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 3.
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 part of ISO 9652 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 9652-5 was prepared by Technical Committee ISO/TC 179, Masonry, Subcommittee
SC 3, Test methods.
ISO 9652 consists of the following parts, under the general title Masonry:
— Part 1: Unreinforced masonry design by calculation
— Part 2: Unreinforced masonry design by simple rules
— Part 3: Reinforced masonry design by calculation
— Part 4: Test methods
— Part 5: Vocabulary

Masonry —
Part 5:
Vocabulary
1 Scope
This part of ISO 9652 defines terms used in the structural design of unreinforced masonry.
This part of ISO 9652 is applicable to masonry in general, except for the following aspects of masonry design:
a) seismic design;
b) resistance to fire (see ISO/IEC Guide 52);
c) thermal insulation (see ISO 7345);
d) sound insulation.
NOTE It is assumed that the design of masonry is entrusted to structural or civil engineers or other appropriately qualified
persons for whose guidance this International Standard was prepared.
2 Normative reference
The following normative document contains provisions which, through reference in this text, constitute provisions of
this part of ISO 9652. For a dated reference, subsequent amendments to, or revisions of, the publications do not
apply. However, parties to agreements based on this part of ISO 9652 are encouraged to investigate the possibility
of applying the most recent edition of the normative document indicated below. For an undated reference, the latest
edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid
International Standards.
