This Japanese Industrial Standard specifies the requirements for artificial abrasives made of alumina-base, alumina zirconia-base and silicon carbide-base materials (hereafter referred to as artificial abrasives) among artificial abrasives to be used for raw materials of abrasive products such as bonded abrasive products and coated abrasives and for other grinding or polishing processing. However, it does not apply to super-abrasives (diamond/CBN) or natural abrasives (e.g. garnet).
