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
