Overview
SIST EN 50289-1-5:2002 is a European standard published by CLC that defines the test methods to determine the capacitance characteristics of finished communication cables. Specifically, this part focuses on electrical test methods related to capacitance for cables used in analogue and digital communication systems. It complements Part 1-1 of EN 50289, which outlines general requirements for electrical testing procedures.
This standard is crucial for ensuring that communication cables meet specific performance criteria, particularly in terms of mutual capacitance and capacitance unbalance to earth, facilitating reliable and efficient data transmission.
Key Topics
- Scope: Establishes procedures for measuring capacitance in both symmetrical and unsymmetrical communication cables, including coaxial and multicore cables.
- Definitions:
- Mutual capacitance (Cm): The effective capacitance between conductors under balanced conditions, measured in nanofarads per kilometer (nF/km).
- Capacitance unbalance to earth (Cu): The difference in capacitance to earth between conductors, measured in picofarads per kilometer (pF/km).
- Test Equipment:
- AC capacitance bridges operating in the 500 Hz to 2 kHz frequency range.
- Three-terminal bridges for balanced measurements.
- Two-terminal bridges for unbalanced measurements.
- Test Procedures:
- Measurements performed on cable samples at least 100 meters long.
- Calibration of test equipment including test leads.
- Specific methods depending on cable type:
- Unsymmetrical cables (e.g., coaxial cables): capacitance measured between inner and outer conductors.
- Symmetrical cables: mutual capacitance measured under both balanced and unbalanced conditions.
- Measurement of capacitance unbalance with all screens earthed.
- Result Expression:
- Mutual capacitance and capacitance unbalance normalized to 1 km cable length for standardization.
- Test Reporting Requirements:
- Test frequency and temperature.
- Sample length.
- Measurement type (balanced or unbalanced).
- Normalized mutual capacitance and capacitance unbalance values.
Applications
SIST EN 50289-1-5:2002 test methods are applied across several sectors involving communication cable manufacturing and quality assurance:
- Telecommunications Industry: Ensuring cable capacitance meets required thresholds to minimize signal distortion and attenuation in analogue and digital communication networks.
- Data Communication Systems: Verification of cable performance in transmitting high-frequency data signals reliably.
- Cable Manufacturing and Quality Control: Routine testing during production to maintain compliance with capacitance specifications, contributing to consistent product quality.
- Installation and Maintenance: Diagnosing cable faults related to capacitance irregularities that can affect network integrity.
- Standardization Compliance: Aligning with European and international testing norms for interoperability and certification purposes.
Related Standards
- EN 50289-1-1: Covers general requirements for electrical test methods applicable to communication cables and serves as a foundational reference for Part 1-5.
- EN 50290-1-2: Provides definitions essential for understanding communication cable characteristics and testing terminology.
- Other parts of EN 50289 series: Address different test parameters and methods essential for comprehensive cable performance evaluation.
By adhering to SIST EN 50289-1-5:2002, manufacturers and network operators can ensure precise capacitance measurements that directly affect cable performance in communication infrastructures. This standard supports consistent quality assurance practices that help maintain optimal system reliability and efficiency.
