Our Engineering and Design capability for recertification and accreditation of explosion-protected electrical equipment includes a rigorous and standards-compliant process to ensure the safe and continued use of instruments in Group I (coal mining) hazardous areas under the IECEx Scheme and AS/NZS 3800.
Key Inclusions:
Detailed inspection and review of equipment to determine if it conforms to original certification conditions.
Identification of any modifications, wear, or non-conformities impacting compliance.
Verification that design documentation (drawings, specifications, materials) aligns with applicable IECEx standards (e.g. IEC 60079 series) and AS/NZS 3800.
Engineering assessment of any required modifications, repairs, or upgrades to restore or maintain certification.
Risk assessment in accordance with AS/NZS ISO 31000 and coal mining-specific hazard criteria.
Development of detailed engineering plans for compliant repair or modification of flameproof, intrinsic safety, or other types of protection.
Use of certified components and adherence to original design intent or accepted equivalence.
Implementation of compliant repair practices and documentation according to AS/NZS 3800 requirements.
All work is performed within certified overhaul facilities (e.g. with IECEx Service Facility Certification).
Execution of tests (e.g. flameproof integrity, insulation resistance) as per original certification requirements.
Compilation of test results for inclusion in recertification documentation.
Preparation of full engineering dossier including updated drawings, test reports, conformity assessments, and service records.
Ensuring traceability of components and work completed for audit purposes.
Liaison with IECEx Certification Bodies (ExCBs) and Australian authorities (e.g. Resources Regulator, Queensland Mines Inspectorate) for formal review and re-certification approval.
Ensuring compliance with regulatory obligations under Australian or International Coal Mining Health and Safety Regulations.
