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 documents 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
patents 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.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 135, Non-destructive testing, Subcommittee
SC 5, Radiation methods.
This second edition cancels and replaces the first edition (ISO 14096-1:2005), which has been technically
revised.
The main changes are as follows:
— definitions of terms 3.2, 3.6, 3.7, 3.13, 3.16 and 3.17 updated;
— clause 4 symbols and abbreviations added;
— in clause 5.1.3, details added on digitisers capable to capture densities D>4,5;
— in clause 5.1.5 details on the calculation of the standard deviation σ of the calibrated density D(gl ) and
D
Note 2 added;
D
— determination of the basic spatial resolution of the digitiser (SR ) added in the new clause 5.2.5;
b
— new clause 6 "Presentation of results” with a new figure 2 added;
— new table 2 with quality numbers for representation of results in fig. 2 added;
D
— new figure 1 presents examples of line pair test pattern for direct evaluation of SR ;
b
— “MTF calculation” moved to Annex A and “standard reference film” description moved to Annex B;
— editorial updated.
