The Protective Clothing Liquid Static Pressure Resistance Tester is designed to evaluate the resistance of breathable chemical protective clothing fabrics against penetration by acidic and alkaline liquids under static pressure. This instrument measures the fabric’s ability to withstand liquid pressure, providing critical performance data for protective apparel in chemical hazard environments.
Application
(1) Protective clothing manufacturers – verify the liquid resistance performance of chemical protective fabrics.
(2) Quality control laboratories – ensure production batches meet GB 24540-2009 standards.
(3) Research and development – assess new fabric materials or treatments for chemical protection.
(4) Third-party testing organizations – certification and compliance testing for chemical protective clothing.
(5) Safety regulators – confirm protective clothing meets statutory safety requirements.
Standards
(1) GB 24540-2009: Protective Clothing for Acid and Alkali Chemicals – Performance Requirements
Parameters
| Parameter | Specification |
|---|---|
| Test Liquid | Acidic and alkaline solutions; e.g., 80% H₂SO₄ |
| Liquid Pressure Rise Rate | 60 ± 3 cm/min |
| Maximum Pressure | >150 mm liquid column (for 80% H₂SO₄) |
| Measurement Range | 0–150 mm liquid column (for 80% H₂SO₄) |
