Witnessing of Factory Acceptance Tests (FAT) - Inverters

Kiwa conducts independent inspections, audits, and evaluations of manufacturing processes, production controls, documentation systems, and supplier performance. These activities help organizations reduce defects, strengthen supply chain reliability, and ensure compliance with industry standards and customer-specific requirements across complex global value chains.
Supply chain failures, inconsistent production quality, and unverified supplier processes can lead to costly delays, safety risks, and non-compliance. Many aerospace, automotive, oil and gas, and high-reliability industries mandate structured supplier quality programs and documented oversight. Independent verification improves transparency, reduces risk, and supports long-term relationships with key customers and regulators.
