The objective of the ISO 15928- series is to identify the methods that will be used to describe the performance of houses.
16、 The ISO 15928- series is confined to buildings occupied for residential purposes that may be separated or linked horizontally, but not linked vertically, and which have their own access and do not share any common space. Each part of ISO 15928 relates to a separate attribute. The parts of ISO 15928
17、 do not specify levels of performance and they are not intended to replace national standards or regulations, but provide a standardized framework to be used for development of national standards and regulations consistent with World Trade Organization (WTO) requirements. The parts of ISO 15928 do n
18、ot provide design methods and/or design criteria. Based on the framework provided by the ISO 15928- series, purchasers, regulators and standards- preparers in respective countries can describe their requirements in standardized performance terms, as appropriate. Additionally, the manufacturers/provi
19、ders can respond by describing the performance of their products in a similar manner. The purpose of this part of ISO 15928 is to provide a standardized system of describing performance that can be used to specify performance requirements and performance levels, or to rate houses, in terms of struct
20、ural durability. NOTE The WTO Agreement on technical barriers to trade, Clause 2.8, states: “Whenever appropriate, members shall specify technical regulations based on product requirements in terms of performance, rather than design or descriptive characteristics.” ISO 2015 All rights reserved v Hou
21、ses Description of performance Part 3: Structural durability 1 Scope This part of ISO 15928 sets out a method for describing the structural durability performance of houses. It covers objectives, provides performance descriptions, establishes parameter descriptions and outlines evaluation processes.
22、 This part of ISO 15928 is intended for use in the evaluation of the design and construction of houses, in the international trading of houses or their subsystems and in developing quality systems for houses. The ISO 15928- series does not specify a level of performance and it is not intended to pro
23、vide a design method and/or criteria. NOTE 1 Annex A includes background information on this part of ISO 15928, guidance on its use and suggestions on good practice. NOTE 2 Details on references referred to in Notes are provided on Bibliography. NOTE 3 Structural safety, serviceability and other att
24、ributes are covered in other parts of ISO 15928. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest editio

26、ti ons For the purposes of this document, the terms and definitions given in ISO 6707-1, ISO 2394, ISO 13823 and the following apply. 3.1 components part of a house that can be identified EXAMPLE Floor, wall. Note 1 to entry: Includes fittings. 3.2 house building occupied for residential purposes an
27、d designed as one unit (dwelling) with its own access Note 1 to entry: The house can be a separate building, or linked horizontally with another house but not linked vertically. INTERNATIONAL ST ANDARD ISO 15928-3:2015(E) ISO 2015 All rights reserved 1 ISO 15928-3:2015(E) Note 2 to entry: Where hous
28、es are linked, each has its own access and does not share any space in common with another. Note 3 to entry: Where houses are linked, services including those related to energy usage and supply, heating and ventilation may be shared. Note 4 to entry: Where houses are linked, the wall between the hou
29、ses is typically designed and constructed to limit the probability of fire spread between houses. Note 5 to entry: See ISO 6707-1:2014, 3.1.3 for the definition of building. 3.3 maintenance schedule series of actions and time intervals between these actions to maintain the levels of structural safet
30、y and serviceability performance of the whole house over the service life 3.4 parameters structural durability group of variables used to quantitatively describe the structural durability performance 3.5 performance behaviour of houses related to use 3.6 service life period of time after installatio
31、n during which a house or its components meet or exceed the structural safety and serviceability performance requirements 4 Structural durability performance 4.1 Objective The structural durability performance of a house which may affect the occupants, the functioning of the house and/or property da
32、mage, shall be such that its service life and the necessary maintenance schedules for the house as a whole and for its components shall be acceptable to the user. 4.2 Performance descriptions The performance description for structural durability is the ability of the whole house and its parts, with
33、an appropriate degree of reliability, to fulfil its intended structural safety and serviceability performance in the environment in which it is located over the service life when subject to its intended use. The structural durability performance can be expressed in terms of: a) the service life of t
