ISO 50001 Details
What It Is
ISO 50001:2018 is an international certification standard for Energy Management Systems (EnMS). It provides a systematic framework to improve energy performance, including efficiency, use, and consumption. Applicable to all organizations and sectors, it follows the Annex SL High-Level Structure and PDCA cycle for structured energy planning and continual improvement.
Key Components
- **Clauses 4-10Context, leadership, planning (energy review, SEUs, EnPIs, EnBs), support, operation, evaluation, improvement.
- Energy policy, data collection plans, operational controls, procurement criteria.
- Built on risk-based thinking and measurable indicators.
- Optional third-party certification per ISO 50003.
Why Organizations Use It
- Reduces energy costs (4-20% savings), enhances resilience, cuts GHG emissions.
- Meets regulatory expectations, supports ESG reporting.
- Manages supply risks, improves procurement.
- Builds stakeholder trust via auditable performance.
Implementation Overview
- Phased: gap analysis, planning, deployment, check-act.
- Involves metering, training, audits.
- Scalable for SMEs to multinationals; 12-18 months typical.
AS9110C Details
What It Is
AS9110C is the international quality management system (QMS) standard for aviation maintenance, repair, and overhaul (MRO) organizations. It extends ISO 9001:2015 with aerospace-specific requirements focused on safety-critical processes. Its primary scope covers MRO activities ensuring airworthiness, using a risk-based thinking (RBT) and PDCA methodology.
Key Components
- Core pillars: context, leadership, planning, support, operation, evaluation, improvement (Clauses 4-10).
- Aviation additions: configuration management, counterfeit parts prevention, human factors, traceability.
- Built on ISO High Level Structure (HLS); no fixed control count, emphasizes documented information.
- Certification via accredited registrars with internal audits and management reviews.
Why Organizations Use It
- Meets customer/OEM contracts and regulatory alignments (FAA/EASA Part-145).
- Mitigates safety risks, reduces rework, ensures traceability.
- Boosts market access, operational efficiency, stakeholder trust.
Implementation Overview
- Phased: gap analysis, process design, training, pilots, audits.
- Applies to MROs of all sizes globally; requires 3+ months operational data pre-certification.
