| Use advice for data set | Scope: This ARGE EPD covers electromechanical hardware security devices used to control or enable door opening by means of electrical impulse. The reference product used to calculate the impact this group of products has on the environment is an item of electromechanical hardware such as a lock, handle or push button device. It is composed of steel, stainless steel and electric/electronic components. The product assessed for this EPD has 2 different configurations (grid-connected and battery-powered) and serves as a reference to cover all products within this family. The product has been confirmed in accordance with ARGE and the market share as the most representative product of the family. System boundary: This type of EPD covers “cradle to grave” requirements. The analysis of the product life cycle includes the production and transport of the raw materials, manufacture of the product and the packaging materials, which are declared in modules A1-A3. Losses during production are considered as waste and are sent for recycling. No recycling processes are taken into account except transport and an electricity consumption for grinding the metals. When recycled metals are used as raw material, only their transformation process is taken into account and not the extraction of the raw material. A4 module represents the transport of the finished product to the installation site. There is no waste associated with the installation of the product. The A5 module therefore represents only the disposal of the product packaging. B6 module represent the energy consumption of the product during use phase. For the RSL considered, results of B4 stage consider the use of batteries (battery-powered configuration). The End-of-Life (EoL) stages are also considered. The transportation to the EoL disposal site is taken into account in module C2. Module C4 covers the disposal of the device. Module C3 covers the recycling of the individual elements according to European averages, with the remaining waste divided between incineration and landfill. The same assumption as for waste to recycling in A3 is used here. For end of life modules (C1 to C4) the system boundaries from the XP P01-064/CN standard have been followed, for more information appendices H.2 and H.6 of this standard describe the rules that have been chosen. In practice, the end-of-life has been modelled as follows: - When material is sent for recycling, generic transport and electric consumption of a shredder is taken into account (corresponding to the process “Grinding, metals”). Only then is the material considered to have attained the “end-of-waste” state. - Each type of waste is modelled as transport to the treatment site over a distance of 30 km (source: /FD P01-015/). Parts sent for recycling include electricity consumption (grinding) and a flow (“Materials for recycling, unspecified”). Four scenarios for the end-of-life of the products have been declared for this EPD: 1. 100% of the product going to landfill 2.100% of the product going to incineration 3. 100% of the product going to recycling 4. mixed scenario consisting of the previous three scenarios, values depending on the amount of waste going for recycling. Module D has not been declared. |

| Technology description including background system | The production of an electromechanical hardware rnormally follows a 3 step procedure: 1. Prefabrication of the semi-finished products (usually by stamp punching or laser cutting) This step might include a surface treatment on factory site or by external manufacturers. 2. Preassembly of assembly modules (onsite factory) 3. Final assembly (onsite factory) Technical data: Ideally, products should comply with a suitable technical specification. /prEN 16867/ Mechatronic door furniture (still in draft form) is an example of such a specification and some products will comply with this. Declared unit: The declared unit for all products covered by ARGE EPD is 1 kg (of product). Since individual products will rarely weigh exactly 1 kg it is necessary to establish the exact weight of the product then use this as a correction factor to determine the true values for 1 kg of product in the tables (Section 5). |
