Have never seen this in a product safety standard, but the phrase is commonly used in building code (see NEC -> NFPA70).
For building code, would be where derived separately from the distribution panel and/or distribution transformer. Independent circuits do not have to be older than 18 years.

I have looked in the Online Electrotechnical Vocabulary, a number of product specific safety standards and contacted a NRTL without success. William B.
