Guidance for the application of ceramic fibrous materials which comprise the whole or a significant part of furnace insulating linings for temperatures of at least 800°C.

This code of practice recommends good working practice for the design and installation of insulating linings for furnaces where ceramic fibrous materials comprise the whole or a significant part of the lining. The code is concerned with furnaces generally operating at temperatures of 800 °C and over and mainly with clean conditions; abrasion and slagging, etc are excluded.

NOTE 1 This code is intended to be read in association with BS 7225-3.1.
