Introduction

Measures Toxicity Index inside the Chamber with unit ppm when complete burning occurs by burner.

It is an equipment that exactly meets the international standards of NES 713 and is used to determine the combustion characteristics of the burned material.

It measures the toxicity index of the chamber with unit ppm when complete burning occurs by a burner with a certain volume and proper radiant heat condition under the condition of small and flat specimen of material (100g) 

 

▣ NES 713: Determination Of The Toxicity Index Of The Products Of Combustion

From Small Specimens Of Materials

▣ Easy to observe combustion condition during test through observation window made of reinforced plastic

▣ Teflon coating treatment inside the chamber minimizes the chemical reaction with the gaseous substances generated during combustion

▣ Door lock designed for easy opening and closing

▣ Burner is located at the center of burning volume. Specimen support for easy loading test specimen

▣ Made to test with Auto / Manual mode

▣ Auto Ignition that can control ignition and extinguishment of gas burner by time device

▣ Auto Vent Mode that enables automatic discharge of combustion gas generated by combustion by time device

▣ Auto Stirrer Mode that satisfies combustion gas stirrer conditions specified by the standard by time device

▣ Automatic Vacuum Pump for Sampling of Combustion Gas (Sampling processes automatically according to the set number of times)

When 100 g of substance is burned and the combustion substance is diluted in the air in the chamber,

The concentration of each gas generated is calculated using 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)   

Toxic Index 

 

1, 2, 3, ... Represents each Gases founded.

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