Wasn’t there a fire test in Germany that tested an unplastered bale? My memory is that they wanted to certify a bare bale wall, so that subsequently, any plaster could be approved for use. I’m thinking that Dirk mentioned this test recently, in discussing a subsequent fire test with lime plaster. My memory is that the unplastered bale failed the test/time rating that they were aiming for.

Ok, so not 'unplastered', but 'slightly plastered' (Sounds like me after a night at the pub!)
I'm aware about approx. 5 national fire tests, but due to the cost and the aim they are all done with between 3-5 cm earthen plaster.
The only firetest I'm aware off which actually confirms that a clayslip is sufficient is the one carried out at the final evening of the excellent ESBG07 in Germany. -I just noticed that my hopelessly amateurish filming of it has received 12.986 on youtube!
I don't know if links work in this forum, if not then search for 'Strawbale fire test'
...But I'm afraid it's not going to convince the authorities...
