Materials and Manufacture6.1 MaterialsThe materials for all wetted parts shall beselected for long-term compatibility with the process mediumand ambient conditions.6.2 Material Inspe
16、ctionThe manufacturer shall be respon-sible for ensuring that materials used are manufactured, exam-ined, and tested in accordance with the specifications andstandards as applicable.6.3 Gaskets and O-RingsGaskets and O-rings shall befabricated of materials suitable to the operating pressure,temperat
17、ure, and process medium for each application.7. Physical Properties7.1 ConnectionsSight indicators are usually installed us-ing standard pipe fittings or flanges. Pipe fittings and materialshould match that of the existing pipe for each installation.Type and size of fittings shall be specified in th
18、e acquisitionrequirements. Welding or brazing shall be performed in accor-dance with industry standards.7.2 Flanged ConnectionsWhere sight indicators are in-stalled using flanges, flanges shall be in accordance with ANSIB16.5. Standard flange sizes include 1.27 cm (12 in.), 1.9 cm(34 in.), 2.54 cm (
19、1 in.), 3.8 cm (1-12 in.), and 5.08 cm (2 in.).Standard flange pressure ratings include 1.034 MPa (150 psi),2.07 MPa (300 psi), and 4.14 MPa (600 psi). Other flangerequirements shall be specified in the acquisition requirements.7.3 Vent and Drain ConnectionsWhere required, vent anddrain connections
20、are usually plugged,12-or34-in. NPT orwith NPT valves. Other vent and drain connections shall bespecified in the acquisition requirements.8. Performance Requirements8.1 Performance ConsiderationsIn many applications,certain performance characteristics are deemed critical to theintended or desired fu
21、nction of a sight liquid level indicator.The following are prime examples:(1) Accuracy,FIG. 1 Indicator Design TypesF 2045 00 (2006)2(2) Shock and vibration classifications, and(3) Operating pressure and temperature ranges.9. Workmanship, Finish, and Appearance9.1 Finish and AppearanceAny special su
22、rface finish andappearance requirements shall be specified in the acquisitionrequirements.9.2 Sight Glass CleaningAny special cleaning require-ments shall be specified in the acquisition requirements.10. Inspection10.1 Classification of InspectionsThe inspection require-ments specified herein are cl
23、assified as follows:(1) Qualification testing and(2) Quality conformance testing.10.2 Qualification TestingQualification test requirementsshall be specified where applicable. Qualification test methodsshould be identified for each design and performance charac-teristic specified. Test report documen
24、tation requirementsshould also be specified.10.3 Quality Conformance TestingQuality conformancetesting is accomplished when qualification testing was satisfiedby a previous acquisition or product has demonstrated reliabil-ity in similar applications. Quality conformance testing isusually less intens
25、ive than qualification, often verifying thatsamples of a production lot meet a few critical performancerequirements.11. Number of Tests and Retests11.1 Test SpecimenThe number of test specimens to besubjected to qualification testing shall depend on the design. Ifeach range is covered by a separate
26、and distinct design, a testspecimen for each range will require testing. In instances inwhich a singular design series may cover multiple ranges andtypes, only three test specimens need be tested provided thephysical similarities are approved by the buyer. In no case,however, shall less than three u
27、nits, one unit each representinglow, medium, and high ranges, be tested, regardless of designsimilarity.12. Test Methods12.1 TestsAll tests shall be performed in accordance withASTM, ASME, or industry standards as specified.12.2 Test DataAll test data shall remain on file at themanufacturers facilit
28、y for review by the buyer upon request. Itis recommended that test data be retained in the manufacturersfiles for at least three years or a period of time acceptable to thebuyer and manufacturer.13. Quality Assurance Provisions13.1 WarrantyUnless otherwise specified, the manufac-turer is responsible
29、 for the following:(1) All materials used to produce a unit and(2) Manufacturer will warrant his product to be free fromdefect of workmanship to produce the unit.14.
