SimAir™ Test Cells for ASTM D2983
Specifications subject to change without notice. The use of programmable liquid baths for ASTM D has been allowed since the first development of the test if the cooling profile meets the specifications of Annex A2 of e2983 method.
The bath is supplied with an integral leveling viscometer support rod. Recommended accessories for BV Windows based PC proprietary software is capable of controlling two baths simultaneously. 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 sstm chambers allow simultaneous conditioning of samples at the same or different temperatures for quicker data collection then with aastm one apparatus.
Kits do not include the Brookfield Viscometer, which can be purchased separately. A digital, indicating controller with resolution of 0.
The twin air chambers are independently temperature controlled. Procedure B is used when a mechanically refrigerated programmable liquid bath is used to cool samples in preparation for viscosity measurement.
Home Products Contacts Search. A digital, dd2983 controller with resolution of 0.
The turntable holds 10 test samples. Referenced Documents purchase separately The documents listed below are d29983 within the subject standard but are not provided as part of the standard.
The illuminated jar allows full visibility of the test samples to facilitate the proper position of the spindle bead d2893 level. Recommended are at least 2 reference fluids for each desired test temp. No viewing window, but with digital sample temperature display. Measurement of the viscometric properties of these oils and fluids at low temperatures is often used to specify their acceptance for service.

Far superior viscosity data repeatability is obtained using this procedure as opposed to the air chamber procedure. D29883 Version s – view previous versions of standard. Model BV has an 28 cm 11 inch square, multipane, insulated window with fluorescent light for observation of the interior, with 28 sample capacity. No other units of measurement are included in this standard.

This allows operating baths at two independent temperatures with independent start, stop, and duration times. At least two reference fluids are recommended for d29833 desired test temperature per viscosity. A Windows based PC is required not supplied.
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. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: It is designed for those laboratories with a very light sample load and limited space and budget.
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.
Brookfield digital viscometer and DV Loader configuration software. Model BV is a smaller, floor space saving, compact unit, with 12 sample capacity.
Sample temperature digital display for D2893 BV70 only; included with others. This test method is used in a number of specifications. After the 16 hours conditioning time, the turntable is manually rotated until the proper test cell is under the viscometer.
