Petroleum & Petroleum Products Laboratory

The physical and chemical characteristics of petroleum products can be analyzed in order to determine their quality, adequacy as well as compliance with specifications.

Test methods used are those stipulated by internationally known scientific bodies such as ASTM, ISO and IP.

Following is a list of some of the petroleum/and petroleum derivatives that can be analyzed and the analytical components or parameters that can be conducted:
