2.6 Base materials / Ancillary materials The material TECU® copper consists of 100 % Cu-DHP according to DIN En 1172, i.e. oxygen-free phosphorus de-oxidised copper with limited residual phospho-rus. The degree of purity is at least 99.90 % copper. Only internal and external scrap is used in production. Primary copper cathode is not used. Additives: Rolling oil-emulsion: 0.544 g/kg Cu is a highly refined mineral oil containing organic esters, polyhydrocarbons, and antioxidants which is used for cooling and lubrication during the rolling process. The rolling oil emulsion is biodegradable. Benzotriazole:...

tion 2.6. The changes in colour of the surface are caused by: Further weathering causes the oxide layer to gradually grow; the thicker and denser it gets, the slower this growth becomes. Green Patina: the building geometry and the local climate can cause the formation of the green patina that is typical for copper. If TECU® products with a pre-oxidised or pre-patinated surface (TECU® Oxide, TECU® Patina) are subjected to weathering; copper compounds also form in the above-described manner. 2.12 Environment and health during use There will be no affects to health if the TECU® Eco products are...

3.3 Estimates and assumptions For transports, an average transport distance of 300 km was assumed. The wooden pallets are assumed to be circulation material that is to be reused. Therefore they are not considered within the declared modules. The catalyst used in Patina-coating is assumed to be copper-chloride 3.4 Cut-off criteria All material flows that enter the system and are over 1 % of their entire mass or contribute more than 1 % to the primary energy consumption, were taken into consideration on the input side. All material flows that exit the system and whose environmental impact makes...

The following tabels show the results oft the LCA Environmental Impact Assessment, the Ressource Use, the waste-flows and other output-flows of 1 kg copper sheet produced by the KME Germany GmbH & Co. KG. The result of the environmental impact assessment is only a relative statement. It gives noch Information about endpoints of the impact assessment, if threshold Values are exceeded, safety margins or risiks. * The indicators are not reported according to the temporary agreement of the advisory board meeting from 04.10.2012.

LCA: Interpretation The Ozon Depletion Potential (ODP) is mostly influenced by the generation of electricity and the provision of charcoal. In the production process, the main contributer to the Eutrophication Potential (EP), is the gernation of thermal and electrical energy. Acidifiation Potential (AP) and the Photochemical Ozone Creating Potential (POCP) are also mainly dominated by the generation of electricity. Transports for the TECU® Eco products, in the case of POCP, have a positive effect. The reason is, that the Nitrogenmonoxide-Emissions that occure during transportation, have a negative...

Requisite evidence 7.1 Withering Calculation model for copper elutiration: A formula was developped on the basis of publicly available and laboratory data, which calculates the elutiration in a grid of 50 m² in Europe. The key parameters in this formula are the SO2-Concentration, the pH-Value of rain, the precipitation and the roof pitch. Experimental setup: acccordint to ISO 17752, trial period 2007 – 2010, trial site Duisburg.http://www.corrosionsience.se/runoff/ KME Germany GmbH & Co. KG – TECU®-Eco copper sheets and strips
