The work of preparing International Standards is normally carried out through ISO te
12、chnical committees. Each member body interested in a subject for which 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 close
13、ly with the International Electrotechnical Commission (IEC) on all matters 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
14、 International Standards adopted by the technical committees are circulated 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 docume
15、nt may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12574-2 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the built environment, Subcommittee SC 3, Thermal insulation products. ISO 12574
16、consists of the following parts, under the general title Thermal insulation Cellulose-fibre loose-fill for horizontal applications in ventilated roof spaces: Part 1: Material specification Part 2: Principal responsibilities of installers Part 3: Test methodsISO 12574-2:2008(E) ISO 2008 All rights re
17、served v Introduction This part of ISO 12574 specifies the principal responsibilities of installers, as these are common in all countries. It does not specify the application procedures or requirements of the installation, which can vary greatly from one construction to another, from one country to
18、another, or from one jurisdiction in a country to another. This part of ISO 12574 does not conflict with local building codes or labour practices. It serves to clearly delineate the principal responsibilities of the manufacturer of the thermal insulation, which are specified in the material specific
19、ation, from the principal responsibilities of the installer listed in this part of ISO 12574. Because of the uniqueness of the concept of principal responsibilities for the installer, the following general definitions in more than one form are given to assist in translation of the term to other lang
20、uages. Specific definitions are given in Clause 3. a) Principal requirements include the following: 1) procedures that are common to all installations regardless of the construction of the building or the country in which the installation occurs; principal requirements can include instructions to ca
21、rry out a policy statement (meet an objective) but it is not necessarily required to provide a linear progression of steps or actions to be taken; 2) document that provides methods used and that are necessary to accomplish the objective of producing a functional installation. b) Responsibility inclu
22、des the following: 1) condition of being accountable for ones actions; accepting responsibility for ones actions means that the individual who commits an act is the one who is required to explain the act and accept any consequences; 2) condition of being obliged to answer, for ones actions, to an au

24、12574 gives the principal responsibilities of the installers of cellulose-fibre loose-fill thermal insulation products for buildings. If a product is manufactured and packaged according to ISO 12574-1 and then installed in ventilated roof spaces as described in ISO 9774, it is expected to provide th
25、e properties declared by the manufacturer. This part of ISO 12574 gives the principal responsibilities of the installer in the installation of the product, in the documentation of the installation and in the declaration that all requirements of this part of ISO 12574 have been met. This part of ISO
26、12574 does not specify fitness of the product for the intended use beyond those aspects relating to installation. Many aspects relating to the fitness for use are specified in government regulations. It is necessary that the installer ensure, when installing the product, that the product installed i
27、s suitable for the application, based on the government regulations and the manufacturers recommendations. The installer can be required to meet ancillary (additional) requirements that are specified in local regulations or the customers requirements. 2 Normative references The following referenced
