CE-ma?rkning av produkter under byggproduktfo?rordningen


The purpose of this study is to achieve an understanding of how a CE- marking process is conducted and to identify the relevant factors that must be considered in such a process. We have conducted our study at Lo?vhults Svets & Smide AB (Lo?vhults) in Skruv, Sma?land Sweden, which are manufacturing brackets for small covering constructions.To understand how a CE-marking process is conducted several documents and provisions have been reviewed to achieve a basic understanding and insight of the subject. It thus led to that guideline ETAG 015 were studied and the factors to be considered in the CE-marking of brackets were identified. Together with Jan-A?ke Johansson at Lo?vhults we agreed on four different brackets to investigate for a potential CE-marking. When these brackets had been selected a thorough investigation of these products was conducted, which then were compared with the provisions contained within ETAG 015. It states factors regarding the mechanical resistance, fire safety, environment, health, safety and usefulness that are to be considered. These factors should be specified and given a value / explanation which can be determined by European standards, calculation, calculation and testing, or only through testing. These calculations and tests shall be performed by the company or by a notified body.For a CE-marking to be possible to conduct it is mandatory to examine the manufacturing process of the products. Lo?vhults products are made of steel (Ymagine D1), which is processed in a punching machine, a bending machine, and finally a welding machine. After this processing, the products are sent for galvanizing and after which they are delivered back to Lo?vhults for dispatch to the customer. A production control procedure must be established and documented to ensure the quality of the manufactured products. The production control that we propose is simple in nature and is based on visual inspection of incoming materials, visual inspection of the work performed at each processing station and finally a visual check of incoming galvanized products. The manufacturing control needs to be approved by a notified body before it can be considered valid.The result of this study is that several correcting actions must be performed and that contact must be taken with a notified body to ensure that Lo?vhults products meet all the requirements that are demanded and thereby enable the products to receive a CE-marking.We have a discussion at the end of the report, resulting in the final conclusions and recommendations on whether the CE marking of Lo?vhults products is something that is worth investing in or not.
