15、e three measurements.7. Dimensions7.1 Dimensions of rivets, unless otherwise specified, shallconform to those of one of the head types provided in ASMEB 18.1.2.8. Number of Tests and Retests8.1 Hardness:8.1.1 The requirements of this specification shall be met incontinuous mass production for stock,

16、 and the manufacturershall make sample inspections to ensure that the productconforms to the specified hardness requirements. Additionaltests of individual shipments of material are not ordinarilycontemplated. Individual heats of steel are not necessarilyidentified in the finished product.8.1.2 Addi

17、tional hardness tests of individual shipments ofrivets are not ordinarily required. When required, Supplemen-tary Requirement S1 shall be specified.8.2 Head Bursts and Duds:8.2.1 From each lot, the number of tests and the acceptance/rejection criteria for cracks (bursts) and duds shall be inaccordan

18、ce with Guide F 1470 using the sampling level char-acteristic specified for Surface Discontinuities.9. Specimen Preparation9.1 Rivets used for testing shall be heat treated in thefollowing manner prior to testing:9.1.1 Grade 1Normalize by air cooling from above thetransformation range.9.1.2 Grade 2A

19、nneal by heating to 1450F (790C),holding for 30 min at temperature and cooling in the furnace.9.1.3 Grade 3Normalizing test samples shall be at theoption of the manufacturer.9.2 If any test specimen shows defective preparation, it shallbe discarded and another specimen substituted.10. Visual Inspect

20、ion for Head Bursts and Duds10.1 The rivets shall be inspected for cracks (bursts) andduds. Sampling and inspection shall be in accordance with 8.2.Rivets having an opening at the periphery of the head widerthan 0.020 inch plus 0.05 times the rivet diameter shall beconsidered nonconforming (see Note

21、 1).NOTE 1Crack and burst are two names for the same thing. Eachdesignates an abrupt interruption of the periphery of a rivet head byseparation of the metal. Such interruptions do not adversely affectstructural strength, corrosion resistance, or other functional requirementsof the rivet, but are uns

22、ightly if they are large.11. Test Methods11.1 Hardness tests shall be conducted in accordance withTest Methods F 606.11.2 Chemical analyses shall be conducted in accordancewith Test Methods A 751.12. Inspection12.1 If the inspection described in 12.2 is required by thepurchaser, it shall be specifie

23、d in the inquiry and contract ororder.12.2 The purchasers representative shall have free entry toall parts of the manufacturers works or suppliers place ofbusiness that concern the manufacture or supply of the rivetsordered. The manufacturer or supplier shall afford the purchas-ers representative al

24、l reasonable facilities to satisfy him thatthe material is being furnished in accordance with this speci-fication. All tests and inspections required by the specificationthat are requested by the purchasers representative shall bemade before shipment, and shall be conducted as not toTABLE 1 Chemical
