SMOKE DENSITY TEST APPARATUS ASTM D- 2843

E.S.C.R. Apparatus

Density of smoke from the burning or Decomposition of plastics (As par ASTM D-2843) This test method describe 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 plastic 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.

a) Air Oven of size 450x 450x 450mm is generally used to find out the loss of mass of the polymeric material kept inside the oven for a certain period of time at a temp. of 200 degree centigrade.( As per IS 10810 part 10) Max. Temp. 250 degree centigrade

b) For Part 11 preferably a multicell ageing oven is used having different cells of size 100mm Dia. And 300mm Length with a provision to replace air for 8 to 20 times per hour. Each cell will have individual temp. control, Hour meter, PT 100 Sensor and provision to hang the samples.Each cell can be maintained at different temp. Max. temp. 200 degree centigrade.


THERMAL STABILITY TEST APPARATUS as per IS 10810 – Part 60

The instrument has an alumiium block maintained at a temp. of 200 degree centigrade and polymeric sample is kept in a test tube is heated for a certain sspecified time. The smple is then evaluated for its thermal properties.

HOT SET TEST OVEN AS PER IS 10810 PART – 30

It is an oven with an arrangement to hang the dumbbell shaped sample inside the oven with a set of weights which can be hanged at one end of the sample. Pointers are provided on the gauge marks on the sample and elongation of gauge length in 20 minutes is measured with the help of a scale fixed inside the oven just near to the sample. In side of the oven is provide with a bulb to view the sample from the front glass door. Max. Temp. 200 degree centigrade.size of 400x 380x 200mm


Accessories for carrying out heat shock test as per IS 10810 PART 14 AND Hot deformation test as part 15. Both these tests are carried out inside an air circulating oven.

Heat shock test The test is performed to find out cracking of thermoplastic insulation and sheath of cables on overheating. The test specifies the heat treatment given to the thermoplastic insulation and sheath at accelerated temperature and duration to ascertain the withstand ability at that condition. It is only a visual examination. The specimen is wound over a smooth round shaped mandrel for three turns in a close helix and then the mandrel is kept in an oven at a specified temp. and for the duration specified. At the end of this period the samples are cooled in air for one hour .The test specimen is then examined for any cracks visible to naked eye.

Hot Deformation Test The thermoplastic compound tends to soften when maintained at high temperatures. If thay are subjected to mechanical pressure, the physical dimension change take place .The specimen is kept in an oven with an arrangement to exert pressure on the test specimen. The oven is maintained at the required temp. The duration of the test is as per the specifications mentioned by the user. Immediately after cooling, the indetation on the sample is measured with the help of graduated microscope or with graduated magnifying glass. The thickness retained at the point of impression expressed as a percentage of the initial thickness denotes the degree of resistance of the material to hot deformation.
