9、.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 committees. Each membe
10、r 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 the International Elec
11、trotechnical 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 International Standards adopt
12、ed 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 the subject of paten
13、t rights. ISO shall not be held responsible for identifying any or all such patent rights. Amendment 1 to ISO 15874-1:2003 was prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of f
14、luids, Subcommittee SC 2, Plastics pipes and fittings for water supplies, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

16、 barrier is an “add on” giving to the finished product a wall thickness and outside diameter greater than stated in that part of ISO 15874. In some countries it is common practice that the finished product be required to fulfil the dimensional requirements of the standard. This situation creates a p
17、roblem 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 15874-2:2003/Amd. 1:2007 was developed to clarify the requirements on dimensions and tolerances for barrier pipes and c
18、reate a common procedure for designing and testing those pipes. Amendment 1 to ISO 15874-1:2003 clarifies the definition of the term pipes with barrier layer and supplements ISO 15874-2:2003/Amd. 1:2007.

20、(PP) Part 1: General AMENDMENT 1 Page 4, 3.1.3.5 Delete definition 3.1.3.5 and replace it with definition 3.1.4, as follows: 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 light thro
21、ugh 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 (see Bibli
22、ographic references 7 to 10), with the outside layer then being the first of multiple layers rather than having only a barrier function.
