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 1927-1 was prepared by Technical Committee ISO/TC 33, Refractories.

ISO 1927-1 cancels and replaces ISO 1927:1984, which has been technically revised.

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

Introduction

The general objective of this part of ISO 1927 is to define, with as much accuracy as possible, the control of monolithic (unshaped) refractory products with special reference to the following:

• a) quality control;
• b) checking the conformity of the delivery as compared with claimed properties;
• c) the control of batch homogeneity;
• d) the final control of linings.

Properties are unavoidably influenced by industrial placing as a result of the equipment, environmental conditions and often by specific site conditions (target date, location). Quality control and final control of lining should not be considered in the same documents, since the former requires accuracy and clean operative methods while the latter requires the control of the placing.

Monolithic (unshaped) refractory products used in industrial linings are generally not fired, so that the high temperatures which result from use create firing which results from use creates complicated conditions that make control difficult. The main points to be mentioned are:

• 1) the temperature gradient, the consequence of which is a property gradient;
• 2) the level of maximum temperature reached on the hot face directly depends on the working temperature of the equipment;
• 3) the life of the equipment may be numbered in hours or in years.

1 Scope

This part of ISO 1927 defines terms relating to monolithic (unshaped) refractory products and establishes a classification for the various types of product.

Raw materials and crushed or granulated refractory materials, which do not contain any binder, are excluded.
