotextile permeability tester are calibrated according to this calibration method; the scale error of the water level indicator, the inner diameter error of the clamping device, the timing error of the timer, and the capacity error of the measuring cylinder of the TH-020 type geotextile permeability tester are calibrated according to this calibration method; the relevant parameters of the above equipment are calibrated according to the provisions of this calibration
