19、steelshaving a heat analysis conforming to the requirements in Table1.5.2 Product Analysis:5.2.1 Analyses of finished eyebolts may be made by thepurchaser or may be requested to be made by the manufacturer.The composition thus determined shall conform to the productanalysis requirements specified in

20、 Table 1.5.3 Chemical analyses shall be performed in accordancewith A751 Test Methods, Practices, and Terminology forChemical Analysis of Steel Products.6. Mechanical Properties6.1 Proof LoadThe lifting eyes shall withstand the proofload specified in Table 2.6.1.1 The proof load is defined as the lo

21、ad that can beapplied to the eyebolt without causing permanent deformation.Prick punch marks shall be applied at opposite ends of thediameter across the eye. The proof load shall be applied byscrewing the eyebolt to the full thread engagement into a blocksecured in one jaw of the testing machine and

22、 held to the otherjaw by means of a mandrel passing through the eye. The roundmandrel shall have a diameter equal to one half of the insidediameter of the eye. The proof load shall be applied at amaximum cross head speed of 0.12 in. per minute, held for 10s. and then released. Permanent deformation

23、of the eyeboltexceeding 0.01 in. between the prick punch marks constitutesa failure.6.2 Breaking StrengthThe lifting eyes shall conform to thebreaking strength specified in Table 2.6.2.1 The breaking strength shall be determined by screw-ing the eyebolt to the full thread engagement into a blocksecu

For use at temperatures below 32 F, refer to alloy steel eyebolts in accordance with SpecificationF541.SUMMARY OF CHANGESCommittee F16 has identified

48、 the location of selected changes to this standard since the last issue (A48912)that may impact the use of this standard.(1) This standard has been completely re-written. Changes arenot identified due to the extent of the changes.(2) Load values in Table 2 were revised based on consistentrounding.(3

49、) Thread size in Table 2 corrected for typographical error.(4) Grain size testing has been deleted since current manufac-turing process make this unnecessary. The previous require-ment for a minimum grain size of 5 was not stringent.(5) Impact testing has been deleted since usage of carbon steeleyebolts should be restricted to greater than 32 F making suchtesting unnecessary.(6) Product marking (A489) was added to facilitate identifica-tion and to provide comparison with Specification F541produ
