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.
Standard Compliance
ISO 1716:2018: Reaction to fire tests for products -- Determination
