1.Limiting Oxygen Index Apparatus This test method describes a procedure for

measuring the minimum concentration of oxygen in a flowing mixture of oxygen and nitrogen that will just support flaming combustion. Test applicable for wide range of materials such as Polymers, Cables, Textiles, Rubber etc. Supplied as per requirement, FTA or HFTA mode. For oxygen and nitrogen measurement in addition to Rotameter, direct oxygen percentage can be indicated digitally in the oxygen and nitrogen mixture, with the help of Oxygen Meter.

For HFTA mode a Heater, Temp. Controller and Sensor is provided.

2. Smoke Density ApparatusDensity of smoke from the burning or Decomposition of plastics is measured.This test method describes the measuring and observing the relative amounts of smoke obscuration produced by the burning or decomposition of plastics. It is intended to be used for measuring the smoke producing characteristics of plastics under controlled conditions of combustion or decomposition. The measurements are made interns of the loss of light transmission through a collected volume of smoke produced under controlled, standardized conditions.Digital Electronic Photometer with a 0 to 100 % Absorbance Scale & Electronic Timer Provided
