ISO 14692-2:2002(E) © ISO 2002 — All rights reserved v 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 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.

These shall be qualified in accordance with the qualification programme given in Clause 6. Changes in materials of construction require components to be re-qualified in accordance with 6.2.8. 5.2 Fibre The principal reinforcement material of the component wall shall be glass fibre, e.g. continuous and/or woven rovings. The application of this part of ISO 14692 to pipes manufactured with other reinforcement fibres shall be done with caution and in agreement with the principal. Other types of fibre reinforcement, such as carbon or aramid fibre, may be used to provide local strengthening within fittings. Such components shall be qualified by survival tests according to 6.2.3.2.2. Use of low electrical resistivity fibres, e.g. carbon, for non-structural purposes to provide electrical conductivity shall be permitted. NOTE 1 Glass fibre is the preferred reinforcement material because there is little information available about the long-term pressure retention, impact and fire performance of pipes manufactured from other reinforcement materials such as carbon or aramid fibre. NOTE 2 If significant quantities of carbon are present, either as fibre or filler, it may be necessary to electrically insulate the surface of the component where it could come into contact with adjacent metal components with glass-fibre-reinforced material because of the risk of galvanic corrosion. 5.3 Resin The manufacture of components shall be limited to thermosetting resins. Typical resins are epoxy, polyester, vinyl ester and phenolic. NOTE 1 See ISO 14692-1:2002, Clause 6. Caution shall be applied to the use of fillers within the resin, since these can result in differing properties compared to the base resin, which will affect the long-term performance of the pipe. The resin shall have a glass transition temperature, Tg, that is greater than or equal to 95 °C. The Tg shall be 30 °C above the standard qualification temperature, which is 65 °C. SIST EN ISO 14692-2:2004
ISO 14692-2:2002(E) 4 © ISO 2002 — All rights reserved The qualification requirements given in this part of ISO 14692 are not applicable to pipe systems that incorporate internal thermoplastic or elastomeric liners. NOTE 2 The use of a thermoplastic liner will result in change of the failure mode for pressure retention. Such liners also have an influence on the fire endurance and electrostatic properties of the pipe. Thermosetting resins that incorporate fibres or other filler material may be used as a liner on the inside of the pipe to provide enhanced performance, e.g. wear resistance and electrical conductivity. The liner material shall be compatible with the service conditions. External coatings may be used to provide thermal insulation, fire resistance or electrical conductivity. However, consideration shall be given to identifying how such coatings affect the ability to detect possible leakage paths through the wall of the component during hydrotesting, or the effect that the additional mass of external coating may have on the overall stress analysis. 5.4 Joints 5.4.1 General The joints are often the greatest area of concern with regard to the overall integrity of the piping system. The principal types of joint are: a) adhesive/resin for bonded/laminated joints; and b) mechanical joints. The requirements given in 5.4.2 and 5.4.3 apply. The manufacturer shall apply an equivalent level of qualification requirements to new jointing systems that may be developed in the future. 5.4.2 Adhesive/resin for bonded/laminated joints The adhesive to be used in the factory or field shall be the same as that used in the qualification tests. The adhesive/laminating resin shall have properties suitable for field assembly and shall fulfil the following requirements. a) The adhesive or laminating resin shall have a suitable viscosity for application at site temperature and humidity conditions. b) The degree of cure shall be determined in accordance with the procedures given in 6.8.2. The following shall apply, depending on the method used to determine degree of cure: =the glass transition temperature, Tg, of the cured adhesive or resin shall not be less than 95 % of the minimum value quoted by the manufacturer for the adhesive or resin system, as measured in accordance with 6.8.2.2; =the styrene content shall be no more than 2 % (mass fraction) of resin content, as measured in accordance with 6.8.2.3; =the Barcol hardness shall be at least 90 % of the minimum value quoted by the supplier and agreed with the principal, as measured in accordance with 6.8.2.4. If an alternative method has been used to determine the baseline for degree of cure, then the acceptance criteria for quality control shall be in agreement with the principal. c) The supplier shall record the test procedures used to determine the adhesive/resin properties. SIST EN ISO 14692-2:2004
ISO 14692-2:2002(E) © ISO 2002 — All rights reserved 5 5.4.3 Mechanical joints The manufacturer shall ensure that the materials of construction of ancillaries such as O-rings, lubricants, gaskets, mastic and locking strips are suitable for the intended service conditions. 5.5 Wall thickness limitations The structural calculations given in this part of ISO 14692 are only valid for thickness-to-diameter ratios that are in accordance with Equation (1). r0,1tDu (1) where tr is the average reinforced thickness of the wall, in millimetres, i.e. excluding liner and added thickness for fire protection; D is the mean diameter, in millimetres, of the structural portion of the wall. In order to provide sufficient robustness during handling and installation, the minimum total wall thickness, tmin, of all components shall be defined as: For Di W 100 mm: tmin W 3 mm (2) For Di < 100 mm: minitD W 0,025 mm (3) where Di is the internal diameter of the reinforced wall of the component, in millimetres. For more onerous applications, for example offshore, consideration should be given to increasing the minimum wall thickness to 5 mm. The minimum wall thickness of the pipe at the joint, i.e. at the location of the O-ring or locking-strip groove, shall be at least the minimum thickness used for the qualified pipe body. Depending on location, the system design pressure and other design factors can significantly increase the required wall thickness. 6 Qualification programme 6.1 General The qualification programme consists of standard methods for quantifying component performance with respect to static internal pressure, elevated temperature, chemical resistance, electrostatic and fire performance properties, with optional methods for quantifying potable water, impact, low temperature and limited cyclic pressure performance. The manufacturer is required to determine a qualified pressure pq, see 6.2.1.1, which is related to the manufacturer's nominal pressure rating pNPR by the expression given in Equation (4). pNPR = f2 ⋅ f3,man ⋅ pq (4) where f2
is a load factor (or safety factor); f3,man is a factor to account for the limited axial load capability of GRP. SIST EN ISO 14692-2:2004
ISO 14692-2:2002(E) 6 © ISO 2002 — All rights reserved NOTE 1 See 7.2 and 7.10 of ISO 14692-3:2002 for further explanation. The manufacturer shall provide the values of f2 and f3,man used to develop a purchase quotation. Values of f2 = 0,67 and f3,man = 0,85 are recommended as a default. NOTE 2 f3,man is based on f3 which is not a fixed parameter and is strongly dependent on the application and qualified pressure of the material. Components that have been subjected to qualification testing shall not be used as part of a GRP pipeline or piping system. The qualification programme also includes testing of components in order to provide data for a) quality control, b) system design. NOTE 3 For flat regression curves (see 6.2.1.1) with a regression gradient of less than 0,03 it may not be possible, due to statistical uncertainty in extrapolation, to derive pq. 6.2 Qualification pressure and temperature 6.2.1 General 6.2.1.1 Pressure terminology and service conditions Manufacturers shall assign all components a qualified pressure, pq, expressed in megapascals2), as determined according to 6.2.2.
