The H1 Cable Test Specification (Document FF-844) is designed for manufacturers developing cables for Foundation fieldbus H1 (31.25 kbit/s) installations.
The specification test cases, based upon the IEC 61158-2:2003 standard, include (but are not limited to) impedance, capacitive unbalance, connector pin-outs, and attenuation.
Cable manufacturers can submit their test reports to the Fieldbus Foundation, which will initiate a cable registration process in the near future.
The Fieldbus Foundation Manager for Fieldbus Products, Stephen Mitschke, said, "The Fieldbus Foundation is helping to ensure robust and reliable fieldbus physical layer performance with the release of this new H1 cable specification.
End users will be the main beneficiaries of the rigorous suite of cable test cases available in the specification".
