This document defines a conceptual schema for observations, for features involved in the observation process, and for features involved in sampling when making observations. These provide models for the exchange of information describing observation acts and their results, both within and between different scientific and technical communities.
Observations commonly involve sampling of an ultimate feature-of-interest. This document defines a common set of sample types according to their spatial, material (for ex situ observations) or statistical nature. The schema includes relationships between sample features (sub-sampling, derived samples).
This document concerns only externally visible interfaces and places no restriction on the underlying implementations other than what is needed to satisfy the interface specifications in the actual situation.

This document specifies requirements and recommendations for performance assessment methods for superhydrophobic surfaces and coatings subjected to mechanical stress, solar radiation and weathering, liquids, and thermal cycling, where applicable, based on the agreement between interested parties. The performance assessment is carried out based on comparative measurements of the advancing and receding angles and the calculation of the contact angle hysteresis before and after the above-mentioned working/environmental conditions. This document does not address safety and environmental related issues of such coatings. This document is applicable to any superhydrophobic surfaces and coatings (i.e. nanostructured) on which the measurement of the advancing and receding angles is possible.

This document specifies acceptable criteria for microbiological cleanliness and adequacy of preservation of the specified toy materials. The requirements in this document apply to all toys that are, contain or are supplied with aqueous materials (e.g. paste, putty, liquid or gel). In addition, this document applies to toys that are or include a cosmetic (including those intended for use on a toy as well as on the child). Powders and similar substances intended to be mixed with water are also within the scope of this document. The cleanliness and preservation effectiveness requirements are applicable to a toy as it is initially received by the consumer in an unopened and undamaged container and do not apply after a toy is subjected to reasonably foreseeable conditions of normal use and abuse, unless specifically noted otherwise. The microbial limits and test methods contained in this document are inappropriate to apply to products that are consumer complaint returns, as there is no way to establish what conditions the toys have been subject to before being returned. The following are excluded from the scope of this document: — materials that are inaccessible during normal use or reasonably foreseeable abuse; — powder or powder-like materials intended to show biological phenomena, e.g. shrimp eggs, seeds, soil; — food.

IEC TS 62607-6-8:2023 establishes a method to determine the key control characteristic sheet resistance RS [measured in ohm per square (Ω/sq)], by the in-line four-point probe method, 4PP.
The sheet resistance RS is derived by measurements of four-terminal electrical resistance performed on four electrodes placed on the surface of the planar sample.
The measurement range for RS of the graphene samples with the method described in this document goes from 10−2 Ω/sq to 104 Ω/sq.
The method is applicable for CVD graphene provided it is transferred to quartz substrates or other insulating materials (quartz, SiO2 on Si, as well as graphene grown from silicon carbide.
The method is complementary to the van der Pauw method (IEC 62607-6-7) for what concerns the measurement of the sheet resistance and can be useful when it is not possible to reliably place contacts on the sample boundary.

IEC TS 62607-6-7:2023 establishes a method to determine the key control characteristics sheet resistance RS [measured in ohm per square (Ω/sq)], by the van der Pauw method, vdP.
The sheet resistance RS is derived by measurements of four-terminal electrical resistance performed on four electrical contacts placed on the boundary of the planar sample and calculated with a mathematical expression involving the two resistance measurements.
The measurement range for RS of the graphene samples with the method described in this document goes from 10−2 Ω/sq to 104 Ω/sq.
The method is applicable for CVD graphene provided it is transferred to quartz substrates or other insulating materials (quartz, SiO2 on Si), as well as graphene grown from silicon carbide.
The method is complementary to the in-line four-point-probe method (4PP, IEC 62607-6-8) for what concerns the measurement of the sheet resistance and can be applied when it is possible to reliably place contacts on the sample boundary, avoiding the sample being scratched by the 4PP.
The outcome of the van der Pauw method is independent of the contact position provided the sample is uniform, which is typically not true for graphene at this stage. This document considers the case of samples with non-strictly uniform conductivity distribution and suggests a way to consider the sample inhomogeneity as a component of the uncertainty on RS.

IEC TS 62607-6-17:2023 establishes a standardized method to determine the key control characteristic order parameter for graphene-based material and layered carbon material by X-ray diffraction (XRD) and transmission electron microscopy.
The order parameter is analysed from two perspectives: z-axis and x-y-axis. In the z-axis the order parameter is derived from the full width at half maximum (FWHM) of peak (002) in the XRD spectrum. In the x-y-axis, it is derived from the FWHM of peak (100) corresponding to diffraction patterns obtained by SAED (selected area electron diffraction) technique, which is routinely performed on most transmission electron microscopes in the world.
The method is applicable for graphene-based material and layered carbon material including graphite, expanded graphite, amorphous carbon, vitreous carbon or glassy carbon, the structures of which are clarified by other characterization techniques.
The method is applicable for differentiating few-layer graphene or reduced graphene oxide from layered carbon material.
Typical application area is quality control in manufacturing to ensure batch-to-batch reproducibility.
NOTE Graphene oxide, one type of graphene-based material, is not within the scope of this document.

This standard specifies the conceptual and logical data model and physical encoding formats for geographic databases for Intelligent Transport Systems (ITS) applications and services. It includes a specification of potential contents of such databases (data dictionaries for Features, Attributes and Relationships), a specification of how these contents shall be represented, and of how relevant information about the database itself can be specified (metadata).
The focus of this standard is on ITS applications and services and it emphasizes road and road-related information. ITS applications and services, however, also require information in addition to road and road-related information.
Typical ITS applications and services targeted by this International Standard are in-vehicle or portable navigation systems, traffic management centres, or services linked with road management systems, including public transport systems.
The Conceptual Data Model has a broader focus than ITS applications and services. It is application-independent, allowing for future harmonization of this standard with other geographic database standards.
In order to deal with a multiple data provider environment and new applications, conceptual models, features, attributes and relationships are expanded in GDF5.1.
GDF5.1 is separated into two parts according to methods of utilization.
GDF5.1 Part 1 defines application-independent map data shared between multiple sources.
GDF5.1 Part 2 defines map data used in automated driving systems, cooperative ITS, and multi-modal transport.
