K35200 Humidity Cabinet for Testing Rust Protection


Test Method
Tests the ability of metal preservatives to prevent steel panels from rusting under conditions of high humidity. Polished steel panels are immersed in the sample oil and then suspended in the humidity cabinet for a specified test period.

Features and Benefits
• Conforms to ASTM D1748 and FTM 791-5310 specifications


K35200 Humidity Cabinet for Testing Rust Protection
Produces a moisture saturated atmosphere with continuous condensation at a constant 120F (48.9C) for 33 steel test specimens. Test panels are suspended on a 1/3rpm rotating stage. Air flow and water level control systems maintain required conditions inside the cabinet per Mil. Spec. and ASTM specifications. Air temperature is maintained at 120 2F (48.9 1.1C) by a digital LCD electronic controller. A continuous heater circuit assists the control heater in bringing the cabinet up to temperature prior to testing. Overtemperature protection is provided by an adjustable digital thermostat which cuts off power to the cabinet in case of overheating.

Cabinet interior is stainless steel lined and all interior components are of stainless steel or chrome plated steel construction. Hinged cover consists of two layers of desized cotton cloth mounted on a metal frame. Oil and condensate dripping from the specimens are collected in a drip pan and piped to an external drain.
