Popis
BS 1902-5.8:1992
This standard BS 1902-5.8:1992 Methods of testing refractory materials. Refractory and thermal properties is classified in these ICS categories:
- 81.080 Refractories
This Section of BS 1902-5 describes the method for determining the thermal conductivity of shaped refractory products, having oxidizable constituents, by a split column method. The method may also be used for non-oxidizable products.
The method is principally intended for materials having a thermal conductivity in the range 3 W/(m K) to 80 W/(m K) and for mean temperatures (test piece) in the range 300 °C to 850 °C.
The method is not applicable to materials with constituents which are volatile at temperatures within the range of the test.
NOTE The best accuracy is attained when the thermal conductivity of the test piece is close to that of the alloy steel blocks (see 6.2).
