| Abstract: | First,in order to evaluate the uncertainty of testing tensile strength for steel,various factors influencing on testing results for hot-rolled ribbed bar of Ф18 mm were determined by means of math model as an example,the related components of effective factor were calculated.Then,the uncertainty compound of combined standard and expanded were determined.Finally,the report on tested tensile strength of hot-rolled ribbed bar are given. |
