The sample is oxidized in a pressure vessel initially charged with oxygen at 110psi (758kPa) and maintained at elevated temperature for a specified aging period. The pressure drop inside the pressure vessel is measured by means of a gauge or transducer.
Oxidation Bath–Constant temperature oil bath holds pressure vessels at the proper depth for determining oxidation stability of lubricating greases. Microprocessor PID control provides quick temperature stabilization without overshoot and the unit is protected by an overtemperature control circuit that interrupts power should bath temperature exceed a programmed cut-off point. Dual LED displays provide actual and setpoint temperature values in °C/°F format. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Contact your Koehler representative for information. Heavily insulated welded stainless steel bath interior has a pressure vessel support rack and overflow standpipe/drain to maintain proper working depth. Steel exterior has a corrosion-resistant polyurethane enamel finish.
Oxidation pressure vessel–Stainless steel pressure vessel consists of body, lid with stem and needle valve, and dish holder per ASTM specifications. pressure vessel interior surfaces and inside of stem have a high polish to facilitate cleaning. Safely withstands a working pressure of 180psi (1241kPa) at 99°C (210°F). Includes PTFE gasket seals (3) and cap screws with wrench. PTFE-fluorocarbon seals are available (see Accessories).
Pressure Measurement and Recording Equipment–Select mechanical pressure gauges or, for greater convenience and accuracy in test reporting, the Oxidata® Pressure Management System designed expressly for ASTM oxidation tests. Pressure gauge measures pressure inside Oxidation pressure vessel with accuracy of better than 0.5psi (3.45kPa) in accordance with ASTM specifications. Range: 0-160psi (0-1100kPa), graduated in 1psi intervals. Cleaned for oxygen service.
Oxidata® Pressure Measurement System–A complete electronic measurement system based on powerful Oxidata® software for Windows® and Windows 95® environments. Electronically measures and reports pressure versus time and accuracy of better than 0.5psi (3.45kPa) in the range of 0-200psi (0-1378kPa) for four channels in graphical tabular format.
Included RTD attachment permits measurement and reporting of bath temperature. Includes transducers, data acquisition card, multiplexer, Oxidata® software, RTD probe assembly and connecting cables and hardware. Refer to page 115 for complete specifications on Oxidata® software.
