SprinkCalc supports three international standards: NFPA 13-2025 (American), FM Global DS 8-9 (Insurance-approved), and BS EN 12845 (European/Turkish). Each standard has its own independent hazard classification system.
For the same ceiling and storage height, multiple ESFR K-factor values may be valid. The app selects the most economical option (highest K-factor = lowest pressure) as primary, while showing other valid alternatives for comparison.
Yes. BS EN 12845 uses independent classification based on Turkish Fire Regulation Annex 1/A (Low Hazard), Annex 1/B (Ordinary Hazard OH1-OH4), and Annex 1/C (High Hazard Process HHP1-HHP4). The same building type may fall into different hazard classes across different standards.
PDF reports include NFPA 13-2025 calculation results, sprinkler selections, hydraulic data, pump selection, and when applicable, an ESFR alternative K-factor comparison table.
No internet connection is required for calculations and PDF generation. All calculation data is stored locally on the device.
