The Quality Control Laboratory (QCL) of ARL is the first laboratory in the oil-refining sector of the country to achieve the coveted ISO 9002 accreditation. This land mark achievement was accomplished in May 1999 through completely indigenous efforts of our highly professional
QCL team. However, ISO 9002 certification is but only a small step towards our commitment to provide analytical services of highest order
to our customers.

Quality Control Laboratory of ARL has been awarded ISO/IEC 17025:2005 Accreditation by the Pakistan National Accreditation Council (PNAC), Ministry of Science and Technology, Government of Pakistan on October 4, 2007, thereby becoming the first and the only laboratory in the oil & gas sector of Pakistan to achieve this distinction.

ISO/IEC 17025:2005 Laboratory Accreditation is the criteria for laboratories to demonstrate the technical competence to carry out specific test methods, generate valid internationally traceable calibration data, test results, and operate an effective quality system. This accreditation, thus, gives ARL’s Laboratory an international standing equivalent to any of the international laboratories of repute.
