BS EN ISO 11925-2:2020 is a testing protocol used to determine the ignitability of a product by directly exposing a vertically oriented sample to a small flame. This “single burn item” test is one of the tests used as part of the Euroclass building product classification system which was introduced to harmonise standards across the EU.
A Single Burning Item test (SBI) is a method of testing that is used to determine the reaction to fire behaviour when a building product it is subject to thermal attack by a single heat source. The product being tested is mounted on a trolley and positioned in a frame beneath an exhaust system. As the item is exposed to flame, the exhaust system collects combustion gases for analysis and the amount of smoke produced is measured. The flame propagation and occurrence of burning particles and droplets are also identified in the specimen’s burning behaviour.
Zenova commissioned Warrington Fire to test its Zenova FP fire protection paint to the BS EN ISO 11925-2:2020 test standard. This test forms part of the testing programme to achieve BS EN 13501-1: 2018 classification.
A 9mm thick sheet of standard, untreated, plywood was painted with a 0.75mm coat of Zenova FP fire protection paint. Positioned vertically it was subjected to the SBI test and the flame spread observed and measured. The rating achieved is dependent upon the amount of flame spread, which must not exceed 150mm.
A flame spread of 40mm was observed on each test, which concluded that Zenova FP fire protection paint significantly helps reduce flame spread. The success of this test means Zenova FP fire protection paint tested to the BS EN ISO 11925-2: 2020 standard, can be used in construction, on a variety of substrates, to improve fire safety.
Also known as thermofoaming paint or Intumescent Paint, ZENOVA FP Fire Protection Paint is a fire-resistant water-based paint that prevents the ignition and spread of fire.
As a result of being exposed to heat, the intumescent paint swells and creates a light char foam, increasing in volume and decreasing in density. The heat transfer from the flames to the substrate is thereby greatly diminished. Treated materials become isolated from elements that maintain fire combustion since the paint turns into an insulating protective membrane.

Two kitchens were set on fire. The walls and ceiling of one kitchen were painted with Zenova FP fire protection paint. The benefits are clear.
A like for like test with a large global brand of fire retardent paint clearly shows a significant differance in performance.
