Nothing in this document, however, supersedes applicable laws and regulations
11、unless a specific exemption has been obtained. 3. REQUIREMENTS 3.1 Material. Terminal material shall conform to one of the following SAE steel grades: 4037, 4130, 4140, 4340, 6150, 8630 or 8740. 3.2 Design. 3.2.1 Form and Dimensions. Forms and dimensions shall be specified on the AN665. 3.2.2 Tolera
12、nces. The tapped hole, counter drilled hole and slot shall be central and parallel within the tolerances specified in AN665. 3.3 Protective Coating of Terminals. Protective coating of terminals shall be zinc plated in accordance with ASTM B633. 3.4 Tensile Strength. The tensile strength shall be no
13、less than 115 percent of the rated strength listed on AN665 under the heading “Rated Tie Rod Strength Min (lb)”. 3.5 Hardness. The hardness limits shall be within the range C26 and C31 Rockwell. 3.6 Resistance to Bend. Each prong of the fork of the terminal shall withstand a bend through the followi
14、ng range without cracking or indication of failure: Terminal Size Angle of Bend Degrees 6-4- to 1/2-20 inclusive 20 9/16 - 18 and 5/8 18 15 3.7 Workmanship. Shall be in accordance with high grade aircraft manufacturing practice for this type of work. Provided by IHSNot for ResaleNo reproduction or n

Test specimens shall be selected from the general run of production. Sufficient terminals to insure uniformity and
16、 conformance to the specified requirements shall be selected at random from each lot for test. 4.2.1 Lot. A lot shall consist of all terminals of the same type and size produced from the-same lot of steel and submitted for inspection at the same time. 4.3 Tests. 4.3.1 Examination of Product. Termina
17、ls shall be carefully inspected for conformance with the requirements of this specification with respect to workmanship, form, dimensions, threads, and marking. 4.3.2 Corrosion Resistance.- The terminals selected for inspection shall be tested for corrosion resistance in accordance with the Salt Spr
18、ay tests specified in Specification ASTM G47 and ASTM G69. 4.3.3 Tensile Strength. Tensile load shall be gripped through a stay bolt screwed into the threaded end of the sample terminal, and an eyebolt or plate held by a clevis pin in the fork end of the terminal. 4.3.4 Resistance to Bending. Termin
19、als shall be gripped by the cylindrical shank and the prongs of the fork bent through the specified angle by means of a gradually applied pressure. 4.4 Rejection and Retest. 4.4.1 Failure Under Tensile Strength or Resistance to Bend Test. If a test specimen fails to meet either of the tests, one mor
20、e terminal shall be selected from the same lot. If this terminal fails to meet either or both of the required tests, the entire lot which it represents shall be rejected. The manufacturer may be allowed to reheat treat the whole lot of terminals before final tests are made. However, where failure is
21、 definitely ascribed to faulty material, no retest shall be permitted. 4.4.2 Failure Under Corrosion Resistance Tests. If any sample terminal fails to conform to the corrosion resistance requirements, the Inspector shall select from the lot, additional samples, three times as many as the number whic
22、h failed. The failure of any of these additional samples shall be cause for rejection of the entire lot represented. The Inspector may, at his discretion, permit the manufacturer to strip and replate lots of tie rod terminals rejected due to failure to conform to corrosion-resistance requirements. I
23、n this case, however, the Inspector shall select samples, and witness corrosion-resistance tests of twice as many terminals from the replated lot as were originally selected as samples from the lot.

24、-DTL-5683B 45. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging acti
25、vity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activities within the Military Service or Defense Agency, or within the military services system commands. Packaging data retrieval is available from the managing Military Depart
26、ments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity. 6. Notes. (This section contains Information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. The terminals covered by this specif
27、ication are intended for use in the construction of aircraft and aircraft accessories. 6.2 Acquisition requirements. Acquisition documents should specify the following: a. Title, number, and date of this specification. b. AN part number (see AN665). c. Packaging requirements (see 5.1). 6.3 Subject t
