IEC TS 62607-9-2:2024, which is a Technical Specification, establishes a standardized method to determine the key control characteristic
• magnetic field distribution
of nanomagnetic materials, structures and devices by the
• magneto-optical indicator film technique.
The magnetic field distribution is derived by utilizing a magneto optical indicator film, which is a thin film of magneto-optic material that is placed on the surface of an object exhibiting a spatially varying magnetic field distribution. The Faraday effect is then employed to measure the magnetic field strength by analysing the rotation of the polarization plane of light passing through the magneto-optic film.
The method is applicable for measuring the stray field distribution of flat nanomagnetic materials, structures and devices.
- The method can especially be used to perform fast quantitative measurements of stray field distributions at the surface of an object.
- The magneto-optic indicator film technique (MOIF) is a fast, non-destructive method, making it an attractive option for materials analysis and testing in the industry.
- MOIF measurements can be done without any sample preparation and do not rely on specific surface properties of the object. It can be applied to the characterization of rough samples as well as of samples with non-magnetic cover layers.
- MOIF can quantitatively measure magnetic field distributions:
• with a one-shot measurement which typically takes a few seconds
• over areas of several square centimetres (over diameters of up to 15 cm with special techniques)
• in a field range from 1 mT to more than 100 mT
• with down to 1 µm spatial resolution
- Although techniques with nano-scale resolution are suitable for analysing the details of magnetic field structure, their ability to characterize larger areas is limited by their scanning area. Therefore, the MOIF technique is an indispensable complementary method that can offer a more comprehensive understanding of material properties.
This document focuses on the calibration procedures, calibrated measurement process, and evaluation of measurement uncertainty to ensure the traceability of quantitative magnetic field measurements obtained through the magneto-optic indicator film technique.

This document specifies the evaluation methods for hydrogen content in ultrafine bubble (UFB) dispersions. The titration (oxidimetry) method can be used as a quick method to estimate the hydrogen content in hydrogen UFB dispersions. The lower limit of detection is 0,1 mg/l, and the range with acceptable accuracy is between 0,2 mg/l and 1,6 mg/l. The existence of oxidizing or reducing substances in dispersions influences measurement accuracy. The gas chromatographic method features a considerably high accuracy range and lower limit of detection. The existence of UFBs in water does not influence the measurement results. The existence of oxidizing or reducing substances in water does not affect the measurement accuracy either. However, the measurement procedure is time consuming. NOTE This document only provides a method for determining hydrogen contents in UFB dispersions and does not involve the specific effects of hydrogen UFB dispersion application.

IEC TS 62607-6-12:2024 establishes a standardized method to determine the key control characteristic
- number of layers
for films consisting of graphene by
- Raman spectroscopy and
- optical reflection.
Criteria for the determination of the number of layers are the G-peak integrated intensity and the optical contrast. Both methods enable to distinguish between graphene and multilayer graphene. However, neither method on its own nor the combination of the two enable a determination of the number of layers in all possible cases (especially regarding all possible stacking angles). But the comparison of the values deduced by each method allows to discriminate whether the determined number of layers is correct and can be specified or not.
- The method is applicable to exfoliated graphene and graphene grown on or transferred to a substrate with a small defect density, low surface contamination (e.g. transfer residue) and number of layers up to 5.
- The method is suitable for the following substrates:
a) glass (soda lime glass or similar with a refractive index between 1,45 and 1,55 at 532 nm);
b) oxidized silicon (SiO2 on silicon, with a SiO2 thickness of 90 nm ± 5 nm).
- The spatial resolution is in the order of 1 µm given by the spot size of the exciting laser.

This document:
— defines a reference Land Administration Domain Model (LADM) covering basic information-related components of land administration/georegulation;
— provides an abstract, conceptual model with packages related to:
— parties (people and organizations),
— basic administrative units, rights, responsibilities and restrictions (RRRs),
— spatial units,
— a generic conceptual model (sources and versioned object);
— provides terminology for land administration/georegulation, based on various national and international systems, that is as simple as possible in order to be useful in practice. The terminology allows a shared description of different formal or informal practices and procedures in various jurisdictions;
— provides a content model independent of encoding, allowing for the support of various encodings;
— provides a basis for national and regional profiles;
— enables the combining of land administration/georegulation information from different sources in a coherent manner.
The following are outside the scope of this document:
— interference with (national) land administration/georegulation laws with potentially legal implications due to the possibility of describing different types of systems but in the same notation;
— construction of external databases with party data, address data, land cover data, physical utility network data, archive data and taxation data. However, the LADM provides stereotype classes for these data sets to indicate which data set elements the LADM expects from these external sources, if available.
This document provides the concepts and basic structure for standardization in the land administration/georegulation domain. It defines a general schema that permits regulatory information to be described. It also allows for the relationship to multiple parties and groups to be expressed together with a referencing structure so that sourcing of all information systems can be maintained. This document establishes the common elements and basic schema upon which more detailed schema can be established.

