Mercury analysis using spark‑AES is not recommended because a strong iron spectral line interferes with the mercury signal, making accurate determination unreliable. For legislated mercury limits (often as low as 0.0001 %), laboratories must use alternative techniques such as glow‑discharge mass spectrometry, XRF, cold‑vapor AA, or ICP‑MS.

Many international certification schemes such as Nadcap (aerospace) and ship classification societies explicitly require ASTM E1251‑17a for supplier laboratories. Accreditation bodies such as ANAB (ANSI‑ASQ National Accreditation Board) list E1251 as an approved test method under ISO/IEC 17025.
