This European Standard provides guidance, and where appropriate defines procedures, for variations of certain parameters and factors associated with the design of internal and external loadbearing walls that have been tested in accordance with EN 1365-1. Data from historic standard fire resistance tests may be used as supporting information. Manufactured stone masonry units according to EN 771-5 and natural stone units according to EN 771-6 are not covered. This European Standard is not valid for reinforced masonry.

This document describes a laboratory test method to determine the susceptibility of thermal insulation products used for construction against mould growth under specified climatic conditions. The method is applicable to both factory-made products and in situ formed products. Factory-made products include panels, mats, and rolls. In situ formed products are usually those that are delivered loose and installed by blowing-in, poring, or spraying-on, using water and/or binder, whether or not they are also treated using additives. Depending on the insulation manufacturer, the test is carried out with one of the conditions in Table 1. This condition is linked to worst case scenarios selected from real hygrothermal conditions that reflect the end use conditions experienced by insulation products, and to short test duration for mould test. This test method determines the susceptibility of a thermal insulation material to mould growth, but does not determine the suitability for use in a given design (wall, roof, etc.). This method does not predict the resistance of an insulation product to accidental water exposure resulting in saturation of the product (water damage).

This part of EN 508 specifies requirements for self-supporting products for roof covering, wall cladding, lining, liner tray and tile products for discontinuous laying made from stainless steel sheets with or without additional metallic and/or organic coatings. Sheets intended to be used with insulation and membranes are also covered.
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 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, liner trays and tile products 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 1993-1-3), it does not cover products used in constructions of structural classes I and II (according to EN 1993-1-3) intended to contribute to the global or partial stability of the building structure by providing racking resistance or resistance to permanent static loads (excluding self-weight of the metal sheet).
No requirements for supporting construction, design of roof or cladding, lining, tile system and execution of connections and flashings are included.

1.1 Scope of prEN 1998-1-1 (1) This document is applicable to the design and verification of buildings and other structures in seismic regions. It gives general rules relevant to all types of structures, with the exception of special structures. NOTE Special structures belong to consequence class CC4, which is not fully covered by the Eurocodes. The categories of structures of consequence class CC4 where EN 1998, or parts of it, apply in a country can be provided by the relevant Authorities or can be found in the National Annex. (2) This document provides basic performance requirements and compliance criteria applicable to buildings and civil engineering works in seismic regions. (3) This document gives rules for the representation of seismic actions and the description of the design seismic situations. Certain types of structures, dealt with in other parts of EN 1998, need supplementary rules which are given in those relevant Parts. (4) This document contains general methods for structural analysis and verification under seismic actions, including base-isolated structures and structures with distributed dissipative systems. (5) This document 1 contains rules for modelling and verification of ultimate strengths and deformations. 1.2 Assumptions (1) The general assumptions of prEN 1990:2021, 1.2, are supplemented as given in (2) to (6). (2) It is assumed that no change in the structure and in the masses carried by the structure will take place during the construction phase or during the subsequent life of the structure with respect to the design unless proper justification and verification is provided. This applies to ancillary elements as well (see 3.1.2). Due to the specific nature of the seismic response, this applies even in the case of changes that lead to an increase of the structural resistance. (3) The design documents are assumed to indicate the sizes, the details and the properties of the materials of the structural members. If appropriate, the design documents are also assumed to include the properties of special devices to be used and the distances between structural and ancillary elements. The necessary quality control provisions are assumed to be specified. (4) Members of special structural importance requiring special checking during construction are assumed to be identified on the design documents. In this case, the verification methods to be used are also assumed to be specified. (5) In case of high seismic action class (4.1.1(4)), formal quality system plans, covering design, construction, and use, additional to the control procedures prescribed in the other relevant Eurocodes, are assumed to be specified.
