DIN EN 16757 PDF Download

The DIN EN 16757 standard is a European standard that complements the core rules for the product category of construction products. It is designed to be used in conjunction with the EN 15804+A1 standard.

This standard specifically applies to concrete and concrete elements used in building and civil engineering projects. It establishes parameters for reporting, identifies the types of Environmental Product Declarations (EPDs) and life cycle stages to be covered, and outlines the rules for generating Life Cycle Inventories (LCI) and conducting Life Cycle Impact Assessment (LCIA). It also sets guidelines for data quality in the development of EPDs.

In addition to the common parts of the EN 15804+A1 standard, DIN EN 16757 for concrete and concrete elements defines the system boundaries, addresses material-specific characteristics in modeling and assessment, establishes procedures for allocation in multi-output processes along the production chain and for reuse and recycling, and provides guidance on calculating the LCI, LCIA, and reference service life (RSL) underlying the EPD. It also offers guidance on default scenarios and functional units for concrete elements.

This standard allows for different assessment approaches, including cradle to gate, cradle to gate with options, and cradle to grave, as long as the intentions are clearly stated in the description of the system boundary. By providing a comprehensive understanding of the environmental impact associated with concrete and concrete elements throughout their life cycle, a cradle to grave declaration can contribute to the assessment of sustainability in construction works.
