not sure what value the the last 2 responses add to a learning discussion.
surely reporting a success of SPF on chipboard is of interest, even to those who only use expensive 2 part adhesive and plywood overlay......in all situations?
has no one else had success with SPF on chipboard?

For professional guys it can be very costly if the wrong stuff is used for a job. it is generally accepted that BAL SPF that you used is not suitable for tiling straight onto chipboard. Failures for a professional would not only cost money because of a call back under warranty, but more importantly, it can affect a hard earned reputation if word of failure gets around. We just can not take that chance. I have used a single part cementitous adhesive straight onto chipboard but not the BAL one. I used Ardexflex 7001 which is specially designed for the job, and was only a very small area (6m2).
Hopefully your floor will continue to be OK, but as was previously mentioned in the thread, it was a bit of a risk and you were prepared to take it.

I've just spent ages reading the posts on this thread and I've got to agree that there is no way BAL spf should be used in this circumstance.
I have recently been asked to repair a floor that another tiler had fixed; ceramic 300 x 300's directly on to green chipboard. The tiles have been down for approx 3 years and a lot of the grout lines are now cracked and approx 2m2 of tiles were cracked, too.
Surprise, surprise, the customer couldn't get hold of the original tiler. I refused the job unless the customer would let me rip the whole floor up and do it properly.
When you are expecting the tiles to stay down for a lifetime, you need to be prepared to fix them correctly first time!!

well in this particular circumstance the spf has been totally successful so far.
That's after 6 months of seasonal changes in temp and humidity, and heavy loading from few good parties and a good few cleans with mop and bucket.
I'll certainly let the Forum know if cracks do appear, but I can't see what mechanisms would cause this. Maybe failures that others have come across have been due more to poor workmanship, either in floor construction or tiling or both.
please don't bother to respond unless there's something useful to add. I fully acknowledge that I was in a position not to take the standard advice.....but then maybe there is something to be gained from my experience.

Graham, your feedback regarding this is very valuable, please keep it coming. The guys here on the forum can not see what the floor was like and we have had to go by your own assurances that it was solid. The adhesive that you used is an excellent adhesive, there is no question of that and if you floor proves to be as stable as it needs to be for this adhesive then that is good. However, if problems do arise within the original 10 year warranty period that BAL provided at the time, they will not entertain any claim you may try to make.
I, myself, tiled my own kitchen floor with Unibond floor adhesive before I took tiling up professionally. It was ok for the first few months, then the trouble started to show though - occasional crack in the grout here, then another one there and eventually, things started to "click" as you walked over the floor. It was only after I had undergone my training did I understand why. I still do occasionally tile straight to chipboard but only with what I consider appropriate adhesive. With a bit of luck, you will be fine, but please, if problems do arise, do let us know. We moderators will try very hard to control any "jibe" remarks that may come your way but you must fully expect the guys on here to say "told you so", in there own funny ways.

Update:
just to let you know the BAL spf onto floor grade chipboard has continued to perform.
my tiles are still firmly stuck down with no signs of cracking or any other form of distress.
that's another approx 4 months since my last report back in December, so 10 months in all since laying.
