Restamping certificate for Waz. 3.1 and 2.2 .The basic rule is: an acceptance test certificate DIN EN 10204-3.1, known as WAZ 3.1, always covers a works certificate DIN EN 10204-2.2. It is important and mandatory that the declaration of conformity or the certificate of conformity is mentioned in the document! Only if an EN10204-3.1 acceptance test certificate is available for the corresponding profiles can we carry out a proper restamping. This restamping certificate is also expressly extended to our outside polished stainless steel profiles with marked laser protection film. This gives each marked stainless steel profile even greater product safety in terms of quality assurance. Marking is carried out directly on the material using an electrochemical process or by means of ink on the laser protection film.
