Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.

Introduction
Online data recording is becoming more and more important. A major advantage is the accurate and
reliable recording of data within a minimum of time. It creates the foundation for fast and concise
evaluations based on data collected online, and enables validated decision taking.
These possibilities help create more transparency and improve the analysis of internal and external
procedures and processes. Thus, online data transfer helps to improve process quality and efficiency as
well as to increase customer satisfaction. However, along with the growing possibilities, also the number
of possibilities and variations for a multitude of solutions and the degree of complexity increases.
For this reason, the measuring values generating device manufacturers have to invest plenty of time
and effort for customer specific adaptations, as well as during the specification and control phase
at the customers and with regard to investment cost for implementation. To minimize this effort, a
generally valid data format was developed for an exchange of quality data in industrial production that
is independent of manufacturer and user.
With the objective to find a satisfactory solution for all parties involved, a number of users of the
software function “Data Interface” from the automotive production and supplier industry joined forces
to create a standardized and coordinated specification. The objective was to include a group of users in
this work group as big as possible, in order to get a representative cross-section through the scope and
interpretation of the key fields and their application. The result is a standardized catalogue of the data
fields important to every user.

Part 5:
Quality data exchange format for SPC software
1 Scope
This document describes a data format for the exchange of quality information:
— the data format is distinguished by a transparent structure that is easy to edit;
— it is flexible, space saving and easily be copied and compacted;
All files are language independent because of the allocation of an explicit key to a language independent
field, the content of which can be translated into any language required.
2 Normative references

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

4 Data model
4.1 Basic data model structure
A basic data model has been defined, which distinguishes between three main groups of data. The
highest level contains parts data, the second level characteristics data and the third level are data
related to the measured values. The characteristics data contain a voluntarily subgroup for quality
control chart application. Furthermore, separately from the three groups there are some key fields for
structure information.
This basic data model structure is illustrated in Figure 1.
