| Use advice for data set | Scope: This ARGE EPD covers mechanically operated push button locks, used to secure openings by purely mechanical means (i.e.no electrics/electronics). The reference product selected to calculate the impact this group of products has on the environment is a push button lock composed primarily of brass and zinc-based alloy. This product is the only one assessed for this EPD and serves as a reference to cover all ARGE member products within this family. It has been determined in accordance with ARGE and the market share as the most representative product of the family. System boundary: The type of the 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 to recycling. No recycling processes are taken into account except transport and electricity consumption for grinding the metals. When recycled metals are used as raw material, only their transformation process is taken into account - not the extraction process. 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. For the RSL considered for this study, there are no inputs or outputs for the stages B1-B7. 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 locks. 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, see annex H.2 and H.6 of this document for figures and further details. In practice, the end-of-life has been modeled as follows: - When material is sent to recycling generic transport and electric consumption of a shredder is taken into account (corresponding to the process “Grinding, metals”). Only then is the material is considered to have attained the “end of waste” state. - Each type of waste is modelled as a transport to the treatment site over a distance of 30 km (source: FD P01-015). Parts sent to recycling include an 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 in landfill - 2. 100% of the product going in incineration - 3. 100% of the product going in recycling - 4. mixed scenario consisting of the previous three scenarios, values depending of the amount of waste going to recycling. Module D has not been declared. |
| Technical purpose of product or process | These products are designed to be integrated into door assemblies of varying materials and applications. They can be used for either interior or exterior doors, following the instructions of the manufacturer. |

| Technology description including background system | The production of a push button lock normally follows a 3 step procedure: 1. Prefabrication of the semi- finished products, 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) The individual parts of the product are assembled manually. Technical data: No classes are defined as no EN or national standard is available. 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) |
