| Property Analyzed: | |||
| Your choices are... | |||
| Blend Composition | Testers determine the relative amounts of constituent materials on a percent mass or percent volume basis. Applications include liquid fuel testing. | ||
| Brittleness / Friability | Brittleness or friability is a measure of how easily a material can be fractured, crushed, or broken. Brittleness can be determined by impacting the material with a controlled load. A very friable plastic, mineral, or abrasive would be considered weak and easily crushed or broken. A low-friability abrasive or mineral would be considered tougher and more difficult to mill or crush. The brittle point or ductile-to-brittle transition temperature is determined by testing a material at a series of decreasing temperatures until brittle behavior is observed. | ||
| Cohesion / Internal Friction | Testers or test equipment determine the cohesion or internal friction of materials. These properties can be important in understanding the processing or end-use function of powders, soils, sands, rocks, and granular materials. In geophysical applications, bore hole or shear tests are used to determine cohesion and internal friction. | ||
| Compactability / Compressibility | Testers or test equipment determine the compactability or compressibility of materials. These properties can be important in understanding the processing or end-use function of powders, foams, filter media and other compressible or porous materials. | ||
| Consistency / % Solids | Consistency is the amount of dry solids (% solids) or fibers in pulp or paper stock. It determines how the pulp can be formed and processed into paper. If the consistency is too thin or too thick, a paper web will not form properly. The specific consistency required depends on the paper-forming equipment used and the product being formed. | ||
| Contamination / Impurities | Contamination analysis determines presence or levels of toxic metals, dirt, inclusion, slag, shives, swarf, grinding debris, bacterial, microbial or other undesirable foreign substances in a material. Impurities in coal, hydrogen, biofuels, gasoline and other fuels can degrade combustion efficiency, foul engines, and pollute the environment. The amount of shives, dirt and stickle in pulp or paper can influence processability. Contaminants in a coating, ink, or adhesive mixture can result in streaks or repeating defects in the finished product. Impurities in coal, hydrogen, biofuels, gasoline and other fuels can degrade combustion efficiency, foul engines, and pollute the environment. An evaluation of the cleanliness, hygiene, or level of sterilization is very important for food, beverages, cosmetics, drugs, medical, biotech and pharmaceutical products. Specialized instruments or test equipment may be used to evaluate the cleanliness, hygiene, or level of sterilization applied to a material. Testers often use the detection of bacteria or ATP to determine cleanliness or sanitary properties. UV light sources can also be useful. | ||
| Core Sampling / Analysis | Test equipment is designed for core sampling or analysis. Coring or core sampling is done on powder bodies, soils, and geological materials to capture a true picture of variation through the material. Testing a powder or granular material by "scooping" from the surface can be misleading due to settlement and segregation effects. | ||
| Density - Loose Packed / Aerated | Loose packed density (LPD) or aerated density is the density of the powder or particulate body without any settlement, mechanical agitation, vibration, or tapping. Usually, loose packed density measurements are made by determining the mass of powder in a sample container of known volume. | ||
| Density - Tap / Packed | Tap or packed density is the density of the powder or particulate body after settlement from tapping, mechanical agitation, vibration, or light packing (not compaction or consolidation). Often, both loose packed and tap density measurements are made to determine the Hausner ratio, which is calculated by dividing the loose-packed density by the tap density. Carr index is also related to loose packed and tap densities. The Carr index and Hausner ratio provide an indication of flowability. | ||
| Flowability / Workability | Flowability provides an indication of the flow characteristics of a powder, granular material, slurry, or liquid. Powder flowability is determine through Carr index, basic flow index (BFI), Hausner ratio, angle of repose, internal friction, degree of floodability and other specialized or proprietary flow tests. Floodability is the degree to which a powder self-aerates and flows like a liquid. Slump tests determine the flowability or workability of a concrete, mortar or cement based material. | ||
| Sulfur Content | Testers determine the amount of sulfur in materials like coal. | ||
| Toxic Metal / Mercury Content | Frequently tested materials that are known to be harmful to humans, animals and other life include mercury, cadmium, lead, arsenic, chromium, polonium, and other radioactive metals and metalloids. Mercury naturally occurs in coal deposits and is emitted during the coal combustion process. Consequently, mercury content in coal fuel is often tested by a coal fuel testing device prior to use in coal-fired power plants. | ||
