Customer Reviews
We have received all the instruments, and will test them, for the moment we have very good feelings. Thank you.

—— Mr.Brett Cirulis

I really would like to work with YUYANG, their professional service on the laboratory solution and reliable products help me win much market!

—— Mr. Allan Ken

Nice cooperation! We appreciated for your company's kind support on our projects. Very good service.

—— Mr. Jaleshwar Prasad

I was set up your machine one week ago. İt’s good working. Thank you for all.

—— Ms.Erdem Traina

Quality is your factory culture, Quickly response is your core! Keep it and let YUYANG brand testing machine around the world.

—— Mr. Komarov Mihail

There are seldom suppliers willing to do small spare parts for us, while YUYANG spends time with us, only for three burners, we appreciate them.

NES 713 Smoke Density Apparatus

50l/S Low-Smoke Vacuum Cleaners Smoke Toxicity Index Test Chamber

 

Description:

This tester measures the Toxicity Index by ppm in Naval Engineering Standard chamber when

complete combustion occurs by burner.

NES 713 TOXIC Chamber meets the standard of NES 713 and is used to measure combustion

characteristics about materials.

NES 713 Toxic Chamber measures Toxicity Index after perfect combustion by burning 100g of

specimen.

 

Standard:

NES 713: Determination Of the Toxicity Index Of the Products of Combustion From Small

Specimen of Materials

JB/T 10707: Low-Smoke Halogen-free Thermoplastic Compounds for Flame Retardant Cables

 

Feature:

1. Observation window made in reinforced plastic allows easy observation of combustion

conditions during the test

2. Treating the inside of Chamber with Teflon Coating minimizes chemical reaction with gaseous

materials generated in combustion.

3. Door locking device designed for easy opening/closing.

4. Specimen Support for Burner to be located in the center of the combustion mass and for test

specimen to be easily loaded

5. Designed for testing in Auto/Manual Mode

6. Auto Ignition for controlling ignition and extinguishment of Gas Burner by Time Device

7. Auto Vent Mode allowing auto release of combustion gases generated in combustion by Time

Device

8. Auto Stirrer Mode for complying with conditions of combustion gas stirrer by Time Device

specified in the standard Time Device

 

Application:

The NES 713 test explores the toxicity of the products of combustion in terms of small molecular

species arising when a sample of a material is completely burnt in excess air under specified

conditions. The test does not necessarily determine the total toxicity of all the constituents of the

products of combustion.

The test is useful for the quality control of materials and for research and development. It may be

used to compare the particular combustion characteristic of a series of both natural and synthetic

materials. The test may be used to specify a quality of a raw material or product. Combustion

characteristics tests alone are not suitable for assessing the total fire hazard of products under

actual fire conditions.

The toxicity index is defined as the numerical summation of the toxicity factor of selected gases

produced by complete combustion of the material in air under the conditions specified. The

toxicity factors are derived from the calculated quantity of each gas that would be produced

when 100g of the material is burnt in air in a volume

Test Result:

If 100g of material is burned and the material is diluted in the air of chamber, concentration of

each generated gas is given by the following equation.

C × 100 ×V

C8 = --------------- (ppm)

m

C = concentration of gas in test chamber (ppm)

m = fire test mass (g)

V = volume of test chamber (m3)

1, 2, 3, ... indicates each found Gas.

Cf = concentration of the gas considered fatal to man for a 30 minute exposure time(ppm)
