≤15	＜0.02	＜0.15
15＜d≤25	＜0.03	＜0.20
25＜d≤32	＜0.04	＜0.25

In the case of the line between the decarburying depth SWCH30K and SWCH50K and the designation of the orderer, the test of 10.3.1 is performed, and the allowable limit of the average decarburying depth is in accordance with Table 4. However, for a line having a diameter of more than 32mm, it is according to the agreement between the receiving parties.

5. Allowance of wire diameter and differential deviation

Table 7 Allowance of Wire Diameter and Difference Difference

表7 线径公差和偏差

18<d≤30	0-0.070	0.013
30<d≤40	0-0.100	0.013
40<d≤50	0-0.150	0.013

Note (3) The deviation difference refers to the difference between the maximum value and the minimum value of the diameter in the same cross section of the line.
