Product Description:-

Specific parameters are as follows:

Light source: imported German incandescent lamp

Nominal voltage: 6V

Accuracy: ±0.01V

Receiver: For the Hamamatsu Silicon Photovoltaic Cell of Japan, the signal is amplified by the board and input to the computer through the I/O board. The spectral response is matched with the photometer of the International Commissioner of Light (CIE).

Laser system: The laser photometer should use a helium-neon laser with an output power of 0.5 mW to 2.0 mW. Air should be introduced into the tube, and the optics should maintain the cleanliness (F.4.2) that meets the requirements for light attenuation drift. Compressed air can be used instead of self-inhaled air.

2. Analytical instrument pre-treatment: Before the analysis of the oxygen and carbon dioxide content of the flue gas generated during the test, pre-treatment is carried out to ensure the flue gas is dry and the particle concentration level required by the analytical instrument is reached. The pre-treatment consists of condensation, filters, German KNF sampling pumps, flow meters and piping.

Frequently Asked Questions:-

What is EN 50399?

EN 50399 specifies the apparatus and methods of test for the assessment of vertical flame spread, heat release, smoke production and occurrence of flaming droplets/particles of vertically-mounted bunched wires or cables, electrical or optical, under defined conditions.

What is the difference between sanity and smoke testing?

Smoke testing is a subset of acceptance testing whereas Sanity testing is a subset of Regression Testing. Smoke testing is documented or scripted whereas Sanity testing isn’t. Smoke testing verifies the entire system from end to end whereas Sanity Testing verifies only a particular component.