This document specifies the detection of Clostridium (C.) perfringens.
This document is applicable to:
— products intended for human consumption;
— products intended for animal feeding;
— environmental samples in the area of food and feed production and handling;
— samples from the primary production stage.
This horizontal method was originally developed for the examination of all samples belonging to the food chain. Based on the information available at the time of publication of this document, this method is considered to be fully suited to the examination of all samples belonging to the food chain. However, because of the large variety of products in the food chain, it is possible that this horizontal method is not appropriate in every detail for all products. Nevertheless, it is expected that the required modifications are minimized so that they do not result in a significant deviation from this horizontal method.
NOTE Interlaboratory studies with a small number of participating laboratories (<10) were conducted for the following food categories:
— ready-to-eat, ready-to-reheat meat products;
— eggs and egg products (derivates);
— ready-to-eat, ready-to-reheat fishery products;
— processed fruits and vegetables;
— infant formula and infant cereals (with probiotics);
— multi-component foods or meal components.
It has also been validated with a small number of participating laboratories for the following other category:
— environmental samples (food or feed production).
Since the method is not commonly used for samples in the primary production stage, this category was not included in the interlaboratory study. Therefore, no performance characteristics were obtained for this category. The method has not been validated for the category ‘pet food and animal feed’, as the test samples used for the interlaboratory study were already naturally contaminated with C. perfringens. Given the limited number of participating laboratories in the interlaboratory studies, the calculated performance characteristics can be used as indicative values of the method performance. For detailed information on the validation, see Clause 11 and Annexes C to F.

This document specifies evaluation methods for the oxygen content in fine bubble dispersion in water. Three test methods which are adopted include the optical sensor, the electrochemical probe and the iodometric method. The first two methods have an advantage in availability of in situ and real-time measurement, and high accessibility to commercially available instruments. The last one, composed of a well-established chemical analysis procedure, is advantageous in the situation where the instruments to be used in the first two methods are unavailable. The detection limits of the electrochemical and optical sensor methods are stated in the instruction manuals of the instruments, in most cases 0,1 mg/l or 0,2 mg/l. The upper limit depends on the specification of the instrument used. Most instruments allow measurement of a supersaturated sample. Measurement range of the iodometric method is between 0,2 mg/l and 20 mg/l. NOTE Chemical analysis methods other than the iodometric method can be applied[1] as an alternative.

IEC TS 62607-6-4:2024 has been prepared by IEC technical committee 113: Nanotechnology for electrotechnical products and systems. It is a Technical Specification.
This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) changed the document title to better reflect its purpose and application:
old title: Graphene – Surface conductance measurement using resonant cavity
new title: Graphene based materials – Surface conductance: non-contact microwave resonant cavity method.
b) replaced former Figure 1 with new Figure 1 and Figure 2, to better illustrate the method’s fundamentals and its implementation for a non-technical reader.
This part of IEC 62607 establishes a standardized method to determine the key control characteristic
a) surface conductance
for films of graphene and graphene-based materials by the
b) non-contact microwave resonant cavity method
The non-contact microwave resonant cavity method monitors the microwave resonant frequency shifts and changes in the cavity’s quality factor during the insertion of the specimen into the microwave cavity, as a function of the specimen surface area. The empty cavity is an air-filled standard R100 rectangular waveguide operated at one of the resonant frequency modes, typically at 7,5 GHz [4].
1) The method is applicable for graphene materials which are synthesized by chemical vapour deposition (CVD) on metal substrates, epitaxial growth on silicon carbide (SiC), obtained from reduced graphene oxide (rGO), or mechanically exfoliated from graphite [5].
2) This measurement does not explicitly depend on the thickness of the nano-carbon layer. The thickness of the specimen does not need to be known, but it is assumed that the lateral dimensions are uniform over the specimen area.
NOTE In some countries, the R100 standard waveguide is referenced as WR-90.

This document specifies the enumeration of Clostridium (C.) perfringens by colony-count technique.
This document is applicable to:
— products intended for human consumption;
— products for feeding animals;
— environmental samples in the area of food and feed production and handling;
— samples from the primary production stage.
NOTE This method has been validated in an interlaboratory study for the following food categories:
— ready-to-eat, ready-to-reheat meat products;
— eggs and egg products (derivates);
— processed fruits and vegetables;
— infant formula and infant cereals;
— multi-component foods or meal components.
It has also been validated for the following other categories:
— pet food and animal feed;
— environmental samples (food or feed production).
As this method has been validated for at least five food categories, this method is applicable for a broad range of
food. For detailed information on the validation, see Clause 11 and Annex C. Since the method is not commonly
used for samples in the primary production stage, this category was not included in the interlaboratory study.
Therefore, no performance characteristics were obtained for this category.
This horizontal method was originally developed for the examination of all samples belonging to the
food chain. Based on the information available at the time of publication of this document, this method
is considered to be fully suited to the examination of all samples belonging to the food chain. However, because of the large variety of products in the food chain, it is possible that this horizontal method is not
appropriate in every detail for all products. Nevertheless, it is expected that the required modifications
are minimized so that they do not result in a significant deviation from this horizontal method.
This technique is suitable for, but not limited to, the enumeration of microorganisms in test samples
with a minimum of 10 colonies counted on a plate. This corresponds to a level of contamination that is
expected to be higher than 10 cfu/ml for liquid samples or higher than 100 cfu/g for solid samples.

It has also been validated for the following other categories:
— pet food and animal feed;
— environmental samples (food or feed production).
As this method has been validated for at least five food categories, this method is applicable for a broad range of food. For detailed information on the validation, see Clause 11 and Annex C. Since the method is not commonly used for samples in the primary production stage, this category was not included in the interlaboratory study. Therefore, no performance characteristics were obtained for this category.
This horizontal method was originally developed for the examination of all samples belonging to the food chain. Based on the information available at the time of publication of this document, this method is considered to be fully suited to the examination of all samples belonging to the food chain. However, because of the large variety of products in the food chain, it is possible that this horizontal method is not appropriate in every detail for all products. Nevertheless, it is expected that the required modifications are minimized so that they do not result in a significant deviation from this horizontal method.
This technique is suitable for, but not limited to, the enumeration of microorganisms in test samples with a minimum of 10 colonies counted on a plate. This corresponds to a level of contamination that is expected to be higher than 10 cfu/ml for liquid samples or higher than 100 cfu/g for solid samples.
