ASTM D1837 & D2158

The ASTM D1837 and ASTM D2158 test methods cover the volatility or residue of liquefied petroleum gases. The test method is a measure of the relative purity of the various types of liquefied petroleum gases and helps to ensure volatility performance. For this test method, the sample is cooled down in a cooling coil and allowed to weather in the weathering tube. The Tamson TCC-B D1837 apparatus is able to keep the cooling coil at the appropriate testing temperature.
