A Qhov tsawg kawg nkaus elongation ntawm gauge ntev 2in. (50mm) yuav tsum tau txiav txim los ntawm cov qauv hauv qab no:

e=625000(1940)A^0.2/U^0.9

e = qhov tsawg kawg nkaus elongation ntawm lub ntsuas 2in. (50mm), qhov feem pua tawm mus rau qhov ze tshaj 0.5%;

A = Muab xam raws li cov txheej txheem sab nraud ntawm lub nominal raj los yog lub nominal dav ntawm cov qauv tensile thiab nws cov phab ntsa thickness, thiab sib npaug mus rau qhov ze tshaj plaws cross-sectional cheeb tsam ntawm lub tensile qauv ntawm 0.01 in.2 (1 mm2), thiab Nws muab piv nrog 0.75in.2 (500mm2), qhov twg me dua.
