14、s a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represe
15、nted on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are d
16、rafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International
17、Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10904 was prepar
18、ed by Technical Committee ISO/TC 77, Products in fibre reinforced cement. This first edition of ISO 10904 cancels and replaces ISO 9384:1991 and ISO 9933:1995, which have been technically revised. BS ISO 10904:2011ISO 10904:2011(E) ISO 2011 All rights reserved vIntroduction The performance of a roof
19、 or another building part constructed with the products covered by this International Standard depends not only on the properties of the products as required by this International Standard, but also on the design, construction and installation of the components as a whole relative to the environment
20、 and the conditions of use. This International Standard does not include calculations with regard to works, design requirements, installation techniques, wind uplift or rain proofing of the installed sheets.

21、ts reserved 1Fibre-cement corrugated sheets and fittings for roofing and cladding 1 Scope This International Standard specifies technical requirements and methods for the inspection and testing of straight short and long fibre-cement profiled sheets and their fibre-cement fittings designed to provid
22、e the weather-exposed surfaces on roofs and internal and external walls of buildings. Products covered by this International Standard can be used for other purposes, provided they comply with the appropriate national or international application code or standard. Some of the requirements of this Int
23、ernational Standard can apply, after agreement between manufacturer and purchaser, to curved profiled sheets. The type tests described in this International Standard are not intended to evaluate the performance of the coating in isolation (colour-fastness, adhesion, etc.). Specific performance requi
24、rements for coatings are referenced in other International Standards or national standards. This International Standard does not apply to fibre-cement profiled sheets and fittings reinforced with asbestos fibres. 2 Normative references The following referenced documents are indispensable for the app

NOTE 2 Test
31、 methods, specifications and limit values are specified in this International Standard. Sampling levels and acceptance criteria are specified in 6.3. NOTE 3 See ISO 390. 3.4 type test test performed to demonstrate conformity with the requirements of this International Standard or for the approval of
32、 a new product and/or when a fundamental change is made in formulation and/or method of manufacture, the effects of which cannot be predicted on the basis of previous experience NOTE The test is performed on the as-delivered product, but is not required for each production batch. 3.5 acceptable qual
33、ity level AQL maximum percent defective (or maximum number of defects per 100 units) that can be considered satisfactory as a long-term average quality level in a sampling plan NOTE When a manufacturers process satisfies a sampling scheme with an AQL of 4 %, this indicates that 96 % of the inspected
34、 product exceeds the specification. This type of specification provides the consumer with a clearly defined lower quality boundary; this does not occur if acceptance is based solely on the average value of the measured property. Examples of sampling schemes can be found in ISO 390, ISO 2859-1 and IS
