ISO 20911:2020 pdf download.Radio frequency identification (RFID) tyre tags — Tyre attachment classification
1 Scope
This document specifies RFID tyre tag classification of the different technologies (embedding, patching,sticking) to benefit the user’s understanding of their differences, targets, possible applications as well as their limitations.
This document includes:
— generic description of the main features for each technology;
— marking recommendation.
This document excludes:
— references to items related to tyre quality and the testing thereof;
— detailed references to embedded locations;
— detailed references to rubber compound properties;
— detailed references to tyre manufacturing processes.

4 RFID technology classification
4.1 Embedded
4.1.1 Embedding technology
Embedded technology is intended to be used throughout the life of the tyre. Possible uses are manufacturing, service, retreading, removal and/or recycling and scrapping.
Since the tyre is composite, made of several layers and compounds, the RFID tag can be placed into the tyre in or between any layer and during any point of the manufacturing process. This shall be done under the responsibility of the tyre manufacturer.
4.1.2 Embedded location/positioning
4.1.2.1 Generalities
RFID tyre tags are radio-frequency devices. Performance and functionalities may be influenced by several parameters, including but not limited to:
— dielectric and conductive properties of surrounding materials such as
— detuning of the RFID tyre tag,
— attenuations and/or shielding of radio propagation, and
— induced currents;
— mechanical stresses and strains (possible damage of the RFID tyre tag).
4.1.2.2 Location
Therefore, design, placement and orientation of the RFID tyre tag into the tyre, should be chosen appropriately by the tyre manufacturer to ensure RFID-enabled tyre conformance as per ISO 20912. An example of one such area is shown in Figure 1.
4.2 Patch
4.2.1 Patching technology
Patching technology is intended to be used from the patch date of installation until the tyre’s end of life.
Possible uses are for:
— logistics and traceability;
— product information at the tyre dealer;
— RFID retrofitting of already manufactured (new) or tyres in service;
— after retreading for non-RFID casings;
— RFID tag replacement, as needed (e.g. embedded solution damaged, non-functional).
As a consequence, RFID enabled tyre traceability will depend on the date of the patch installation.
