Ash Content
An Ash test is used to determine if a material is filled. The test will identify the total filler content. It cannot identify individual percentages in multi-filled materials without additional test procedures being performed. An ash test cannot be used to determine the percent carbon fiber or percent carbon black since carbon burns off during the Ash test.
Test Method : ASTM D2584, D5630, ISO 3451

Bulk Density
Bulk density is the weight per unit volume of material. The bulk density (morphology) of the rubber contributes significantly to the binder’s performance and is used as a property in the specification of the rubber. This test method provides a measure of the crumb rubber’s bulk density.
Test Method : ASTM D1895B

Compression Set Under Constant Deflection
Compression set testing is used to determine the ability of elastomeric materials to maintain elastic properties after prolonged compressive stress. The test measures the somewhat permanent deformation of the specimen after it has been exposed to compressive stress for a set time period. This test is particularly useful for applications in which elastomers would be in a constant pressure/release state.
Test Method : ASTM D395 B

Compression Properties
This test helps in determining the behavior of a material when it is subjected to a compressive load. The compressive strength of a material is the force per unit area that it can withstand in compression. This test helps us to design the rubber compound based on its application and service conditions.
Test Method : ASTM D695, ISO 604

Charpy Impact
This test helps in determining the material resistance to impact from a swinging pendulum. This test provides comparative values for various plastics easily and quickly. In this test, as in a flexural test, a standard test bar, 80mm long and with a cross-section of 4mm × 10mm is placed on supports 62mm apart, resting on the narrower side.
Test Method : ISO 179

Ferrography

Techniques that separate and arranges according to size, ferrous wear particles from a lubricant for analysis with a microscope. The Ferro gram provides information for the identification of wear particle types and a description of the wear mode that generates the particles.
Test Method

Viscosity
Viscosity is one of the most important properties of a lubricant as it determines both the film thickness of the oil and how readily the lubricant will flow into the narrow area separating the moving metal parts. Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress.
Test Method

Flash Point
The flash point is an indication of how easy a chemical may burn. Materials with higher flash points are less flammable or hazardous than chemicals with lower flash points. The flash point of a volatile liquid is the lowest temperature at which it can vaporize to form an ignitable mixture in air. Measuring a liquid's flash point requires an ignition source. At the flash point, the vapor may cease to burn when the source of ignition is removed.
Test Method

Fire Point
The fire point, a higher temperature, is defined as the temperature at which the vapor continues to burn after being ignited. Neither the flash point nor the fire point is related to the temperature of the ignition source or of the burning liquid, which are much higher.
Test Method

Cloud Point
The cloud point defines the temperature at which wax crystals appear in the fuel upon cooling. The cloud point of a fuel and its impact on cold flow properties should be monitored to ensure trouble-free operation in cold climates.
Test Method

Density
Density is a fundamental physical property that can be used in conjunction with other properties to characterize both the light and heavy fractions of petroleum and petroleum products. Determination of the density or relative density of petroleum and its products is necessary for the conversion of measured volumes to volumes at the standard temperature of 15°C.
Test Method

Pour Point
The pour point is the lowest temperature at which a fuel can be handled without excessive amounts of wax crystals forming out of solution. If a fuel is below the pour point, wax will begin to separate out and this will block filters.
Test Method

Conardson Carbon Residue (CCR)
Conardson carbon residue is the amount of carbon residue left after evaporation of an oil and to indicate relative coke-forming propensities. This test method is generally applicable to relatively nonvolatile petroleum products which partially decompose on distillation at atmospheric pressure.
Test Method

Water & Sediments
Water & sediments test is the volumetric percent of water and sediment in middle distillate fuels. Water and sediment in a fuel oil can cause fouling of the fuel-handling facilities, obstruct fuel flow and cause internal corrosion.
Test Method

Acid number (TAN)
Acid number test measures the acidity of a lubricant. Acid number is expressed by potassium hydroxide in mg required to neutralize free fatty acid in 1g of oil.
Test Method

Base number (TBN)
Base number measures of the amount of basic substances in the oil always under the conditions of the test. It is sometimes used as a measure of lubricant degradation in service. However, any condemning limit shall be empirically established.
