ISO 9150 Small Splashes of Molten Metal Drop Impact Testing EN 348 Fire Resistance Apparatus

ISO 9150 Small Splashes of Molten Metal Drop Impact Testing EN 348 Fire Resistance Apparatus

Introduction:

    The molten metal drop impact tester is developed according to the EN 348 and ISO 9150 test standards, and also meets the requirements of the domestic GB8965.2-2009 "Welding protective clothing" and GB/T 17599-1998 "Determination of molten metal impact resistance" test standards. The test principle is to use a welding gun to melt the welding wire, and when the dripping material causes the temperature of the calorimeter on the back of the fabric to rise by 40°C, the number of molten metal drops that fall is measured.

Scope of application:

1. 1. Applicable to the heat protection performance of protective clothing fabrics and composite fabrics impacted by metal droplets.
   

2. 2. When the metal droplets impact the sample at a certain angle, the number of droplets required for the sensor behind the sample to rise by 40°C is measured.

3. 3. The metal splash impact performance tester uses a burner to melt the welding wire, and when the droplets cause the temperature of the calorimeter on the back of the fabric to rise by 40°C, the number of molten metal droplets that fall is measured. Thus, the heat protection performance of the fabric impacted by metal droplets is measured.

Main feature:

• 1. The molten metal drop impact performance tester includes a burner, a sample frame, a welding strip drive device, a burner flow controller, a human-machine interface display device, etc.;

• 2. The oxyacetylene welding torch is used to melt the metal strip, and the welding nozzle diameter is (1.2±0.1) mm;

• 3. A stepper motor is used to drive the metal strip, and the running speed of the metal strip can be set;

• 4. The molten drop guide mechanism is coated with a high-temperature anti-sticking guide groove with an angle of 45 degrees;

• 5. The fabric temperature sensor device is used to measure the temperature rise on the back of the sample;

• 6. The counterweight copper hammer device is used to set the fabric pre-tension of 175g±0.5g;

• 7. The temperature rise data can be automatically recorded, and the number of molten drops is recorded by the tester.
