 YS-704 Protective Clothing Molten Metal Splash Tester

【Scope of Application】
This instrument is suitable for metal smelting safety protection and quality supervision inspection agencies. It meets various requirements for testing the heat resistance and penetration protection of protective clothing against molten metal splash. It provides a scientific and reliable basis for the development of protective clothing, quality control during production, and performance detection during use.

【Compliance Standards】

• FZ/T 64083-2021 Fabrics for protection against molten metal splash

• GB 8965.3-2022 Protective clothing — Protective clothing against molten metal splash

• ISO 9185:2007 Protective clothing — Assessment of resistance of materials to molten metal splash

• ISO 11612

【Test Principle】
A specific mass of molten metal is poured onto a specimen placed at a specific angle. The damage to the specimen is evaluated by recording the changes in the PVC film attached to the back of the specimen after pouring. Based on the test results, the mass of the poured metal is calculated to determine the protection level of the specimen.
