Cord guard Flexing test designed as per IS: 302, IS:366, IS:1293 and all the international standards

How Test is Performed ?

For guards which do not comply with the dimensional requirement of this clause, a sample of the guard, together with the cable or cord delivered with the appliance, is to be subjected to 5000 cycles of flexing. The guard is mounted in the appliance with 60cm to 100cm length of cord. With the appliance held stationary, the guard is flexed by moving the cord back and forth in a plane through an angle of approximately 90 degree and 180 degree. At the end of the test, The guard and the cord shall slow no unusual signs of abrasion or wear.

Salient Features

• With standard weights
• With 6 digit preset counter

It is used to test insulation materials used in Electrical wiring accessories, Electrical Appliances, luminaries, motors, connectors and non metallic components which are subjected for operating at above room temperature etc.

The test ensures that external parts of insulating material, the deterioration of which might cause the appliance to fail to comply with the relevant standards, are sufficiently resistant to heat.

How Test is Performed ?

Enclosures & other external parts of insulating material are subjected to the test. The ball pressure apparatus is designed to verify the quality & safety characteristics of products, as required by national & international standards. The sample to be tested is placed on a platform & the ball pressure apparatus is placed on top of it. The whole assembly is then placed inside an oven & maintained at the test temperature for the specified time period. After the test period, the sample & ball pressure apparatus are removed from the oven & cooled to room temperature. Finally, the depression created by the ball pressure apparatus in the sample due to softening of the sample is measured. The sample is said to comply with the requirements if the diameter of the impression does not exceed the value specified in the respective specifications.

Specifications

• Test to determine resistance to heat in insulating materials.
• To check insulating materials used in electrical appliances, Luminaries & accessories.
• The apparatus checks the deterioration in insulation which might reduce the safety of the appliance.
• All stainless steel construction.

Endurance Test For Thermostat equipment specially designed to test life cycle of thermostat as per Indian and International standards.Used for Storage Water Heater (Geysers), Refrigerators and general purpose ThermostatsThe device consists of Digital voltmeter, Digital Amp. Meter Load as per requirement Temperature controller and safety devices.The thermostat is heated & cooled by TEC (Gas free) based system without the use of Compressor and Gas .The system is programmable to conduct maximum 30 cycles per hour and is also protected against the failure of thermostat.A unique Programmable Logic Controller is specially designed for presetting number of cycles, automated conditioning of Thermostat, Logging, Drain and various modes of operations pumps and solenoids control. There are also override controllers for conditioning bath temperature control.

With latest technology up-gradation we have also developed this device with fully programmable logically controlled.

This apparatus is designed to meet the test standards UL, BAEV and IS to check Cut IN and Cut OUT characteristics of bi-metal type thermostatsThe test bath consist of following :-

> Continuously variable temperature WaterOil bath. > PID featured temperature profiler to maintain temperature curve > Audio visual indication for Cut IN and Cut OFF of the thermostats

If required we can also provide Data Logger to record the temperature readings of the thermostats.
