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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
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 the following
URL: www .iso .org/ iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee 9,
Laser and electro-optical systems.
This third edition cancels and replaces the second edition ISO 11551:2003 which has been technically
revised.
The main changes compared to the previous edition are as follows:
a) Introduction: The assumptions were revised in the second paragraph. Minor wording and example
adjustment in third paragraph.
b) Clause 4: Table for symbols and units was corrected.
c) Clause 5: More detailed specification of environmental conditions for UV- and IR applications are
provided in the second paragraph. ISO 7 specification was deleted.
In the fourth paragraph, Annex A is explicitly mentioned for the dependence of absorption on other
test parameters.
In the fifth paragraph, Annex B is explicitly mentioned to account for the critical issue of finite heat
conductivity.
d) In 7.2.3: In the first paragraph, the calibration procedure is specified in more detail, including the
consideration of the heating scheme for thick samples.
