Every component we ship has passed a full electrical test regimen — before it ever leaves our facility.
Electrical testing is not an optional step in our process. At C.A. Spalding, 100% of components undergo hipot and electrical testing as a standard part of production — not as a final audit sample, and not on request. This means that every transformer, inductor, wire harness, and electromechanical assembly we ship to customers including Boeing, Eaton, Tesla, 3M, and Rockwell Automation has been individually verified to meet its electrical specifications before it reaches your dock.
For engineers and supply chain managers in aerospace, automotive, and defense, this is a meaningful distinction. A component that passes our production floor has already passed dielectric withstand, output voltage, inductance, resistance, and turn ratio verification. Your incoming inspection starts from a much stronger baseline.
Our Electrical Testing Capabilities
We configure test protocols to your specific requirements — voltage range, frequency, tolerance, and applicable industry standards. Testing is performed on production-intent equipment, calibrated and maintained under our ISO 9001:2015 and IATF 16949:2016 quality management systems.
Hipot (dielectric withstand) testing High-voltage stress testing applied to each component’s insulation system, verifying it can withstand the required voltage without breakdown. Test parameters are set to your specified operating voltage and safety margins.
Output voltage testing Confirms power delivery meets specified levels under defined load conditions.
Inductance measurement Verifies electromagnetic properties are within design tolerances.
Resistance testing Identifies short circuits, poor connections, or conductor anomalies before shipment.
Turn ratio analysis Validates transformer winding configuration and performance.
Functional testing Confirms components operate correctly under normal operating conditions — completing the picture alongside stress testing.
How Test Protocols Are Established
When a new component enters production, our engineering and quality teams develop a test protocol based on your drawings, specifications, and applicable standards. Acceptance criteria, test parameters, and documentation requirements are established before the first production unit is built — not after.
During production, every unit is tested against that protocol. Results are recorded, trends are tracked, and any unit outside specification is quarantined and dispositioned before the lot ships. Full traceability documentation is available to support your compliance and audit requirements.
Certifications
Our testing processes operate under ISO 9001:2015 and IATF 16949:2016 certified quality management systems — meeting the process control and documentation standards required by automotive OEMs, aerospace primes, and other regulated industries.
