9、ISO 15875-1:2003/Amd.1:2007(E) ISO 2007 All rights reserved iii Foreword 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 co
10、mmittees. 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 closely with th
11、e 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 Internati
12、onal 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 document may be
13、the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Amendment 1 to ISO 15875-1:2003 was prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 138, Plastics pipes, fittings and valves fo

16、requirements and the barrier is an “add on” giving to the finished product a wall thickness and outside diameter greater than stated in that part of ISO 15875. In some countries it is common practice that the finished product be required to fulfil the dimensional requirements of the standard. This s
17、ituation creates a problem throughout the world due to different requirements in different countries. It illustrates the need to have a common procedure on the market for dealing with this matter. ISO 15875-2:2003/Amd. 1:2007 was developed to clarify the requirements on dimensions and tolerances for
18、 barrier pipes and create a common procedure for designing and testing those pipes. Amendment 1 to ISO 15875-1:2003 clarifies the definition of the term pipes with barrier layer and supplements ISO 15875-2:2003/Amd. 1:2007.

20、tions Crosslinked polyethylene (PE-X) Part 1: General AMENDMENT 1 Page 4, 3.1.4 Replace the definition of the term with the following: 3.1.4 pipes with barrier layer plastics pipes provided with a thin barrier layer (e.g. to prevent or greatly diminish the diffusion of gases and the transmission of
21、light through the pipe wall) and where the design stress requirements are totally met by the base polymer NOTE Such pipes typically have an outside (barrier) layer of maximum 0,4 mm thickness, including any adhesive. Pipes with an outside layer greater than 0,4 mm are considered as multilayer pipes
22、(see Bibliographic references 5 to 8), with the outside layer then being the first of multiple layers rather than having only a barrier function.
