Round and sawn timber - Environmental product declarations - Product category rules for wood and wood-based products for use in construction

Edition date: 2026-04-08
In Force
Available languages: English
Summary: This document provides general product category rules (PCR) for Type III environmental declarations for wood and wood-based products, including wood-based panels, for use in construction and related construction and in-service processes. This document complements the core rules for the product category of construction products as defined in EN 15804 and is intended to be used in conjunction with EN 15804. This document does not cover the assessment of social and economic performances at product level. The core PCR: — define the parameters to be declared and the way in which they are collated and reported; — describe which stages of a product’s life cycle are considered in the EPD and which processes are to be included in the life cycle stages; — define rules for the development of scenarios; — include the rules for calculating the life cycle inventory and the life cycle impact assessment underlying the EPD, including the specification of the data quality to be applied; — include the rules for reporting predetermined, environmental and health information, that is not covered by LCA for a product, construction process and construction service where necessary; — define the conditions under which construction products can be compared based on the information provided by EPD. For the EPD of construction services, the same rules and requirements apply as for the EPD of construction products. Additionally, to the common parts of EN 15804, this document for wood and wood-based products: — defines the system boundaries; — defines the rules for modelling and assessment of material-specific characteristics such as carbon content and net calorific value of wood; — defines allocation procedures for multi-output processes along the wood chain; — defines allocation procedures for reuse, recycling and energy recovery; — includes the rules for calculating the life cycle inventory and the life cycle impact assessment underlying the EPD, including the assessment of carbon and net calorific value of wood; — provides guidance/specific rules for the determination of the reference service life (RSL).

Le présent document fournit les règles de définition des catégories de produits (RCP) générales pour les déclarations environnementales de Type III relatives aux produits en bois et dérivés du bois, y compris les panneaux à base de bois, destinés à être utilisés dans la construction et les services de construction associés à ces produits. Le présent document vient compléter les règles régissant les catégories de produits de construction définies dans l'EN 15804 et est destiné à être utilisé conjointement avec l'EN 15804. Le présent document ne couvre pas l'évaluation des performances sociales et économiques au niveau des produits. Le tronc commun des RCP: — définit les paramètres à déclarer et la manière dont ils sont regroupés et consignés; — décrit les étapes du cycle de vie d'un produit prises en compte dans la DEP ainsi que les processus devant être inclus dans les étapes du cycle de vie; — définit les règles relatives à l'élaboration de scénarios; — intègre les règles de calcul de l'inventaire du cycle de vie et de l'évaluation de l'impact du cycle de vie servant de base à la DEP, y compris la spécification de la qualité des données à appliquer; — intègre les règles de communication d'informations environnementales et sanitaires prédéterminées, qui ne sont pas couvertes par l'analyse du cycle de vie, pour un produit, un processus de construction et un service de construction, si nécessaire; — définit les conditions dans lesquelles les produits de construction peuvent être comparés, sur la base des informations fournies par la DEP. Les règles et les exigences applicables à la DEP des services de construction sont les mêmes que pour la DEP des produits de construction. Outre les parties communes de l'EN 15804, le présent document relatif aux produits en bois et dérivés du bois:  définit les frontières du système;  définit les règles pour la modélisation et l'évaluation de caractéristiques spécifiques du matériau telles que la teneur en carbone et le pouvoir calorifique inférieur du bois;  définit des procédures d'affectation applicables aux processus multidébouchés de l'ensemble de la filière bois;  définit des procédures d'affectation applicables à la réutilisation, au recyclage et à la récupération d'énergie;  intègre les règles de calcul de l'inventaire du cycle de vie et de l'évaluation de l'impact du cycle de vie servant de base à la DEP, y compris l'évaluation du carbone et du pouvoir calorifique inférieur du bois;  fournit des recommandations/règles spécifiques pour la détermination de la durée de vie de référence (DVR).

Dieses Dokument stellt allgemeine Produktkategorieregeln (PCR, en: product category rules) für Typ-III-Umweltdeklarationen für Produkte aus Holz und Holzwerkstoffen auf, einschließlich Holzwerkstoffplatten, zur Verwendung in Bauwerken und die damit zusammenhängenden Bauverfahren und Dienstleistungen. Dieses Dokument ergänzt die Grundregeln für die Produktkategorie sämtlicher Bauprodukte, wie in EN 15804 festgelegt, und ist dazu vorgesehen, in Verbindung mit EN 15804 angewendet zu werden. Die Beurteilung der sozialen und ökonomischen Leistungen auf der Produktebene ist nicht Gegenstand dieses Dokuments. Die grundlegenden PCR:  legen die zu deklarierenden Parameter und die Art fest, wie sie auf Vollständigkeit überprüft und kommuniziert werden;  beschreiben, welche Phasen des Lebenszyklus eines Produktes in der EPD berücksichtigt werden und welche Prozesse in die Phasen des Lebenszyklus einzubeziehen sind;  legen die Regeln für die Entwicklung von Szenarien fest;  umfassen die Regeln zur Berechnung der Sachbilanz und der Wirkungsabschätzung, die einer EPD zugrunde liegen, einschließlich der Festlegung der zu verwendenden Datenqualität;  umfassen die Regeln für die Kommunikation vorgegebener Umwelt- und Gesundheitsinformationen, die für ein Bauprodukt, einen Bauprozess oder eine Bauleistung nicht von einer Ökobilanz (LCA, en: life cycle assessment) abgedeckt sind, soweit erforderlich;  legen die Bedingungen fest, unter denen Bauprodukte auf der Basis der Informationen aus der EPD verglichen werden können. Für die EPD von Bauleistungen sind dieselben Regeln und Anforderungen wie für die EPD von Bauprodukten anwendbar. Zusätzlich zu den allgemeinen Teilen der EN 15804 legt dieses Dokument zu Produkten aus Holz und Holzwerkstoffen Folgendes fest:  die Systemgrenzen;  die Regeln für die Modellierung und Beurteilung von werkstoffspezifischen Eigenschaften wie etwa Kohlenstoffgehalt und spezifischer Heizwert von Holz;  die Zuordnungsverfahren (Allokationsverfahren) für Prozesse mit mehreren Outputs entlang der Holzverarbeitungskette;  die Zuordnungsverfahren (Allokationsverfahren) für die Wiederverwendung, das Recycling und die Energierückgewinnung;  die Regeln zur Berechnung der Sachbilanz und der Wirkungsabschätzung, die einer EPD unterliegen, einschließlich der Abschätzung des Kohlenstoffgehaltes und des spezifischen Heizwertes von Holz;  eine Anleitung/besondere Regeln für die Festlegung der Referenz-Nutzungsdauer (RSL, en: reference service life).
