10、SISO39778:2002iiiIS-7793 O8:(2002)E vi I SO 2002 All irthgs ersedevr 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 technic
11、al 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 wi
12、th 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 3. The main task of technical committees is to prepare International Standards. Draft Inte
13、rnational 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 part of ISO
14、 3977 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3977-8 was prepared by Technical Committee ISO/TC 192, Gas turbines.

26、ional documentation, reports, material certificates, chemical analyses, physical or dimensional checks, build records, visual checks and/or results of documented inspections and tests including any other non- destructive evaluation (NDE) methods or techniques that may be employed. 3.2 test process b
27、y which it is demonstrated that assemblies, completed components or packages satisfy the physical, functional and operational requirements as specified by the packagers test schedules and procedures, or the purchasers specification 3.3 witnessed term meaning that a hold is applied to the production
28、schedule and that the inspection or test will be carried out with the purchaser or his representative in attendance 3.4 observed term meaning that the purchaser will be notified of the timing of the inspection or test NOTE However, the inspection or test should be performed as scheduled, and if the
29、purchaser or his representative is not present, the packager should proceed to the next step. 4 General principles The packager shall furnish the purchaser with inspection and testing plans. These define the actions required by the packager and his sub-suppliers to assure the integrity of the packag
30、e. These plans should include any specific requirements stated by the purchaser in his enquiry and any local or national regulations applicable to the package in either the country of origin or destination. The plan shall be agreed between the packager and purchaser, and any third-party inspector wh
31、o may be appointed by the purchaser, prior to commencement of manufacture. It is the purchasers responsibility to notify the packager of any applicable local and national regulations in the country of destination. Where inspection and testing have to be done on site, these shall be identified in the
32、 inspection and testing plans and agreed between the packager and purchaser. BSISO39778:20022ISO 3977-8:2002(E) I SO 2002 All irthgs ersedevr 3The packager and purchaser shall agree to the following: the extent of purchaser participation in the inspection and testing, including witnessed and observe
33、d test points; detail running test procedures and acceptance parameters and criteria; notification period for hold points and witnessed tests and observed tests; facilities and services to be provided by the purchaser. The packager shall keep at least the following data available for a minimum of 10
34、 years after the date of commissioning for examination by the purchaser or his representative upon request: certification of materials; purchase specifications for all items on bills of materials; test data to verify that the requirements of the specification have been met; results of documented mat
35、erial inspections, including fully identified records of all heat treatment and radiography processes; when specified, final-assembly maintenance and as-built clearances. In addition to the above requirements, the purchaser may specify the following: parts that shall be subjected to surface and subs
36、urface examination; the type of non-destructive evaluation to be applied. 5 Inspection 5.1 General Inspection activities are carried out throughout the entire manufacturing process and may cover materials, components, fabrications, sub-assemblies, auxillary packages, and finished gas turbine package
37、s. Where inspection activities involve pressure-containing parts, these shall not be painted until the specified inspection of the parts is completed. 5.2 Material inspection Non-destructive evaluation (NDE) procedures and acceptance criteria used in the manufacturing and assembly procedures for the
38、 gas generator, power turbine and all other items of equipment shall be in accordance with the agreed inspection and testing plans. BSISO39778:20023ISO 3977-8:2002(E) 4 I SO 2002 All irthgs ersedevr 5.3 Mechanical inspection During assembly and prior to functional/operational testing, components or
39、sub-assemblies (including cast-in passages of these components) and all piping and appurtenances shall be cleaned chemically or by another appropriate method to remove foreign materials, corrosion products and mill scale. Any portion of the oil system furnished shall meet the cleanliness requirement
40、s of ISO 4406. When specified, the purchaser may inspect the equipment and all piping and appurtenances furnished by or through the packager for cleanliness before heads are welded to vessels, openings in vessels or exchangers are closed, or piping is finally assembled. When specified, the hardness
41、of parts, welds and heat-affected zones shall be verified as being within the allowable values by testing of the parts, welds or zones. The method, extent, documentation and witnessing of the testing shall be mutually agreed upon by the purchaser and packager. 6 Testing 6.1 General This clause deals
42、 with the minimum recommended requirements for the physical testing of components, assemblies and the complete package prior to entry into commercial service. The purchaser and packager shall agree on the scope of testing. This may include a selection of optional tests specified by the purchaser as
43、described in 6.4. Figure 1 shows the desired sequence of mandatory and optional operation testing and may be used for guidance. All test reports shall be retained for periods consistent with the requirements of ISO 3977-2. 6.2 Hydrostatic test As a minimum, components defined by legislation or natio
44、nal standards as pressure vessels (excluding the casings of gas generator and power turbine) shall be tested hydrostatically according to legislation or national standards, but at least with liquid at a minimum of 1,5 times the maximum allowable working pressure but not less than 140 kPa differentia
45、l pressure. Other components and systems shall be tested in accordance with the purchasers requirements or statuatory or mandatory requirements applicable to the destination territory. The test liquid shall be at a higher temperature than the nil-ductility transition temperature of the material bein
46、g tested. If the part tested is to operate at a temperature at which the tensile strength of a material is below the tensile strength of that material at room temperature, the hydrostatic test pressure shall be multiplied by a factor obtained by dividing the allowable working stress for the material
47、 at room temperature by that at operating temperature. The data sheets shall list actual hydrostatic test pressures and temperatures. The chloride content of liquids used to test austenitic stainless-steel materials shall not exceed 50 parts per million. To prevent deposition of chlorides as a resul
48、t of evaporative drying, all residual liquid shall be removed from tested parts at the conclusion of the test. Tests shall be maintained for a sufficient period of time to permit complete examination of parts under pressure. The hydrostatic test shall be considered satisfactory when neither leaks no
49、r seepage through the casing or casing joint is observed for a minimum of 30 min. Large, heavy castings may require a longer testing period which is to be agreed upon by the purchaser and packager. Seepage past internal closures required for testing of segmented cases and operation of a test pump to maintain pressure are acceptable. BSISO39778:20024ISO 3977-
