IKIGO CY'IGIHUGU GITSURA UBUZIRANENGE

Materials testing laboratories unit has a mission of guaranteeing that all used materials in engineering works, either imported or locally manufactured country wide meet safety standards. Being the younger unit of the National Quality Testing Laboratories Division (NQTL) under Rwanda Standards Body (RSB), the testing capability in place covers mechanical tests of construction materials in general with basic equipment for testing Polymers and leather materials.

The unit has in place Non-Destructive Testing facilities based on X-rays fluorescence principle, a modern technique whereby tested materials are not damaged and can still be used if they are found to meet standards requirements after test.

Materials testing unit as for all departments in Rwanda Standards Body in general, is flexible to customer-needs and in the journey of meeting customer-satisfaction; our customers can propose the test method if possible; researchers are free to select test methods on their own in order to validate research works.

Our testing capability is the most extensive and comprehensive of its kind of materials engineering - including but not limited to the following:
