Includes textural, thermal and mechanical properties. Products covered include ceramic fibre blankets, paper and board and loose bulk fibre.

This Part of BS 1902 describes methods of test for ceramic fibre products which are used as heat insulating materials at temperatures in the range from 1 000 °C to 1 600 °C. Typical products covered by this standard are loose fibres, blankets, felts, papers and boards. The test methods and their applicability to each product type are shown in Table 1.

An example of how to calculate a cooling correction, necessary when calculating specific heat capacity, is given in Appendix A.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
