1   Scope In addition to the requirements of International Standard IEC 61326‑1, this part of IEC 61326 treats the particular features for EMC testing of field devices with field bus interfaces. This part of IEC 61326 covers only the field bus interface of the equipment.

   NOTE  The other functions of the equipment remain covered by other parts of [IEC 61326](/search?q=IEC%C2%A061326) series. 

This part refers only to field devices intended for use in process control and process measuring. In this standard field devices with interfaces according to IEC 61784‑1, CP 3/2 and CP 1/1 as defined in IEC 61784 are covered. Other field busses may be included in future editions of this standard. The IEC 61784‑1 specifies a set of protocol specific communication profiles based on IEC 61158. The manufacturer specifies the environment for which the product is intended to be used and/or selects the appropriate test level specifications of IEC 61326‑1.
