Fabric hydrostatic tester calibration calibration

Fabric hydrostatic pressure tester is used to test the water seepage resistance of medical clothing, compact fabrics, such as canvas, tarpaulin, tarpaulin, tent cloth, rainproof clothing cloth and other materials, which is the key product
independently developed and produced by our standard group (Hong Kong) Co.
, Ltd 。 Applicable standards: GB 19082-2009 Technical requirements for medical disposable protective clothing 5.

1 Water resistance GB 4744-1997 Hydrostatic pressure test for determination of water permeability of textile fabrics GB 4744-2013 Fabric water seepage performance tester AATCC 127, ISO 16603, YYT 0700 Calibration calibration: 1.
Connect the calibration water pipe, the verification water pipe is connected to the copper joint on the right side of the water discharge valve, and open the water discharge valve; 2.
If you want to verify the water pressure value of 0~2M range, the test device should be placed in a lower position to ensure that the water pipe has a vertical height of 2M; 3.
Put a null-free check plate on the test hole; 4.
Press the [Start] button > press the [Stop] button to mark the zero point of the water column, on the water pipe or the corresponding reference ruler; 5.
Select 100cmH2O/min for the rising rate (the purpose is to make the calibration process more than too long); 6.
Press the [Reset] button --> [Start] button to start calibration; 7.
Start the instrument, the water column in the water pipe gradually rises, and compare the height value of the water column in the water pipe and the digital display value of the instrument; 8.
If there are bubbles in the water column in the water pipe, the bubbles must be drained, otherwise the height value of the water column is incorrect
.
