Electrical equipment for measurement, control and laboratory use - EMC requirements - Part 2-7: Particular requirements - Test configurations, operational conditions, test levels and performance criteria for devices with Ethernet-APL interfaces EN IEC 61326-2-7:2026

Publication date:   Aug 24, 2026

Scope

In addition to the requirements of IEC 61326-1, this part of IEC 61326 specifies the EMC test
requirements for process automation equipment using at least one Ethernet-APL (Ethernet
ADVANCED PHYSICAL LAYER) compliant port according IEC TS 63444. The type of equipment
covered by this document includes INFRASTRUCTURE DEVICES such as switches as well as
measurement and control devices. This document provides requirements for the EMC test
setups of the APL interface for devices intended for use in process control and process
measurement.

The other functions of the equipment remain covered by other parts of the IEC 61326 series.

NOTE Ethernet-APL uses IEEE Std. 802.3-2022 Ethernet Physical Layer 10BASE-T1L, suitable to be used for full-
duplex communication over a single balanced pair of conductors.
The test levels are based on the intended environment as stated in the product’s specification
or user documentation and selected appropriately from IEC 61326-1.
