For the LantzZeitfuchs viscometer, apply slight vacuum to tube M or pressure to tube N with tube K closed until the lower meniscus is opposite the lower timing mark E; allow the sample to flow by gravity. In all cases, however, follow the general procedure described in 8.
If the sample is poured at a temperature above test temperature, wait 15 min for the sample in the viscometer to attain bath temperature and add more sample to overflow slightly into dd2170 K. On the Identification of Technology Shocks: The TV has a cover with seven openings and lids. Additionally the Cannon Instrument Co.
If the test temperature differs from the fill temperature, the viscometer constant is calculated as follows: It is a measure of the resistance to flow of a liquid under gravity.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. The flash point is determined in accordance with Test Method D Introduce sufficient sample through tube N to completely fill bulb D, overflowing slightly into overflow bulb K. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Introduce sample through tube N taking care not to wet the sides of tube N, into the cross-arm D until the leading edge stands within 0.
If the sample may contain lint, solid particles, etc. The time is measured for a fixed volume of liquid to flow under gravity through the capillary of a calibrated viscometer under a reproducible driving head and at a c2170 controlled and known temperature inside a viscosity bath.
The kinematic viscosity determined value is the product of the measured flow time and the calibration constant of the viscometer.
Or visit our webshop to get price and technical information for a viscosity bath and accessories to determine the kinematic viscosity of asphalts bitumens conform to ASTM D and ISO D viscometer calibration factor. Two such determinations are needed from which to calculate a kinematic viscosity result that is the average of two acceptable determined values. Work Item s – proposed revisions of this standard.
See Annex A1 for d170 method of calculation. Reverse-flow viscometers are used for the measurement of kinematic viscosities of opaque and transparent liquids up to cSt.
ASTM D – ASTM equipment
Mercury, or its vapor, may be hazardous to health and corrosive to materials. Link to Active This link will always route to the current Active version of the standard. The suggestions in the following sections of this appendix are given specifically for the mercury-in-glass kinematic viscosity thermometers and may not apply to other f2170.
ASTM D Standard
astj Historical Version s – view previous versions of standard. When thermometers are completely submerged, corrections for each individual thermometer based on calibration under conditions of complete submergence must be determined and applied. Certified kinematic viscosity values established are supplied with each sample. A charge of the erythrocyte test by automated method.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. The efficiency of the stirring and the balance between heat losses and heat input must be such that the temperature of the bath medium does not vary by more than Calibrated viscometers are available from a number of commercial suppliers. Results showed that the inclusion of PMMA polymer in asphalt binder has significantly improved its properties.
ASTM D2170/D2170M – 10
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Combining values from the two systems may result in non-conformance with the standard. The kinematic viscosity range is based on a s astmm flow-time in this method; the same viscometers are also described in Specifications D with a different viscosity range based on a s minimum flow-time as prescribed in Test Method D The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
Why is the kinematic viscosity of asphalts bitumens important to know? Measurement of viscosity of fluids.
In the IP this test method is under the jurisdiction of the Standardization Committee. The morphological studies of polymer modified binder were discussed.
