A Comprehensive Guide To

GT-C94 Protective Clothing Against Molten Metal

In metallurgy, casting, welding, machining, and other industries involving high-temperature molten metal operations, personnel face a very high risk of being burned by splashing high-temperature metal liquids. Therefore, protective clothing and textile materials must undergo strict high-temperature molten metal droplet impact performance testing to ensure that they can still provide effective protection for workers under extreme conditions.

The GT-C94 Protective Clothing Against Molten Metal Tester is a professional device developed precisely for this need. It can simulate the real impact process when high-temperature molten metal droplets contact protective materials, thereby accurately evaluating their thermal protection performance.

I. Application of the Protective Clothing Molten Metal

When working in a high-temperature metal environment, the temperature of molten metal usually reaches above 1000°C. Once it splashes onto the surface of the clothing, even a very small droplet of metal may cause the clothing to be penetrated instantly and burn the skin. Therefore, both international and domestic organizations have formulated strict standards for protective clothing molten metal droplet testing, such as AQ 6103-2007, GB/T 17599, GB/T 8965.2-2009, ISO 9150, and EN 348.

The functions of the GT-C94 Protective Clothing Molten Metal are:

Generate high-temperature molten metal droplets through a controllable metal droplet system

Simulate droplets impacting the material surface with fixed frequency, weight, and drop location

Monitor the temperature rise on the back of the material

Evaluate the high-temperature protection level of the material under molten metal droplet impact

Its test results determine the safety rating of protective clothing and are an indispensable key link in the labor protection system of high-temperature industries.

II. Compliance with Multiple National and International Standards

The GT-C94 Splashes Impct Resistance Tester is developed and manufactured strictly in accordance with the following standards:

AQ 6103-2007
GB/T 17599
GB/T 8965.2-2009
ISO 9150
EN 348

These standards specify requirements for molten metal droplet generation method, droplet quantity, droplet weight, temperature measurement method, back temperature rise limitation, etc.

Through standardized structural design and program-controlled operation, the Splashes Impct Resistance Tester ensures consistency and high repeatability of the testing process, making it widely applicable to protective clothing manufacturers, third-party testing agencies, research institutions, and other units.

III. Generate Metal Drop Device

One of the core components of the GT-C94 molten metal splash tester is the molten metal droplet generation device. This system can steadily and continuously produce molten metal droplets that meet the requirements of the standards.
