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.
On this page you can find out more about our wide range of services for pipe systems and fittings, facade systems and sandwich panels, construction elements, construction products and components, not to mention our proven quality in these areas.
Mechanical, physical and acoustic testing: from the pipe to the moulding, fitting and the overall system, we examine every detail. In addition to numerous initial and audit tests, we are a recognised and accredited inspection body for the monitoring of plant production control.
Building and installation technology
Our laboratory offers a range of options for individual and system tests of building and installation technology. From drinking water, heating or air conditioning to gas, we apply ourselves with the utmost care to plastic pipe systems, metallic pipe systems, composite pipe systems, control and extraction valves and water treatment systems. Make the most of our synergies with global certifying bodies through our international contacts.
Supply and disposal
The testing spectrum for supply and disposal systems begins with the type approval, proceeds to condition assessment in use and ends with comprehensive examinations of clean-up products. From thermoplastic pipes (smooth-walled or profiled), glass fibre-reinforced thermosetting pipes (GRP) and pipe liners to single- and multi-layered pipes, our expertise in testing ranges from pressure pipes (gas, drinking water, wastewater) and pressure-free pipes (wastewater, cable protection) to industrial pipelines and geothermal energy to renovation products. It also includes:
- Glass fibre-reinforced plastic (GRP) containers and tanks
- Containers and collecting devices made of thermosets and thermoplastics
- Containers and collecting devices and drainage-free collecting pits made of thermosetting plastics; reaction resins; textile reinforcement materials
- Containers and collecting devices and drainage-free collecting pits made of thermoplastics
Our range of services includes testing sheathing, insulation material and the whole composite system up to a 1,400 mm diameter, regardless of whether it comprises pipe systems with steel process tubes or flexible process tubes, bonded pipe systems or bonded double pipe systems. Our range of services is rounded out by the testing of moulded parts and fittings.

For this purpose, the sound emitted by the fitting is transmitted onto a measuring wall in our special testing laboratory, which records the airborne sound.

Sandwich elements testing
As a recognised testing, inspection and certification centre, we support you with initial type tests, approval checks and quality control of construction products and production facilities within the context of mechanical materials and component testing. On the basis of our accreditations and approvals, we are entitled to issue certificates of compliance (LBO, EBA) and certificates of constancy of performance and product conformity (EU Construction Products Regulation).
In accordance with the EN 14509 standards and guideliness, the DIBt sandwich guideline and the PPA Europe testing rules for panels and profiles, we test sandwich panels and their individual components: covering layers, fastening systems or core materials such as foam (rigid polyurethane foam, extruded polystyrene foam, phenolic foam) and mineral wool.
As part of industrial projects, in addition to approval product tests (assistance in obtaining general building inspectorate approvals, approvals in individual cases, approvals/certificates from quality associations), we also offer external monitoring of products and production facilities. In addition, we support you by providing our expertise and technological know-how in handling matters of research and development.
