What is BS EN 60793-1-53 - Measurement methods and test procedures about?
BS EN 60793 is a series on measurement methods and test procedures. Measurement methods and test procedures are the quantifications of attributes of an object or event, which can be used to compare with other objects or events. BS EN 60793-1-53 provides a practical method for evaluating fibre performance in a defined environment.
Who is BS EN 60793-1-53 - Measurement methods and test procedures for?
BS EN 60793-1-53 on measurement methods and test procedures is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 60793-1-53 - Measurement methods and test procedures?
Measurement is a cornerstone of trade, science, technology, and quantitative research in many disciplines. The purpose of BS EN 60793-1-53 is to define a test that determines the suitability of sub-category A1a to A1d multimode fibres and class B and C single-mode fibres to withstand the environmental condition of immersion in distilled or demineralized water which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of the effects of immersion in water over a given period.
To ensure the required repeatability on optical measurements, the length of the specimen is at least 1 000 m for fibre sub-categories A1a to A1d, and at least 2 000 m for fibre classes B and C. The amount of the specimen outside of the tank is minimized and, if it exceeds 10 % of the overall specimen length, this should be reported. The specimen is placed in a tank that is filled with water held at 23 °C ± 5 °C and held there for 30 days. The attenuation and coating strip force of the specimen is then monitored. Conduct the procedure in accordance with IEC 60068-2-18, Test R, with the “head of water” being not applicable (the head of water is used to test for “water tightness” of electrotechnical products, but it is not required in this application). Using BS EN 60793-1-53 you can provide a practical method for evaluating fibre performance in a defined environment through water immersion tests.
