ScopeIndustry Report
Europe's 50 Rarest Accredited Test Methods
We ranked every canonical test method in the ScopeMatch database by the number of accredited laboratories that hold it, then took the 50 rarest. These are the capabilities where accredited sourcing is most constrained -- grouped by how many labs hold each method.
Key findings
50 methods held by just 1 lab in all of Europe. If that single laboratory loses accreditation, closes, or reaches capacity, there is no accredited alternative anywhere on the continent. The most extreme cases include "General Unknown"-Screening, "RECOMMENDED OPERATING PROCEDURES FOR ANALYSIS IN THE VERIFICATION OF CHEMICAL DISARMAMENT, 2023 Edition, Paula Vanninen", "coryneforme" Stäbchenbakterien.

Methodology
This report identifies the 50 rarest canonical test methods across all six national accreditation bodies in the ScopeMatch database: DAkkS (Germany), UKAS (United Kingdom), COFRAC (France), RvA (Netherlands), ACCREDIA (Italy), and ENAC (Spain). Unlike the rare-test-methods report, no upper bound on lab count is applied -- the list simply shows the globally rarest 50 methods, ordered by ascending lab count.
"Canonical test method" means the normalised capability after mapping national-language scope document entries (e.g. "DIN EN ISO 6892-1:2020-06") to a single identifier. A laboratory is counted once per method regardless of how many national variants it holds.
Methods are grouped into rarity bands: 1 lab, 2 labs, 3 labs, 4-5 labs, and 6-10 labs. Within each band, methods are sorted alphabetically. All figures reflect the ScopeMatch database as of August 2026.
