Spesifikasi Koehler K25319 Copper Strip Corrosion - Pressure Vessel Bath

Test Method

The Copper Strip Tarnish Test assesses the relative degree of corrosivity of petroleum products, including aviation fuels, automotive gasoline, natural gasoline, solvents, kerosene, diesel fuel, distillate fuel oil, lubricating oil and other products. 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. For aviation fuels and natural gasoline the sample tube is placed inside a stainless steel pressure vessel during testing


Conforms to the specifications of: ASTM D130; IP 154 

FSPT DT-28-65; ISO 2160; DIN 51759; FTM 791-5325; NF M 07-015

Testing Capacity:

K25310/K25319: four (4) copper strip corrosion test pressure vessels

K25320/K25329: eight (8) copper strip corrosion test pressure vessels or sixteen (16) test tubes with optional test rack

Maximum Temperature: 221°F (105°C)

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

Heater Range: 0-750W

Bath Medium: 5 gal (18.9L) water

Temperature Control: Analog, Digital


Thermostatically controlled water bath immerses Copper Strip Corrosion Test pressure vessels at the required depth per ASTM specifications. Use for testing aviation gasoline, aviation turbine fuel and natural gasoline. Fully insulated, double-wall stainless steel construction. Soxhlet reflux condenser and constant water level device maintain proper working depth. Choice of four-pressure vessel and eight-pressure vessel models. Optional removable test tube rack converts four-pressure vessel model for testing of products not requiring corrosion pressure vessel. Copper Strip Corrosion Test Pressure Vessel For aviation fuels and natural gasoline Precision machined stainless steel pressure vessel inserts in copper corrosion bath for testing aviation fuels and natural gasoline. Withstands test pressure of 100psi (689kPa) per specifications. Threaded cap with O-ring gasket and knurled circumference tightens by hand to a positive seal. A 1⁄8" groove in the pressure vessel threads permits safe, gradual release of pressure when opening the pressure vessel.
