From a Single Test
to a Continuous Program.
As you move deeper into the facility, the data gets denser and the stakes get higher. Each tier is designed for a different relationship with fuel quality risk.
Spot Analysis
A single ASTM or ISO method run on one sample. Select any method from our catalogue — viscosity, sulfur, flash point, or 130+ others. Results delivered as a method-specific test report.
- Any single ASTM method
- Chain-of-custody documentation
- Method traceability on report
- Digital delivery via secure portal
Compliance Bundle
A pre-configured suite of methods mapped to a specific fuel grade and regulatory standard. One submission covers density, viscosity, sulfur, flash point, water content, and corrosion — returning a single compliance certificate.
- ASTM D445 Kinematic Viscosity
- ASTM D4294 Sulfur Content
- ASTM D93 Flash Point
- ASTM D1298 Density
- ASTM D6304 Water Content
- ASTM D130 Copper Corrosion
- Full compliance certificate issued
- 48h standard turnaround
Continuous Program
Ongoing third-party testing under a standing agreement. Monthly or per-batch sampling, dedicated account management, LIMS portal access, and quarterly trend reporting. Designed for facilities where fuel quality is a continuous operational variable.
- All Compliance Bundle methods
- Dedicated LIMS portal access
- Quarterly trend analysis reports
- Priority 24h turnaround SLA
- Standing chain-of-custody protocol
- Expert consultation on exceedances
- Annual method calibration review
- Custom method additions available
Not sure which tier fits your situation? The Testing Standards Guide maps every method to fuel type, applicable regulation, and recommended testing frequency — giving you a complete picture before committing to a program.
Every Method.
Every Fuel Type.
Every Spec.
The Assay Testing Standards Guide is a 48-page technical reference mapping 140+ ASTM and ISO methods to their fuel type, applicable regulation, required sample volume, and standard turnaround time.
