The Grenfell Tower Inquiry heard on Wednesday that the results of a fire test on its Reynobond PE product in cassette form, which was used on the tower, had not been shared with the British Board of Agrément. Instead, the BBA issued a fire-safety certificate for the Reynobond based on a successful test of the product when it had been riveted to a wall. Arconic was legally obliged to disclose to the BBA any other test data, which would include the cassette data, but it did not. The company that made cladding for Grenfell Tower did not tell certifiers about a "disastrous" failed fire test of the product which happened 13 years before the disaster, despite a legal requirement to do so.
