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 1927-7 was prepared by Technical Committee ISO/TC 33, Refractories.
ISO 1927 consists of the following parts, under the general title Monolithic (unshaped) refractory products:
— Part 1: Introduction and classification
— Part 2: Sampling for testing
— Part 3: Characterization as received
— Part 4: Determination of consistency of castables
— Part 5: Preparation and treatment of test pieces
— Part 6: Measurement of physical properties
— Part 7: Tests on pre-formed shapes
— Part 8: Determination of complementary properties
