This document defines and specifies requirements for purchased parts made by additive manufacturing.

It gives guidelines for the elements to be exchanged between the customer and the part provider at the time of the order, including the customer order information, part definition data, feedstock requirements, final part characteristics and properties, inspection requirements and part acceptance methods.

It is applicable for use as a basis to obtain parts made by additive manufacturing that meet minimum acceptance requirements. More stringent part requirements can be specified through the addition of one or more supplementary requirements at the time of the order.

This document specifies the application of the phased array technology for the semi- or fully automated ultrasonic testing of fusion-welded joints in metallic materials of minimum thickness 6 mm. It applies to full penetration welded joints of simple geometry in plates, pipes, and vessels, where both the weld and the parent material are low-alloyed carbon steel.

Where material-dependent ultrasonic parameters are specified in this document, they are based on steels having a sound velocity of (5 920 ± 50) m/s for longitudinal waves, and (3 255 ± 30) m/s for transverse waves. It is necessary to take this fact into account when testing materials with different velocities. Steels with other velocities should be tested under testing level D.

For coarse-grained or austenitic steels ISO 22825 applies.

This document provides guidance on the specific capabilities and limitations of the phased array technology for the detection, location, sizing and characterization of discontinuities in fusion-welded joints. Phased array technology can be used as a stand-alone technology or in combination with other non-destructive testing (NDT) methods or techniques, for manufacturing inspection, pre-service and forin-service inspection.

This document specifies four testing levels, each corresponding to a different probability of detection of imperfections.

This document permits assessment of discontinuites for acceptance purposes based on either amplitude (equivalent reflector size) and length or on height and length.

This document does not include acceptance levels for discontinuities.

This document is not applicable for automated testing of welds during the production of steel products covered by ISO 10893-8, ISO 10893-11 and ISO 3183.

The document specifies, with reference to ISO 230-1 and ISO 230-2, geometric tests, machining tests and tests for accuracy and repeatability of positioning axes on general purpose and normal accuracy manually and numerically controlled (NC) external cylindrical centreless grinding machines. It also specifies the applicable tolerances corresponding to the above-mentioned tests.

This document deals only with the verification of accuracy of the machine. It does not apply to the testing of the machine operation (vibrations, abnormal noise, stick-slip motion of components, etc.) nor to machine characteristics (such as speeds, feeds, etc.), which should generally be checked before testing of machine accuracy.

This document provides the terminology used for the principal components of the machine and the designation of the axes with reference to ISO 841.

NOTE In addition to the terms used in the official ISO languages (English and French), this document gives the equivalent terms in the German, Italian, Japanese, and Persian languages; these are published under the responsibility of the national member bodies for Germany (DIN), Italy(UNI), Japan (JIS), and Iran (ISIRI). However, only the terms given in the official languages can be considered as ISO terms.

This International Standard deals with diamond tools whose cutting edges are made of CVD diamond, either as a solid single piece or as a coating. The tool specifications are differentiated into CVD diamond-coated tools (CVD diamond thin-film coatings) and tools with a CVD diamond cutting insert. According to ISO 513, CVD diamond tools can be classified under "hard coatings of hard metal and ceramic" and "binder-free polycrystalline diamond". In order to differentiate the CVD diamond tools from tools with monocrystalline synthetic or natural diamond (MCD or monocrystalline diamond) or with sintered diamond with a binder phase (PCD or polycrystalline diamond), the structure and characteristics of MCD and PCD tools with binder phase are also briefly described.

This document defines welding positions for testing and production, for butt and fillet welds, in all product forms.

Annex A gives examples of the limits of the slope of a weld axis and the rotation of the weld face about the weld axis for welding positions in production welds.

Annex B gives a comparison of International, European and US designations for welding positions.

This part of ISO 10303 specifies the use of the integrated resources necessary for the scope and information requirements for the representation of engineering property data that are used for product design, product validation and other purposes.

NOTE 1 The application activity model in Annex F provides a graphical representation of the processes and information flows that are the basis for the definition of the scope of this part of ISO 10303.

The following are within the scope of this part of ISO 10303:
-   descriptions and definitions of the manufactured product, the sample of the product and the testable version of the sample;

-   description of the composition and substance of the product;

-   description of the processes used in the measurement;

-   descriptions of the data values produced by the measurement, with the specification of the conditions in which the data is valid;

-   references to standards and other documents wherein sampling, measurement and other details of testing and measurement processes can be specified or described;

-   descriptions and qualifications of the personnel and or organizations responsible for the measurement;

-   specification of the requirements, conditions and tolerances to be satisfied in the measurement and a description of the outcome;

This document gives guidelines for determining the average surface density over a measured area of anodic oxide or of a coating deposited autocatalytically, mechanically, by chemical conversion, by electrodeposition, by hot dip galvanizing and by chemical or physical vapour deposition using gravimetric and other chemical analysis procedures that have attained some degree of national or international standardization.

A variety of procedures are described and include:

— gravimetric procedures for chemical or electrochemical dissolution of the coating or the substrate to determine the coating surface density;

— gravimetric procedures for weighing the uncoated substrate and the coated (finished) specimen to determine the coating surface density;

— analytical procedures that utilize dissolution of the coating for determination of the coating surface density by instrumental chemical analysis methods.

With the exception of the gravimetric method described in ISO 3892 this document does not give the measurement uncertainties of the methods cited.
