10. Supplementary Requirements

S1. Product Analysis

Product analysis shall be made on each length of pipe. Individual lengths failing to conform to the chemical composition requirements shall be rejected.

S2. Transverse Tension Tests

A transverse tesnion test shall be made on a specimen from one end or both ends of each pipe NPS 8 and over. If this supplementary requirement is specified, the number of tests per pipe shall also be specified. If a specimen from any length fails to meet the required tensile properties (tensile, yield, and elongation), that length shall be rejected subject to retreatment in accordance with Specification A999/A999M and satisfactory retest.

S3. Flattening Test

S4. Metal Structure and Etching Tests

S5. Photomicrographs

S6. Photomicrographs for Individual Pieces

S7. Alternative Heat Treatment -Grade P91

S8. Melting Practice - Grades P2 and P12

Specific limits, if any, on grain size or deoxidation practice shall be a matter of agreement between the manufacturer and purchaser.
