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.

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

The samples shall be representative of the products proposed to be furnished to this specification. When a manufacturer is in continu

43、ous production of the fittings from one contract to another or has demonstrated within the past 2 years the capability to meet the requirements of this specification, inspection of additional first article samples for a new contract may be waived at the discretion of the acquiring activity (see 6.3)

44、. Approval of the first article samples or the waiving of first article inspection does not preclude the requirements for performing conformance inspection. First article samples shall be furnished to the Government as directed by the contracting officer (see 6.3). 4.4.2 Inspection routine. The samp

45、le(s) shall be subjected to the first article inspections specified in table III and in the specified sequence. 4.4.3 Failures.
