Certified Inspections & Audits
Comprehensive Pre-Shipment Inspection of Customized LED Systems
Our client engaged us to conduct a comprehensive Pre-Shipment Inspection for custom LED fixtures tailored for a complex architectural lighting project. Given the expensive and complex installation process, identifying component defects prior to export from China was vital to avoid costly post-delivery retrofits and installation delays. We carried out a rigorous multi-stage quality inspection directly at the manufacturing facility to evaluate physical assembly, electrotechnical characteristics, and overall order specification compliance before authorizing shipment.
Our approach
To ensure complete compliance with the project specifications, our engineers performed numerous checks and tests at the factory before box packing and dispatch. We conducted a thorough visual and physical control of LED fixtures, performing an inspection for visible defects and damage, checking correct operation under high and low temperatures as well as water resistance. We verified the quality of materials used in production alongside critical mechanical parameters, such as overall fixture dimensions and the structural reliability of mounting elements. Our team performed comprehensive electrotechnical testing by powering up the fixtures to inspect signal transmission, pixel addressing correctness, and brightness uniformity across LED lights. Finally, we carefully examined all connectors to eliminate any risk of short circuits or contact failures during on-site installation.
The challenge
To verify material quality, we had to disassemble several sample units, extract key components, and send them to specialized laboratories for testing. Inspecting physical dimensions and electrotechnical parameters required a large amount of man-hours and meticulous attention to detail. Furthermore, to ensure the fixtures would operate under extremely high and low temperatures and meet an IP67 waterproof rating, numerous samples had to be tested in specialized testing equipment, which was a time-consuming process. Finally, verifying signal transmission and pixel addressing correctness required repeatedly assembling a system of multiple fixtures, a power supply, and a controller on the factory floor, testing it, and then disassembling it for the next batch, taking up significant space and time.
The execution
We carried out a rigorous, standardized inspection in strict accordance with ANSI/ASQ Z1.4 (AQL Level III). As a result of the inspection, our team identified several defects and issues across different criticality levels. We provided the client with a detailed inspection report featuring comprehensive statistics, data analysis, as well as extensive photo and video documentation. Once the factory rectified all previously identified issues and our specialists completed a re-inspection, we issued a final approval report confirming that the products were cleared for shipment.
