REFERANCE FLUID ISO IRM-903, offers high stability and reliability in elastomer and rubber tests according to ASTM D471 standard and is a reference test oil.

REFERANCE FLUID ISO IRM-903 | Test Oil Reference Fluids

REFERANCE FLUID ISO IRM-903 is a high-quality test oil reference fluid formulated in accordance with the ASTM D471 standard. It plays a critical role in the comparative analysis of oils used in elastomer and rubber production and provides superior consistency in quality control processes.

Features and Advantages:

• High temperature stability makes it resistant to challenging working conditions.

• Excellent water resistance and mechanical stability with oxidation.

• Provides effective protection against corrosion.

• Its durable structure and high adhesion property provide long-lasting lubrication.

• Shows superior resistance to wear with a low evaporation rate.

Applications:

• Closed industrial bearings and systems

• Automatic and central lubrication applications

• Joints, connections, and slides

• Rolling element and sliding bearings

• Protective and rust-preventive film applications

Technical Specifications:

• Viscosity @40°C: 268.70 cSt (ASTM D445)

• Viscosity @100°C: 19.75 cSt (ASTM D445)

• Aniline Point: 93.30°C (ASTM D611)

• Paraffinic Carbon Content: <%50 (ASTM D2140)

• Flash Point: >240°C (ASTM D92)

Technical Data and Features

Restoreplus Referance Fluid ISO IRM-903 is prepared based on this reference and the common technical values possessed by its equivalents replacing products in this segment are as follows:

• High Aromatic Content: IRM-903 is the most aggressive test oil in the series. With its high aromatic structure, it creates the Maximum Swelling and softening effect on rubber and elastomer materials, testing the material's resistance to the harshest chemical conditions.

• ASTM D5964 and ISO 1817 Compliance: It is the only reference fluid with international validity in volume change, mass gain, and tensile strength tests conducted in a laboratory environment.

• Low Aniline Point: The ability of the oil to penetrate the molecular structure of the material is determined by the aniline point, which is fixed at 70°C in this product. This low value shows how much the oil is "solvent" and "swelling" for elastomers.

• Elastomer Approval Processes: It is mandatory in the quality control and OEM Approval (Mercedes, VW, Ford, etc.) tests, especially for engine gaskets, fuel hoses, and seals (e.g., NBR, CR, FKM).

• Precise Calibration: Each production batch is manufactured within very narrow physical and chemical tolerance ranges to provide repeatable results in tests worldwide.

• Thermal Stability: It exhibits high thermal stability to maintain its physical properties in high-temperature immersion tests (e.g., 168 hours) generally between 100°C and 150°C.

• Volume Change Measurement: By measuring the expansion amount of the material in this oil, it determines the sealing performance in real working conditions in advance.

Applications: This product is used in all R&D and Quality Control laboratories in the automotive industry, defense industry, aerospace, and rubber parts manufacturing sectors to classify the oil resistance of materials.
