13、rvedForeword ISO (the International Organization for Standardization) is 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

14、 a technical committee has been established has the right to be represented 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 mat

15、ters of electrotechnical standardization. International Standards are drafted 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 circu

16、lated to the member bodies for voting. Publication as an International 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 International Standard may be the subject of patent rights. ISO shall not be

17、 held responsible for identifying any or all such patent rights. ISO 9125 was prepared by Technical Committee ISO/TC 77, Products in fibre reinforced cement. This second edition cancels and replaces ISO 9384:1991 1)together with the first edition (ISO 9125:1990), which has been technically revised.

18、It also incorporates the amendment ISO 9125:1990/Amd.1:2004 and the technical corrigenda ISO 9125:1990/Cor.1:1993 and ISO 9125:1990/Cor.2:2005. 1) ISO 9384:1991, Fibre-cement siding shingles. ISO 9125:2009(E) ISO 2009 All rights reserved v Introduction The purpose of this International Standard is t

19、o provide manufacturers and purchasers with uniform requirements for fibre-cement slate products. These requirements are performance based, and have been specified with the objective of ensuring product quality, industry efficiency, and the performance of the product in service. In the development o

20、f this International Standard the technical committee had as an objective the harmonization, where possible, with other national fibre-cement standards, i.e. those of the European Committee for Standardization (CEN), American Society for the Testing of Materials (ASTM), Japanese Industrial Standards

21、 Committee (JIS), to facilitate and promote uniform performance benchmarks for the global use of fibre-cement products. INTERNATIONAL STANDARD ISO 9125:2009(E) ISO 2009 All rights reserved 1 Fibre-cement slates and fittings Product specification and test methods 1 Scope This International Standard s

22、pecifies technical requirements and methods for the inspection and testing of fibre-cement slates and shingles and their fibre-cement fittings, designed to protect the weather-exposed surfaces on roofs and claddings of buildings. Products covered by this International Standard can be used for other

23、purposes provided they comply with the appropriate national or international application code or standard. This International Standard applies to fibre-cement slates with a height dimension not exceeding 850 mm for overlapping assembly (see 5.4). The type tests described in this International Standa

24、rd are not intended to evaluate the performance of the coating in isolation (colour fastness, adhesion, etc.). Specific performance requirements for coatings are referenced in other ISO or national standards. This International Standard does not apply to fibre-cement slates reinforced with asbestos

25、fibres. This International Standard does not include calculations for installation requirements, wind uplift or rain proofing of the installed products. NOTE National standards for installation requirements can be adopted. 2 Normative references The following referenced documents are indispensable f

NOTE 2 Test methods, specificatio

30、ns and limit values are specified in this International Standard. Sampling levels and acceptance criteria are specified in Clause 6. 3.2 acceptable quality level AQL maximum percent defective (or maximum number of defects per 100 units) that can be considered satisfactory as a long-term average qual

31、ity 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 product exceeds the specification. This type of specification provides the consumer with a clearly defined lower quality boundary; this does not occ
