| Cov lus saum toj no muab xam qhov tsawg kawg nkaus elongation qhov tseem ceeb rau ntau yam nominal phab ntsa thicknesses.Qhov twg qhov teev nominal phab ntsa thickness yog nruab nrab rau cov uas qhia saum toj no, qhov tsawg kawg nkaus elongation tus nqi yuav tsum tau txiav txim raws li nram no: | ||||
| Qib | ||||
| 1. E=48t+15.00 | ||||
| 2. E=40t+12.50 | ||||
| 3. E=32t+10.00 | ||||
| qhov twg: | ||||
| E = elongation hauv 2 hauv., %, thiab | ||||
| T = teev nominal phab ntsa thickness, hauv. | ||||
| Sab nraud txoj kab uas hla | Sab nraud txoj kab uas hla ntawm cov yeeb nkab pawg yuav tsum tsis txhob sib txawv ntau tshaj ± 1% ntawm lub cheeb sab nraud. | ||
| Phab ntsa thickness | Phab ntsa thickness ntawm txhua qhov chaw yuav tsum tsis txhob ntau tshaj 12.5% raws li teev tseg nominal phab ntsa thickness. | ||
| Ntev | Cov yeeb nkab yuav tsum tau muab tso rau hauv ib qho ntev ntev, ob npaug ntawm qhov ntev, lossis ntev ntev raws li tau teev tseg hauv daim ntawv xaj, raws li cov kev txwv hauv qab no: | Ib leeg random lengths | 16 txog 25ft (4.88 txog 7.62mm), nti |
| Muab ob npaug rau random lengths | Tshaj 25ft (7.62m) nrog qhov nruab nrab yam tsawg kawg nkaus ntawm 35ft (10.67m) | ||
| Uniform ntev | Ntev raws li tau teev tseg nrog kev tso cai hloov pauv ntawm ± 1 hauv. | ||
| Qhov hnyav | Txhua qhov ntev ntawm cov yeeb nkab yuav tsum tau hnyav nyias thiab nws qhov hnyav yuav tsum tsis txhob sib txawv ntau dua 15% tshaj lossis 5% raws li nws qhov hnyav, suav nrog nws qhov ntev thiab nws qhov hnyav ntawm ib chav tsev ntev. | ||
