I do not have the knowledge to advise or instruct anyone on how to use these test tapes. You will need to search the web for such information. It exists and I have seen it, however I cannot post links to those pages or endorse them due to my lack of technical knowledge on the applications of these test tapes.
These were originally issued to authorized audio and electronics engineers around the same time as the famous Tandberg 3014A cassette decks were being sold. Unfortunately, I cannot make any claims are to their origin and veracity, other than they appear to be a totally legitimate Tandberg issued product (please see available pics). They are professionally sealed, not an easy feat for just anyone to re-produce out of their basement.
They are not for everyone and therefore they are 100% non-refundable. You must absolutely know why you want to have one of these test tapes. It is advisable you have sufficient knowledge on how to use them. Once opened, they cannot ever be re-sold to anyone else as new.
