Data record `std.tia-526-7-a.structure.uncertainty-overview`

Verified 2026-10-25 Confidence: Medium

Clause 4.3 of ANSI/TIA-526-7-A (2015) surveys the main sources of measurement uncertainty, among them test cord connections that differ from those used in service, source wavelength and spectral width, variation in coupling between source and launch cord, detector size, and mode field diameter mismatch between test interfaces.

Provenance. Where this record comes from and where it is used: the cited source, the record itself and the entry that cites it.

Provenance: the chain from source to entry.
