Materials Testing Laboratories

Materials Testing Laboratories Unit has the mission of guaranteeing the quality of materials before use as well as their safety as required by the National or International Standards. Our Materials Testing Laboratories test the quality of various imported goods and locally manufactured products against the standards requirements. As for other RSB Laboratories, Materials Testing Laboratories is a potential service provider to RSB - Quality Assurance Unit, RSB - National Certification Division as well as to external customers. Working in line with ISO/IEC 17025 principles, we continue to be proud of the contribution of Materials Testing Laboratories to ensure consumer’s protection and trade promotion.
Operational since 2011, RSB Materials Testing Laboratories have been progressively expanding their testing capability by choosing technological testing solutions that increase customer confidence to our tests results. That is the reason why most of our testing equipment are software controlled and designed following international standard test methods.
Even though construction materials samples are the most frequently brought to us by our customers, our testing capacity goes beyond to cover polymers testing, and has basics capacity in Leather and textile testing.
The Unit has in place Non-Destructive Testing (NDT) facilities based on X-rays fluorescence principle and on FTIR molecular spectroscopy, modern techniques whereby materials are tested without damage for quick identification of their type and can still be used if they meet standards requirements after test.
Materials Testing Unit strives to continually meet customer satisfaction; where possible, our customers can propose test methods and researchers are free to bring samples and suggest test methods on their own in order to validate their research works.
