What is BS EN 50582 – Circuit integrity of optical fibres in a cable about?
BS EN 50582 is a European Standard that discusses optical fibres and cables.
BS EN 50582 specifies the details for the point of failure, continuity checking arrangement, test sample, test procedure and test report relevant to optical fibre cables tested.
The test determines the survival time for circuit integrity of the optical fibre cables when exposed to fire under the conditions either given in EN 50200 or given in EN 50577.
Who is BS EN 50582 - Circuit integrity of optical fibres in a cable for?
BS EN 50582 on circuit integrity of optical fibres in a cable is relevant to:
- Manufacturers of communication cables
- Manufacturers of electronic and electrical equipment and components
- Manufacturers of optic fibre cables
- Electrical engineers
- Quality testing personnel
Why should you use BS EN 50582 - Circuit integrity of optical fibres in a cable?
Circuit integrity is based upon the continuity of optical signal supply. The criteria that are used in BS EN 50582 for defining fire resistant optical fibre cables are deemed to demonstrate the ability of the cable to maintain a reliable signal transmission when subjected to fire.
The circuit integrity i.e. continuity of optical signal supply is deemed to be maintained if the maximum increase in attenuation does not exceed the value given in BS EN 50582 during the test duration.
Overall, BS EN 50582-compliant tests can demonstrate the extent to which optical fibres in a cable are fire-resistant by assessing the burning behaviour and ignitability of materials. This assessment can help you make the right selection of materials used for manufacturing cables, thus contributing to the enhanced performance, durability and safety of the end-application.
