CAMBRIA STEEL. 



Test Specimens. 



10. (a) Tension and bend test specimens for plates shall be taken from the 

 finished product, and shall be of 1 he full thickness of material as rolled. Ten- 

 sion test specimens shall be of the form and dimensions shown in Fig. 1. Bend 

 test specimens shall be IK in. to 2K in. wide, and shall have the sheared 

 edges milled or planed. 



(b) The tension and bend test specimens for rivet bars shall be of the 

 full-size section of material as rolled. 

 Number of Tests. 



11. (a) One tension, one cold-bend, and one quench-bend test shall be 

 made from each plate as rolled. 



(b) Two tension, two cold-bend, and two quench-bend tests shall be 

 made for each melt of rivet steel. 



(c) If any test specimen develops flaws, or if a tension test specimen 

 breaks outside the middle third of the gage length, it may be discarded and 

 another specimen substituted therefor. 



IV. PERMISSIBLE VARIATIONS IN WEIGHT AND QAQE. 

 Permissible Variations. 



12. (a) The. thickness or weight of each sheared plate shall conform to the 

 schedule of permissible variations, Manufacturers' Standard Practice, appended 

 to these specifications. 



(b) The dimensions of rivet bars shall conform to the Manufacturers' 

 Standard Practice governing allowable variations in the size of hot-rolled bars. 



V. FINISH.

13. The finished material shall be free from injurious defects and shall 

 have a workmanlike finish. 



VI. MARKING. 



Marking. 



14. The melt or slab number, name of the manufacturer, grade, and the 

 minimum tensile strength for its grade as specified in section 6 shall be legibly 

 stamped on each plate. The melt or slab number shall be legibly stamped 

 on each test specimen representing that melt or slab. 



VII. INSPECTION AND REJECTION. 

 Inspection. 



15. The inspector representing the purchaser shall have free entry, at all 

 times while work on the contract of the purchaser is being performed, to all 

 parts of the manufacturer's works which concern the manufacture of the 

 material ordered. The manufacturer shall afford the inspector, free of cost, 

 all reasonable facilities to satisfy him that the material is being furnished in 

 accordance with these specifications. All tests and inspection shall be made 

 at the place of manufacture prior to shipment, and shall be so conducted as 

 not to interfere unnecessarily with the operation of the works. 



Rejection. 



16. Material which, subsequent to the above tests at the mills and its 

 acceptance there, develops weak spots, brittleness, cracks or other imperfec-
