SIST EN 16578:2016

EN 16578:2016 (E) 3 European foreword This document (EN 16578:2016) has been prepared by Technical Committee CEN/TC 163 “Sanitary appliances”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2016, and conflicting national standards shall be withdrawn at the latest by August 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supports the unified approach for the assessment of sustainability of ceramic sanitary appliances, i.e. WC pans and WC suites, urinals, wash basins, bidets and communal washing troughs, in the light of the document CPR 06/10/1 of European Commission - Enterprise and Industry - Sustainable Industrial Policy and Construction. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 16578:2016

EN 16578:2016 (E) 4 Introduction This European Standard supports the (harmonized) European Standards on ceramic sanitary appliances elaborated by CEN/TC 163 on assessing the sustainability for these products. This European Standard provides a system for sustainability assessment of ceramic sanitary appliances using a life cycle approach, featuring qualitative and quantitative indicators for ecologic, economic and social performance of sanitary ceramic appliances. The purpose of this European Standard is to provide requirements and classification values for the assessment of the sustainability of ceramic sanitary appliances. Selected parameters assessed in accordance with this standard represent the main parameters defined in EN 15804. This European Standard may be used to support environmental building assessment and environmental product declarations (EPDs). The structure and the parameters of EN 15804 mandatory requirements from information modules A1 to A3 - are used as a basis for the ecological criteria of this European Standard. A system with sustainability classes has been introduced to express the performance of ceramic sanitary appliances. The link between these classes and the assessment of the products form a framework of evaluation schemes. Evaluation schemes enable the comparison of different ceramic sanitary appliances. NOTE EPDs based on EN 15804 are not comparative assertions (see EN 15804:2012+A1:2013, 5.1). These EPDs are necessary for environmental assessment of building only. SIST EN 16578:2016

These “three pillars” (ecological, economic and social requirements) are generally used in terms of sustainability. NOTE 1 Pillar 1 “Ecological requirements” covers the applicable requirements from information modules A1 to A5 of EN 15804. Pillar 2 “Economical requirements” covers the applicable requirements from information modules B1, B6 and B7 of EN 15804. SIST EN 16578:2016

EN 16578:2016 (E) 9 Pillar 3 “Social requirements” covers further applicable requirements from information modules B2 to B5 of EN 15804. This clause describes the detailed criteria and defines the requirements for the evaluation of the sustainability of ceramic sanitary appliances. NOTE 2 The assessment of ceramic sanitary appliances is based on applicable product category rules in accordance with EN 15804. The assessment shall be carried out per production site or per defined group/network of production sites (see Annex A). The assessment shall take into account at least 90 % of each input or output of material(s) or energy and a correction to 100 % shall be made for each value. For example for 4.2.2.1: In case of 95 % assessed renewable energy consumption, then also 95 % of the production mass shall be taken into account. The assessment period shall cover a period of 12 subsequent months. All parameters shall be determined within the same assessment period. All values for calculating the parameter of the various criteria are to be based on the assessment period, e.g. Wt is the total production mass over the assessment period. The assessment is valid for the following 5 years maximum. For the purposes of assessment, the manufacturer's products may be grouped into families, where it is considered that the results for the assessed characteristics from any one product within the family are representative for the same characteristics for all products within that same family, e.g. WC of type 5, WC of type 6, WCs suites of type 6 or wash basins. The evaluated result for each requirement shall be reported in the evaluation scheme in Annex B. In the case when a requirement is not applicable for one product or product group, e.g. flush volume for wash basins, it has to be given “not applicable” for non-applicability into the respective line of the fields “value” and “rating”. This assessment may be used to support environmental building assessment. 4.2 Ecological criteria 4.2.1 General The ecological pillar covers the preservation of resources. For ceramic sanitary appliances, sustainability means optimised use of resources; optimized exploitation of raw materials, (energy-) optimised production and optimised transport (delivery chain). Statements in 4.2.2 to 4.2.4 cover the relevant ecological criteria for the cradle to gate stage. They take into account raw material extraction and processing, processing of secondary material input (e.g. recycling processes), transport to the manufacturer, manufacturing, including provision of all materials, products and energy, as well as waste processing up to the end-of waste state or disposal of final residues during the product stage including the relevant characterization factors, where applicable. The ecological criteria described in 4.2.5 concerns the construction process consisting of transport and installation. NOTE Characterization factors are taken from database CML-IA, version 4.1 of October 2012 from Institute of Environmental Sciences, Leiden University (NL) or equivalent or the attachment A1:2013 of EN 15804:2012. Further not mentioned characterization factors are available in amendments of EN 15804:2012, e.g. EN 15804:2012+A1:2013. When assessing the ecological criteria, parameters are declared per ton (1 000 kg) of ceramic sanitary ware. SIST EN 16578:2016
