Copper Strip Corrosion by Liquefied Petroleum (LP) Gases


Koehler Instrument Company

Summary of Test Method


Tests the corrosiveness of LPG to copper by immersion of a polished test
strip in the sample inside a test cylinder at elevated temperature. After one hour the test strip is removed and compared against the ASTM Copper Strip Corrosion Standards.



LPG Copper Strip Corrosion Test Apparatus
• Conforms to ASTM D1838 and related specifications
• Four-sample testing capability

LPG Corrosion Test Cylinders

Stainless steel cylinder with 1⁄4" needle valves
for purging and admitting LPG samples. Dip tube with hook suspends copper strip in sample. Knurled, threaded cap with O-ring gasket hand tightens to a positive seal. Withstands hydrostatic test pressure of 1000 psig (6895kPa).

LPG Corrosion Test Water Bath

Thermostatically controlled water bath
submerges four LPG Corrosion Test Cylinders in an upright position.
Controls temperature at 100 ±1°F (37.8 ±0.5°C) per ASTM specifications.
Soxhlet reflux condenser and constant water level device maintain
proper working depth. Polished stainless steel inner wall and powder
coated steel outer wall construction. Fully insulated.
