Flame Propagation Test (Single)

General Information  

Test of the fire behavior on a single core or a single cable, Flame retardant.
(IEC 60332-1)

Time for flame application:

The wire or cable shall pass the test, if the distance between the lower edge of the top support and the onset of charring is greater than 50 mm. All soot is to be ignored. Softening or the non-metallic is also to be ignored. 

Kind of test using the equipment: 

- Flame Spread test on Single Cables. (IEC 60332-1) 

Technical specifications  

- Shape sizes: 730 x 700 x 2650 mm 

- Effective size of chamber: 300±25 × 450±25 × 1200±25 mm 

- The nominal power of burner: 1 kW 

- The gas supply for burner, propane gas or petroleum gas. 

- Flow regulate scope of propane gas: 0 ~ 700 ml/min

- Regulate scope of compressed air: 0-11 L/min

Flame Propagation Test (Bunched)

General Information  

Samples / Time for flame application:  

No. of the samples (each3.5 m long) is Calculated as follows:  

• Cat. A: 7 l/m, Time > 40 min.  

• Cat. B: 3.5 l/m, Time > 40 min.  

• Cat. C: 1.5 l/m, Time > 20 m in.  

(Total volume of non-metal material in ...liter / meter)  

The cable shall pass the test, if the created flames are self extinguishing and the maximum extent of the charred portion measured on the sample shall not have reached a height exceeding 2.5 m above the bottom edge of the burner. All soot is to be ignored if, when wiped off, the original surface is undamaged. Softening or any deformation of the non metallic is also to be ignored.  

Kind of test using the equipment:  

- Test of the fire behavior on bunched cables, reduced flame propagation.  

(IEC 60332-3, cat. A, B or C)  

Technical specifications  

- The chamber for bunched burning with auto lifting and dropping ladders device.  

- The control cabinet with twice gas supply system, monitoring for chamber
   temperature and time control.  

- A set of dedusting and exhaust fume system with 4 layer filtering.  

- Two normative ribbon burner installed on dolly (with Venturi mixer)  

- Two burning ladder (one normative ladder and one wider ladder)

- A set of anemometer for measuring air flow in chamber. The air anemometer used
  in discharge inside the body of a set of box constitutes

Oxygen Index

General Information  

Measuring the minimum oxygen concentration to support candle-like combustion of plastics.

The oxygen index describes the minimum concentration of oxygen, expressed as volume percentage, in a mixture of oxygen and nitrogen that will just support combustion of a material / plastic / compound initially at room temperature under specified test conditions.   
Kind of test using the equipment:  

- Oxygen Index Test. (ISO 4589-2)  

Technical specifications  

- Shape size of the control cabinet: 520 x 300 x 700 mm  

- Shape size of burning cylinder: 250 x 250 x 550 mm  

- Regulate scope of flow meter :  

  - Oxygen flow meter, 0.04~0.4 m³/h

  - Nitrogen flow meter, 0.16~1.6 m³/h
