This tester is used to test the water resistance of the material such as enameled copper wire, insulating sheath...etc.
Within a certain period of time, the specimen is being soaked in the hot water in order to study the degenerating condition such as blistering, fading, swelling, etc. In addition, the test method is expected to further calculate the changes in weight while under such as condition.

CNS 687,689,3985,3986,3987
This machine is used for testing the enameled copper wire, insulator or sheath that are made of rubber or plastic. Soak sample in warm oil after a given period of time and then take out specimen for testing its residual rate of tensile. If the sample happened to be enameled wire, you can detect the quality of its varnish film.

JIS K6545, ASTM-D1790, D1593
This tester is used to test the cold resistance for the materials of rubber, plastic, cable sheath, outsole, whole shoe leather and synthetic leather, in order to understand the feathers of those materials under a freezing circumstance. This tester would be excellent equipment for quality improvement. Inside the chamber there are many selections available for different test purposes. Please refer to the following table.

This tester is designed to test the aging resistance specially for rubber, plastic and some insulator materials. Different from normal aging oven, this tester has:
a. Temperature constancy
b. Temperature uniformity
c. Heat-up speed after door opened
d. Wind speed and air exchange rate of testing chamber
e. Seal of heat isolation of the testing chamber
f. Special apparatus for adjusting air exchange
g. Confirms to testing norms:

Measuring Method Of Air Change
This method measures the air change rate of the std type oven as follows
where:
N: number of changes of air per hour X: Power consumption during air change (W) Y: Power consumption during no air change (W) V: total volume of oven (cu. cm) D: Density of oven ambient air (g/cu. cm) △T: Temperature difference inside/outside oven (°C)

The oven is used for degradation study of plastics & rubber when subjected to heat in a rotational condition for a specified time. One day test at 70°Cis theoretically equivalent to a six-month usage in normal environmental condition. The machine is equipped with a motor-driven rotary plate. Hot air circulation will ensure even temperature distribution.

JIS K6742, CNS 4393
Put indenter on specimen and load force on the indenter into the chamber with heating speed of 1°C /min. When the indenter penetrates into the specimen for 0.1 mm, record the required temperature to judge the qualify of heat resistance. Normally, it is regarded to be qualified for over 80°C .(It can simultaneously test 3 specimens.)

IEC K6301,UL-1581
This tester used liquid media such as dry ice or alcohol as refrigerant. The specimen is mounted to a cantilever grips and soaked in a low temperature bath for 2.5 minutes (3 minutes for rubber) then strike the specimen with the tip of hammers to see whether it comes to facture or not.

This apparatus produces a heat gradient for measuring the heat seal of packaging or to find the optimum temperature for testing resistance of plastic, cloth or leather products.

This is to test the insulating characters between the conductors of the cable or the conductor with sheath by applying voltage slowly increasing upon the specimen to a certain level and see if the specimen can withstand that level of voltage.

This machine is used to test the fire resistance of organic materials like various wire and cables, PC boards, IC insulating sheath...etc. While testing, put sample at the tip of the flame that won't swing owing to the breeze. Let the flame burn for 15 seconds and out for another 15 seconds. Repeat another four times, ( Total Five Times ) and check the burning situation of the sample. Type A is of automatic model that is available to freely set the burning time, out time, repeat time and even available to be operated automatically.

JIS C3005
This is used to test bending resistance of rubber insulated wire. A certain length of sample is cut from a finished product and put through a related hole depending on the cable diameter. After rotating 200 rounds at the speed of 20 rpm. discharge the sample and the failure of the cable.

This tester is used to test torsion resistance of metal wire or rubber insulated cable. One end is fixed and the other is under continuous torsion till specimen breaks. The rotation can then be measured.

JIS C3004
This is tester is used to test the abrasion resistance of rubber insulated cable. A certain length of cable sample is fetched. One end is fixed ; the other is applied with a force to make the surface of the wheel is rotated at the rate of around 60 rpm. Then, see when the preset turning number is reached ; observe whether the coating of the cable is abraded and so to expose the conducting wire inside or not.

JIS C3005, K6723
This is used to measure the heat deformation of plastics, cable sheath and so on.
Put the specimen on the pressing plate. Apply a suitable temperature and load on it. After the preset time is reached, measure the thickness of the specimen. And then calculate the heat deformation rate.

UL 817
Feed the handset cord with power, and apply cyclic tensile test on it with pneumatic source. Record the test times and check the damaged portion.

UL-817
This machine is available to test the bending resistance of plug cable. When the sample breaks or achieves the preset time, the machine will stop automatically.

JIS C3004 , UL-62-1581
This tester is used to determine the quality of sheath or insulating material of cords. While testing, certain voltage is applied to the conductor and the electrode for a specified period of time. Then, the sample can be inspected to see if it can withstand this voltage value. The system is able to indicate the position of the pin holes and to count automatically the number of the pin hole.
