The Rust Preventing Characteristics Oil Bath is a high-precision, six-place constant temperature system designed to evaluate the corrosion and rust-preventive properties of petroleum products in accordance with NACE TM-01-72, ASTM D665, and D3603.
Featuring microprocessor-based temperature control, high-speed stirring, and robust stainless steel construction, this bath ensures consistent, repeatable performance for the assessment of antirust characteristics in gasoline, distillate fuels, and lubricating oils.
The Rust Preventing Characteristics Oil Bath is used to determine the antirust effectiveness of petroleum products by immersing polished steel test specimens in a stirred mixture of the test sample and distilled water at a controlled constant temperature.
This method helps control and monitor pipeline corrosion caused by condensed moisture in fuels and ensures that fuel and lubricant formulations meet corrosion-resistance standards.
The six-place constant temperature bath accommodates six 400 mL beakers and maintains test temperature with ±0.5°C (±1°F) stability. Each sample-water mixture is stirred at 1000 rpm by stainless steel paddles driven by an explosion-proof ball-bearing motor and polyester drive belt for long-term reliability.
The microprocessor temperature controller offers digital setpoint and display (°C/°F switchable), and an over-temperature protection circuit automatically interrupts power if the bath exceeds a preset cut-off point.
A perforated beaker support shelf, stainless steel construction, and chemical-resistant polyurethane enamel finish ensure durability in demanding lab environments.
Ideal for use in petroleum QA, corrosion control, and R&D applications, this oil bath provides exceptional accuracy, rugged performance, and compliance with international standards.
