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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 19993 was prepared by Technical Committee ISO/TC 165, Timber structures.

Introduction
This International Standard was developed by TC 165 as a factory quality-assurance test used for structural
glulam and applies to the face joints of each production batch. The frequency of testing and the pass/fail criteria
1)
are detailed in ISO 12578 . However, there is nothing in principle that prevents the test method from being
applied to non-structural glulam.
Dry specimens are tested under ambient conditions and wet specimens are tested under ambient conditions
after a vacuum-pressure soak.
