26、 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 represente
27、d 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 draf
28、ted 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 Sta
29、ndard 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 10414-1 was prepare
30、d by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 3, Drilling and completion fluids, and well cements. This second edition cancels and replaces the first edition (ISO 10414-1:2001), to which Annex
31、es I, J and K have been added and other minor changes made to the sentence structure, grammar and other non-technical editing. ISO 10414 consists of the following parts, under the general title Petroleum and natural gas industries Field testing of drilling fluids: Part 1: Water-based fluids Part 2:
32、Oil-based fluids vi Introduction This part of ISO 10414 is based on API RP 13B-1, third edition, December 20032 and ISO 10414 (all parts)6. Annexes A to H and K of this part of ISO 10414 are for information only. Annexes I and J are normative. In this part of ISO 10414, where practical, U.S. Customa

34、r is expected to have proper knowledge and to have received training in the use and disposal of these chemicals. The user is responsible for compliance with all applicable local, regional and national requirements for worker and local health, safety and environmental liability. 1 Scope This part of
35、ISO 10414 provides standard procedures for determining the following characteristics of water-based drilling fluids: a) drilling fluid density (mud weight); b) viscosity and gel strength; c) filtration; d) water, oil and solids contents; e) sand content; f) methylene blue capacity; g) pH; h) alkalin
