	In February 2018, BRE issued a statement revealing that the original tests they had carried out on the cladding system in 2014 were carried out on a test system that was not constructed according to Celotex’s design specification. The statement said; "The cladding system in that test included Celotex RS5000 and fibre cement board rainscreen (declared reaction to fire classification A2) – this was not an Aluminium Composite Material (ACM), nor was it the cladding system on Grenfell Tower." BRE made clear that they did not design, select or install the test system, and were not involved in the sample selection process.
