IEC 61156-2-2:2001

Overview

IEC 61156-2-2:2001 is an international standard published by the International Electrotechnical Commission (IEC) that specifies Capability Approval requirements for multicore and symmetrical pair/quad cables used in digital communications, particularly for horizontal floor wiring. This sectional specification complements IEC 61156-1 and IEC 61156-2 standards, providing a focused framework for cable manufacturers and customers on quality assurance and production processes. It aims to guide manufacturers and clients on assessing and maintaining capability approval for these specific types of digital communication cables.

Key Topics

• Scope and Application
  The standard applies to multicore cables designed for digital data transmission in horizontal floor wiring environments, covering construction details, quality plans, and manufacturing processes. It serves as a guideline for third-party capability approvals but is also relevant for second-party or self-certification.

• Capability Manual Content
  Manufacturers must maintain a Capability Manual that includes:

  • References to relevant standards and specifications
  • Detailed cable construction information (conductors, insulation, screening, sheath, dimensions)
  • Descriptions of unique cable characteristics not directly covered by existing standards
  • Identifying production processes and their limits for each manufacturing phase
  • Policies for re-manufacturing and repair operations

• Quality Plans and Control
  Establishing quality plans is essential, focusing on:

  • Manufacturing stage identification
  • Process-dependent characteristics and tests
  • Test procedures, acceptance criteria, and sampling frequencies
  • Statistical quality trends monitoring to ensure continuous compliance with standards

• Maintenance of Capability Approval
  The standard discusses methodologies to sustain capability approval status, emphasizing ongoing quality control and adaptation to production changes when necessary.

• Normative References
  IEC 61156-2-2 refers to other integral normative documents such as IEC 61156-1 and 61156-2, which provide generic and sectional specifications for symmetrical pair/quad cables.

Applications

IEC 61156-2-2 is crucial for ensuring the performance and reliability of horizontal floor wiring cables in digital communication systems. Applications include:

• Office and Commercial Buildings
  Structured cabling installations requiring standardized, high-quality cables for data networks ensuring signal integrity.

• Data Centers and Network Infrastructure
  Within data centers where reliable horizontal cabling supports high-speed data transmission and minimizes interference.

• Telecommunications and IT Systems
  Deployment in environments demanding compliance with international cable standards for connectivity and interoperability.

• Manufacturing Compliance and Certification
  Assists manufacturers in demonstrating compliance with international quality standards to customers and certification bodies.
