| K25339 Copper Strip Tarnish Test Apparatus |
Test Method
The Copper Strip Tarnish Test assesses the relative degree of corrosivity of petroleum products, including lubricating oils. A polished copper strip is immersed in 30mL of sample at elevated temperature. After the test period, the strip is examined for evidence of corrosion and a classification number from 1-4 is assigned based on a comparison with the ASTM Copper Strip Corrosion Standards.Features and Benefits
• Conforms to ASTM D130, D6074, D6158 and related specifications
• Accommodates 16 test tubes
• Temperature range to 190°C (374°F)
• Microprocessor temperature control with digital display and overtemperature protection. |
K25339 Copper Strip Tarnish Test Apparatus
Constant temperature bath immerses 16 test tubes for copper strip tarnish tests of products not requiring a test bomb. 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 bath 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. Welded stainless steel double-wall construction with built-in support rack. Fully insulated.The complete apparatus for the Copper Strip Tarnish Test for lubricating oils consists of: Test Tube Bath Copper Strips Test Tubes ASTM Copper Strip Corrosion Test Standard Surface Preparation Accessories
