This European Standard shall be given the status of a national standard, either by publication
17、of an identical text or by endorsement, at the latest by March 1999, and conflicting national standards shall be withdrawn at the latest by March 1999. It is closely based on the corresponding International Standard, IS0 5013, Shaped reflactory products -Determination of modulus of rupture at elevat