34、he house as a whole; b) component service life including accessibility consideration for inspection, repair or replacement; c) the maintenance schedules required to achieve the service life of the house as a whole and/or its components as appropriate; d) internal and external environmental agents th
35、at are likely to occur in the house service life.2 ISO 2015 All rights reserved ISO 15928-3:2015(E) 5 Parameters for the description of performance 5.1 Parameters for describing the house service life The house service life shall be described in terms of years that the house is expected to be in use
36、. 5.2 Parameters for describing component service life The component service life (if less than that of the house) shall be described in terms of years, between the replacement of structural components under the maintenance schedule. Accessibility of components for inspection, repair or replacement
37、shall be described. 5.3 Parameters for describing the maintenance schedule The maintenance schedule shall be described by specifying all technical and administrative actions and their frequencies during the service life to keep the house or its components capable of performing their required functio
38、n. NOTE Guidance on parameters required can be found in ISO 15686-5, (5.4.2). 5.4 Parameters for describing internal and external environmental agents 5.4.1 General The parameters for describing internal and external environmental agents considered relevant to the structural durability are: a) the g
39、eographical location of the house; b) agents causing environmental actions. 5.4.2 Parameters for geographical location The parameters for describing geographical location include: a) the distance from a coast-line, other geographical features or sources of pollutants; b) the climate zone; c) the phy
40、sical location, e.g. latitude and longitude. 5.4.3 Parameters describing agents causing environmental actions The following agents shall be considered if appropriate: a) moisture and contaminants; b) air and contaminants; c) soil and ground contaminants; d) biological agents; e) temperature; f) sola
41、r radiation; g) incompatible chemicals; ISO 2015 All rights reserved 3 ISO 15928-3:2015(E) h) use or exposure. NOTE Environmental action can also occur as the result of a self-aging process. Where appropriate, the following parameters should be used to quantify these influences: duration of wetness;
42、 duration of exposure; freezethaw cycles; temperature; pH value for acidity; concentration of chemicals and contaminants. An assessment should be made as to whether these influences act either individually or in combination. 6 Evaluation 6.1 General ISO 13823 describes the following two procedures f
43、or the evaluation of structural durability performance: a) Service life format: This procedure consists of ensuring that the predicted structural design life of a whole house or component, allowing for variations in durability, equals or exceeds the specified design life of the house or component. b
44、) Limit state format: This procedure consists of ensuring that, at all the times during the specified design life of the whole house or component, the performance requirements for structural safety and serviceability are satisfied. 6.2 Evaluation methods 6.2.1 General Performance or properties for b
45、oth whole house and components and material over time for a specified environment and maintenance schedule can be determined by: a) field testing; b) laboratory (accelerated) testing; c) service experience; d) modelling. Experience shall be used only for identical component and in the same environme
46、nt. Modelling and experience shall be used for (i) similar component in the same environment or (ii) identical components in moderately different environments. Modelling and testing (field or laboratory) shall be used for (i) innovative components or (ii) identical components in significantly differ
47、ent environments.4 ISO 2015 All rights reserved ISO 15928-3:2015(E) 6.2.2 Field testing Full-scale dwellings, assemblies, components or materials in dwellings can be exposed to a real environment for a stipulated length of time prior to the determination of structural safety or serviceability perfor
48、mance. It is necessary that scientifically justified principles be used to relate the performance after the exposed time to that at the service life as appropriate. NOTE Guidance on the relevant principles can be found in ISO 15686-1 and ISO 15686-2. 6.2.3 Laboratory testing Accelerated ageing in la
49、boratory facilities may be used for all testing (whether for whole dwellings, components, assemblies or materials) prior to the determination of structural safety or serviceability performance in accordance with the methods in ISO 15686-1, ISO 15686-2 and ISO 15686-8. It is necessary that scientifically justified principles be used to relate the performance in the laboratory test to that in reality. 6.2.4 Service experience Service experience may be used in the assessment of the working life either of the wh
