For issue of a certificate of conformity and for external supervision including Institut fürproduct tests that have to be carried out in this regard, manufacturer of anchor channels Bautechnik and bolts has to call in a certification body recognised for this purpose and a supervisory authority recognised for this purpose, including product checking. The assertion, that a certificate of conformity has been issued, must be given by manufacturer by means of labeling construction products with label of conformity (Ü-label), indicating designated use. The certification body has to submit to Bautechnik a copy of certificate of conformity it has issued. 2.3.2 Factory-conducted production monitoring The manufacturer shall set up its own department for conducting production monitoring at each plant. Manufacturer s production monitoring is understood as continuous monitoring of production process by manufacturer, with purpose of ensuring that construction products manufactured by him satisfy requirements of this.
