17、icable.6.3 Gaskets and O-RingsGaskets and O-rings shall befabricated of materials suitable to the operating pressure,temperature, and process medium for each application.7. Physical Properties7.1 ConnectionsSight indicators are usually installed us-ing standard pipe fittings or flanges. Pipe fitting
18、s and materialshould match that of the existing pipe for each installation.Type and size of fittings shall be specified in the acquisitionrequirements. Welding or brazing shall be performed in accor-dance with industry standards.7.2 Flanged ConnectionsWhere sight indicators are in-stalled using flan

Performance Requirements8.1 Performance ConsiderationsIn many applications,certain performance characteristics are deemed critical to theintended or desired function of a sight liquid level indicator.The following are prime examples:(1) Accuracy,(2) Shock and vibration classifications, an
22、d(3) Operating pressure and temperature ranges.9. Workmanship, Finish, and Appearance9.1 Finish and AppearanceAny special surface finish andappearance requirements shall be specified in the acquisitionrequirements.9.2 Sight Glass CleaningAny special cleaning require-ments shall be specified in the a
23、cquisition requirements.10. Inspection10.1 Classification of InspectionsThe inspection require-ments specified herein are classified as follows:(1) Qualification testing and(2) Quality conformance testing.10.2 Qualification TestingQualification test requirementsshall be specified where applicable. Q
24、ualification test methodsshould be identified for each design and performance charac-teristic specified. Test report documentation requirementsshould also be specified.10.3 Quality Conformance TestingQuality conformancetesting is accomplished when qualification testing was satisfiedby a previous acq
25、uisition or product has demonstrated reliabil-ity in similar applications. Quality conformance testing isusually less intensive than qualification, often verifying thatsamples of a production lot meet a few critical performancerequirements.11. Number of Tests and Retests11.1 Test SpecimenThe number
26、of test specimens to besubjected to qualification testing shall depend on the design. Ifeach range is covered by a separate 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 speci
27、mens need be tested provided thephysical similarities are approved by the buyer. In no case,however, shall less than three units, one unit each representinglow, medium, and high ranges, be tested, regardless of designsimilarity.12. Test Methods12.1 TestsAll tests shall be performed in accordance wit
28、hASTM, ASME, or industry standards as specified.12.2 Test DataAll test data shall remain on file at themanufacturers facility 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 thebuye
29、r and manufacturer.13. Quality Assurance Provisions13.1 WarrantyUnless otherwise specified, the manufac-turer is responsible 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.
