On-Site Testing

On-Site Testing is a conformity assessment method where compliance verification occurs directly at the manufacturer’s facility or the final installation site. For North American manufacturers of large, immobile, or complex industrial lines, shipping equipment to Accredited Laboratories is often logistically impossible or cost-prohibitive. This approach allows engineers to validate equipment in its intended operational environment without dismantling it.

This method is frequently used to satisfy requirements of the Low Voltage Directive (LVD) and the Electromagnetic Compatibility Directive (EMC). Engineers utilize calibrated portable equipment to measure electrical safety, noise emissions, and electromagnetic interference levels. It is particularly crucial for System-Level Testing, where multiple machines are integrated into a single production line, as the interaction between components can only be accurately assessed when fully assembled.

Successful on-site tests generate data that forms a vital part of the Technical File. While it offers convenience, the testing environment must be controlled to ensure results meet Harmonized Standards. Once passed, this data supports the Declaration of Conformity (DoC), proving the machinery is safe for the EU market.
