The twenty second meeting of the ITU-T Conformity Assessment Steering Committee (CASC) was held in Geneva on 4 and 6 March 2026 during the ITU-T SG11 meeting. The meeting covered the status of Testing Laboratories (TLs), outcomes of an ITU survey on the use of ITU-T Recommendations in national conformity frameworks, assessment of maturity for Pillar 1/ITU Mark, and collaboration with Global Accreditation Cooperation Incorporated.
Status of ITU Testing Laboratories Database: As of 27 February 2026, 15 testing laboratories were registered in ITU Testing Laboratories Database (
https://itu.int/go/tldb). Since November 2025, some laboratories started reassessment of their accreditation. Also, Testing Laboratories, which are recognized by ITU, are encouraged to register ICT products tested against ITU-T Recommendations in the ITU Product Conformity Database (
https://itu.int/go/tcdb).
Outcomes of ITU Survey: In December 2025, based on SG11 decision, ITU launched a survey on the use of ITU-T Recommendations in national conformity assessment frameworks, including type approval (
TSB Circular 96). The survey received 17 responses from 15 countries, showing interest in the ITU Conformity and Interoperability (C&I) Programme (
TD909/GEN), reflected by the number of Testing Laboratories utilising ITU-T Recommendations and expressing a desire to adopt new ITU-T Recommendations across various telecommunication domains within the national conformity assessment framework. Furthermore, it was noted that these outcomes may be used as success stories. It was agreed to notify all ITU-T Study Groups (SGs), TSAG, and ITU-D SG2 Q4/2 regarding the findings of this survey. It has been sent as
SG11-LS117.
Assessment of maturity of Pillar 1 and ITU Mark concept: Following Resolution 177 of PP-22, the TSB developed criteria for assessing Pillar 1 maturity and a draft ITU Mark concept. CASC discussed related contributions and agreed on preparing the draft text that TSB Director can use for reporting to Council on the assessment of maturity of Pillar 1 of ITU C&I Programme and the need of ITU Mark in general. The draft report is available in
SG11-TD939-R1/GEN. It was agreed to request TSB to present updated information on ongoing discussion on draft ITU Mark concept at the forthcoming Regional Groups of SG11.
List of ITU-T Recommendations for ITU Mark: Based on suggestions given at the CASC meeting held in November 2025 (see Annex 6 to
SG11-R7), TSB prepared the list of ITU-T Recommendations proposed to be used for the ITU Mark concept which was extracted from the scope of accreditation of TLs recognized by ITU (
SG11-TD860/GEN). This document was noted by the meeting.
Collaboration with Global Accreditation Cooperation Incorporated: The overview of Global Accreditation Cooperation Incorporated, which assumes roles of IAF and ILAC, was presented by Mr Brahim HOULA (Chair, Global Accreditation Cooperation Incorporated) at the SG11 opening plenary (
SG11-TD920/GEN).
WHO representative gave a presentation on WHO-ITU standards to “Make listening safe” (
SG11-TD971/GEN). It was noted that these standards can be good candidates for TL accreditation. In this regard, Global Accreditation Cooperation Incorporated was requested to explore a possibility on initiating a call for TL accreditation on H.870 and provide timelines for updating related procedures and MoUs. It was noted that further offline discussion would be needed among TSB secretariat, WHO and Global Accreditation Cooperation Incorporated on particular issues discussed at this meeting.
The next CASC meeting is planned for July 2026 during the SG11 meeting in Geneva. More details about CASC results are available in
SG11-TD858/GEN and its webpage at:
