DCLG publish results from the fifth large scale test
The latest wall cladding combination tested as part of the government’s series of large-scale fire safety tests has passed and meets current Building Regulations guidance. This fifth test was of a wall cladding system consisting of Aluminium Composite material (ACM) cladding with a limited combustibility filler (category 1 in screening tests) with PIR foam insulation. See full report at DCLG website

DCLG Press release

Expert panel recommends further tests on cladding and insulation

The independent expert panel on safety has advised further testing as the next step to be conducted in helping landlords to ensure the safety of their buildings.

These large scale tests will help establish how different types of Aluminium Composite Material (ACM) panels in combination with different types of insulation behave in a fire.

Government is acting to support owners and residents of high-rise buildings to ensure fire safety in the light of the Grenfell Tower tragedy. Landlords are engaging in a checking and testing process for Aluminium Composite Material (ACM) cladding.

The tests that are currently being conducted at BRE – on behalf of the Department for Communities and Local Government (DCLG) – are a screening test to identify which ACM panels are of concern. It tests the filler – the core of the panel – to check if it is of limited combustibility (category 1) or not (category 2 or 3). This is in line with the requirement of the Building Regulations guidance. The filler is one element of the overall cladding system. If the panel core achieves a category 2 or 3, landlords are expected to take the recommended interim fire safety measures issued by government on 22 June.
 
The equipment and procedures used in the screening tests are based on the BS EN ISO 1716:2010 test standard. As the purpose of this testing was to quickly and reliably screen the core material within the panel, the full procedures set out in that standard have not been followed as they are unnecessary to determine which type of panel has been submitted for the screening test. These screening tests should not be confused with a formal classification test against this standard.  
 
An independent expert panel has been set up to advise the government on other urgent steps that should be taken to improve fire safety. Our Chief Executive, Dr Peter Bonfield sits on that panel. They will issue advice imminently to clarify further steps landlords could take to inform their decisions on the cladding systems they have in place, and on checking insulation and other components of typical wall construction.

You can read further information and detail on the testing process on the gov.uk website

In an oral statement to The House of Commons on 3 July, Communities Secretary Sajid Javid said that the tests have been independently verified by research insitutes in Sweden.
