Consultation meeting
•October 2015
Gap analysis
•Early 2016
Work on umbrella
specification
•2Q 2016
Drafting completed
• July 2018 (C)Aug. 2018 (A)
ITU edition launched
•Nov. 2019 (P)
WHO edition launched

How we got here
• Europe: Existing hard-threshold standard;Evolving sound-dose standard
• Big void elsewhere• No guidance on communication to device users
• Formal approval on 29 Aug.2018 as an international standard: Recommendation ITU-T H.870
• ITU edition published in Nov. 2018• Translation available into the six
UN languages

What else? And where from now?
• WHO & ITU Toolkit (2019/02)
– What can different stakeholders do (governments, industry, civil society)
• Derivative work:
– H.871 - Safe listening guidelines for personal sound amplifiers
• Advocacy, awareness
• Standardization front:
– HSTP-CONF-H870: Specification on how to check compliance to H.870
– Future improvements to H.870
– New standard on safe listening in public spaces

Selecting a test laboratories
▪ Accredited Testing Laboratory on ISO/IEC 17025 (first, second or third party)
▪ Joint ITU/IECEE Testing Laboratory recognition procedure, certification scheme
▪ ITU test events (call for bid among Testing Laboratories)
▪ ITU conformity testing Pilot projects (e.g. develop test specifications, identify test labs, conduct tests)

Technical experts on ITU-T H.870 are needed for selecting Testing Laboratories
![Page 9: ITU-T H.870 Safe listening devices and systems · •Deep technical knowledge and experience on ITU-T H.870 and relevant test specs •Experience in testing of ICT products against](https://reader035.fdocuments.in/reader035/viewer/2022071516/613878fa0ad5d20676494746/html5/thumbnails/9.jpg)
Common criteria for ITU-T Technical experts
• Expert from ITU members
• Deep technical knowledge and experience on ITU-T H.870 and relevant test specs
• Experience in testing of ICT products against ITU-T H.870 and competence to review Test Report(s)
• Do not have conflict interest with assessed TL (NOdirect/contractual, personal/corporative relationship)
• An experience in ISO/IEC 17025 and knowledge of IEC/ILAC rules will be an advantage

Potential approach
Appoint ITU-T technical experts who have relevant expertise (to assess TL and/or a bid review)
Recognize/identify testing laboratories (TLs) which have competence to test ICT products against ITU-T H.870 using relevant test specs
Test ICT equipment in TLs on compliance with ITU-T H.870
Register products in ITU Database (create a QR code)

ITU Product Conformity Databasehttp://www.itu.int/go/tcdb
ICT Products tested against ITU standards using ITU test specifications
The database contains different categories of ICT products (more than 500 entries):
• E-health devices• Mobile phones• Ethernet services• IPTV• MNP systems
The database is used by different stakeholders. For instance (not limited to):
• Vendors of ICT products (expansion of sales)
• Suppliers (mitigation of risks under supplier’s responsibility)
• Testing laboratories (promoting TLs expertise)
• Customers (increasing brand loyalty)

BACKGROUNDMany mobile phones do not work properly with car’s HFT’s system and thereby significantly degrading the speech quality of the complete system
