ASTM D; IP Method A*. # to +30°C temperature range. # Accepts up to 12 SimAir® test cells. # Internal refrigeration unit. # Mounting for Brookfield. ASTM D Standard Test Method for Low-Temperature Viscosity of Automatic Transmission Fluids, Hydraulic Fluids, and Lubricants. ASTM D – Standard Test Method for Apparent Viscosity of Adhesives Having Shear-Rate-Dependent Flow Properties Using Rotational Viscometry. Scope.
This test method is used in a number of specifications. Model BV is a compact, bench top unit with 6 sample capacity with digital sample temperature display.
Recommended are at least 2 reference fluids for each desired test temp. Block Bath for sample preconditioning, 10 test positions. Windows based PC proprietary software is capable of controlling two baths simultaneously. A Windows based PC is required not supplied. Historical Version s – view previous versions of standard. Measurement of the viscometric properties of these oils and fluids at low temperatures is often used to specify their acceptance for service.
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 the method. Procedure A is used when only an air bath is used to cool samples in preparation for viscosity measurement.
Link to Active This link will always route to the current Active version of the standard. The illuminated jar allows full visibility of the test samples to facilitate the proper position of the spindle bead immersion level. The twin air chambers are independently temperature controlled.
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. 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.
Far superior viscosity data repeatability is obtained using this procedure as opposed to the air chamber procedure. The turntable holds 10 test samples. The spindle is connected while the sample is still awtm the liquid bath. Each model is equipped with turntable rotating at 4 RPM.

It is designed for those laboratories with a very light sample load and limited space and budget. Specifications subject to change without notice.
Asttm temperature digital display for Model BV70 only; included with others. Home Products Contacts Search. This allows the measurement of viscosity without removing the sample from the temperature controlled environment.
No viewing window, but with digital sample temperature display. Mercury, or its vapor, may be hazardous to health and corrosive to materials.
Ample storage is provided inside the cold chambers for pre- cooling the insulated cell carriers. No other units of measurement are included in this standard. Kits do not include the Brookfield Viscometer, which can be purchased separately. Recommended accessories for BV40 or BV This allows operating baths at two independent temperatures with independent start, stop, and duration times.
