Here's a selection of text from the CM1213 data sheet.
The CM1213 family of diode arrays has been designed
to provide ESD protection for electronic components or
sub-systems requiring minimal capacitive loading.
These devices are ideal for protecting systems with
high data and clock rates or for circuits requiring low
capacitive loading. Each ESD channel consists of a
pair of diodes in series which steer the positive or negative
ESD current pulse to either the positive (VP) or
negative (VN) supply rail. A Zener diode is embedded
between VP and VN, offering two advantages. First, it
protects the VCC rail against ESD strikes, and second,
it eliminates the need for a bypass capacitor that would
otherwise be needed for absorbing positive ESD
strikes to ground. **The CM1213 will protect against
ESD pulses up to =B18kV per the IEC 61000-4-2 standard**
and using the MIL-STD-883D (Method 3015)
specification for Human Body Model (HBM) ESD, all
pins are protected from contact discharges of greater
than =B115kV.

Ram you are quite correct. I need IEC61000-4-2.
