High Precision ISO 1716 Bomb Calorimeter for Building Materials Heat of Combustion Testing
Product Information
The ISO 1716 Bomb Calorimeter is a high-precision instrument designed for determining the gross heat of combustion (calorific value) of solid materials, such as building products, biofuels, and composites, in accordance with ISO 1716:2018 standards. Widely used in fire safety testing, it measures the total heat released during complete combustion in a constant-volume environment, ensuring accurate results for materials like wood, plastics, rock wool, and textiles. This advanced calorimeter is essential for laboratories assessing fire reaction properties, offering reliable data for compliance with international safety regulations. Its robust design and precise measurement capabilities make it a critical tool for industries focused on material safety and performance.
