Standards and accreditation

UKAS 8155 — ISO/IEC 17025:2017
Issue 009 dated 20 May 2026 lists the individual GCF-CC/GSMA/OMA requirements and location allocations. These named trial methods do not constitute a universal terminal or network certification scope.

What to confirm with the facility

  • Code B routes must supply the required network coverage and be suitable for the test, subject to contract review. MMS interoperability is A-only; field-site allocations are not interchangeable with laboratory scope.
  • Confirm the exact trial specification, terminal/network configuration, route coverage, report scope, availability and quotation.
