Amapuleti ensimbi asikwa ngobude nobubanzi obudingekayo.
Ukusika imiphetho, ukulinganisa, kanye nokulawula ukuthamba kwenziwa ukuze kuhlangatshezwane nokubekezelelana kobukhulu.
10. Ukulawulwa Kwekhwalithi Nokuhlolwa
Ukuhlolwa kwemishini (amandla okukhiqiza, amandla okudonsa, ukunwebeka), ukuhlaziywa kwamakhemikhali,
Ukuhlolwa komthelela, ukuhlolwa kwe-ultrasound, kanye nokuhlolwa kobukhulu kuqinisekisa ukuhambisana ne-ASTM A588/A588M.
11. Ukupakisha Nokulethwa
Amapuleti apakishwe ngezindlela zokulwa nokugqwala (ukubopha, izivikelo zomphetho, ukugoqa okungangeni manzi)
futhi ithunyelwe ngokwezidingo zamakhasimende.
I-ASTM A588/A588M iyinsimbi yesakhiwo enamandla aphezulu ephansi (i-HSLA) eyaziwa ngokumelana kwayo okuhle kakhulu nokugqwala emoyeni—evame ukubizwa ngokuthi insimbi eshintshashintshayo. Amandla ayo okwenza i-patina evikelayo efana nokugqwala ayenza ifaneleke ukusetshenziswa ngaphandle isikhathi eside ngaphandle kokunakekelwa okuncane.
1. Amabhuloho kanye nobunjiniyela bezakhiwo
Isetshenziselwa ibhuloho eliqinile kanye nezingxenye zesakhiwo ezidinga amandla aphezulu kanye nokusebenza kwangaphandle isikhathi eside.
2. Amaphrojekthi Okwakha Nokuhlobisa Izakhiwo
Ilungele izibuko zokuhlobisa kanye nezici zezwe ezizuzisa ukubukeka kwesimanje okunezimo ezishintshashintshayo.
3. Ukwakhiwa Kwesitimela Nomgwaqo Omkhulu
Kusetshenziswa ezinsikeni zokuvikela, ezinsikeni, nasezingqalasizinda zezokuthutha ezidinga ukumelana nokugqwala okunamandla emoyeni.
4. Izakhiwo Zezimboni
Ifanele amathangi, oshimula, kanye nohlaka lwezimboni oluvezwe emswakama nasezimweni zangaphandle ezinzima.
5. Izicelo Zasolwandle Nasogwini
Isebenza ngokwethembeka emachwebeni, ezikhungweni, nasezindaweni ezisogwini ezifakwe usawoti nomoya omanzi.
6. Imishini Nemishini Yangaphandle
Isetshenziselwa izingxenye zemishini yangaphandle ezidinga impilo ende yesevisi kanye nokumelana nokushisa.
1) Ihhovisi Legatsha - ukwesekwa kwabantu abakhuluma iSpanishi, usizo lokuhlanza impahla, njll.
2) Amathani angaphezu kuka-5,000 esitokweni, anobukhulu obuhlukahlukene
3) Kuhlolwa izinhlangano ezigunyaziwe njenge-CCIC, i-SGS, i-BV, ne-TUV, kanye nokupakishwa okujwayelekile okufanele ulwandle
