Protective Clothing Liquid Static Pressure Resistance Tester
Category：Protective Clothing Tester
Introduction
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

FAQ
(1) What is this product?
It is a testing instrument that measures the static liquid pressure resistance of chemical protective fabrics.
(2) What is this product used for?
It evaluates the ability of protective clothing fabrics to resist penetration by acidic and alkaline liquids.
(3) What is the working principle of this product?
A test liquid applies continuous pressure from below the fabric sample until three points of penetration occur; the liquid column height at this moment represents the fabric’s resistance.
(4) Why is this product important?
It ensures protective clothing provides adequate chemical resistance, safeguarding users from exposure to hazardous substances.
(5) What industries is this product suitable for?
Protective clothing manufacturing, chemical industry safety, quality control laboratories, R&D institutions, and regulatory compliance testing.
