Steam Generators. Steam generators shall be tested in accordance with ASME
19.1.2
Performance Test Code, PTC 4.1, Steam Generating Units, which is currently being
revised. The changes which have been incorporated into the latest draft code, such as
the use of continuous analyzers instead of Orsat analyzers, are recommended for use.
For additional testing requirements see MIL-HDBK-1003/6.
