This document provides product category rules (PCR) for Type III environmental declarations for rooflights and roof hatches to be used on upstands in flat and slightly inclined roofs. This document complements the core rules for the product category of construction products as defined in [1]. This document is used in conjunction with [1] and does not replace it. The core PCR: — defines the parameters to be declared and the way in which they are collected and reported; — describes 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; — defines rules for the development of scenarios; — includes 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; — includes the rules for reporting the predetermined, environmental and health information that is not covered by Life Cycle Assessment (LCA) for the product, construction process(es) and construction service(s), as relevant; — defines 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. This document applies to rooflights and roof hatches with upstands as well as rooflights and roof hatches supplied without an upstand, intended for use on upstands. The rooflights and roof hatches may be individual or continuous types. The main purpose of rooflights is to transmit daylight into the building. Roof hatches provide mainly access to the roof. But beside their primary purposes these products can be used for different additional functions e.g. — natural ventilation; — fire compartmentation and smoke control; — emergency exit; — natural smoke and heat exhaust ventilation in accordance with [2]. So the functions and the products are not fixed linked to each other. Construction products covered by these complementary product category rules are: — individual rooflights and individual rooflights with upstands; — roof hatches; — continuous rooflights and continuous rooflights with upstands.
This document specifies requirements for roofing and cladding products used for assembly into coverings for wall claddings, linings and pitched roofs, made from aluminium sheet with or without additional surface treatment (organic coating or anodising). This document establishes general characteristics, definitions and labelling of the products, together with requirements for the materials from which the products can be manufactured. It is intended to be used either by manufacturers to ensure that their products comply with the requirements or by purchasers to verify that the products comply before they are despatched from the factory. It specifies the requirements for products which enable them to meet all normal service conditions. Products can be prefabricated or semi-formed products as well as strip, coil and sheet for on-site-formed applications (e.g. standing seam roofs). This document applies to all discontinuously laid and fully supported roofing and cladding products made of aluminium sheets. No requirements for supporting construction, design of roof system and execution of connections and flashings are included. This document does not apply to self-supporting aluminium sheets that are covered by EN 508-2:-.
This part of EN 508 specifies requirements for self-supporting external profiled sheets for roof covering, wall cladding, lining and liner tray products for discontinuous laying made from aluminium sheet with or without surface treatment (additional organic coatings or anodising). This document establishes general characteristics, definitions, classifications and labelling for the products, together with requirements for the materials from which the products can be manufactured. It is intended to be used either by manufacturers to ensure that their products comply with the requirements or by purchasers to verify that the products comply before they are made available on the market before being dispatched from the factory. It specifies the requirements for products which enable them to meet all normal service conditions. This document applies to all discontinuously laid self-supporting external profiled sheets for roof covering, wall cladding, lining and liner trays with the exception of tiles with a surface area less than 1 m2 and produced by stamping. These profiled roof sheets are designed to keep wind, rain and snow out of the building, and to transfer any resultant loads and infrequent maintenance loads to the structure. This document does not cover products for structural purposes, i.e. it does cover products used in structural class III (according to EN 1999 1 4), it does not cover products used in constructions of structural classes I and II (according to EN 1999 1 4) intended to contribute to the global or partial stability of the building structure by providing racking resistance or resistance of permanent static loads (excluding self-weight of the metal sheet). No requirements for supporting construction, design of roof or cladding system and execution of connections and flashings are included.
