Navy Asbestos Identification Proficiency Testing Program - Final Report to Laboratories - Test Round 117
The 117th test round of the Navy Asbestos Identification Proficiency Testing
Program began with the distribution on 1 May 2012 of test samples to 44 laboratories enrolled for participation. Program enrollment has slowly decreased from a maximum of 103 laboratories in mid-1994, resulting principally from a series of base closures and the decommissioning of numerous ships. That trend continues, with enrollment currently at its lowest level since Test Round 17 in early 1987, when 52 laboratories were enrolled.
Each test set distributed consisted of four samples, three of which contained asbestos. The asbestos-containing lots were a spray-on insulation (Lot B), an RTIformulated floor leveling compound (Lot C), and a fire door insulation (Lot D). Lot A, a cementitious exterior siding, did not contain asbestos. Complete reference analyses for the four sample lots are provided in Section II of this report.
