EN ISO 1182 Building Materials Non Combustibility Test Apparatus

EN ISO 1182 Building Materials Non Combustibility Test Apparatus -  Scope of application

This test method for evaluating the combustion performance of building materials under laboratory conditions. For composite products, each component material of the product can be tested separately and explained in the test report. This test is related to the A1, A2, A1f1, and A2 f1 ratings in the building product classification.

EN ISO 1182 Building Materials Non Combustibility Test Apparatus - Test method

The sample is placed in the furnace, the thermocouple is inserted into the center of the sample, and the test equipment is connected. The exposure temperature is 750°C and the test time is 20 minutes. The thermocouple temperature and burning time are recorded during the test.

EN ISO 1182 Building Materials Non Combustibility Test Apparatus - result evaluation

According to EN1182, the "combustibility" or "non-combustibility" of materials is evaluated according to the following provisions:

The average temperature rise in the furnace should not exceed 50°C, and the calculated average duration of the flame should not exceed 20S

After cooling, the average mass loss should not exceed 50% of the average initial mass

Introduction:

Non-combustible material refers to a material that is heated by fire even in the event of fire, even if it is burned red or melted. The non-combustibility tester is developed according to ISO 1182 and GB/T 5464 non-combustibility test method for building materials. Main application The non-combustibility test method for building materials is suitable for testing the burning performance classification of Class A fireproof materials in the burning performance classification of building materials GB 8624. The non-combustible test furnace can be applied to composite products as well as to the materials of the components constituting the product. The non-combustibility tester can also be applied to the fire test of British building materials, railway locomotive materials and non-metal products. The non-combustibility tester test data includes the temperature rise in the furnace, the thermal weight loss of the test sample, and the ignition time of the sample.

Features:

• High degree of automation, test procedure is safe and reliable, easy to operate.
• Temperature control: 750℃±2℃; resolution: 0.1℃.
• 750±5℃ temperature is automatically controlled by a PID and a Power controller.
• Equipped with 3 thermocouples, for temperature in the furnace, the specimen center, and the specimen surface, respectively.
• An inner furnace thermocouple device to calibrate the temperature of the furnace. At the same time, in the computer software, the average value of each point can be calculated to obtain a standard temperature curve.
• 360-degree rotatable and height-adjustable thermocouple scanning device.
• The test software controls the furnace temperature in stages so that the radiant furnace has a longer 
• test life.
• 7” touch screen for control parameter setting and display / tested acquisition and preservation/screen monitoring / real-time temperature curve shows / historical curve and data query.
• To be equipped with a printer, to print the temperature curve.
• Testing results include Mass Loss(g) and Rate(%), Ignition Time(s) and Sustained Flaming(s), Initial & Maximum Furnace Temperature(℃), Final Furnace Temperature(℃), Maximum Specimen Center Temperature(℃), Final Specimen Center Temperature(℃), Furnace Temperature Rise(℃), Specimen Center & Surface Temperature Rise(℃).
