AS 2341.19:1992 PDF Download

AS 2341.19:1992 is a standard that provides a defined methodology for determining the amount of insoluble matter in quinoline for tar. The purpose of this standard is to measure the percentage of refined tar that is unable to dissolve in quinoline, a specific solvent. This test is crucial for evaluating the quality and performance of tar used in roadmaking products.

The standard specifies the steps that need to be followed during the testing process. It outlines the necessary equipment, such as a filtration apparatus, as well as the required reagents and solvents, particularly quinoline. The procedure involves dissolving a weighed sample of tar in quinoline, followed by filtration and washing techniques to separate the insoluble matter from the solution. The remaining residue is then dried and reweighed to determine its mass, allowing for the calculation of the percentage of insoluble matter.

Complying with AS 2341.19:1992 is crucial in ensuring standardized and accurate testing for the insoluble matter content in tar.
