Sterling Analytical provides professional NFPA 110 generator testing services to support facilities that depend on Emergency Power Supply Systems (EPSS) for life safety and operational continuity. Hospitals, data centers, municipalities, utilities, commercial buildings, and industrial facilities rely on compliant standby power systems to perform during outages. Our laboratory supports these operations with comprehensive fuel quality analysis and documentation aligned with NFPA 110 maintenance requirements.
NFPA 110 generator testing focuses on ensuring that emergency power systems remain fully operational and capable of immediate startup. A critical component of compliance involves verifying stored diesel fuel condition within generator storage tanks. Through ASTM-certified laboratory methodologies and defensible reporting, our NFPA 110 generator testing services evaluate contamination, degradation, and fuel stability to reduce failure risk during emergencies.
Stored diesel fuel degrades over time due to oxidation, water intrusion, microbial growth, and b. Without structured NFPA 110 generator testing, fuel-related deficiencies may remain undetected until a generator is required during a power outage. Our laboratory-based testing programs provide early detection and compliance documentation to support inspection readiness and operational reliability.
Sterling Analytical offers both a Basic NFPA 110 Generator Testing Package and advanced analytical services to fully evaluate diesel fuel condition in emergency power systems.
The basic test package evaluates whether stored diesel fuel meets operational and compliance requirements for emergency generator systems.
Clear and Bright – ASTM D4176: Visual inspection determines whether fuel is free of haze, suspended water, or particulate contamination. Fuel clarity is a fundamental indicator of storage condition under NFPA 110 generator testing programs.
Water and Sediment – ASTM D2709: This centrifuge method quantifies free water and suspended solids. Elevated levels indicate storage tank condensation, leaks, or contamination that may cause corrosion and filter plugging.
Water by Karl Fischer – ASTM D6304: Karl Fischer titration precisely measures dissolved water content. Even small concentrations can promote microbial growth and corrosion within emergency generator systems.
Flash Point – ASTM D93: Flash point testing verifies that diesel fuel has not been contaminated with volatile hydrocarbons such as gasoline. A reduced flash point may indicate cross-contamination and safety concerns.
Microbial Growth – ASTM D6469: Microbial screening detects bacteria and fungi present in long-term diesel storage. Microbial contamination contributes to sludge formation, acidic byproducts, and fuel system corrosion.
Particulate Contamination – ASTM D2276: This test measures insoluble particulate matter that can clog filters and impair injector performance during generator startup.
When expanded analysis is required for compliance or troubleshooting, advanced laboratory testing evaluates performance and regulatory parameters.
Distillation – ASTM D86: Characterizes the hydrocarbon boiling range profile to identify contamination or chemical breakdown.
API Gravity – ASTM D1298: Determines density for volumetric accuracy and combustion evaluation.
Copper Strip Corrosion – ASTM D130: Evaluates corrosive tendencies toward copper-containing fuel system components.
Sulfur – ASTM D5453: Quantifies sulfur concentration for emissions compliance and regulatory documentation.
Cetane Number – ASTM D976: Estimates ignition quality and startup reliability.
Cetane Index – ASTM D4737: Provides calculated ignition performance based on fuel composition.
Ash Content – ASTM D482: Measures inorganic residue contributing to combustion deposits.
Viscosity – ASTM D445: Determines fuel flow properties critical for injector and pump performance.
Viscosity – ASTM D445: Evaluates deposit-forming tendencies under high-temperature operating conditions.
Together, these analyses support a comprehensive NFPA 110 generator testing program that identifies contamination, degradation, and specification deviations in stored diesel fuel.
