Chemical and physical properties, and tolerances on dimensions and defects, for refractories of not less than 93% silica.

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.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
