Is this product suitable as a solvent cement for abs pipes?
According to the marking on the tube it's rated for both EN14680 (Adhesives for non-pressure thermoplastics piping systems) as well as EN14814 (Adhesives for thermoplastic piping systems for fluids under pressure).
The product datasheet I found says:


  Tangit PVC-U is suitable for producing tensile stress resistant
  connections between pipes (e.g. drinking water and gas pipes) and
  fittings made of PVC-U* in compliance with the recommendations of the
  German Plastic Pipe Association.
  *PVC-U = rigid PVC  


But - on page 2 it says:  


  The recommended product for pipes made of ABS is Tangit ABS  


My best guess is that it'll probably work sorta-kinda-ok-ish, but I wouldn't use your PVC-U on ABS pipes except as a last resort in a non-demanding application.
