Hydrostatic Test
Each length of pipe shall be subjected to the hydrostatic test or nondestructive examination.
 
Mechanical Tests Required
Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test-For material heat treated in a batch-type furnace, tests shall be made on 5 % of the pipe from each treated lot.
For small lots, at least 1 pipe shall be tested. For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5 % of the lot, but in no case less than 2 pipe.
 
Marking
In addition to the marking prescribed in Specification A 999/A 999M, the marking shall include the length, the ANSI schedule number and the heat number or manufacturer's number by which the heat can be identified.
