Washington DC - I-American Iron and Steel Institute (AISI) ishicilele i-AISI S250-21, "North American Cold Formed Steel Building Envelope Heat Transfer Standard, 2021 Edition," njengomthombo owodwa wokubala i-coefficient yokudlulisa ukushisa ezindongeni. equkethe uhlaka lwensimbi olwakhiwe ngendlela ebandayo kanye (nezingxenye ze-U-factor) zosilingi/zegobolondo lophahla. Izinga lenzelwe ukutholwa kanye nokusetshenziswa e-United States, Canada nase-Mexico futhi liyatholakala ukuze lilandwe mahhala ku-www.aisistandards.org.
I-AISI S250-21 yakhelwe ukuthi ekugcineni ithathele indawo yezindlela eziningi kumakhodi nezindinganiso zamanje zamandla ahlukahlukene, iningi lazo elikhawulelwe ekufakweni kodonga okungu-16″ noma okungu-24″ kumafreyimu esikhungo sedatha. Izinketho ezijwayelekile zezibalo zihlukaniswe zibe:
I-AISI S250-21 ihloselwe ukumela izinga elilandelayo lokuhlaziywa ngendlela eyaziwayo yesizinda esishintshiwe, eyadalwa ekuqaleni ngo-1997. Izinzuzo ze-AISI S250-21 ngaphezu kwazo zonke izindlela zokubala zangaphambilini yikhono lokuhlaziya imihlangano yodonga enezici ezilandelayo. :
I-AISI Framework Standards Committee idale ispredishithi ukwenza izibalo zezibalo ngokuhambisana ne-AISI S250-21. Leli thebula litholakala ngokukhululekile futhi linciphisa kakhulu isikhathi esidingekayo ukuze kubalwe izingxenye ezihlukahlukene zemvilophu ngokuvumelana nezinga.
I-AISI isebenza njengezwi lenqubomgomo kahulumeni embonini yensimbi yase-US futhi ikhuthaza insimbi njengento ekhethwayo emakethe. I-AISI iphinde ibambe iqhaza eliphambili ekuthuthukisweni nasekusetshenzisweni kwemikhiqizo emisha yensimbi kanye nobuchwepheshe bokwenza insimbi. I-AISI yakhiwe ngabakhi bensimbi abaneziko ezihlanganisiwe ze-arc kanye namalungu ahlobene angabahlinzeki noma amakhasimende embonini yensimbi. Ukuze ufunde kabanzi ngensimbi nokusebenza kwayo, vakashela iwebhusayithi ye-AISI ku-www.steel.org. Landela i-AISI ku-Facebook noma ku-Twitter (@AISIsteel).
