Explore the Single Flame Source Test (BS EN ISO 11925-2:2020) which assesses a product's ignitability by direct small-flame impingement. Dive into the test process and criteria here Single Flame Source Test BS EN ISO 11925-2:2020 Single Flame Source Test (BS EN ISO 11925-2:2020) This method specifies a test for determining the ignitability of products by direct small-flame impingement under zero impressed irradiance using vertically oriented test specimens. The test specimens are cut from a sample which is representative of the product to be tested (e.g. it shall be tested as an assembly of component and not individually). When a substrate is used a specimen must be tested with a substrate representative of the end-use application. Each specimen is 250 ±2mm long and 90 ±2mm vide and are conditioned in accordance with 2.3. The samples are tested with 2 exposure conditions to a 20mm flame: Surface exposure – 40mm above bottom edge Edge exposure – at the bottom of the specimen 6 samples must be tested in each exposure – a total of 12 samples. The flame is applied for 15 or 30s, depending on the classification sought. The pass/fail criteria for classification are spread of flame to 150mm for the application of the burner flame.

Discover the non-combustibility test (BS EN ISO 1182:2020) for construction products, ensuring they won't contribute to fire. Understand the testing process and outcomes here. Learn More. Non-Combustibility Testing Non-combustibility test (BS EN ISO 1182:2020) This test identifies products that will not, or not significantly, contribute to fire, regardless of their end use. The fire test has been developed to selected construction products which produce a very limited amount of heat and flame when exposed to temperatures of approximately 750 °C. The test specimen shall be taken from a sample which is sufficiently large to be representative of the product and shall be cylindrical with a volume of 76 ± 8cm³ and diameter of 45+0mm and a height of ± 3mm. For non-homogenous (e.g., layered, or composite products) – each component or layer shall be tested separately. A minimum of 5 samples shall be tested for classification. After conditioning the samples must be dried in an oven at 60±5°C for 20-24hr. Prior to testing each sample is weighed to an accuracy of 0.01g. The samples are then inserted into a furnace that has been stabilised at 750 ±5°C for a minimum period of 30 min. The following data is recorded: Temperature of the furnace Temperature of the specimen centre and surface Any sustained flaming (3s or longer) The sample is then removed, allowed to cool, and weighed again. The test report will show: Mass loss (%) of each sample. Temperature rise of each sample Any sustained flaming

Dive into the BS EN 13823:2020 test process, where we assess building products' reaction to thermal attack by a single burning item. Single Burning Item (SBI) Test BS EN 13823:2020 Building products excluding floorings exposed to the thermal attack by a single burned item (BS EN 13823:2020) This procedure specifies a method of test for determining the rection to fire performance of construction products when exposed to thermal attack by a single burning item (SBI). The test specimen consists of 2 vertical wings forming a right-angled corner. The dimensions of the wings are: The long wing: 1500mm high x 1000mm long. The short wing 1500mm high x 500 + (thickness of long wing) mm long The maximum thickness shall be no more than 200mm. If the product is thicker than 200mm, then thickness shall be reduced on the unexposed side. The samples must be conditioned, a minimum of 3 samples must be tested. The extraction is set to a volume flow of 0.6=-0.05m³/s. Each test specimen is then fixed in the trolley and is exposed to a flame from a burner placed at the bottom of the corner. The flame is obtained by combustion of propane gas and gives heat output of 30.7±2kW. The flame is applied for 20 mins. The test apparatus measures the following: Temperatures of exhaust gases Volume flow in the exhaust Light attenuation (for measurement of smoke density) O2 and CO2 mole fraction of the exhaust gases. These quantities are recorded automatically and are used to calculate the Heat Release Rate (HRR) and Smoke Production Rate (SPR). A visual observation is also measured for flaming droplets an horizontal spread of flame. HRR is used to calculate FIGRA (fire growth rate) at 0.2 and 0.4MJ, and SPR is used to calculate SMOGRA (smoke growth rate). The test report is then written by the highly experienced UKTC team.

