The resistance tester for protective clothing materials against metal molten liquid penetration
Category:Other
Introduction
The Resistance Tester for Protective Clothing Materials Against Metal Molten Liquid Penetration is designed to evaluate the protective performance of fabrics and composite materials against burns caused by molten metal splashes. The instrument is developed in accordance with international and national standards including ISO 9150, EN 348, GB/T 17599, AQ6103, and GB 8965.2.
During testing, a controlled amount of molten metal is poured onto a sample placed at a specific angle. A PVC film attached to the back of the sample records the damage caused by the metal splash. The process can be repeated with different molten metal quantities to determine the material’s resistance. Temperature control, sample tilting, and splash collection are fully automated for precise, reproducible results.
This tester is widely used in protective clothing manufacturing, textile testing labs, research institutes, and safety compliance evaluations.
