IEC 61034 Smoke Density Test Apparatus Cable Flammability Tester

 

Introduction:

The main principle of smoke density measurement is that in a specific space, the cable or material produces smoke under a specific burning or radiation condition, and the light beam will decay after passing through the smoke. The light transmittance of the beam is measured and the specific light density and smoke density are calculated.

The wire and cable smoke density tester conforms to GB/T17651.1~2-1998, iec61034-1 ~ 2:1997 "determination of smoke density of cables and optical cables burning under certain conditions", which is used to measure the transmittance of smoke released by insulated metallic conductor cables or optical cables when they are burned horizontally under certain conditions.

Standard:

IEC 61034 - 1 & 2

- Measurement of Smoke density of cables burning under defined condition

- part 1 : Test apparatus

- part 2 : Test procedure and requirements

BS 6853

- Code of practice for fire precautions in design and construction of passenger carrying trains

Feature:

1. Chamber internal area is 3000mm±30mm and it's structured as Cubic Enclosure with appropriate fixed iron frame angle;

2. It's configured with a door with test glass windows and in both faces of the opposite side there's a sealed transparent window (minimum 100mmX100mm) with a horizontal light measure system that allows light penetration;

3. Designed to prevent direct sunlight exposure and severe weather change in Enclosure;

4. Photocell and Light Source are located in the middle part of both windows of the wall surface in the opposite side to avoid physical contact;

5. A lamp to provide regular light is installed;

6. Two types of auto Filter system (Carrusel) are installed to automatically calibrate the transmissivity of light;

7. The reduction of light by smoke is measured using Photocell;

8. In order to verify accordingly the intensity of radiation to measure light change by self-emission, the IEC 61034 Smoke Density Tester for Wire has been designed to fit various kind of filter in the Light Source;  

9. Support system to allow separate fitting of Light Source and Photocell in the outer wall;

10. The Light Source is a halogen lamp with a clean crystal lamp and tungsten filament;

11. Average power : 100W, Average voltage: DC12v, Average velocity of light : 2000 lm~3000 lm, and Average color temperature : 2800K~3200K;

12. The Receptor Photocell is selenium or silicone type and has a spectrum reaction conform to Photopic Observer (similar to a human eye) of the International Commission on Illumination (CIE);

13. A heating system is installed within the cube to swiftly match the standard temperature (25ºC±5ºC) in the initial test;

14. We seek tester's safety and convenience through an Auto ignition system.

Test Result:

- Flameout time(min)

- Time to max Ao

- Min light transmittance (%)

- Add photo feature of carbonization area
