Test Methods7.1 All fluid conditioner fittings shall be pressure tested byone of the following methods:7.1.1 Conduct a hydrostatic test at 112 times the 100F(37C) rated MAWP of the fluid conditioner fitting. Perfo
39、rmthe test with water or other liquid having a maximum viscosityof 40 SSU at 125F (52C) with a maximum pressure testtemperature of 125F (52C). The minimum duration of thetest shall be 15 s for fluid conditioner fittings less than NPS 2(50 mm), 1 min for fluid conditioner fittings NPS 212 (63 mm)thro
40、ugh 8 (203 mm), and 3 min for larger sizes. The purpose ofthis test is to detect leaks and structural imperfections. Novisible leakage is permitted.7.1.2 Class II fluid conditioner fittings of NPS 2 (50 mm)and smaller with other than flanged connections may, at theoption of the manufacturer, be air
41、tested to the lesser of 1.2times the MAWP or 80 psig (0.55 MPa). The minimumduration of the test shall be 15 s. Visually detectable leakage isnot acceptable.7.1.2.1 Manufacturers exercising this option shall also cer-tify that a prototype from each production lot of the same sizefluid conditioner fi
42、tting was subjected to a hydrostatic test inaccordance with 7.1.1.7.2 Test a prototype of a fluid conditioner fitting design thatrequires a fire test in accordance with 5.2 as follows:7.2.1 Position the fluid conditioner fitting 9 in. (230 mm)above the top edge of an open pan of heptane large enough
43、 toengulf the fluid conditioner fitting completely in the fire. Thepan shall conform to the following minimum dimensions:7.2.1.1 Depth,112 in. (38 mm).7.2.1.2 Width, twice the width of the fluid conditioner fittingbut no less than 812 in. (220 mm).7.2.1.3 Length, twice the length of the fluid condit
44、ionerfitting but no less than 14 in. (360 mm).7.2.2 Add to the pan sufficient heptane to provide for a212-min burn.7.2.3 Mount thermocouples so as to sense the flame tem-perature in the same plane and elevation as the fluid condi-tioner fitting assembly. Pressurize with water the fluid condi-tioner
45、fitting to its MAWP during the burning portion of thetest. Following ignition of the heptane, begin timing andmonitor the temperature. The temperature shall reach a mini-mum of 1200F (649C) but shall not exceed 1350F (732C).If 1200F (649C) is not reached, repeat the test using a newspecimen. If 1350
46、F (732C) is exceeded, discard the resultsand repeat the test.7.2.4 At the end of the 212-min of fire exposure, extinguishthe flame, relieve the pressure, and allow the water to flowthrough the assembly. With free flow established, pressurizethe fluid conditioner fitting to its MAWP and hold for 30 s
47、.Failure to establish a free flow, or any fluid leakage during fireexposure or the subsequent pressure test, shall constitutefailure.7.2.5 Mount in their normally installed position those fluidconditioner fittings that require external protective devicesinstalled to pass the above fire test. Test in
48、 each position thosefluid conditioner fittings that can be mounted in more than oneposition. A different fluid conditioner fitting may be used foreach test. If it is possible for this protection to be separatedfrom the fluid conditioner fitting body by purchasers or users,mark the body to indicate t
49、hat this protection is required (see9.2).7.2.6 Test only the smallest and largest sizes of a particularfluid conditioner fitting design to certify the design as havingpassed the above fire test.NOTE 1Manufacturers are cautioned that the application of this testcan be hazardous. It is recommended that it be performed by a qualifiedlaboratory familiar with the conduct of this type test.7.3 Inspect all welds as follows:7.3.1 Visually examine all welds in accordance with ANSIB31.1.7.3.2 Welded inlet and outlet connections of Class I fluidcond
