Specification of Koehler K35000 Corrosiveness and Oxidation Stability Test Apparatus

Test Method

Evaluates the ability of a lubricant to resist oxidation and the formation of corrosive acid compounds by subjecting a sample to accelerated oxidation conditions in a catalytic environment. The sample is maintained at elevated temperature and subjected to a controlled air flow while in the presence of a series of test specimens made of metals commonly found in actual service conditions.

Specifications

Conforms to the specifications of: A

STM D4636, D5968, D6594; FTM 791-5307, 791-5308; IHC BT-10; DIN 51394

Capacity: 6 test cells

Temperature Range: 125 to 750°F (51.7 to 399°C)

Temperature Control Stability: ±1°F (±0.5°C)

Air Flow Rate:

ASTM D4636/FTM 791-5307: 10L/h
FTM 791-5308: 3L/h and 5L/h (dual range flowmeters)
IHC BT-10: 3L/h (50mL/min.)

Features

Models for ASTM, Federal and IHC test methods
Six-sample testing capability
Solid aluminum block design
Microprocessor temperature control with digital display and overtemperature protection

Description

Constant temperature block baths for corrosivity and oxidation stability determinations on hydraulic oils, aircraft turbine lubricants, transmission fluids and other highly refined oils. Insulated aluminum block provides safe, efficient performance at operating temperatures of up to 750°F (399°C). Microprocessor temperature control has °C/°F switchable digital setpoint and display. Operator and equipment are protected by an overtemperature control circuit which automatically interrupts power to the unit should block temperature exceed a programmed cut-off point. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Contact your Koehler representative for information. Air flow is controlled at the specified rate by six individually adjustable flowmeters mounted on a common manifold. Includes inlet valve and outlet fitting for condenser water supply and support rack for glassware.
