ISO 1716 300ml Oxygen Bomb Calorimeter Instrument For Building Material

ISO 1716 Gross Heat Of Combustion Testing Bomb Calorimeter


Product Introduce

The ISO 1716 oxygen bomb calorimeter is a professional device used to determine the gross calorific value of combustion of building materials and fuels, in accordance with the ISO 1716:2018 international standard. By burning the sample in a constant volume of oxygen atmosphere, the water temperature rise is accurately measured and the heat released by the material is calculated (MJ/kg). The test is widely used in fire classification of building products (such as A1/A2 grades), fuel calorific value assessment and CE mark certification, and is suitable for insulation materials, plastics, coal, etc., to ensure fire safety and energy quality, and help meet EU CPR regulations.





Standard

ISO 1716:2018 (latest version)

Release date: May 2018

Content:

Specifies the method for determining the gross calorific value of solid products in a bomb calorimeter, with the test being carried out under a constant volume and oxygen atmosphere.

Includes sample preparation, combustion process, heat calculation and calibration methods, based on the temperature rise of water caused by combustion, taking into account heat losses and the latent heat of vaporization of water.

Appendix A provides the calculation method for the net heat of combustion (QPCI) (if required).

Appendix B provides information on the precision of the test method.

Note: Liquid products can be tested with similar equipment and conditions in accordance with ASTM D240, IEC 61039 or ISO 1928.

Test product scope

Building materials:

Homogeneous materials: such as mineral wool insulation, fiber reinforced cement board, silicate board, etc.

Heterogeneous materials (multi-layer composite materials): such as insulation with facings, sealing compounds, etc., each layer of material needs to be tested separately.

Fuel:

Solid fuel: such as coal, coke (refer to ASTM D5865).
Liquid fuel: such as gasoline, kerosene, fuel oil, diesel and gas turbine fuel (refer to ASTM D240).

Other combustible materials:

Plastics, rubber, wood, textiles, etc., used to evaluate their energy release potential.
Refuse derived fuel (RDF, refer to ASTM E711).

Typical application scenarios:

Building products must comply with the EU Construction Products Regulation (CPR), obtain the CE mark, and be classified into fire protection levels such as A1, A2, A1fl, A2fl, A1L, A2L.
