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 United Kingdom Testing and Certification can offer Reaction to Fire Testing Services through strategic partner laboratories that are UKAS accredited for this activity. 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.

UKTC's Impartiality Committee upholds unbiased business conduct. Ensuring critical impartiality in all testing and certification processes, we stand by our commitment to transparency and fairness in delivering our services. Impartiality Committee The UKTC Impartiality Committee ensures that we conduct our business in a critically impartial manner and in accordance with the latest standards and regulations. The Impartiality Committee Stephen Kerr Chairman of the Impartiality Committee Wylie Shanks Architects Senior Partner Having qualified in 1994, Stephen has since worked on an extensive range and value of projects, and although currently focused on healthcare he has also undertaken a considerable body of public authority, conservation, education, industrial and residential projects. His principal roles are to oversee the financial, marketing and administration aspects of his practice as well as being a key client contact and project leader. A key part of all construction projects is a requirement to understand and document the fire strategy required to successfully deliver a safe project. As a minimum, this strategy should meet the requirements of the Technical Standards, however, many clients often seek to better that baseline either through company policy, insurance stipulations or in the case of healthcare adherence to the NHS Estates publications (SHTM’s). Wylie Shanks Architects, led by Stephen, have significant experience in the development of designs and specifications to meet these varying and often changing demands. Working across both the private and public sector has also given him insight into their clients various demands for compliance, which typically requires backing up with reliable and evidence-based test documentation and certification. As a Chartered Architect, Stephen routinely acts as an impartial Contract Administrator on construction contracts as well as being professionally bound to act with integrity at all times by his professional Code of Conduct. Therefore, he is well positioned to perform the impartial duties expected from the Committee for which he represents.

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.
