Sample temperature digital display for Model BV70 only; included with others. Historical Version s – view previous versions of standard. Specifications subject to change without notice. Measurement of the viscometric properties of these oils and fluids at low temperatures is often used to specify their acceptance for service. Mercury, or its vapor, may be hazardous to health and corrosive to materials.
No viewing window, but with digital sample v2983 display.
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. Ample storage is provided inside the cold chambers for pre- cooling the insulated cell carriers. Ample storage is provided inside the cold chambers for pre- cooling the insulated cell carriers. Model BV is a compact, bench top unit with 6 sample capacity with digital sample temperature display.
Each model is equipped with turntable rotating at 4 RPM. Recommended are at least 2 reference fluids for each desired test temp. Recommended accessories for BV40 or BV Kits do not include the Brookfield Viscometer, which can be purchased separately.
SimAir™ Test Cells for ASTM D
Model BV has an 28 cm 11 inch square, multipane, insulated window with fluorescent light for observation of the interior, with 28 sample capacity. Far superior viscosity data repeatability is obtained using this procedure as opposed to the air chamber procedure. This allows operating baths at two independent temperatures with independent start, stop, and duration times.
Model BV is a smaller, floor space saving, compact unit, with 12 sample capacity. Link to Active This link will always route to the current Active version of the standard. Low temperature viscosity values obtained by either interpolation v2983 extrapolation of oils may be subject to errors caused by gelation and other forms of non-Newtonian response to spindle speed and torque.
The bath is supplied with an integral leveling viscometer support rod. The Lawler liquid baths are programmed such that the sample cooling rate equals the cooling rate experienced by a sample when immersed in the constant low temperature air chamber. Work Item s – proposed revisions of this standard. This test method is used in a number of specifications. At least two reference fluids are recommended for each desired test temperature per viscosity.

No other units of measurement are included in this standard. A Windows based PC is required not supplied. The spindle is connected while the sample is still in the liquid bath. Procedure C is used when a mechanically refrigerated constant temperature liquid bath is used to cool samples by means of a simulated air cell SimAir 3 Cell in preparation for viscosity measurement.

The twin air chambers are independently temperature controlled. The turntable holds 10 test samples. Model BV has two air test chambers. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
SimAir™ Test Cells for ASTM D2983
Each model is equipped with turntable rotating at 4 RPM. A digital, indicating controller with resolution of 0.
The illuminated jar allows full visibility of the test samples to facilitate the proper position r2983 the spindle bead immersion level. The success of the ATF correlation and the development of this test method has over time been applied to other fluids and lubricants such as gear oils, hydraulic fluids, and so forth.
A video chart recorder option -V to track possible temperature upsets, and a digital sample temperature display option -D d29983 available for Model BV This allows the measurement of viscosity without removing the sample from the temperature controlled environment.
Procedure B is used when a mechanically refrigerated programmable liquid bath is used to cool samples in preparation for viscosity measurement.
Model BV is a compact, bench top unit with 6 sample d293 with digital sample temperature display. A digital, indicating controller with resolution of 0. Model BV is a smaller, floor space saving, compact unit, with 12 sample capacity. Block Bath for sample preconditioning, 20 test positions.
