AIHA Bulk Asbestos Proficiency Analytical Testing Program for Laboratories Analyzing Asbestos by Polarized Light Microscopy

Participant Login

It is the intent of the American Industrial Hygiene Association (AIHA) to provide a proficiency analytical testing program for laboratories using polarized light microscopy (PLM) to analyze for asbestos in bulk building materials. Research Triangle Institute (RTI) has been designated to provide, on a quarterly basis, four different samples of bulk building materials, for analysis by participating laboratories. Each laboratory will, at the conclusion of a test round, be provided with an evaluation of its analysis results, a report of reference analyses for each sample, and a statistical summary of results from all laboratories participating in the round.

You have accessed the web site for AIHA's Bulk Asbestos Proficiency Analytical Testing Program. If you are already a program participant, please log in. If you are interested in becoming a participant, AIHA and RTI contact information is provided below.

AIHA's proficiency testing program for PLM laboratories is coordinated by RTI International.

Questions concerning this web site, test sample receipt and analysis, electronic submittal of your analysis results, or any aspect of this round of proficiency analytical testing should be directed to RTI Project Leader Bruce W. Harvey. Inquiries of an administrative nature (e.g., enrolling and disenrolling, payment of fees, etc.) should be directed to Anthony Hodge, AIHA Proficiency Analytical Testing Specialist.
