This British Standard specifies classification, the chemical and physical requirements, and tolerances on dimensions and defects, for silica refractories that contain not less than 93 % silica and are for use in coke oven construction.
It specifies the methods of sampling, testing and analysis to be used for bricks and shapes of silica material.
