SPECIFICATIONS FOR BOILER RIVET STEEL. 505 



VI. MARKING. 



16. Marking. The name or brand of the manufacturer and the melt number shall be legibly 

 st.iui|)-il in rullrd on all finished material, except that rivet and lattice bars and other small sections 

 sh.ill, \\hen loaded fur shipment, I"- properly separated and marked for identification. The 

 idem ilicati MI marks shall l>c legibly stamped on the end of each pin and roller. The melt number 

 shall IK- legibly marked, by stamping if practicable, on each test specimen. 



VII. INSPECTION. 



17. Inspection. The inspector representing the purchaser shall have free entry, at all times 

 while work uii the contract of the purchaser is being performed, to all parts of the manufacturer's 

 works which run era the manufacture of the material ordered. The manufacturer shall afford 

 t he inspector, free of cost, all reasonable facilities to satisfy him that the material is being furnished 

 in accordance with these specifications. All tests (except check analyses) and inspection shall be 

 made at the place of manufacture prior to shipment, unless otherwise specified, and shall be so 

 conducted as not to interfere unnecessarily with the operation of the works. 



18. Rejection, (a) Unless otherwise specified, any rejection based on tests made in accord- 

 ance with Section 5 shall be reported within five working days from the receipt of samples. 



(6) Material which shows injurious defects subsequent to its acceptance at the manufacturer's 

 works will be rejected and the manufacturer shall be notified. 



19. Rehearing. Samples tested in accordance with Section 5, which represent rejected 

 material, shall be preserved for two weeks from the date of the test report. In case of dissatis- 

 faction with the results of the tests, the manufacturer may make claim for a rehearing within that 

 time. 



VIII. FULL SIZE TESTS. 



20. Tests of Eye-Bars, (a) Full size tests of annealed eye-bars shall conform to the following 

 requirements as to tensile properties: 



Tensile strength, Ib. per. sq. in 85,000-100,000 



Yield point, min., Ib. per sq. in 48,000 



Elongation in 18 ft., min., per cent 10 



Reduction of area, min., per cent 30 



(b) The yield point shall be determined by the halt of the gage of the testing machine.

ADOPTED AUGUST 25, 1913. 

 . A. Requirements for Rolled Bars. 



I. MANUFACTURE. 



1 . Process. The steel shall be made by the open-hearth process.

3. Ladle Analyses. An analysis to determine the percentages of carbon, manganese, phos- 

 phorus and sulphur shall be made by the manufacturer from a test ingot taken during the pouring 

 of each melt, a copy of which shall be given to the purchaser or his representative. This analysis 

 shall conform to the requirements specified in Section 2. 



4. Check Analyses. A check analysis may be made by the purchaser from finished material 

 representing each melt, and this analysis shall conform to the requirements specified in Section 2. 



III. PHYSICAL PROPERTIES AND TESTS. 



5. Tension Tests, (a) The bars shall conform to the following requirements as to tensile 

 properties:
