STANDARD SPECIFICATIONS 



193. Schedule of Requirements. The chemical and physical 

 properties shall conform to the following limits: 



The hard-steel grade will be used only when specified. 



194. Chemical Determinations. In order to determine if 

 the material conforms to the chemical limitations prescribed in 

 Par/ 193, analysis shall be made by the manufacturer from a 

 test ingot taken at the time of the pouring of each melt or blow 

 of steel, and a correct copy of such analysis shall be furnished 

 to the engineer or his inspector. 



195. Yield Point. For the purpose of these specifications,, 

 the yield point shall be determined by careful observation of the 

 drop of the beam of the testing machine, or by other equally 

 accurate methods. 



196. Form of Specimens. 



(a) Tensile and bending-test specimens may be cut from 

 the bars as rolled, but tensile and bending-test specimens 

 of deformed bars may be planed or turned for a length 

 of at least 9 in. if deemed necessary by the manufacturer 

 in order to obtain uniform cross-section. 



(6) Tensile and bending-test specimens of cold-twisted bars 

 shall be cut from the bars after twisting, and shall be 

 tested in full size without further treatment, unless 

 otherwise specified as in (c), in which case the conditions- 

 therein stipulated shall govern. 



(c) If it is desired that the testing and acceptance for cold- 

 twisted bars be made upon the hot-rolled bars before-
