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 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 the 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 International 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 the subject of patent rights.ISO shall not be held responsible for identifying any or all such patent rights.ISO 14692-2 was prepared by Technical Committee ISO/TC 67,Materials,equipment and offshore structures for petroleum,petrochemical and natural gas industries,Subcommittee SC 6,Processing equipment and systems.This second/third/.edition cancels and replaces the first/second/.edition(),clause(s)/subclause(s)/table(s)/figure(s)/annex(es)of which has/have been technically revised.ISO 14692 consists of the following parts,under the general title Petroleum and natural gas industries Glass-reinforced plastics(GRP)piping:Part 1:Vocabulary,symbols,applications and materials Part 2:Qualification and manufacture Part 3:System design Part 4:Fabrication,installation,inspection and maintenance ISO/WD 14692-2 ISO 2013 All rights reserved vii Introduction The objective of this part of ISO 14692 is to enable the purchase of GRP components with known and consistent properties from any source.Main users of the document will be the principal and the manufacturer,certifying authorities and government agencies.The qualification programme and the quality programme are the most significant clauses in Part 2.WORKING DRAFT ISO/WD 14692-2 ISO 2013 All rights reserved 1 Petroleum and natural gas industries Glass-reinforced plastics(GRP)piping Part 2:Qualification and manufacture 1 Scope This part of ISO 14692 gives requirements for the qualification and manufacture of GRP piping and fittings in order to enable the purchase of GRP components with known and consistent properties from any source.It is applicable to qualification procedures,preferred dimensions,quality programmes,component marking and documentation.This part of ISO 14692 is intended to be read in conjunction with ISO 14692-1.2 Terms,definitions,symbols and abbreviated terms For the purposes of this document,the terms,definitions,symbols and abbreviated terms given in ISO 14692-1 apply.3 Manufacturers declarations Prior to the start of the qualification programme,the manufacturer shall declare 1)gxx,2)MPRxx,3)the long term envelope data points,4)the threshold envelope data points,5)dimensional data and 6)baseline values for degree of cure,barcol hardness(GRUP and GRVE only)and glass content,where applicable.The data shall be based on a standard design life of 20 years.ISO/WD 14692-2 2 ISO 2013 All rights reserved Figure 1 Procedure for declaring manufacturers data ISO/WD 14692-2 ISO 2013 All rights reserved 3 Figure 1(continued)Procedure for declaring manufacturers data 3.1 Long term regression testing The manufacturer shall provide at least one full regression curve(as per ASTM D2992 as modified in this clause and in Clause 4.1.The regression curve shall be at 65 C or higher for GRE and 21 C or higher for GRUP or GRVE.NOTE The one full regression curve does not have to be at or above the design temperature of the project.For example,the Enquiry sheet specifies a design temperature of 93 C and the manufacturer has a full regression curve at 85 C for GRE-Aliphatic Amine.Since the resin matrix is GRE and the temperature of the full regression curve is above 65 C,the data is acceptable.The manufacturers gradient from the full regression curve can be compared to the values in Table B.1 and a gradient can be selected per the process in Annex B.On the other hand,validation of the long term envelope via survial tests would have to be performed at the design temperature of the project.The manufacturer shall conduct the long term regression on either a plain pipe or a pipe+joint,in a single pipe size,the size to be determined by the manufacturer.NOTE For economical and practical reasons,long term regression testing is typically conducted on small diameters.The recomended minimum pipe size is DN50.Data seems to be more consistent as the size increases(i.e.DN100 test results seem to be more consistent than DN50 test results).The Dr,min/tr,min ratio of the pipe size shall be within the range of published Dr,min/tr,min ratios that are to be qualified.ISO/WD 14692-2 4 ISO 2013 All rights reserved NOTE Ideally,the Dr,min/tr,min ratio of the pipe size should be close to the average Dr,min/tr,min ratio of all of the pipe sizes to be qualified.It is not desirable to have the Dr,min/tr,min ratio of the pipe size at either extreme.The test fluid shall be potable water.NOTE For testing completed prior to the publication of this standard,the test fluid may be salt water.In this case,the salt content must be specified and it must not be greater than 35 g/L.The intention of this requirement is to allow validation of existing test data completed before the publication of this document,but to require potable water for future testing.Potable water is a more aggressive test media than salt water.Test data using mineral oil should be rejected since mineral oil is not a degrading agent to the bond between the glass fibres and the resin matrix.All tests shall be conducted with unrestrained(i.e.free)ends.3.2 Gradient,Gxx The manufacturer shall declare gradient,Gxx,in accordance with Annex B.3.3 MPRxx MPRxx is the maximum pressure rating at sustained conditions for a 20 year design at the temperature of xx C.MPRxx shall be the maximum catalogue value published by the manufacturer.MPRxx shall be defined at 65 C for GRE(MPR65)and 21 oC for GRUP and GRVE(MPR21).For design temperatures in excess of 65 C for GRE and 21 oC for GRUP and GRVE,the manufacturer shall also publish MPRxx at the design temperature or higher.The following shall be noted:a)Default temperatures are 65 C(MPR65)for GRE and 21 oC(MPR21)for GRVE and GRUP.For clarity,MPR shall always be published with a temperature subscript(e.g.MPR65 or MPR21,not MPR).b)The d
