10、 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 represented on that committee. Internationa

11、l 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 drafted in accordance with the rules g

12、iven 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 Standard requires approval by at least

13、 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 12575-1 was prepared by Technical Committee ISO/TC 163,

16、iers, designers and engineers of insulation systems with guidelines on what properties are to be considered for the thermal insulating materials for a building foundation insulating system where the insulation is in direct contact with ground soils. The designer shall consult the appropriate nationa

17、l regulations and application specifications for minimum requirements.The designer selects the actual material in accordance with this part of ISO 12575 for the type of system to be used in a specific application. The designer also consults the appropriate material standard and national regulations

18、for the material selected for added characteristics not specified in this part of ISO 12575.The manufacturer produces the material according to any applicable material standards, declares that their material type meets the requirements of this part of ISO 12575, declares the fitness for the intended

19、 use, and labels the material according to this part of ISO 12575.The installer follows the requirements of the designer, the manufacturer, local government regulations, ISO 12575-2 and assumes responsibility for installation.Included as part of the development of ISO 12575 (all parts) is the review

20、 of applicable CEN documents; CEN standards were harmonized where appropriate.Moisture control for this application is only partially addressed in the optional requirements in this part of ISO 12575.Calculation methods are addressed in ISO 13793 and ISO 13370.

21、575-1:2012BS ISO 12575-1:2012Thermal insulation products Exterior insulating systems for foundations Part 1: Material specification1 ScopeThis part of ISO 12575 specifies the basic performance requirements for the insulating materials that form part of insulating systems used on the exterior of foun

22、dations and slabs where the insulation is in direct contact with the ground. This part of ISO 12575 does not address exterior insulating systems for foundations permanently immersed in water.Minimum requirements are specified in the appropriate national regulations and application specifications.The

23、 designer selects the actual material in accordance with this part of ISO 12575 for the type of system being considered. The designer also consults the appropriate material standard and national regulations for the product selected for added characteristics not specified in this part of ISO 12575.NO
