===== CAN controller certification =====

The following standards are important for the certification of CAN(-FD) controllers:
  * ISO 11898-1: CAN  Data link layer and physical signaling for Classical CAN and CAN FD
  * ISO 11898-4: TTCAN Time-triggered communication 
  * ISO 16845-1: CAN Conformance Test Plan, since Oct 2016 it covers Classical CAN and the CAN FD protocols.\\ An update regarding REC increment on CRC error is available at [[https://www.can-cia.org/fileadmin/resources/documents/cia_rec-increment-on-crc-error.pdf|CiA web site]].

Test Lab [[http://www.cs-group.de/ | C&S group]] is testing compliance with
[[https://www.cs-group.de/testing/conformance-tests/can-osi-2/ | OSI Layer 2]]. The site also includes information on the CAN Processor Interface Tests, CAN Robustness Tests and specific C&S Add-on Tests.

Please visit [[https://www.cs-group.de/references/tested-products/can-osi-2-2/ | this]] for a table maintained by C&S for CAN Standalone Controller, Micro Controller and CAN-IPs.

----

The lab also tests OSI layer 1 for High- and Low-Speed Transceivers.
C&S maintains two tables for tested products 

  * [[https://www.cs-group.de/references/tested-products/can-osi-1-high-speed/ | High-Speed transceivers]]
  * [[https://www.cs-group.de/references/tested-products/can-osi-1-low-speed/ | Low-Speed transceivers]]

The Germany based [[http://www.ihr.de/index.php?lang=en | IHR]] is another well-known test expert, which is going to provide a test tool compliant to ISO 16845-1.
