FROM SPECIMEN TO RESULT
Test sequence
Sequence outlined in the brochure for EN ISO 1716:2018.
- Weigh & prepare
Record sample mass; prepare the crucible and ignition assembly.
- Charge & load
Fill the closed bomb with oxygen externally, then place it in the water bucket.
- Ignite & record
Ignite electrically and record the stirred bucket water temperature rise.
- Calculate PCS
Apply calibration and method corrections; verify complete combustion.
TECHNICAL SPECIFICATIONS
Technical data
| Model | PW-OBC-01 |
|---|---|
| Method reference | EN ISO 1716:2018 — gross heat of combustion |
| Measurement principle | Combustion in oxygen at constant volume |
| Thermal arrangement | Isoperibol: constant jacket temperature; bucket temperature rises |
| Reported quantity | Gross heat of combustion, PCS, in MJ/kg |
| Temperature measurement | Separate precision measurement of bucket and jacket temperatures |
| Combustion vessel | Sealed oxygen bomb with crucible and electrical ignition |
| Operator interface | 7-inch touchscreen PLC/HMI; PC-based result analysis |
| Specimen handling | Manual bomb loading; separate external oxygen filling station |
| Calibration basis | Certified benzoic acid; configuration-specific energy equivalent |
The bomb is immersed in the bucket during testing. Low-energy samples require method-specific preparation, combustion aids and corrections.
