It shall replace GB/T12666.6-1990 "Test Methods for Burning of wires and Cables - Part 6: Test methods for fire resistance characteristics of wires and cables" as of the date of implementation. Iii. Equipment Features
1. It adopts imported rotameters, blowtorches and Venturi mixers, ensuring precise flow control, stable and uniform flames, and consistent temperature
Good consistency;
2. Imported thermometers and thermocouples, with a temperature measurement error of no more than 1%.
3. The equipment is equipped with leakage, overcurrent and overvoltage protection devices. In case of a fault, it will automatically cut off the high-voltage source to ensure the safety of the equipment and operation
Personnel safety;
4. The equipment is equipped with an airflow barrier inside to ensure that the shape of the flame is not affected by the airflow.
5. The equipment is equipped with excellent exhaust and waste gas treatment devices, ensuring that the test exhaust gas will not pollute the laboratory environment.
6. All the equipment is made of 304 stainless steel, which is aesthetically pleasing and will not rust even after long-term use.
Iv. Equipment Composition
1. Design of the combustion chamber (see Figure 1
The entire cubic combustion chamber is formed by fixing double-layer SUS304 stainless steel materials on the stainless steel square tube bracket. The space between the inner and outer partitions of the combustion chamber is filled with insulation cotton. The dimensions of the combustion chamber are 3Mx3Mx3M, totaling 27 cubic meters.
2. Sample support: The sample is supported by two or three metal rings with an inner diameter of approximately 150mm, as shown in Figure 2
V. Main Technical Parameters

1. Blowtorch: It is a propane gas blowtorch with a nozzle nominal length of 500mm and a width of 15mm, equipped with a Venturi mixer. The nozzle has three rows of staggered drill holes with a nominal diameter of 1.32mm and a center distance of 3.2mm. See Figure 3;
2. Flowmeters: Rotameter (Air) : 100L/min, rotameter (propane) : 10L/min;
3. Gas pressure gauges: Air 0-0.6MPa, gas 0-0.25MPa;
4. Components of the blowtorch control system: pressure regulating valve, piezoelectric igniter, flameout device, thermometer, K-type thermocouple, gas source (provided by the customer), regulating valve, ignition device, gas pipeline, flowmeter, Venturi mixer, blowtorch, ball valve, air pipeline, compressed air (provided by the customer).
5. Timer: 0 to 99.99s/m/h can be set arbitrarily;
6. Ignition device: Automatic piezoelectric ignition;
7. Temperature controller: It has two K-type thermocouple measurement inputs, with a temperature range of 0 to 1200℃ that can be set arbitrarily.
(2) Line Load control Section: (As shown in Figure 4
Test transformer: One 8KVA capacity, three-phase 1000V output AC transformer;
Voltage regulator: Capacity 8KVA, input 380V, output adjustable from 0 to 400V;
Test voltage: Continuously adjustable from 100 to AC1000V;
Voltage and current display: Voltmeter display range: 0-2000V, ammeter display range: 0-5A.
Test current: Maximum 3A;
1- Transformer 2- Fuse (2A) L1, L2, L3 3- Connect to L3 (or L1 or L2) phase N
4- Support ring 5- Test conductor 6- Load and indication device (such as bulb) 7- Sample 8- Metal shielding
(3) Exhaust gas treatment device: The exhaust gas treatment adopts a spray-type gas absorption tower to absorb the smoke dust and harmful gases produced during combustion
The body can be shared with the bundled cable combustion testing machine or other combustion machines.
