(Full size sample plate whose chord length is equal to Di is used for measurement.)1.Measure four inside diameters which distribute in the same distance at straight edge. The difference between the measured maximum value and the measured minimum value is the roundness tolerance.2.The roundness tolerance is not larger than 0.5 % Di, and 25mm;3.While δ s/Di < 0.005 , and δ s < 12mm, the roundness tolerance is not larger than 0.8 % Di, and 25mm. The tolerance of slope and dimension and groove roughnessprogramToleranceGroove Angle ± 2.5°Obtuse Width± 1mmGroove Roughness No defects such as flow, layered, inclusion are allowed.External circumference tolerance and inside diameter toleranceNominal diameterSteel products thicknessinside diameter tolerance ID External circumference toleranceDN < 6002 ≤ δ s < 4± 1.5± 44 ≤ δ s < 6± 2± 6δ s ≥ 6± 3-3~ 9600 ≤ DN < 10002 ≤ δ s < 4± 2± 64 ≤ δ s < 6± 2± 6δ s ≥ 6± 3-3~ 9DN ≥ 1000all± 3-3~ 9Notes:While Di ≥ 1000 and δs < 10mm , take external circumference tolerance as criterion. The inside diameter tolerance or the external circumference tolerance can be decided through the discussion between the two parties.Notes:1 Standard length of external circumference = (inside diameter nominal thickness 2 ) π (3.1416). 2 Under the circumstance of inside diameter tolerance, measure four inside diameters which distrib
