The new edition of IEC 61282-2:2023 provides updated requirements and recommendations for the design, construction, and testing of indoor optical fibre cables. The standard ensures that indoor optical fibre cables meet the required performance and safety standards for data transmission and reception, and promotes interoperability between different optical fibre cable systems and components.

Covers electrical insulation, power/air consumption, and pneumatic airflow characteristics.

The is finalizing IEC 61298-2 Edition 3.0 , a major update titled "Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions" . Maintained by the IEC TC 65/SC 65B subcommittee, this standard establishes the official international protocols for testing both analogue and digital industrial instrumentation.

Modern instrumentation relies heavily on digital bus communications (e.g., PROFINET, Modbus, Ethernet/IP). The new edition provides revised evaluation criteria for digital transfer functions and clarifies how data acquisition lag should be calculated during baseline testing.

The International Electrotechnical Commission (IEC) standard 61298-2, titled "Process automation - Guide on inputs and outputs for process automation - Part 2: Part 2: Data structures and elements for process automation", has undergone updates. The latest version, IEC 61298-2:2019, aims to provide guidance on the identification, representation, and exchange of information in process automation. This report summarizes the key new aspects of IEC 61298-2:2019.

: The Device Under Test (DUT) must be powered on and cycled through its full scale to eliminate mechanical memory and ensure thermal equilibrium.

The full title, "Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions," precisely describes its function. The standard provides a set of globally recognized methods to test and report on the fundamental performance characteristics of process instrumentation under ideal, controlled conditions (reference conditions). This standardization is essential for comparing products from different manufacturers on a like-for-like basis and ensuring that devices perform as specified from the moment they are installed. The new edition of IEC 61282-2:2023 provides updated

: Measuring how rapidly a device processes an input step-change under steady reference environments.

Specifies procedures to measure both start-up drift and long-term drift to predict maintenance cycles. Significant Updates in Edition 3.0

: Monitor the live publication progress via the IEC 61298-2 Project Dashboard . The is finalizing IEC 61298-2 Edition 3

The rollout of these standards is phased, with the previous 2008 versions remaining active until the final publication of each part: IEC 61298-2:2008
