本欧洲标准补充了EN 15804:2012 A1:2013中定义的建筑产品产品类别的核心规则，旨在与该标准配合使用。 本欧洲标准适用于建筑和土木工程的具体和具体要素，不包括高压灭菌加气混凝土。 本文件定义要报告的参数，要覆盖的EPD类型（和生命周期阶段），为了生成生命周期清单（LCI）和进行生命周期影响评估（LCIA）以及数据质量而遵循的规则用于开发EPD。 除了EN 15804:2012 A1:2013的共同部分，本欧洲混凝土和具体要素标准: - 定义系统边界; - 定义材料特性特征的建模和评估; - 定义沿着生产链的多输出过程的分配程序; - 定义重新利用和回收的分配程序; - 包括计算环保署的LCI和LCIA的规则; - 为确定参考使用寿命（RSL）提供指导/具体规则; - 就建立违约情景提供指导; - 为具体要素的默认功能单位提供指导。 T

This European Standard complements the core rules for the product category of construction products as defined in EN 15804:2012+A1:2013 and is intended to be used in conjunction with that standard. This European Standard applies to concrete and concrete elements for building and civil engineering, excluded autoclaved aerated concrete. This document defines the parameters to be reported, what EPD types (and life cycle stages) to be covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs. In addition to the common parts of EN 15804:2012+A1:2013, this European Standard for concrete and concrete elements: - defines the system boundaries; - defines the modelling and assessment of material-specific characteristics; - defines allocation procedures for multi-output processes along the production chain; - defines allocation procedures for reuse and recycling; - includes the rules for calculating the LCI and the LCIA underlying the EPD; - provides guidance/specific rules for the determination of the reference service life (RSL); - gives guidance on the establishment of default scenarios; - gives guidance on default functional units for concrete elements. This document is intended to be used either for cradle to gate, cradle to gate with options or cradle to grave assessment, provided the intentions are properly stated in the system boundary description. Within the construction works context, a cradle to grave declaration delivers a more comprehensive understanding of the environmental impact associated with concrete and concrete elements.
