The tensile test direction of No.11 and No.12 test piece is parallel to the pipe axis, while that of No.5 is perpendicular to the pipe axis. Note: The specification in this table shall not apply to the pipes whose nominal diameter is 32A (42.7mm) or under, but the elongation shall be still recorded. Elongation may be specified upon the agreement between the purchaser and the manufacturer. |
