16、O 15875-2:2003/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 some countries it is c
17、ommon 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 market for dealing with t
18、his matter. Amendment 1 to ISO 15875-2:2003 has been developed to clarify the requirements on dimensions and tolerances for barrier pipes and create a common procedure for designing and testing those pipes. EN ISO 15875-2:2003/A1:2007 (E) 4 Page 4, 6.1.3 Replace the subclause with the following: 6.1
19、.3 The values of outside diameter and/or wall thickness apply to the crosslinked polyethylene pipe and are exclusive of additional outside layers. For pipes with barrier layer1), the values of outside diameter and wall thickness may apply to the finished product, including the barrier layer, provide
20、d that the thickness of the outside barrier layer, including any adhesive layer, is 0,4 mm and the design calculation using the values of outside diameter and wall thickness of the base pipe (PE-X) meet the Scalc,maxvalues according to Table 1. The manufacturer shall state the dimensions and toleran
21、ces of the base pipe in his documentation when different from Tables 2 to 6 of this part of ISO 15875. NOTE For certification purposes, when a plastic barrier layer is embedded in the PE-X pipe wall, this construction is covered by this part of ISO 15875 until such time as the International Standard
