Principles for Waterproof Gland Test

Cable glands are for cables with connectors while cable gland waterproof are generally cable glands for unarmoured cable. For waterproof glands, countless experiments to carry out the final quality verification should be done before mass production in order to ensure the better quality of products. Therefore, those products with a better waterproof-grade on the current market actually have already been tried many times at the beginning and such experiments are generally carried out by the suppliers and buyers. The advantage of that is the results of the experiment will be more persuasive. The waterproof gland should be tested abide by the following two principles:


1. The norms

Any material or technique used in the test should be as the same as the normal products. Therefore, the products used in the waterproof-test must be those produced under the normal production conditions, otherwise, it can easily cause the inaccuracy of the result if choosing those high-grade materials or  specially processing the process during the production on purpose.


2. The testing environment should be more strict

The purpose of the test is to enable the products to meet the highest requirements, or to make the products at a specific level to achieve that level or even  higher than their own level. Therefore, during the test, like a IP68 waterproof joints may be placed under 10 meters of water and work for two weeks to ensure that the product won't seep into water. For another example, put the joint on the depth of 100 meters under the water to do a destructive test lasting for 12 hours to ensure a performance of product.


Different manufacturers are using different ways and in a different depth of water to do the waterproof gland test. In order to make the product suitable for its own grade, the test should not only be standardized, but also more stringent so as to ensure the experiment results.
