Products in fibre-reinforced cement — Non-combustible fibre-reinforced boards of calcium silicate or cement for insulation and fire protection

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.
