KN-1263 Leakage Tendencies of Automotive Wheel Bearing Greases

The test method provides a screening device that permits differentiation among products having distinctly different leakage characteristics. It is not the equivalent oflongtime service tests, nor is it intended to distinguish between wheel bearing greases showing similar or borderline leakageRead more >

KN-4290 Apparatus for Leakage Tendencies of Automotive Bearing Grease

This apparatus differentiates among wheel bearing greases having distinctly different high-temperature leakage characteristics. It is not the equivalent of longtime service testsRead more >

KN-1142 Dew Point for Gaseous Fuels

Generally, contracts governing the pipeline transmission of natural gas contain specifications limiting the maximum concentration of water vapor allowed. Excess water vapor can cause corrosive conditions,Read more >

KN-721 Petroleum Wax Oil Content Analyzer

The oil content of a wax may have significant effects on several of its properties, such as strength, hardness, flexibility, scuff resistance, coefficient of friction, coefficient of expansion, melting point, and oil straining. The importance of these effects may be dependent upon the ultimate use of the waxRead more >

KN-2872 Rolling Thin Film Oven

this oven indicates approximate change in properties of asphalt during conventional hot-mixing ar about 150℃ as indicated by viscosity and other rheological measurements.it yields a residue which approximates the asphalt condition as incorporated in the pavement.if the mixing temperature differs appreciably from the 150℃ level. more or less effect on properties will occur. this oven also can be used to determine mass change,which is a measure of asphalt volatilityRead more >

KN-1754 Thin Film Oven

this oven indicates approximate change in properties of asphalt during conventional hot-mixing at about 150℃ as indicated by viscosity,penetration,or ductility measurement,it yields a residue which approximates the asphalt condition as incorporated in the pavement. if the mixing temperature differs appreciably from the 150℃ level,more or less effect pm properties will occursRead more >

KN-88 Asphalt Saybolt Viscometer

KN-88 Asphalt Saybolt Viscometer is designed and made as ASTM D88 Standard Test Method for Saybolt Viscosity. It covers the empirical procedures for determining the Saybolt Universal or Saybolt Furol Viscosities of petroleum products at specified temperatures between 21 and 99℃ (70 and 210℉).Read more >

KN-4402 Rotational Viscometer for Asphalt Viscosity

KN-4402 Rotational Viscometer for Asphalt Viscosity conforms to ASTM D4402 Standard Test Method for Viscosity Determination of Asphalt at Elevated Temperatures Using a Rotational Viscometer. A rotational viscometer is used to measure the apparent viscosity of asphalt at elevated temperature. The torque on the apparatus-measuring geometry, rotating in a thermostatically controlled sample holder containing a sample of asphalt, is used to measure the relative resistance to rotation. The torque andRead more >

KN-36 Softening Point of Asphalt (Ring-and-Ball)

The softening point is useful in the classification of bitumens, as one element in establishing the uniformity of shipments or sources of supply, and is indicative of the tendency of the material to flow at elevated temperatures encountered in serviceRead more >
