<p>We are aware of one BS 8414 test carried out in the UK in 2014 on High Pressure
Laminate (HPL) panels in combination with a combustible insulation material. This
test was commissioned by a private company and the Department only became aware of
the test in November 2018. We understand that the arrangement tested failed to meet
the criteria for passing the test. The Department’s Advice Note 14, first issued in
December 2017 and reissued in December 2018, made clear that a wall system which did
not contain materials of limited combustibility would only meet the requirements of
Building Regulations’ guidance if it had passed a BS 8414 test. The Department has
commissioned its own BS 8414 test of an HPL panel with non-combustible insulation
as well as carrying out a programme to research the performance in a fire of non-aluminium
composite materials, including HPL.</p>
