EUROLAB laboratory provides testing and compliance services within the scope of EN 60811-506 standard. This part of the EN 60811 standard gives the procedure to perform low temperature impact tests on extruded insulations and sheaths.
The EN 60811 series specifies test methods to be used to test non-metallic materials of all types of cables. These test methods are intended to be referenced in standards for cable construction and cable materials.
Non-metallic materials are typically used for insulation, sheathing, bedding, stuffing or taping inside cables.
These test methods are considered basic and basic and have been developed and used for many years mainly for materials in all power cables. It has also been widely adopted and used for other cables, especially fiber optic cables, communication and control cables, and cables for ships and offshore applications.
This part of IEC 60811 will be used in conjunction with IEC 60811-100. All tests should be performed at least 16 hours after extrusion or crosslinking of the insulation or coating compounds. The tests will be carried out at the temperature specified in the relevant cable standard.
This cold impact test is designed for sheathed cables of all types, regardless of the insulation type of the cores, and for the insulation of wires, cables and unsheathed flat cables if required by the relevant cable standard. The insulation of sheathed cables is not directly subjected to cold impact testing.
The test apparatus should be placed on a sponge rubber pad approximately 40 mm thick and kept in a suitable low-temperature cabinet before and during the experiment.
The apparatus and cable parts to be tested should be placed side by side in a suitable low temperature cabinet and kept at the specified temperature. The contents of the refrigerator should then be allowed to cool for not less than 16 hours, including the cooling time of the appliance. If the instrument has been pre-chilled, a shorter cooling time is allowed, but not less than 1 hour, provided that the test pieces have reached the prescribed test temperature.
