ISO 16659 series provide different test methods aiming at assessing the performances of radioactive iodine traps in ventilation systems of nuclear facilities. This series deals with iodine traps with solid sorbent, mainly activated and impregnated charcoal, the most common solid sorbents used in ventilation systems of nuclear facilities, as well as other sorbents for special conditions (e.g. high temperature zeolites). ISO 16659-1 provides the general requirements to be applied for all methods of the series. The scope of this document is to provide general and generic requirements for the test method using cyclohexane (C6H12) as a tracer to determine the mechanical leakage rate of iodine trap. This reproducible method can support nuclear operators to compare the result with reference values given in safety reports. Unlike the method of radioactive methyl iodide described in ISO 16659-2, the cyclohexane field test method covered in this document does not directly give a decontamination factor for the iodine trap, but only the iodine trap performance information of an integrity test. Due to the use of the environmentally friendly test reagent of low-toxicity in the field tests, the method is mainly suitable for ventilation systems of those habitable spaces (e.g. main control rooms of nuclear power plants), and performance test of a single iodine trap before its delivery and acceptance. In addition, the method can also be used for iodine traps with activated carbon sampling canister (e.g. deep bed iodine trap Type III and Drawer iodine trap Type II).

This document defines and describes the concept of on-boarding of person identification data (PID) within a Wallet. The scope of this document includes cases where a natural person is the User in control of a Wallet. This includes a natural person who is in control of their own information, as well as natural persons who control information to represent another natural person or a legal person. This document considers a single set of PID attributes linked to a single Wallet Unit. This does not exclude the issuance of multiple PIDs representing the same set of PID attributes, e.g. batch issuance.
It also provides the general workflow, the roles and responsibilities at stake, and links the on-boarding with the Level of Assurance concept underpinning eIDAS [1];
The scope of this document includes cases where a natural person is the User in control of a wallet. This includes a natural person who is in control of their own data as well as natural persons who control data to represent another natural person or legal person.
EXAMPLE     If a natural person represents a legal person, the PID provider can issue a "representation PID" in an own Wallet Unit for representation purposes controlled by the natural person Wallet User. The "representation PID" is a kind of attestation which contains PID about the natural person (representative) and about the legal person (representee).
This document is limited to the on-boarding of an unique set of person identification data, complying with the legal provisions of eIDAS [1], in particular (1) issued in accordance with Union or National laws, and (2) conformant with the relevant implementing act [5].

a) The externally visible services provided by the WiTSnet in terms of:
1) an abstract model for defining application resources (objects) capable of being manipulated by users via the use of the FAL services;
2) the primitive actions and events of the services;
3) the parameters associated with each primitive action and event, and the form which they take;
4) the interrelationship between these actions and events, and their valid sequences.
b) The externally visible behavior provided by the WiTSnet in terms of:
1) the abstract syntax defining the data-link layer and application layer protocol data units conveyed between communicating data-link and application entities;
2) the transfer syntax defining encoding rules that are applied to the data-link layer and the application layer protocol data units;
3) the data-link and the application context state machines defining the data-link and the application service behaviors visible between communicating data-link and application entities; and

This document specifies general methods, with suitable test conditions, for the determination of the ash of a range of plastics. The particular conditions chosen can be included in the specifications for the plastic material in question.
Particular conditions applicable to poly(alkylene terephthalate) materials, unplasticized cellulose acetate, polyamides and poly(vinyl chloride) plastics, including some specific filled, glass-fibre-reinforced and flame-retarded materials, are specified in ISO 3451-2, ISO 3451-3, ISO 3451-4 and ISO 3451-5.

This document is directly applicable to pulsed X-radiation with pulse duration of 0,1 ms up to 10 s. This range covers the whole range used in medical diagnostics at the time of publication. Some specifications can also be applicable for much shorter pulses; one example is the air kerma of one pulse. Such a pulse can be produced, e.g. by X-ray flash units or high-intensity femtosecond-lasers. Other specifications are not applicable for much shorter pulses; one example is the time-dependent behaviour of the air kerma rate. This cannot be measurable for technical reasons as no suitable instrument is available, e.g. for pulses produced by a femtosecond-laser.
This document specifies the characteristics of reference pulsed radiation for calibrating and testing radiation protection dosemeters and dose rate meters with respect to their response to pulsed radiation. At this point, it is only concerned with the characteristics of single pulses. Single pulses are the most difficult for dosemeters to measure. Determining the dose for repeated pulses is easier, but still more difficult than for continuous radiation, i.e. the performance of the dosemeters when measuring repeated pulses lies between these extremes. The radiation characteristics includes the following:
time-dependent behaviour of the air kerma rate of the pulse;
time-dependent behaviour of the X-ray tube high voltage during the pulse;
uniformity of the air kerma rate within a cross-sectional area of the radiation beam;
air kerma of one radiation pulse;
air kerma rate of the radiation pulse;
repetition frequency.
This document does not define new radiation qualities but uses those radiation qualities specified in existing ISO and IEC standards. Instead, this document gives the link between the parameters for pulsed radiation and the parameters for continuous radiation specifying the radiation qualities. It does not specify specific values or series of values for the pulsed radiation field but specifies only those limits for the relevant pulsed radiation parameters that are required for calibrating dosemeters and dose rate meters and for determining their response depending on the said parameters.
The pulse parameters with respect to the phantom-related quantities were determined using conversion coefficients according to ISO 4037 (all parts). This is possible as the radiation qualities specified in existing ISO and IEC standards are used.
A given reference pulsed X-ray facility is characterized by the parameter ranges over which the full specifications and requirements according to this document are met. Therefore, not all reference pulsed X-ray facilities can produce pulses covering the same parameter ranges.

IEC TR 63439-1-2:2026 specifies a comprehensive study of the robotic technologies in power systems, including generation, transmission, and distribution. The primary objectives are:
a) System overview and classification
Analyze current robotic applications across all power system segments (generation, transmission, and distribution), developing a comprehensive classification framework that categorizes robots by operational scenarios (substations, power lines), functional roles (inspection, repair), and environmental conditions (high-voltage zones, confined spaces).
b) Core technology assessment
Evaluate fundamental robotic technologies encompassing mobility platforms (ground robots, drones, remotely operated vehicles (ROVs), navigation systems (GPS, LiDAR, vision-based), and communication networks (wired/wireless/hybrid); assess functional capabilities through multi-sensor inspection (visual, thermal, ultrasonic) and maintenance operations (live-line work, cleaning, debris removal), and examine integration aspects with power grid management systems including data protocols and cybersecurity requirements.
c) Testing and validation framework
Establish performance benchmarks for core robotic functions including autonomous navigation, inspection accuracy, and operational efficiency, while developing reliability testing methods that incorporate failure mode analysis (FMEA/FMECA) and environmental stress testing under extreme conditions.
d) Standardization roadmap
Conduct a gap analysis of current power robotics standards (including IEC/TC129) to identify deficiencies, while systematically mapping stakeholder requirements to prioritize standardization needs across hardware, software interfaces, and safety protocols; develop the roadmap with clear timelines for creating new standards, facilitating adoption, and ensuring compliance verification across the industry.
