Type Approvals

GS-Hydro acknowledges that its customers follow different certification body’s rules and therefore GS-Hydro has made sure to be approved by all major certification bodies. In addition to type approvals of our GS-Products, GS-Hydro ensures that we have necessary type approvals for components which are delivered to us by our suppliers.

In general terms, type approval is a procedure for approval of standard designs or manufactured identical components. The design approval is done once, and this approval is made valid for all subsequent components of identical design. The GS-Products that hold the type approvals are tested according to IACS requirements. Read more on the IACS combined vibration & pressure pulsation test or the fire endurance test.
