Testing Institute 

We are a certification and inspection body accredited by the Deutsche Institut für Bautechnik (DIBt) for various building products. DAkkS (Germany's National Accreditation Body) accredited us as a Testing Laboratory in accordance with DIN EN ISO / IEC 17025: 2005 (registration number: D-PL-18750-01-00 certificate: de/en).
The DIBt appointed us to several boards of experts:
  • SVA "Anchor points and attachments" -A
  • SVA "Scaffold anchors" -B5
  • SVA "Scaffolding" -A
  • SVA "Scaffolding / Service and working scaffolds" -B1
  • SVA "Scaffolding / Scaffold components" -B2
as well as in the project group
  • Shelving systems
We are an accredited body for performing tests and elaborating expert opinions in the context of approval procedures for the products mentioned.

In addition, we use our test facilities and our expertise as a testing laboratory for:
  • Experimental verification of stability analyzes
  • Experimental structural analysis of structures
  • Experimental studies in order to optimize the structural behaviour of construction products
  • Basic research for structural analyzes of new construction products

With our mobile equipment, we also perform tests at our clients’ premises or on construction sites.

 

We investigate and test the function of construction products !
