Kotala lapitali wogula ananditumizira kampani ya mpikisano wangamayeso a kupopera mchere pogwiritsa ntchito ndodo ya pansilipoti ndipo ndinafunsa funso limodzi: “Kodi maola 96 ndi abwino?” Yankho langa linamudabwitsa: nambalayo inali mzere wosafunika kwambiri patsamba lino. ASTM B117 ndi njira yogwirira ntchito m'chipinda - imauza labu momwe ingayendetsere chifunga, ndipo imakana kukuuzani momveka bwino zomwe zotsatira zake zikutanthauza pa moyo wautumiki. Chomwe chimasankha ngati lipotilo limateteza pulojekiti yanu ndi chilichonse chokhudza kuwerengera maola: magawo asanu a chipinda, kukonzekera zitsanzo, njira yowunikira, kuwerengera kobwerezabwereza, ndi kuvomerezedwa kwa labu. Ndikuvomereza kapena kukana umboni wa dzimbiri wa ogulitsa mwezi uliwonse, ndipo kalozera uyu ndiye dongosolo lenileni lowerengera lomwe ndimagwiritsa ntchito - ndi manambala omwe ayenera kuwonekera pa lipoti lodalirika, umboni wolembedwa kuti maola opopera mchere sakugwirizana ndi zaka, ndi chowunikira chofiira chomwe mungagwiritse ntchito pa PDF iliyonse yomwe wogulitsa amakutumizirani.
TL;DR — Werengani Lipotilo mu Dongosolo Ili
- ASTM B117 imangofotokoza malo oyesera okha, osati kulephera/kulephera: muyezo wokha umati "supereka mtundu wa chitsanzo cha mayeso kapena nthawi yowonekera ... kapena kutanthauzira komwe kungaperekedwe ku zotsatira" - kotero lipoti lililonse lopanda njira zovomerezeka zomwe wogula amavomereza silikwanira mwa kapangidwe kake.
- Lipoti lodalirika limafotokoza magawo asanu a chipinda: yankho la 5% NaCl, 35°C ± 2°C, pH 6.5–7.2, kuchuluka kwa fog settlement kwa 1.0–2.0 mL/h pa 80 cm², ndi zitsanzo pa 15–30° kuchokera pa vertical; parameter yomwe ikusowa imatanthauza kuti run singathe kubwerezedwanso.
- Maola opopera mchere sasintha kukhala zaka zogwirira ntchito: deta imodzi yolembedwa ikuwonetsa chitsanzo cha maola 200 chomwe chinakhala zaka 20 ku Mumbai pomwe chitsanzo cha maola 144 chinalephera kugwira ntchito m'zaka ziwiri ku New Delhi - mgwirizano wa Pearson wa +0.66 kokha ngakhale pakati pa zigawo zofanana zachitsulo.
- Pa ndodo ya nthaka yolumikizidwa ndi mkuwa, dzimbiri lofiira limangochokera ku chitsulo chowonekera, kotero komwe dzimbiri limawonekera - malekezero odulidwa, ulusi, mizere yolembera - imakuuzani komwe gawo la mkuwa linalephera, ndichifukwa chake zolemba zokonzekera zitsanzo ndizofunikira kwambiri kuposa maola oyambira.
- Chowunikira chathu cha mfundo 8 chomwe chili pansipa chimapereka lipoti lililonse la ogulitsa mumphindi ziwiri; chilichonse chomwe chikusowa mu chipinda, njira yowunikira, kapena kuvomerezedwa kwa labu chimabwereranso ndi mafunso asanavomerezedwe.
Kodi ASTM B117 Ndi Chiyani Kwenikweni — Kachitidwe ka Chipinda, Osati Chigamulo
