IEC TS 63222-3:2024 is intended to provide provisions regarding recognized engineering practices applicable to assess the user’s characteristics in power quality predicted assessment. It summarizes the best practice in non-linear, unbalanced, impact and fluctuating loads or generations modelling for power quality disturbance anticipation in public power systems at the planning stage.
This document focuses on frequency-domain modelling for AC power quality analysis in electric power networks, typically in the range up to the 50th harmonic (2,5 kHz in 50 Hz systems or 3 kHz in 60 Hz systems). Unbalance is analyzed in three-phase systems and only negative sequence component is considered. The approach and modelling guidelines provided are valid on the representation of user installations connected to power systems acting as sources of disturbance. Modelling of the network elements is out of the scope of the document.
These guidelines will be valuable in the definition of power quality performance specifications for user equipment. They will also assist users when modelling their installation to assess or demonstrate compliance with the emission limits provided by the system owner/operator and to investigate and specify mitigation measures.

This part of IEC 60068 provides the necessary information and the basic principles of the effect
of humidity in the context of environmental testing to assist in preparing relevant specifications,
such as standards for components or equipment. Furthermore, information is provided on
operating climatic test chambers.
The object of this document is to present supporting documentation and guidance for a range
of damp heat tests which, when specified by the relevant specification, can be applied to
demonstrate the performance of equipment for which damp heat testing is required with the
main aim of achieving qualification. This information and basic principles are intended to help
selecting appropriate tests and test severities for specific products and, in some cases, specific
types of application.
The object of damp heat tests is to determine the ability of products to withstand the stresses
occurring in a high relative humidity environment, with or without condensation, and with special
regard to variations of electrical and mechanical characteristics. Damp heat tests can also be
utilized to check the resistance of a specimen to some forms of corrosion attack.

This part of IEC 62321 specifies two different techniques for the determination of
tris(2-chloroethyl) phosphate (TCEP) in plastics, the GC-MS or LC-MS method, both of which
are applicable to quantitative analysis.
These two techniques are applicable to use with polyurethane, polyvinylchloride, and
polyethylene materials containing TCEP between 200 mg/kg to 2 000 mg/kg.
These test methods do not apply to plastic materials having a processing temperature higher
than 230 °C.
GC-MS using a pyrolyser/thermal desorption accessory (Py/TD-GC-MS) technique is described
in Annex A and can be used for the screening of TCEP in plastics.
NOTE TCEP starts thermal decomposition at approximately 230 °C. Polymer types that have a processing
temperature into shapes of plastics (e.g. pellets, moulded parts or sheets) not exceeding the decomposition
temperature can contain TCEP.

IEC TR 63401-3:2023, which is a Technical Report, provides an insight into the various forms of fast frequency response and frequency ride-through techniques that involve inverter-based generation sources (mainly wind and PV) in a bulk electrical system.
This document first focuses on extracting the clear definition of FFR from different references around the world, while studying the mechanism of FFR acting on system frequency and the unique features of FFR. It then compares various kinds of frequency response and demonstrates the relationship among synchronous inertia response, fast frequency response, and primary frequency response. Several system needs and conditions where FFR is suitable are identified. This document also focuses on the performance objectives, practicality and capabilities of various non-synchronous resources, and discusses the test methods for verifying FFR capability at different levels. Finally, it focuses on the ROCOF issues and on the robust performances of FFR. .

IEC TS 63222-2:2023 defines technical requirements for designing a power quality monitoring system for public power supply networks. It is applicable for LV, MV and HV public power supply networks.
The design procedure of a power quality monitoring system (PQMS) generally includes the following four steps:
• Step 1: purpose and application analysis: Analyse power quality monitoring (PQM) demand and define the purpose of PQM.
• Step 2: preliminary study: Collect background information such as network configuration, the parameters of instrument transformers, e.g. the output levels and performance capabilities, attributes of loads or distributed generations (DG), communication conditions, budgets, and other restrictive conditions, and select the parameters to be monitored and monitoring sites according to corresponding principles.
• Step 3: system structure design: Design the overall structure of the monitoring system according to the monitoring purpose based on the analysis of the advantages and disadvantages of various system structures.
• Step 4: detailed design of functional modules: Design the function modules of data collection, communication, data storage, data processing and analysis in detail according to the functional requirements.
This document defines the main purposes of PQM and gives recommendations for preliminary study, such as how to select monitoring sites and monitoring parameters and whether the instrument transformer is suitable for monitoring. This document also classifies the PQMS structure and specifies the functional requirements of the modules such as data collection, communication, data storage, data processing and analysis.

IEC 63345:2023 specifies a data model to abstract the metering world towards a simple external consumer display. The data model, as described by means of functional blocks contained in this document, lays down the format of metering data accessible by a simple external consumer display. This data interface would be typically part of the meter communication functions and be accessed by a simple external consumer display via the H1 interface of CEN/CLC/ETSI TR 50572 between the display and the meter communication functions.
