How are certificate costs incurred ?

Certificate costs arise from a large number of work steps required to create a certificate acc. to EN 10204-3.1.

The process chain begins with the daily production (casting and machining) of test rods,
the determination of the mechanical properties through a tensile test, as well as the chemical properties through sparking and a final documentation with the creation of the certificate
