1.1 This practice covers dimensions in millimetres for standard series refractory brick and shapes of all compositions.

1.2 A standard method for converting all other dimensions of shaped refractory articles from inch-pound to SI units is included.

1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


3.1 This practice is provided in the interest of facilitating the transition of dimensional practice for standard refractory brick and shapes from inch-pound units to metric (SI) units.

3.2 The standard dimensions are based on a 38-mm module (taken as the equivalent to 1.5 in.) and are developed with the aim of preserving a modular relationship between the dimensions of the principal rectangular refractory shapes.
