| Use advice for data set | The life cycle assessment of the SNX300, an EEPS (Electronic and Electrical Products and Systems), is a “cradle-to-grave” analysis. Below table shows the product life cycle stages, and the information considered in the LCA. Life cycle stages of the product in the LCA In terms of exclusions from the system boundary, according to PCR, capital goods such as machinery, tools, buildings, infrastructure, packaging for internal transports, and administrative activities, which cannot be allocated directly to the production of the reference product, are excluded. Infrastructures, when present, such as in processes deriving from the ecoinvent database, have not been excluded. Scraps for metal working and plastic processes are also included when already defined in ecoinvent. |
| Technical purpose of product or process | This Environmental Product Declaration is a “specific product EPD”, and the declared product is the SNX300, including related packaging. The SNX300 is a series of environmental temperature and humidity sensors and controllers which support Modbus RTU protocol over an RS485 interface. While SNX301 is a pure temperature and humidity sensor, SNX302 can act stand-alone or remotely connected to M&D concentrator, to control a local heater to prevent moisture based on dew point calculation. This EPD is based on SNX302 as reference workflow and with sensitivity analysis the environment impact of SNX301 is also further discussed, thus this EPD covers the SNX300 series products, including related packaging. General technical information of the SNX300 is presented below. Description Values Size Width 45.6 mm Height 30.0 mm Length 74.8 mm Weight SNX301 62 g SNX302 69 g Basic parameters Voltage input 9…28 VDC Measuring range -40…80 ?, 0…100% RH Accuracy Temperature: ±1 ? Humidity: ±4% RH Response period Temperature: 5…30 s (t63%) Humidity: <8s (t63%, 25 ? and 1 m/s airflow) Operating temperature range -40…80 ? The SNX300 is owned by ABB Xiamen Switchgear Co., Ltd. (ELDS division), which specializes in the production, sales, and service of 3.6kV – 40.5kV switchgears and circuit breakers and related intelligent components for smart systems and technologies for electrical distribution supplied to utilities, industrial, and tertiary sector customers. ABB ELDS division, China adopts and implements for its own activities an integrated Quality/Environmental/Health Management System in compliance with the following standards: • ISO 9001:2015–Quality Management Systems • ISO 14001:2015–Environmental Management Systems • ISO 45001:2018–Occupational Health and Safety Management Systems • ISO 50001:2018–Energy management systems The SNX300 is manufactured by ABB supplier WE (Wisdom Electronics) located in Xiamen, China. The manufacturing site is certified according to the following standards: • ISO 9001:2015 – Quality Management Systems • ISO 14001:2015 – Environmental Management Systems The constituent materials of SNX302 are presented below.

| General comment on data set | Both primary and secondary data are used. The main sources for primary data are the bill of materials (BOM), CAD-files, technical drawings, and site-specific foreground data provided by ABB. Secondary raw material contents are also considered, which is provided by the suppliers for the main materials. For all processes for which primary data are not available, generic background data originating from the ecoinvent v3.9.1 database, with system model “allocation, cut-off by classification”, are used. The database Industry Data 2.0 is also used for chemical substance which is not available by ecoinvent. The LCA software used for the calculations is SimaPro 9.5. The utility consumption and waste generation by ABB, in the core manufacturing stage, is allocated to the production of one reference product according to applicable rules. For the end-of-life allocation, the “Polluter Pays” principle is adopted according to what is defined in the CEN/TR 16970 standard. However, the potential benefits and avoided loads from recovery and recycling processes are not considered because it is not required by the PCR. No cut-off criteria were applied to exclude materials from the calculation. |
