Theoven is designed to give 8 to 20 air changes per hour.

An air flow meter (Rota meter) is fitted to control and monitor the airflow rate.Range 0- 10 LPM, LC-0.5 LPM

Grips are provided at the top of the oven to hang specimen/s.

Suitable weights up to 1 kg are provided with provision to attach theweights to one end of the test pieces.

Two Stainless Steel Scales are provided for elongation measurement

A blade is provided in the oven to cut the sample to remove the tensile force without opening the door.

The sample is hanged using the grips inside the Hot Set Oven along with the weights for 15 mins. The sample starts to elongate due to heat. The elongation of the sample is measured using Dial Gauges. The sample is then cut to evaluate the permanent set.

The test requirement is 8 to 20 air changes per hour, measured on a Flow Meter. According to IS standard, if the Oven does not have a regulated air supply, the oven is then termed as a Hot Air Oven and not a Hot Air Oven (as offered by some manufactures) and cannot be used for this kind of test

Also if normal oven is used for the test, the operator will have to open the front door to hang the samples, resulting in loss of temperature. As the test is only 15 mins, it will not be possible to regain the temperature. In our Hot Set oven, we use an especially designed Top Hanger which can be hanged from the top of the Hot Set Oven, without opening the front door. To achieve minimum loss of temperature, we provide two hanger assemblies. One is used as dummy that is used for achieving the desired temperature. In the meanwhile operator can assemble the sample, weights etc on the other hanger, which can be then put in the oven, just be replacing the dummy into the oven. This way the loss in temperature is not more than few degrees.

• Air source to provide 8-20 air changes per hour, a compressor compressed air line of 4 to 10 liters min. is required. If this facility is not already available, a suitable air compressor may be purchased from us.
• Sample Conditioning: The test specimens are required to be kept at a temperature of 27 2 deg C for a period of 16 hours, immediately before the test. If the conditioning chamber is not available with you, the same can be purchased from us.

this test instrument is designed to covers a laboratory procedure for testing of bunch cables mounted vertically to determine their relative ability to resist flame prorogation. The objective of the fire test is be to approximately simulate the installation condition and provide consistent results.

the propagation of flame along a bunch of cables depends on a number of feature, such as:

• the volume of non-metallic material exposed to the fire and to any flame which may beproduced by the combustion of the cables;
• the geometrical configuration of the cables and their relationship to any enclosure;
• the temperature at which it is possible to ignite gases emitted from the cables;
• the quality of combustible gas released from the cables for a given temperature rise;
• the volume of air passing through the cable installation and
• the construction of the cable, for example armored or unarmored.

all of the foregoing assume that the cables are able to be ignited when involved in an external fire.

the fire test should demonstrate that the bunched cables do not propagate fire even if its outer covering and insulation have been destroyed in the area of flame impingement.

Smoke Density Apparatus is used for measuring & observing the relative amount (Density) of smoke produced by the burning (combustion) or decomposition of Plastic, Cables etc. under controlled conditions.

Smoke Density Apparatus is used for measuring & observing the relative amount (Density) of smoke produced by the burning (combustion) or decomposition of Plastic, Cables etc. under controlled conditions.

The sample is burned under controlled pressure of LPG, through a specified burner as per the standard. A light source and a photo receptor is placed on either side of the chamber, and the percentage of light absorbed is displayed through a linear amplifier digital electronic photometer with 0 to 100% absorbance / Transmission / lux scale. The apparatus comes complete with timer , gas pressure gauge, damper and exhaust fan for removing smoke from the chamber.

The Sample is burned using ASTM specified burner under control conditions. A Light source (6 V DC Bulb) emits light which is captured by Photocell which converts the light into Voltage. The intensity of light is proportional to the voltage produced. This voltage is picked up by sophisticated electronic detector, which display the same as % Absorption. As the smoke fills the chamber, the light intensity is reduced, reducing the voltage and the % absorption increase.

The instrument is controlled using a PLC. All the parameters including burner movement, timer, recording of absorption % etc are controlled using the PLC. The parameters are displayed on a 7 touch screen HMI. The user can interacts with the instrument using this HMI.Operator and test parameters are feed in the PLC using the HMI only. The results are displayed on the HMI screen. The screen shots can be stored on the pen drive for future references.

For certain locations it may be important to use a cable which retards flame in case of fire and is self extinguishing when the source of fire is removed. This test is carried out on finished cables to verify this property.

For certain locations it may be important to use a cable which retards flame in case of fire and is self extinguishing when the source of fire is removed. This test is carried out on finished cables to verify this property. The sample cable is hanged in the chamber and is burned through the burner provided in the instrument for the prescribed time. After the flame is removed, the period of burning of cable is noted by a stop watch. After the cable ceases to burn, the effected area is measured through the scales provided in the chamber.

The instrument conforms to IEC: 60332 Pt 1 & 2 and IS: 10810 Pt 53

The instrument consists of

.

Inner chamber of 1200 x 300 x 450 mm made of Stainless Steel
