Lab ID NKM/EQ-138 (and additional units)
NKMPV runs several Hot Air (Drying) Ovens that hold samples at a controlled temperature — typically 110 ± 5 °C — to drive off moisture for oven-dry mass and water-content determinations. Drying ovens underpin a wide range of tests: soil moisture content, aggregate water absorption, and bituminous mixture conditioning.
What this equipment tests
- Soil water (moisture) content — IS 2720 (Part 2)
- Oven-dry mass of aggregate and water absorption
- Drying / conditioning of bituminous samples
- Loss on drying determinations
Applicable Indian Standards
- IS 2720 (Part 2) — Determination of water content of soil
- IS 2386 (Part 3) — Specific gravity, density & water absorption of aggregate
