1.1 Scope of EN 1991 1 2 (1) The methods given in this Eurocode are applicable to buildings and civil engineering works, with a fire load related to the building and its occupancy. (2) EN 1991 1 2 deals with thermal and mechanical actions on structures exposed to fire. It is intended to be used in conjunction with the fire design Parts of EN 1992 to EN 1996 and EN 1999 which give rules for designing structures for fire resistance. (3) EN 1991 1 2 contains thermal actions either nominal or physically based. More data and models for physically based thermal actions are given in annexes. (4) EN 1991 1 2 does not cover the assessment of the damage of a structure after a fire. (5) EN 1991 1 2 does not cover supplementary requirements concerning, for example: - the possible installation and maintenance of sprinkler systems; - conditions on occupancy of building or fire compartment; - the use of approved insulation and coating materials, including their maintenance. 1.2 Assumptions (1) In addition to the general assumptions of EN 1990 the following assumptions apply: - any active and passive fire protection systems taken into account in the design will be adequately maintained; - the choice of the relevant design fire scenario is made by appropriate qualified and experienced personnel, or is given by the relevant national regulation.

1.1 Scope of prEN 1996 3 (1) The scope of EN 1996-1-1 applies also to this this document. (2) This document provides simplified calculation methods to facilitate the design of the following unreinforced masonry walls, subject to certain conditions of application: - walls subjected to vertical and wind loads; - walls subjected to concentrated loads; - shear walls; - basement walls subjected to lateral earth pressure and vertical loads; - walls subjected to lateral loads but not subjected to vertical loads. NOTE For those types of masonry structures or parts of structures not covered by (2), the design can be based on EN 1996-1-1. (3) The rules given in this document are consistent with those given in EN 1996-1-1, but are more conservative in respect of the conditions and limitations of their use. (4) The rules given in this document assume that concrete floors are designed according to EN 1992 1 1. (5) This document applies only to those masonry structures, or parts thereof, that are described in EN 1996-1-1 and EN 1996-2. (6) The simplified calculation methods given in this document do not cover the design of double-leaf walls. (7) The simplified calculation methods given in this document do not cover the design for accidental situations. 1.2 Assumptions (1) The assumptions of EN 1990 apply to this document.

(1) This document defines imposed loads (models and representative values) associated with road traffic, pedestrian actions and rail traffic which include, when relevant, dynamic effects and centrifugal, braking and acceleration actions and actions for accidental design situations. (2) Imposed loads defined in this document are applicable for the design of new bridges, including piers, abutments, upstand walls, wing walls and flank walls, noise barriers, canopies etc., and their foundations. Where appropriate, the loads can also be considered as a basis for assessment or modification of existing structures in combination with complementary conditions if necessary. (3) The load models and values given in this document are also applicable for the design of retaining walls adjacent to roads and railway lines and the design of earthworks subject to road or rail traffic actions. This document also provides applicability conditions for specific load models. (4) This document is intended to be used with prEN 1990, the other parts of the EN 1991 series and the EN 1992 series to EN 1999 series for the design of structures.

1.1 Scope of prEN 1992 1 2 (1) This document deals with the design of concrete structures for the accidental situation of fire exposure and is intended to be used in conjunction with prEN 1992 1 1 and EN 1991 1 2. This document identifies differences from, or supplements to, normal temperature design. (2) This document applies to concrete structures required to fulfil a loadbearing function, separating function or both. (3) This document gives principles and application rules for the design of structures for specified requirements in respect of the aforementioned functions and the levels of performance. (4) This document applies to structures, or parts of structures, that are within the scope of prEN 1992 1 1 and are designed accordingly. (5) The methods given in this document are applicable to normal weight concrete up to strength class C100/115 and lightweight concrete up to strength class LC50/60. 1.2 Assumptions (1) In addition to the general assumptions of prEN 1990 the following assumptions apply: - the choice of the relevant design fire scenario is made by appropriate qualified and experienced personnel or is given by the relevant national regulation; - any fire protection measure taken into account in the design will be adequately maintained.

This standard gives the general basis for the design of structures in plain, reinforced and prestressed concrete made with normal weight, lightweight and heavyweight aggregates together with specific rules for buildings, bridges and civil engineering structures, including temporary structures, under temperature conditions between –40 °C and +100 °C generally. It complies with the principles and requirements for the safety, serviceability, durability and robustness of structures, the basis of their design and verification that are given in EN 1990 Basis of structural and geotechnical design. EN 1992 is only concerned with the requirements for resistance, serviceability, durability, robustness and fire resistance of concrete structures. Other requirements, e.g. concerning thermal or sound insulation, are not considered. This Part 1-1 does not cover: − resistance to fire (see EN 1992-1-2), − fastenings in concrete (see EN 1992-4), − seismic design (see EN 1998), − particular aspects of special types of civil engineering works (such as dams, pressure vessels), − design with galvanised reinforcing steel, − structures made with no-fines concrete, aerated or cellular concrete, lightweight aggregate concrete with open structure components, − structures containing structural steel sections (see EN 1994 for composite steel-concrete structures), − Structural parts made of concrete with D_lower < 8 mm, unless otherwise stated in the code.

This document provides product category rules (PCR) for Type III environmental product declarations, as described in EN ISO 14025 and EN 15942, for "buried plastics piping systems" intended for buried pressure and non-pressure applications outside building structure. This PCR covers the entire life cycle from cradle to grave for buried plastics piping systems conveying fluids (sewer, water or gas), according to EN 12007, EN 805 or EN 476. NOTE The PCR will be applied to systems composed of products covered by the list of product standards provided in Annex D. This document specifies the rules for the product category of construction products as defined in and is intended to be used in conjunction with EN 15804. As in EN 15804:2012+A2:2019, in addition to the common parts of EN 15804, this document for buried plastics piping systems defines: - the functional unit; - the system boundaries; - the elements of installation; - the transport scenarios for both the raw material and the complete system; - the trench conditions; - reference service life (RSL); - end of life scenarios.
