This Technical Report specifies the characteristics, test methods and checking. Calcium silicate slabs for thermal insulation will be covered by a future international standard. The requirements relate to general appearance and finish, geometrical characteristics (nominal length and width, thickness, tolerances on dimensions and shape), nominal density, bending strength, thermal conductivity, non-combustibility, fire protection, thermal shrinkage, moisture movement, sag under humidity, and srew retention.
