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;

-   descriptions of the locations of the measurement process and the effectivity of the results.

-   descriptions of the approval that establishes the validity of the measurements and the use of the properties for product design, design validation and other product characteristics such as structural integrity.

NOTE 2 Data representations described by this part of ISO 10303 might need to be archived to meet legal and regulatory requirements and to meet quality objectives.

The following are outside the scope of this part of ISO 10303:
-   data describing rules, guidelines and expert knowledge in the testing of products;

-   names of properties and test methods;

-   data describing why a decision was made to use a particular process;

-   scheduling data for measurement processes;

-   algorithms used for data evaluation and data processing.

NOTE 3 The names and definitions of properties and test methods are assumed to be provided in computer processable dictionaries, conforming to ISO 13584 Parts Libraries, which classify measurement methods and their associated property types.

This part of ISO 230 defines four tests, which are:

- an environmental temperature variation error (ETVE) test;

- a test for thermal distortion caused by rotating spindles;

- a test for thermal distortion caused by moving linear axes;

- a test for thermal distortion caused by rotary motion of components.

The tests for thermal distortion caused by moving linear axes (see clause 7) are applicable to numerically controlled (NC) machines only and are designed to quantify the effects of thermal expansion and contraction as well as the rotational deformation of structure. For practical reasons, the test methods described in clause 7 apply to machines with linear axes up to 2 000 mm in length. If they are used for machines with axes longer than 2 000 mm, a representative length of 2 000 mm in the normal range of each axis should be chosen for the tests.

The tests correspond to “drift test procedure” as described in A.4.2 of ISO/TR 16015, applied for machine tools.

This document specifies, with reference to ISO 230‐1 and ISO 230‐7, the geometric tests for general‐purpose, numerically controlled (NC) turning machines and turning centres with vertical workholding spindles, as well as the corresponding applicable tolerances.

This document explains different concepts or configurations and common features of NC turning machines and turning centres with vertical workholding spindles. It also provides a terminology and designation of controlled axes (see Figures 1, 2, 3, and 4).

This document deals only with the verification of the accuracy of the machine. It does not apply to the operational testing of the machine (e.g. vibration, abnormal noise, stick slip motion of components) nor to machine characteristics (e.g. speeds, feeds). Tests not concerning the geometric accuracy of the machine are dealt with in other parts of ISO 13041.
