Contact discharges are performed at conductive surfaces, while air discharges are performed at
insulating surfaces. Indirect contact discharges are performed on the measurement setup horizontal
and vertical coupling planes as defined in CENELEC EN 61000-4-2.

For the definition of integral antenna, removable antenna, antenna port, and the device
classification, refer to the ETSI EN 301 489-1. For the contact and air discharges definitions, refer
to CENELEC EN 61000 4-2.

NINA-B4 is manufactured with consideration to specific standards that minimize the occurrence of
ESD events; the highly automated process complies with IEC61340-5-1 (STM5.2-1999 Class M1
devices) standard
, and designers should subsequently implement proper measures to protect
any pin that might be exposed to the end user from ESD events.
Compliance with the standard protection level specified in EN61000-4-2 is achieved by including ESD
protection close to any areas accessible by the end user.
