High-Speed Diesel (HSD) Fuel Testing
Accredited quality control and performance testing for Diesel Fuel as per IS 1460, BS-VI, and international standards.
Protecting Engines and Environment
Quality Assurance for Fuel Performance
Diesel fuel quality is paramount for the efficient operation, longevity, and environmental compliance of modern high-performance diesel engines. Substandard fuel can lead to poor combustion, increased emissions, filter clogging, and severe damage to costly fuel injection systems.
Our **Diesel Testing Laboratory** specializes in comprehensive analysis of High-Speed Diesel (HSD) and Biodiesel blends. We verify compliance with key national standards like **IS 1460:2017 (BS-VI)**, focusing on parameters such as **Sulphur Content**, **Cetane Number**, **Flash Point**, and **Viscosity**. Our certified reports are essential for bulk fuel buyers, transport companies, and manufacturers needing reliable quality validation.
Critical Physical and Chemical Parameters
Testing is performed to confirm engine compatibility, safety, energy content, and regulatory compliance.
Density and Specific Gravity
Crucial for calculating the calorific value and ensuring the correct volume-to-mass ratio for billing and engine performance.
Test Method: IS 1448 (P-16)/ASTM D4052
Viscosity (Kinematic)
Affects the fuel's lubrication properties and atomization in the injection system. Must be within specified limits for engine health.
Test Method: IS 1448 (P-25)/ASTM D445
Cetane Number / Cetane Index
Measures the fuel's ignition quality. A higher number indicates better, smoother cold starting and combustion.
Test Method: IS 1448 (P-39)/ASTM D613
Flash Point
The lowest temperature at which the fuel vapors ignite in the presence of an open flame. Critical for safety and transportation classification.
Test Method: IS 1448 (P-69)/ASTM D93
Sulphur Content
Measurement of sulfur concentration, vital for environmental compliance (BS-VI/Euro-VI norms) and preventing engine wear and catalyst poisoning.
Test Method: IS 1448 (P-107)/ASTM D4294
Water and Sediment Content
Checks for contamination that can damage fuel pumps, injectors, and filters, and lead to microbial growth.
Test Method: IS 1448 (P-30)/ASTM D2709
Distillation Range
Determines the volatility and component makeup of the fuel, which directly impacts engine starting, warm-up, and power output.
Test Method: IS 1448 (P-15)/ASTM D86
Cold Flow Properties (Cloud & Pour Point)
Indicates the lowest temperatures at which the fuel remains fluid. Essential for reliable operation in cold climates.
Test Method: IS 1448 (P-10)/ASTM D2500
