What qualifies
Company records associated with the United Kingdom whose business descriptions match “on-site electromagnetic compatibility (emc) testing services” by meaning at the Exact setting.

Match quality
RevenueBase's August 25, 2026 study assessed 4,198 description/company pairs across matching settings. The publisher reports 86% good or better at Exact.
