A common language for standards, disclosed to a wide audience and referring only to the operational protocols and to their outcomes, is needed both for a consistent set of standards and the connection with the scientific literature. This glossary will take into account existing glossary of terms used in photocatalysis and photochemistry. Because in photocatalysis numerous properties are difficult to be evaluated, it is strongly recommended in standard norms to avoid reporting properties depending on number of actives sites, the mechanisms of adsorption or kinetic mechanisms of photocatalytic reactions. For the same reason instead of the quantum yield and related quantities it is easier to report the photonic efficiency.

Most of the definitions reported in this document are a sub-set of the IUPAC definitions in photocatalysis and radiocatalysis [1]. Some other definitions, in particular for the photocatalytic rate and reactors are taken from a dedicated work [2]. The use and many technical specifications on the physical values suggested for irradiation conditions in the standards are reported in a separate Technical Specification [3].

The arrangement of entries is alphabetical, and the criterion adopted by the IUPAC has been followed for the typeface used: italicized words in a definition or following it indicate a cross-reference in the Glossary.

This document gives guidance on levels of imperfections in electron and laser beam welded joints in aluminium and its alloys. Three levels are given in such a way as to permit application for a wide range of welded fabrications. The levels refer to production quality and not to the fitness-for-purpose of the product manufactured.

This document applies to electron and laser beam welding of:

— aluminium and its alloys;

— magnesium and its alloys;

— pure copper (e.g. Cu-ETP1 CW003A, Cu-ETP CW004A, Cu-FRHC CW005A, Cu-FRTP CW006A, Cu-OF1 CW007A, Cu-OF CW008A, Cu-OFE CW009A, Cu-PHC CW020A, Cu-HCP CW021A, Cu-PHCE CW022A, Cu-DLP CW023A, Cu-DHP CW024A);

— all types of welds welded with or without additional filler wire;

— materials equal to or above 0,5 mm thickness for electron and laser beam welding.

When significant deviations from the joint geometries and dimensions stated in this standard are present in the welded product, it is necessary to evaluate to what extent the provisions of this standard can apply.

NOTE 1 For circular welds, a lower quality level e.g., may be specified for the fade-out zone.

Metallurgical aspects, e.g. grain size, hardness, hydrogen embrittlement (pure copper) are not covered by this standard.

This document specifies a method for the measurement of metal coating thickness by first forming a step between the surface of the coating and the surface of its substrate and then measuring the step height using a profile recording instrument. It covers the instrumentation characteristics and the procedure appropriate to this specific application of profilometric methods.

The method is applicable to the measurement of thicknesses of metal coatings from 0,01 μm to 1 000 μm on flat surfaces and, if appropriate precautions are taken, on cylindrical surfaces. It is highly suitable for the measurement of minute thicknesses but, for thicknesses of less than 0,01 μm, surface flatness and surface smoothness are very critical and accordingly, the method is not recommended for use down to the lowest level of measurement usual for electronic stylus instruments. The method is suitable for measuring coating thicknesses when preparing coating thickness reference standards.

This International Standard specifies spectroscopic ellipsometry (SE) for determination of optical properties (refractive index n and extinction coefficient k) and the optical classification of different types of amorphous carbon films within the n-k plane.

Amorphous carbon films may be deposited by ionized evaporation, sputtering, arc deposition, plasma-assisted chemical vapour deposition, hot filament techniques and others. Amorphous carbon films have an amorphous structure, containing both sp2 and sp3 bonded carbon, and contain in some cases also hydrogen. There is graphite-like carbon as well as polymer-like, glass-like and diamond-like carbon films. Carbon films modified with metals, silicon and amorphous carbon films that have a gradient of composition/property in the thickness are not included. Paints and Varnishes are not included.

As amorphous carbon films show a huge diversity of structure and properties, it is indispensable to select the appropriate type of amorphous carbon film to exploit their excellent properties in practical use. Therefore, carbon films are characterized by spectroscopic ellipsometry under reasonable conditions. This enables classification of amorphous carbon films on silicon wafers within the n-k plane acting as process fingerprint.

This document specifies requirements that can be checked by computer for the exchange, between organizations and systems, of master data that consists of characteristic data.

EXAMPLE 1 This document applies to a message that a supplier sends to a customer. The message contains characteristic data describing an item that the customer is considering buying.

EXAMPLE 2 This document does not apply to a credit charge transaction sent from a merchant to a credit card company because the data sent is not master data.

EXAMPLE 3 This document does not apply to the contents of a company's internal supplier master when these contents are not being exchanged between organizations or systems.

NOTE 1 "Organization" does not necessarily mean a company or corporation. Sometimes it could be a subdivision or branch that covers some distinct area of business operation. Different business units of a company exchanging master data, or a business unit exchanging master data with headquarters, can be considered separate organizations for the purposes of this document.

The following are within the scope of this document:

— conformance of master data messages to a formal syntax;

— semantic encoding of master data messages;

— conformance of master data messages to data specifications;

— commercial models for master data exchanges.

The following are outside the scope of this document:

— master data that is not characteristic data;

— data that is not in messages;

— messages that are not used to exchange master data between organizations or systems;

— recording the history of master data;

NOTE 2 "Data provenance record" is the common name for a record of the history of the origination, modification and transfer of custody or ownership of data.

— accuracy of master data;

— exchange of data that is not master data;

— management of master data internally within an organization;

EXAMPLE 4 Data within an organization's enterprise resource planning or product data management system is out of scope.

EXAMPLE 5 Making backup copies of data files containing master data is out of scope.

— quality of data dictionaries;

— a specific formal syntax for the exchange of master data.

EXAMPLE 6 ISO 9735, ISO 13584, ISO 15926 and ISO 22745 specify formats that can be used to exchange master data.

NOTE 3 ISO 13584, ISO 15926 and ISO 22745 can also be used to exchange data dictionaries but the requirements for the exchange of data dictionaries are out of scope of this document.

The requirements in this document are considered necessary but not sufficient to achieve data quality with respect to exchange of master data. Issues such as the accuracy and provenance of master data also need to be addressed as part of an overall data quality strategy.

NOTE 4 The following parts of ISO 8000 address such issues:

— ISO 8000-120 addresses provenance;

— ISO 8000-130 addresses accuracy;

— ISO 8000-140 addresses completeness.
