PEARL Inspect and Test Standards provide inspection, cleaning, testing, and documentation instructions and guidelines that when followed by trained technicians will provide evidence that an electrical device is free of inherent flaws or faults.

The PEARL Inspect and Test Standard is neither a reconditioning standard, nor does it promise extended service life or improve reliablity. It is intended to indicate that the equipment or device in its present state shows no indication of damage and tests satisfactorily to manufacturer or industry operational specifications.

PEARL member companies affix the green PEARL Inspected & Tested Seal to electrical equipment that has passed the PEARL
Inspect & Test Standards.

Organized by type of equipment or apparatus, you can view and/or download any of the individual PEARL Inspect & Test Standards in PDF file format by using the links below.
