Construction products – Giving shape to visions

IMA Dresden plays a leading role in the field of construction products. As an independent, renowned and accredited certification body, testing facility and inspection agency, it assists manufacturers, operators, suppliers and experts with all key issues relating to product compliance, life cycle, condition assessment, material characterisation and quality and safety standards.

You will receive good advice from us – against a backdrop of globalisation and regulation, we guide you through the requirements, testing processes and specifications of the applicable standards, policies and laws.

Together with the material testing of all metals, plastics, fibre composites and even textile-reinforced concrete, we offer a range of approval test, initial tests and technical tests for piping, pipeline parts and systems for water and gas supply, as well as wastewater disposal and components in general. We make statements about strength, durability, damage behaviour, ageing and functionality.

As an accredited Type A inspection body in accordance with DIN EN ISO/IEC 17020:2012, we offer you independent, neutral external production control of building products, also called external monitoring and inspections. As such, we provide you with support at your production and construction sites with incoming goods inspection, production documentation, plant production control, sampling and external product inspection.

The test mark of IMA Dresden gives you a recognised seal of quality for your products and manufacturing process, showing that your construction products match their type and are safe and reliable. In addition, we award the IMA certification mark based on technical specifications to assess product compliance. Independent inspections and monitoring by IMA prove the quality of your products. The IMA Dresden is accredited and recognised by numerous bodies, thus serving as a distinction for your product. You can use the IMA test mark for advertising and labelling purposes.
