European foreword
This document (prEN 17662:2021) has been prepared by Technical Committee CEN/TC 135 “Execution
of steel structures and aluminium structures”, the secretariat of which is held by SN.
This document is currently submitted to the CEN Enquiry.
Introduction
As in EN 15804:2012+A2:2019, in addition:
This European Standard provides rules for Environmental Product Declarations (EPD) for steel and
aluminium structural elements which are used in buildings and civil engineering works. It complements
the core product category rules for all construction products and services as established in
EN 15804:2012+A2:2019.
This document:
• gives precision to the material specific system boundaries, including mandatory modules C and D
• specifies the use of modules A1 and A3
• gives precision to when and where to include impact from coatings
• gives precision to when and how to report additional indicators
• gives precision to allocation procedures for multi-output processes along the steel and aluminium
manufacturing process chain
• gives precision to allocation procedures for re-use and recycling
• provides in Annexes G, H, and I, default data and scenarios for transport, reuse and re-cycling, and
erection/deconstruction
• gives guidance in Annex L for downstream companies on how to use an Environmental Product
Declaration, EPD, from a supplier
1 Scope
This document provides product category rules (c-PCR), that are complementary to
EN 15804:2012+A2:2019, for Type III environmental declarations for steel components and aluminium
components fabricated from steel or aluminium constituent products to be used for structural purposes
in buildings and civil engineering works, where their characteristic affects the mechanical resistance
and stability of these construction works or parts thereof. The structures can be built-in structures or
open structures. This document also provides guidance for other metal construction products where a
specific PCR as EN standard does not exist.
This document is intended to be used in conjunction with EN 15804:2012+A2:2019.
This document can be used also for non-structural metal products or metal parts thereof where a
specific PCR as EN standard does not exist.
This document is intended to be used for cradle-to-gate with options or cradle to grave assessment,
provided the intention is properly stated in the system boundary description.
The assessment of social and economic performances at product level is not covered by this standard.

3.1
recycled metals
metals produced from secondary materials which substitutes primary materials
Note 1 to entry: E.g. recycled metal ingot or slab.
Note 2 to entry: Recycled metals are typically produced from metal scrap which are secondary materials for
recycling. The fraction of recycled metal within a product can vary from low proportion to high depending on the
sourcing of its production, e.g. fraction of virgin metal vs fraction of metal scrap.
3.2
reused metal products and metal components
products or components recovered from previous use which substitutes new products/components
Note 1 to entry: Examples of reused metal products and metal components a
