APPARATUS FOR SHEAR STABILITY OF LUBRICATING OILS CONTAINING POLYMERS AZA1329
The Apparatus for Shear Stability of Lubricating Oils Containing Polymers (Model: AZA1329) from AZA Lab is a high-precision KRL-type friction tester designed to determine the shear stability of lubricating oils and polymer-containing pressure fluids. It operates in accordance with DIN 51350-6 – Testing of Lubricants: Testing in the Shell Four-Ball Tester, Part 6, which defines the KRL method (Kugel Rollen Lager) for viscosity stability testing.
The instrument uses SKF 32008 tapered roller bearings as the friction pair to simulate the mechanical shear conditions experienced by lubricants in transmission and hydraulic systems. This test provides a reliable prediction of permanent viscosity loss, helping users evaluate the durability and performance stability of lubricants under stress.
Description
Working Principle
The AZA1329 KRL Tester applies controlled mechanical shear stress to the test lubricant inside a four-ball friction system equipped with a tapered roller bearing assembly.
Under specified conditions—speed of 1500 rpm, test force of 5000 N, temperature of 60°C, and test duration of approximately 20 hours—the lubricant experiences mechanical degradation similar to that occurring in real gear systems.
After the test, the viscosity is measured before and after shearing. The percentage decrease in viscosity represents the shear stability of the lubricant.
Construction and Design
The AZA1329 is built on a heavy-duty steel frame and includes a precision-controlled heating and cooling system. The testing chamber is embedded with the bearing and mandrel assembly, supported by advanced sensors and controllers to ensure consistent performance throughout the test duration.
The system consists of:
- Embedded test body and drive spindle
- SKF 32008 tapered roller friction pair
- Tapered roller bearing assembly
- Constant temperature control system
- Data acquisition and display interface

APPARATUS FOR HYDROGEN SULFIDE TESTER AZA1314
The Apparatus for Hydrogen Sulfide Tester AZA1314 from AZA Lab conforms to the ASTM D7621 Standard Test Method for the determination of hydrogen sulfide in fuel oils by rapid liquid phase extraction.
In this method, a weighed test sample is placed into a heated vessel containing a diluent base oil, where air is bubbled through to extract hydrogen sulfide gas. The extracted gas is then directed, via a vapor phase processor (Procedure A), to an H₂S-specific electrochemical detector, which measures its concentration in air and calculates the amount in the liquid phase in mg/kg. For Procedure B, the use of a filter cartridge is not required.
