Building Materials Non-Combustibility Test Furnace

The Building Materials Non-Combustibility Test Furnace is designed to evaluate the non-combustibility performance of building materials under controlled laboratory conditions. The ZNJCB-2 model uses a heated furnace tube and multiple thermocouples to monitor furnace temperature, specimen center temperature, and specimen surface temperature during testing.

Equipped with a temperature control system and dedicated testing software, the furnace automatically controls the heating process and manages temperature in stages. It is intended for building material manufacturers, fire testing laboratories, and quality inspection institutions evaluating the reaction-to-fire performance of building materials.

Applicable standards:

GB/T5464-2010 GB/T8624ISO1182 Fire reaction test for building products -- non-combustible test

Scope of application:

ZNJCB-2 building materials incombustible test furnace according to the national standard

Developed according to the technical indicators and requirements specified in GB/ T5644-2010, and applicable to the test method for evaluating the combustion performance of building materials under laboratory conditions. It is suitable for testing the combustion performance classification of Grade A fireproof materials in the combustion performance classification of building materials GB8624.

Technical parameters:

1. The inner diameter of the furnace tube of the heating furnace is 75mm+1mm, the outer diameter is 90mm±1mm, the height is 150mmt1mm, and the power is about 2KW

2, install the thermocouple in the furnace, sample center thermocouple, sample surface thermocouple,

3. Thermocouple scanning device that can be rotated and lifted 360 degrees

4, stainless steel inverted cone air flow stabilizer and cylinder fairing,

5, the software automatically controls the heating rate, and controls the furnace temperature in stages.

Features:

(1) Controlled Furnace Heating: The software automatically controls the heating rate and regulates furnace temperature in stages.

(2) Multi-Point Temperature Monitoring: Thermocouples monitor furnace temperature, specimen center temperature, and specimen surface temperature.

(3) Adjustable Thermocouple Scanning: The scanning device supports rotation and height adjustment to accommodate the required measurement positions.

(4) Furnace Tube Design: The furnace tube is manufactured to the specified inner diameter, outer diameter, and height tolerances.

(5) Airflow Stabilization: A stainless steel inverted-cone airflow stabilizer and cylindrical fairing are provided to support the intended furnace airflow arrangement.

(6) Automatic Temperature Management: Software-based control reduces the need for continuous manual temperature adjustment during the prescribed heating process.

(7) Laboratory Testing Application: Designed for non-combustibility testing of suitable building materials under specified laboratory conditions.
