Qinsun Hydrostatic Pressure Tester Sample Thickness Requirements

Author:QINSUN Released in:2023-08 Click:98

Qinsun hydrostatic pressure tester is a test equipment independently developed and produced by our company qisnun Precision Electromechanical Technology Co., Ltd. This is a cost-effective and comprehensive after-sales service. It is suitable for melt-blown fabric testing, outdoor sportswear waterproof testing, umbrella testing, waterproof fabric testing, jackets, medical clothing protective material liquid permeability testing , used to assess the sealing performance of the material.

Applicable standards:

GB/T 4744, FZ/T01004, AATCC 127, ERT 120-1 160-0, BS EN20811/3321/3424, AFNOR G07-057, ISO 811, JIS L1092A, JIS L1092.B-a, JIS L1092 B-b, ASTM F903C, ASTM F1670, ASTM F1671, EN 1734, ISO 1420

Principle of the test:

1. Pressurization method: Hydrostatic pressure on the fabric is used to represent the resistance encountered bywater passing through the fabric. Under standard atmospheric conditions, one side of the sample bears a continuous increase in water pressure until water seepage occurs at three locations and record the pressure at this time.

2. Sustained Pressure Timing Method: Under specified conditions, one side of the coated fabric sample to be tested is subjected to continuously increasing water pressure until the specified water pressure value is reached. Within the allotted time, observe for water penetration or continue to pressurize until water penetration occurs.

Main parameters:

1. Sample thickness: 40mm;

2. Test pressure: 0-5000mbar (5000cmW.G);

3. Test area: 100cm2 (optional 10cm2, 19.63cm2, 26cm2, 28cm2);

4. Compressed air requirement: 6-8 bar (clean and dry air);

5. Alarm duration: 0-9999 min (adjustable depending onn pressure or time).
