Introduction:
Non-combustibility The non-combustibility and combustibility of uniform and non-uniform construction materials of actual elements are measured by the tester. The evaluations (results) are growing furnace temperatures, fundamental mass loss, and specimen igniting. It completely complies with GB/T 5464 and ISO 1182 international standards. This testing equipment employs a module type temperature controller to remain stable at the furnace setting of 7505°C for 60 minutes and get precise test results. Another benefit is the automatic up-down specimen moving system, which ensures correct results, as well as the simple method.
Application:
* Building Materials
* Rail
* IMO
Standards:
ISO 1182
- Reaction to fire test for building material---Non-combustibility test
Test procedure:
1、Test environment
The apparatus shall not be exposed to draughts, any form of strong direct sunlight or artificial illumination which would adversely affect the observation of flaming inside the furnace. Surrounding areas should be prepared in such a way that they do not interfere with the observation. The room temperature shall not change by more than 5。C during a test.
2、Set-up procedure
（1） Specimen holder
Remove the specimen holder and its support from the furnace.
（2） Thermocouple
Position the two furnace thermocouples as specified place， and position additional thermocouples, if required, as specified and Annex C. Connect all thermocouples to the temperature indicator using compensating cables.
（3） Electricity supply
Connect the heating element of the furnace either to the voltage stabilizer, variable transformer and the electrical input monitor or the power controller. Automatic thermostatic control of the furnace shall not be used during testing.
The heating element normally draws a current of between 9 A and 10 A at approximately 100 V under steady state conditions. In order not to overload the winding, it is recommended that the maximum current not exceed 11 A. It is recommended that a new furnace tube be subjected to slow heating initially. A suitable procedure has been found to increase the furnace temperature in steps of approximately 200 °C, allowing 2 h heating at each temperature.

- Fire Tests on Building Materials and Structures.. Part 4: Non-Combustibility Test for Materials
BS 476-11
- Fire tests on building materials and structures - Part 11: Method for assessing the heat emission from building materials.
Test procedure:
The test shall be carried out in the furnace described. The furnace temperature shall be measured by the thermocouple, positioned so that its hot junction is 10 mm from the wall of the furnace and at mid-height of the specimen. A second thermocouple shall be placed in the centre of the specimen, inserted from the top through a 2 mm diameter hole drilled, where necessary, for this purpose. This shielded thermocouple shall maintain contact with the material at the bottom.
The furnace shall be heated and its temperature stabilized at 750士10 °C for a minimum period of 10 min. The specimen shall then be inserted in the furnace, the whole operation being performed in not more than 5 s. A record shall be made for a further 20 min of the temperature of the two thermocouples by means of a continuous recorder; the occurrence and duration of any flaming in the furnace shall be noted. The stabilized heating current shall be maintained unchanged for the period of the test.

Calibration Test Report before Leaving the Factory:
Before shipment, the ISO 1182 non-combustibility tester will be calibrated and tested. It is used to test the temperature of the furnace wall, the temperature in the furnace, and the normal operation of different basic operations. We ensure that our ISO 1182 Non-combustibility tester is fully trouble-free and that the test results are highly consistent. Along with the equipment, the customer will receive the calibration test report for the non-combustibility tester.
