Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 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, govern-
mental and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 501 9-4 was prepared by Technical Committee ISO/TC 33,
Refractories.
This second edition cancels and replaces the first edition (IS0 501 9-4 : 1 9941 , of which
it constitutes a technical revision.
IS0 501 9 consists of the following parts, under the general title Refractory bricks -
Dimensions:
Part 7: Rectangular bricks
Part 2: Arch bricks
Part 3: Rectangular checker bricks for regenerative furnaces
Part 4: Dome bricks for electric arc furnace roofs
Part 5: Skewbacks
Part 6: Basic bricks for oxygen steel-making converters
