ISO/IEC 17025:2017·
Lab ID NKM/EQ-223
The Saybolt Furol Viscometer measures the viscosity of bitumen and cutback bitumen as the time in seconds for a fixed volume to flow through a standard Furol orifice at a controlled temperature. Viscosity governs how a binder mixes, sprays and compacts, per IS 1206.
What this equipment tests
- Saybolt Furol viscosity of cutback / medium-curing bitumen
- Viscosity at specified temperatures (e.g. 25 / 40 / 60 °C)
- Binder flow characteristics for spraying and mixing
Applicable Indian Standards
- IS 1206 — Determination of viscosity of bitumen
- IS 217 — Cutback bitumen — specification
