Scope of Application

【Operating Instructions】

This instrument is developed according to the national standard GB 24540-2009 “Protective clothing — Protective clothing against chemicals — Test methods”. It is mainly used to test the resistance of fabric‑based protective clothing against acids and alkalis to liquid hydrostatic pressure. The resistance of the test reagent to penetrate through the fabric is expressed by the liquid hydrostatic pressure value that the fabric withstands.
