What do you mean by "test package"?
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

If the pipeline is a "DOT regulated line", most operating companies will have a formal Hydrotest Procedure to make sure the tested pipe and components meet the requirements of DOT “Transportation of Hazardous Liquids by Pipeline”, 49CFR.195, Subpart E and/or “Transportation of Natural or Other Gas by Pipeline” 49CFR Part 192 Subpart J.
Off the top of my head a few of the more important factors are pipe size/grade, desired operating pressure, elevation data along the pipeline route, test water source and water properties, post test treatment(biocides), test equipment specifications, test duration, documentation and reports etc. etc. The list is actually quite long of all the pertinent data and steps.
Long pipelines , say 150 to 200 miles can have several test segments depending on many of the factors mentioned.
LI,
Test Package is terminology generally used in the Southern Hemisphere.
All data relevant to the test (eg. Marked up P&ID's, marked up ISO's, NDT reports, PWHT reports if required, weld summary sheets, weld maps etc, etc) is compiled into a "package" and submitted for review and approval prior to release for hydrostatic or pneumatic test.
Hope I have interpreted the OP's question correctly (I based my response on B31.3 refinery work,not B31.4 pipeline work which may have totally different requirements)

Shane
