- Evidence of Suitability ("A5G3")
Evidence of Suitability (A5G3) as defined in the National Construction Code (NCC), outlines the framework for demonstrating that materials, products, forms of construction, or designs comply with the relevant Performance Requirements or Deemed-to-Satisfy Provisions of the NCC. This is a critical step in ensuring the safety, reliability, and compliance of systems and equipment, particularly in the context of fire safety.
For fire safety systems, equipment, and measures, evidence of suitability must establish that the chosen solutions meet stringent safety and performance criteria. These solutions include fire detection and alarm systems, fire suppression systems, emergency lighting, and exit signs.
Supporting documentation must be clear, credible, and traceable, ensuring that all components contribute to the building's overall fire safety strategy.
Evidence of Suitability establishes the compliance pathway for achieving robust fire safety in buildings, ensuring the systems perform effectively during emergencies.
Acceptable Forms of Evidence
To satisfy A5G3, acceptable evidence may include:
- Accreditation Certificates – A certificate issued by a State or Territory accreditation authority stating that the properties and performance of a building material or method of construction or design fulfil specific requirements of the NCC. Certification is typically issued by an accredited certification body confirming compliance with the NCC or relevant product Standards.
- Testing Reports – Independent testing reports from Accredited Testing Laboratories, documenting how the product or system meets performance benchmarks (e.g., fire resistance levels, luminance, or durability under fire conditions).
- Product Technical Statements – Manufacturer-provided documentation explaining how the product or system complies with specific NCC requirements or relevant standards.
- Expert Judgements – Assessments by qualified professionals confirming compliance with the NCC in cases where prescriptive evidence may not fully apply.
- CodeMark or WaterMark Certification – Where applicable, these certifications can streamline acceptance under the NCC framework.
Fire Safety Specific Applications:
For fire safety systems and measures, A5G3 ensures that:
- Materials (e.g., fire-rated walls or fire doors) are tested for compliance with AS 1530 (fire resistance and non-combustibility).
- Products (e.g., fire extinguishers, alarms, sprinklers) meet the relevant sections of AS 1851 (routine service of fire protection systems and equipment).
- Forms of Construction (e.g., fire compartments, separation walls) meet performance metrics for fire containment and structural stability.
- Designs (e.g., escape routes, egress lighting, or emergency systems) meet the intent of the NCC’s fire safety Performance Requirements.
