IEC 61034-2 Smoke Density Test Apparatus

Product Description

The 3 Metre Cube Smoke Density Apparatus, in accordance with IEC 61034 or BS 6853, provides a test method for measuring the density of smoke generated from building material or cable burning under a defined fire source.

During the test, when smoke is generated, the optical transmittance is continuously changed by blocking the light path through the smoke, resulting in a minimum transmission value and a test time to reach the minimum transmission

Standards

IEC 61034- 1 & 2: Smoke density test of cable burning under specific conditions

part 1: test device- part 2: test process and requirements

BS 6853: General specification for fire protection in the design and construction of passenger trains

Technical Parameters

1.The box body is composed of a cubic shell of 3000mm±30mm. The internal material of the box body is: SUS 304 stainless steel, filled with calcium silicate fireproof material, and the outside is made of iron material and sprayed with plastic;
2.Equipped with wire and cable test rack and hanging weights according to standard requirements.
3.The door of the test box has its own glass observation windows on the opposite sides, with sealed and transparent windows (minimum 100mmx100mm) installed to transmit the light of the horizontal optical measurement system.
4.Photocells and light sources are placed in the center of each window on both walls without physical contact
5.Lamps are configured to provide a certain level of light.

6.Photocells can test the weakening of light caused by smoke

7.Smoke density test photocell and dust-proof protective tube, the output impedance is less than 100Ω.
