Standard Test Method for Elastomer Compatibility of Lubricating Greases and Fluids
Summary:
ASTM 4289 is a measurement of the physical changes (swelling and hardening) in standard rubber coupons after total immersion in the lubricant sample. Catalyst (Stand alone) performance under the ASTM 4289 in NBR-L, FKM, and silicone were tested at 100% concentration.

Hydraulic Oil-Standard Test method for Wear Preventive Characteristics of Lubricating Fluid (Four-Ball Method)
Summary:
This report is compiled with standalone measurements and as added to Hydraulic Fluid to allow comparison on results. Performance under the ASTM D4172 shows the calculated average of the wear scar diameter on the three stationary steel balls used in the four-ball wear test machine. The 0.55 mm measurement indicates a very-good to excellent anti-wear performance of the Catalyst as a standalone product.The 0..45mm measurement indicates a excellent anti-wear performance of the Catalyst when add to a petrobased hydraulic fluid at a 1:15 ratio. The hydraulic oil with out Duravi Catalyst created an average score of .52 mm. this indicates a 13% reduction in wear when Duravi was added to the hydraulic fluid at a 1:15 ratio. (*always a good idea to check my math)

Fuel HFRR-Standard Test Method for Evaluating Lubricity of Diesel Fuels by the High-Frequency Reciprocating Rig
Summary:
This report is compiled with a standalone lubricity measurement of a #2 ULSD Diesel and "as treated" with Duravi FE at a 1:15 ration and a 2:15 ration to allow for comparison. The result of the standalone diesel was measured at 501um. The result for diesel treated with duravi at the 1:15 ratio was measured at 459um. The resutl for the deisel treated with Duravi at the 2;15 ration was measured at 447 um. This indicates improved lubricity of diesel fuel when Duravi is added at these ratios.

Standard Specification for Diesel Fuel
Summary:
This report is compiled with standalone #2 ULSD Diesel results for comparison with "as treated" with Duravi FE at a 1:15 ratio and a 2:15 ratio. The ASTM D975 is the Standard Specification for diesel fuel, defining key physical and chemical properties. The results of multiple test determine a Pass/Fail Criteria under the standard. The report shows that all three fuel samples ( diesel stand alone, and 2 treat with Duravi FE) passed the specification for #2 ULSD diesel.

Standard Test Method for Elastomer Compatibility of Lubricating Greases and Fluids
Summary:
ASTM 4289 is a measurement of the physical changes (swelling and hardening) in standard rubber coupons after total immersion in the lubricant sample. Fuel Enhancer (Stand alone) performance under the ASTM 4289 in NBR-L, FKM, and silicone were tested at 100% concentration. It is important to note that this product is recommended for use at a 1:15 ratio or 2 oz per 30 gallons of fuel. NBR-L measurements are acceptable in terms of compatibility*, FKM measurements are excellent*, and silicone measurements show that extreme caution should be taken*.

Standard Test Method for Cetane Number of Diesel Fuel Oil
Summary:
ASTM D613 is a standard test to determine the cetane number (or ignition quality) of diesel fuel. This indicates how quickly/efficiently the fuel ignites under compression. Higher cetane numbers indicate faster combustion, improving engine startabiliy, and noise reduction. It does not necessarily equate to higher fuel economy or increases in power. The results of 50.1 for 1:15 ratio treated diesel, and 51.5 for 2:15 ratio treated diesel, indicate a 4%-7% increase over the result of 48.1 for the non-Duravi treated diesel fuel.
