| Use advice for data set | The scope of the study is cradle to gate with options, with life cycle modules of A1-A3, A4, C1-C4 and D. B1 - B7 are excluded. The study takes into consideration the life cycle stages from the extraction of raw materials, production, processing and disposal, including all associated transport stages. The flowchart further illustrates the different stages of the product's life cycle considered. Module D includes the loads of melting and casting used aluminium potential benefits for the use of secondary aluminium outside the system boundary for the next product life cycle. |
| Technical purpose of product or process | EL-tjeneste aluminium crossbars are strong and lightweight products designed for use in power transmission and distribution grids in harsh weather climates. The aluminium crossbars come as a part of a modular system with various types of attachments and can be mounted on all types of poles; wood, composite, aluminium and steel. The low weight compared to strength gives opportunities for the product to be mounted in ways that have a low impact on surrounding environments. The products have a high expected lifetime and are fully recyclable at the end of life. EL-tjeneste aluminium crossbars are extruded profiles in aluminium alloy 6000-series and comes in a variety of sizes and shapes depending on function and direction of load. Length of the crossbar and distance between pole and line attachment depends on the voltage level of the power grid. All crossbars made by EL-tjeneste are anodized with a dark brown color, this gives a higher corrosion resistance and make them less visible in surrounding environment. The color is UV resistant and reduces light reflection. The results in the current EPD are given for an average of the different aluminium profiles. In order to calculate the environmental footprint of a specific crossbar, the values in this EPD must be multiplied with the weight/length ratio and total length given in each product's datasheet. This EPD covers crossbars with a total length above 6600mm that are made from aluminium profile nr. 1, 2, 3, 4, 5, 6, 8 and 9. |

| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |
