Material Testing Laboratory is designed to perform vigorous testing and competent assessment of components and equipment to meet relevant safety requirements. MTL offers type-testing to any national or international standards as well as testing for certification for the purpose of approving products which are manufactured in accordance with established Tanzania standards.
The Material Testing Laboratory has three sections:
Building and Construction Section
a) Designed for the testing of building materials as well as building components for properties such as strength and deformation properties, tightness, composition and dimensional changes and
b) Performs field investigations for various load tests and drilling of concrete cores from completed constructions for testing of strength.
Mechanical Engineering Section
a) Equipped with facilities for testing metallic materials with a wide range of tests being carried out to determine different properties of metals and
b) Offers consultancy services such as suitability for use of products needing general mechanical tests using local, national and international standards.
Electrical Engineering Section
a) Designed for testing households and similar electrical appliances as well as electrical materials and accessories and
b) Equipped with a modern multiple Earth Loop impedance’s prospective short circuit currents and for earth leakage circuit currents and for earth leakage circuit breaker testing in buildings.
Textile, Leather and Condom Laboratory

b) Providing training to the industries and small and medium enterprises (SMEs) on matters concerning quality packaging designs;
c) Conducting research and consultancy work on issues pertaining to quality packaging;
d) Providing third party certification for packaging materials and packages produced according to acceptable standards;
e) Providing testing services for packages and packaging materials;
f) Developing national standards on packages and packaging materials;
g) Facilitations of import and export of the packaging materials against relevant standards;
h) Providing information on packaging standards, requirements and technology.
The Cotton Laboratory is the Regional Technical Centre (RTC) for East and Central Africa under the Commercial Standardization of Instrument Testing of Cotton Project, co-founded by the European Union and the Common Fund for Commodities (CFC). The overall objective of the project is to assist the cotton producing countries in East and Central Africa to meet emerging quality assessment demands of the global cotton market so as to strengthen or at least maintain their competitive position in the world market.
The main services offered by the centre are:
a) Conducting training for laboratories and stakeholders in the region;
b) Conducting regional round trials;
c) Conducting retests on regional laboratory samples;
d) Providing expertise for cotton testing laboratories;
e) Collection and dissemination of technical information;
f) Facilitating the cooperation between cotton testing laboratories.
The main parameters currently checked in testing cotton samples are:
c) Length (UHML)
d) Length Uniformity (UI)
e) Colour Grade (Rd)
f) Colour Grade (+b)
