摘要

Comments on modification of International standard ISO 5019/1,5019/2,5019/3 relating to the dimensions of rectangular bricks,arch bricks and rectangular checker brick for regenerative funaces have been put forward.It is considered that the thickness dimensions of the bricks in these international standards should be revised because they are converted from inch and are not multiples of 5,which brings some problems for bricklaying.The disance be-tween the big end and small end of arch bricks should be paid more attention.
