Safety Testing of Cable Gland
ITC India Pvt ltd is a well equipped laboratory to test cable gland as per IEC/ BS EN/ EN standards. High tech environment and engineers are hired for testing your product. We have a good clientage for cable gland testing.
We are a NABL accredited laboratory covering all the scope of cable gland testing. The facility to test cable gland as per IEC 62444, EN 6121 is developed and testing is going in full swing.
All the equipment required are owned by the company. Let us explain the brief description of the testing procedure of cable gland as per IEC 62444.
This standard provides requirements and tests for the construction and performance of the cable glands. An ambient temperature (20±5) °C is maintained as per the requirement of the standard.
No. of samples =5
In case of a series of cable gland, 3 samples of largest and smallest and one sample of all other sizes of the same series shall be subjected to relevant test.
Cable gland are then classified for the test purpose according to Clause 6.1 to 6.5 .
After this durability of marking is checked with aliphatic solvent hexane. Documentation is provided by the supplier and compliance is checked by inspection.
Clause 8 construction is very important. All the relevant tests according to this clause are performed to check any flaws in construction. Measurements are done through calibrated Vernier caliper. Pre condition of the cable gland is done by keeping the cable gland in Environment chamber at ambient temp. With 40 – 60 % of humidity. The cable gland is kept inside the chamber for 24 Hours or more if specified by the supplier. Temperature and humidity of the chamber is well calibrated, so that it might not affect the pre conditioning. Resistant to corrosion is also be performed to check resistance against them.
After construction is the turn of mechanical properties, retention test apparatus is used for the testing, in which a load according to the table 2 is being applied for 5 min.
A cable anchorage test is performed on the cable gland with the cable anchorage test apparatus. The test mandrel is marked before load is applied and displacement is noted to check whether it pass or fail in the test. The test mandrel is pulled 50 times for 1 sec without jerks in the direction of its axis with load as per table 2. Also test Facility to test armored cable is available in our lab.
Before Resistance to impact test, the sample is placed in refrigerator for minimum of 8 hours. After removing from the refrigerator, impact test is carried out at the weakest point. The impact energy is calculated as per table 4. After the test there shall be no sign of disintegration nor shall there be any cracks visible.
Vitrek High voltage tester is used ti test the Ground Bound bond test where resistance between bonding terminal of the cable gland and each accessible metal part of cable gland.
Electric current test, Electromagnetic compatibility, degree of protection against external influences is also carried out on cable glands.
The last test to be performed is resistance to fire. Glow wire test apparatus is carried out at 650°C. For pass the test, there is no flame or glowing, if flame is produced, it must be extinguish with in 30 Sec or there should be no ignition on the tissue paper.
There are other standards according to which testing of cable gland is carried out in our lab which will be discussed in other topic…………
