The standards sizes of all hard ferrite shapes mean the sizes of finished products which undergo.Sintering and grinding processes. Owing to the factors such as sintering temperture,intrinsic materical,Features and process controlling,size tolerances between designed sizes and that of finished products ate allowed.The tolerances are listed in the following tables.
