With the aim of confirming the precision of analysis used by the Sri Lankan laboratories on analysis of Metallic Contaminants in foods, the Industrial Technology Institution (ITI) is planning to conduct a proficiency testing programme on Metallic Contaminants ( As, Cd, Pb and Hg) in food under its PECMA (Performance Evaluation of Chemical and Microbiology Analysis) PT scheme. PECMA is a third party, professional scheme, engaged in providing independent evidence of the validity of your laboratory test results. We have successfully conducted several microbiological & chemical proficiency testing rounds during the recent past in collaboration with other institutes/associations. This programme will be conducted in accordance with the requirements of ISO 17043:2010 (General requirements for proficiency testing) and other applicable international guidelines by our competent staff.


A sample of food containing Metallic Contaminants As, Cd, Pb and Hg (natural amounts in the range of ppm levels) in a reference material (RM) bought from an internationally recognized National Metrology Institution in the region will be used as the proficiency testing sample in this programme. The certified value for heavy metals given in the reference material certificate will be used as the assigned value for this proficiency testing programme.
