Remarks.

JIS G3454 STPG 370 PIPE, STPG 410 CARBON STEEL PIPE

1. When the tensile test is carried out for No. 12 or No.5 test piece for the pipe under 8mm in wall thickness, the minimum value of elongation shall be obtained by subtracting
1.5% from the values of elongation given in Table 3-1 for each 1 mm decrease in wall thickness, and rounding off to an integer in accordance with JIS Z 8401. Examples of calculation are given in Informative Reference Table1.
2. The values of elongation given in Table 3-1 shall not be applied to the pipe whose nominal diameter is 25A or smaller. However, the value of elongation shall be recorded.
3. In sampling the tensile test pieces from the electric resistance welded steel pipe, NO.12 or No.5 test piece shall be taken from the portion not involving welded seams.
Informative Reference Table 1.
