SANS 17020: Criteria for Accredited Inspection Bodies for Electrical Installations

Introduction

SANS 17020, aligned with ISO/IEC 17020, outlines the requirements for the operation of inspection bodies performing inspections, including those for electrical installations in South Africa. It ensures that Accredited Inspection Bodies (AIBs) maintain technical competence, impartiality, and consistency when conducting inspections, such as those required for issuing Certificates of Compliance (CoCs) under the Electrical Installation Regulations. This standard is critical for professionals in the electrical industry, including inspectors and contractors, to ensure compliance with safety standards.

Key Requirements

• Accreditation by SANAS: Inspection bodies must be accredited by the South African National Accreditation System (SANAS) to SANS 17020, demonstrating competence in inspection processes.

• Technical Competence: AIAs must employ qualified personnel with expertise in electrical installations, adhering to standards like SANS 10142-1 (Wiring Code).

• Impartiality and Independence: Inspections must be conducted without bias, ensuring objective and reliable results.

• Quality Management System: Implement documented procedures for inspections, reporting, and record-keeping to ensure consistency and traceability.

• Inspection Procedures: Follow standardized methods for inspecting electrical installations, including verification of wiring, earthing, and safety devices.

Why It Matters

SANS 17020 ensures that electrical inspections are conducted by competent, impartial bodies, protecting public safety by verifying compliance with standards like SANS 10142-1. It is a legal requirement under the Electrical Installation Regulations for certain installations (e.g., sub-reticulation systems) to be inspected by an AIA, with non-compliance risking fines, safety hazards, or invalid CoCs. This standard builds trust in the inspection process, ensuring electrical systems are safe and reliable.

How It Applies

AIAs use SANS 17020 to conduct inspections of electrical installations in residential, commercial, or industrial settings, particularly for issuing CoCs required for property transfers or new installations. For example, an AIA might inspect a home’s wiring to ensure it meets SANS 10142-1 before issuing a legal report. The standard guides the accreditation process and ensures inspections are thorough and standardized.

Recent Updates

The latest version of SANS 17020 (aligned with ISO/IEC 17020:2012) emphasizes enhanced requirements for impartiality, risk-based inspections, and digital reporting. While specific updates for electrical inspections are not detailed in public sources, alignment with international standards ensures global best practices. Professionals should check the SABS for the latest edition.

Compliance Tips

• Select SANAS-Accredited AIBs: Ensure the inspection body is accredited to SANS 17020 for electrical inspections.

• Verify Inspector Qualifications: Confirm inspectors are trained in SANS 10142-1 and related standards.

• Maintain Records: Keep detailed inspection reports and CoCs for regulatory compliance.

• Stay Informed: Regularly review updates to SANS 17020 and the Electrical Installation Regulations via the SABS or industry bodies.
