Materials Testing Laboratory

The year 2007 saw the amalgamation of Grenada Bureau of Standards with the Materials Laboratory of the Ministry of Works. Since then the Bureau’s Materials Testing Laboratory has continued provide testing services in accordance to ASTM, British and AASHTO standards. The Laboratory also provides conformity assessment services for technical regulations for construction sector.
