Quotations including guaranteed values subjectto tolerances should say so, and the tolerances should be in accordancewith the Attention is drawn to the different interpretation of the term some countries a distinction is made between guaranteed values andtypical or declared Where a tolerance is stated in only one direction, the value is not limitedin the other tolerancesAccording to IEC 72-1, the following tolerances on mechanical dimensions ofelectric motors are permitted:ParameterCodeTolerancesShaft lengthH- up to 250-0,5 mm- over 250-1 mm- from 11 to 28 mmj6 Diameter of shaft endD-DA- from 38 to 48 mmk6- from 55 to 100 mmm6 Hub key widthF-FAh9 Flange spigotN- up to 132j6- over size 132 h6 Note.
