SBI Test Equipment – EN 13823
Most construction products sold in Europe will shortly need to be tested and classified using a new test method called the Single Burning Item (the SBI) EN 13823. The construction products directive of the European commission will require that all European Member states eventually use this, instead of the traditional regulatory methods used in each country, to classify most building products.
The Commission recently defined the criteria for assessing building products into classes A-F. These are given in the table below. Though other test methods are required the SBI is needed to classify all non flooring products into the classes A2, B, C and D which are the major classes inhabited by most products other than those that are principally inorganic classified as non-combustible.
About SBI TEST?
The Single Burning Item (SBI), is a method of test for determining the reaction to fire behaviour of building products (excluding floorings) when exposed to the thermal attack by a single burning item (a sand-box burner supplied with propane). The specimen is mounted on a trolley that is positioned in a frame beneath an exhaust system. The reaction of the specimen to the burner is monitored instrumentally and visually. Heat and smoke release rates are measured instrumentally and physical characteristics are assessed by observation.
