适用范围：Foreword Because of the difficulties reported in obtaining sheet material to produce washers to the required imperial thicknesses, this 1979 edition has been prepared to specify the washer thicknesses in metric units. Reasonable thickness tolerances are specified to cover a broad band of the sheet tolerances available. Imperial thickness materials may still be used if the overall tolerances are maintained. Amendment No. 1 (AMD 1185) to the 1970 edition, which specified dimensions of oversizes, has been incorporated.
