Model 321 series of
oxidation stability baths conform to the requirements of EN-14122 test
method, incorporated in ASTM D6751 specifications for B100 fatty acid
methyl esters (FAME) for biodiesel blending.
Models 321 series employ an aluminum block configured to fit the specified test tube holding 3.0 gm of FAME (fatty acid methyl esters). When the sample reaches test temperature of 110ºC filtered, dry air is sparged at 10 ± 1L/hr. to each test specimen.
The volatiles generated (organic acids) from this
oxidation process are collected in a receiver of distilled or deionized
water. The increase of acidity in the receiver is measured with time
with an integral conductivity measuring device. The oxidation induction
period is automatically calculated based on the break in the rate of
increase (second derivative) of conductivity in the receiver.
Each position’s receiver has cap with an integral conductivity probe reporting data to the PC.
