39、(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 a technical comm

40、ittee 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 matters of electrote

41、chnical 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 circulated to the memb

42、er 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 document may be the subject of patent rights. ISO shall not be held responsible for identifyi

43、ng any or all such patent rights. ISO 22475-1 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 341, Geotechnical investigation and testing, in collaboration with Technical Committee ISO/TC 182, Geotechnics, Subcommittee SC 1, Geotechnical investigation and

44、testing, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). ISO 22475-1 consists of the following parts, under the general title Geotechnical investigation and testing Sampling methods and groundwater measurements: Part 1: Technical principles for execu

45、tion Part 2: Qualification criteria for enterprises and personnel Part 3: Conformity assessment of enterprises and personnel by third party EN ISO 22475-1:2006viii Introduction ISO 22475-1 specifies the technical principles for the execution of sampling and groundwater measurements for geotechnical

46、purposes. The quality of these services can be proven by: a) a declaration of conformity by a contractor (first party control); b) a declaration of conformity by a client (second party control); c) a declaration of conformity by a conformity assessment body (third party control). Every enterprise or

47、 individual may decide, if and how they will prove the fulfilment of the technically related criteria: by first, second or third party control because no part of ISO 22475 requires such a declaration. ISO/TS 22475-2 specifies the qualification criteria for enterprises and personnel that perform samp

48、ling and groundwater measurements according to ISO 22475-1. The conformity assessment by third party control can be made according to the technical principles for execution of sampling and groundwater measurements specified in ISO 22475-1, as indicated in ISO/TS 22475-2, and in the conformity assess

49、ment procedure given in ISO/TS 22475-3. EN ISO 22475-1:20061Geotechnical investigation and testing Sampling methods and groundwater measurements Part 1: Technical principles for execution 1 Scope This part of ISO 22475 deals with the technical principles of sampling of soil, rock and groundwater, and with groundwater measurements, in the context of geotechnica
