What is BS EN 50289-3-8 - Communication cables about?
BS EN 50289 is a series on communication cables. Communication cables are a type of guided transmission medium. BS EN 50289-3-8 details the method of test to determine the ability of the sheath markings of a finished cable used in analogue and digital communication systems to withstand abrasion. BS EN 50289-3-8 will be read in conjunction with EN 50289-3-1, which contains essential provisions for its application. Depending on the kind of marking and as indicated in the relevant cable specification, one of the following two methods will be used:
- Method 1: is suitable for rigid marking types like embossing, indenting, and sintering
- Method 2: is applicable to marking types other than embossing, indenting, and sintering
Who is BS EN 50289-3-8 - Communication cables for?
BS EN 50289-3-8 on communication cables is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 50289-3-8 - Communication cables?
Cables are usually known to transmit electric energy; however, cables in telecommunications fields are used to transmit electromagnetic waves; they are called electromagnetic waveguides. BS EN 50289-3-8 defines two methods of determining the ability of the sheath markings which are Method 1 that describes that The abrasion test rig consists of a device designed to abrade the surface of the cable in both directions parallel to the longitudinal axis of the cable over a length of 40 ± 1 mm at a frequency of 55 ± 5 cycles/min. One cycle consists of one abrading edge movement in each direction. And Method 2 states that the apparatus follows the intent of that specified in Method 1, with the needle replaced by a wiping felt. These changes are made in the apparatus, which is a test set-up, to apply a force to the wool felt, a typical example is shown in BS EN 50289-3-8, wool felt, colour white, masses to apply a force to the sample and the apparatus shall allow a stroke length of 100 mm at a frequency of 6 to 12 cycles/min. Using BS EN 50289-3-8 you can specify the method of test to determine the ability of the sheath markings of a finished cable used in analogue and digital communication systems to withstand abrasion.