We test combustibility and contribution to fire development, ensuring compliance with BS EN 13501-1 standards. Partner with us for safety and assurance. Reaction to Fire Asses a construction material's contribution to the development and spread of a fire with a reaction to fire test. Have a Question, or want to make an enquiry? Fill out a quick form for a quote. Speak to Us Reaction to Fire testing examines the characteristics, such as combustibility, of building materials to determine their contribution to fire development and spread. Such materials can be classified into one of seven classes under BS EN 13501-1 according to their reaction to fire: A1 – Non-combustible materials, do not contribute to the development of a fire A2 – Materials with limited combustibility, do not contribute to the development of a fire B – Combustible, limited contribution to fire C – Combustible, minor contribution to fire D – Combustible, contributes to fire E – Combustible, will only resist a small flame for a few seconds F – Materials that have not been classified or have not met minimum requirements of class E. To obtain a classification, products are tested according to the following test methods: BS EN 13823:2020 + A1 2022 Single Burning Item (SBI) This procedure, likely the most recognisable of the tests, specifies a method of test for determining the reaction to fire of construction products when exposed to thermal attack by a single burning item.

BS 476 Part 22 is a key standard within the UK's building safety regulations that specifies methods for testing the fire resistance of non-loadbearing elements of construction, such as doors, shutters, and various types of ducts and dampers. This standard is instrumental in determining how these elements will perform in the event of a fire, ensuring they meet the necessary safety requirements to protect building occupants and property. What is BS EN 1634-1? BS EN 1634-1:2014 + A1:2018 is a European standard that specifies the test methods for assessing the fire resistance of door and shutter assemblies, including openable windows and elements of building hardware. This standard is crucial for evaluating how well these components can withstand fire, aiming to restrict fire development, limit its spread, and protect escape routes. How long does it take to get results? On completion of the test, the responsible officer will confirm the results within 24 hrs. This will be followed by a comprehensive draft report within 14 days. Can my product be changed from what was tested? Unlike fire resistance tests under British Standards, European standards provide a Direct Field of Application (DIAP) which detail the permissible changes from what was tested. An Extended Field of Application (EXAP) can also be undertaken which offers a great scope of variations than a DIAP. What is third-party certification? Third-party certification is independent verification that a product or service fulfils certain criteria. With passive fire protection products, this normally involves a certification body assessing test results, carrying out a factory production control audit and undertaking periodic inspections to ensure constancy of performance. UKTC work with many approved certification providers, including Bluesky Certification , IFC Certification and UL Solutions . What is UKCA Marking? UK Conformity Assessed (UKCA) marking is the new product marking which will be required for certain products placed on the market in Great Britain (England, Wales and Scotland). Does my product require UKCA Marking? The Construction Products Regulation in Great Britain states that any Construction Product covered by a UK Designated Standard must be UKCA marked. What is BS EN 13501-1? BS EN 13501-1 is a European standard that classifies the fire performance of a constriction product. The standard provides a framework, and series of tests used to determine how materials react to fire including its smoke production and flaming droplets. It assigns Euroclass ratings (A1, A2, B, C, D, E, F) to products based on their performance. What is an Extended Field of Application Report (EXAP)? Extended Field of Application (EXAP) reports present a prediction of performance based on one or more test results, thereby enabling a broader field of application while maintaining or enhancing performance to product in question.

Learn about the determination of gross heat of combustion test (BS EN ISO 1716:2018), a critical method for assessing a product's potential maximum total heat release. Gross Heat of Combustion BS EN ISO 1716:2018 Gross Heat of Combustion Test (BS EN ISO1716:2018) This test determines the potential maximum total heat release of a product when completely burned, regardless of its end use. This method determines the absolute value of the heat of combustion for a product without accounting for inherent product variability. The mass per unit area of each non-substantial component must be provided by the client or calculated in the laboratory. A minimum of 50g from a homogenous product or substantial component and 10g from any non-substantial component is to be sampled, ground into a fine powder and conditioned. After conditioning a 0.5g sample is selected and placed in a crucible inside the pressurised vessel (bomb), together with combustion aids if necessary (benzoic acid or paraffin oil). The bomb is then filled with 99.5% pure oxygen to a pressure of 30MPa. The bomb is then inserted into the testing apparatus which fills with water and the sample is ignited. The test apparatus measures the rise in temperature of the water and calculates the calorific value of the sample, considering any combustion aids. A total of 5 sample of each component are tested. The report will show the calorific value of each project in MJ/kg, Mj/m2 for each non-substantial component, and the total calorific value of the entire product.
