16、nited Kingdom. EN ISO 15875-1:2003/A1:2007 (E) 3 Introduction In ISO 15875-2:2003, the base pipe is required to fulfil the dimensional 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 so
17、me countries it is common practice that the finished product be required to fulfil the dimensional requirements of the standard. This situation creates a problem throughout the world due to different requirements in different countries. It illustrates the need to have a common procedure on the marke
18、t for dealing with this matter. ISO 15875-2:2003/Amd. 1:2007 was developed to clarify the requirements on dimensions and tolerances for 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 b
19、arrier layer and supplements ISO 15875-2:2003/Amd. 1:2007. EN ISO 15875-1:2003/A1:2007 (E) 4 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 gas
20、es and the transmission of 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 cons
21、idered as multilayer pipes (see Bibliographic references 5 to 8), with the outside layer then being the first of multiple layers rather than having only a barrier function.
