How this limit library is sourced and used

Each limit page identifies its standard or regulation, edition, source locator, review date, and the measurement conditions that must match before a result is compared. The tables are engineering-reference data, not a substitute for the applicable publication or a certification test plan.

Choose the standard by product type, market, and approval context.
Match the edition, class, port or emission type, detector, frequency range, unit, facility, and distance.
For paid standards, follow the named edition and locator; the library summarizes data and does not reproduce the standard text.
