VREF is the voltage at the reference pin (VREF_IN for SCL_IN and SDA_IN, or VREF_OUT for SCL_OUT and SDA_OUT); nominally 5.0 V.

Off leakage test conditions are described in the HDMI Compliance Test Specification 1.3b Section 8, Test ID 8-14: “Remove power (mains) from DUT. Connect CEC line

to 3.63 V via 27 kΩ ± 5% resistor with ammeter in series. Measure CEC line leakage.”
