05 Test Pressings
Before the main pressing starts, a short run of test pressings (TPs) is done and sent to the person who ordered the records to check for sound quality.
"Test Presses are used to check that the mastering engineer has done his job properly and that everything sounds fine before the main run is pressed."

You can ask for more if you like.
Some people use TPs as promotional copies but it's not necessarily too wise.
If the TPs aren't playable, your promotional schedule goes out of the window.
On the other hand, if your TPs are no good, it can mean that you need to re-cut the lacquers so all your release plans are going to end up in tatters anyway.
