On straight fittings where the fluid passage is drilled from each end, the offset between the drilled holes at the meeting po
27、int of the drills shall not exceed 0.015 inch (see 4.7.2). 3.7.3 Angle fittings. On angle fittings, the cross-sectional area at the junction of the fluid passages shall not be smaller than the cross-sectional area of the smaller passage (see 4.7.3). 3.7.4 Wall thickness. Except as otherwise specifie
28、d on the applicable AN or MS standard, the wall thickness at any point on the fitting shall be not less than the thickness established by the dimensions and tolerances for the inside and outside diameters and eccentricities specified in the AN or MS standard (see 4.7.4). 3.7.5 Leakage test.

31、st specified in 4.7.8. 3.8 Identification of product. All fittings shall be marked in accordance with the following instructions. The marking shall be applied in a location not detrimental to the fitting and shall not be detrimental to the corrosion protection of the fitting. 3.8.1 AN or MS symbols
32、and trademarks. Unless otherwise specified, all fittings shall be marked with the letters AN or MS and the manufacturers name or trademark. The marking shall be permanent, preferably embossed letters or impression stamping. However, ink stamping may be used. The letters AN or MS shall be separated a
33、nd distinct from the manufacturers name or trademark. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-6001B 5 3.8.2 Identifying number or letter. Wherever practicable, each fitting shall also be identified by the complete AN or MS standard nu
34、mber as shown by the AN or MS standard. The size and material code letter is not to be included with the standard number. The identifying number shall be added to the part by embossing, impressing stamping, ink stamping, or printed on a paper collar supplied with the fitting. The preferable marking
35、shall be in the order mentioned. The identifying number shall not be placed on the union nut specified in AN805. Also the fittings in sizes -6 and under need not be individually marked but shall be packaged in units, with the package carrying the identifying number. 3.9 Workmanship. Fittings shall b
36、e free from burrs and longitudinal and spiral tool marks. All sealing surfaces shall be smooth except that annular tool marks up to 100 microinches rms maximum will be acceptable. Workmanship shall conform to the best commercial practice to produce fittings free from all defects which will affect pr
37、oper functioning in service. TABLE II. Performance requirements.
