Muva nje, i-UL ikhiphe uhlaka Lohlaka Lophenyo Lwe-UL 9540B Lokuhlolwa Komlilo Okukhulu Kwezinhlelo Zokuhlala Zebhethri Lamandla Okuhlala. Silindele imibuzo eminingi ngakho-ke sinikeza izimpendulo kusengaphambili.

Q: Iyini isizinda sokuthuthukiswa kwe-UL 9540B?

IMP: Ezinye Iziphathimandla Ezinegunya (AHJs) e-United States zibonise ukuthi uchungechunge lokuhlola lwe-UL 9540A lulodwa alwanele ukuhlangabezana nezimfuneko ze-California Fire Code yango-2022, okudinga ukuhlolwa okwengeziwe komlilo okukhulu. Ngakho-ke, i-UL 9540B yathuthukiswa ngokusekelwe kokufakwayo okuvela eminyangweni yomlilo, ehlanganisa isipiliyoni sokuhlola se-UL 9540A, okuhloswe ngaso ukubhekana nokukhathazeka okuvela kuma-AHJ ahlukahlukene kanye neminyango yomlilo.

Q: Uyini umehluko phakathi kwe-UL 9540A ne-UL 9540B?

A:

1. Ububanzi: I-UL 9540B iqondise ngokukhethekile amasistimu okugcina amandla okuhlala angama-20 kWh noma ngaphansi, ngaphandle kwezinhlelo zokugcina amandla ezentengiso noma zezimboni.
2. Okuqukethwe Kokuhlola: I-UL 9540A idinga ukuhlolwa kuseli, imojula, namaleveli eyunithi, kuyilapho i-UL 9540B idinga kuphela ukuhlolwa kweleveli yeseli nokuhlola ukusabalaliswa komlilo.
3. Umbiko: I-UL 9540A ikhiqiza imibiko yokuhlola emithathu esetshenziselwa ukuhlola amandla esistimu okuphatha ukusakazeka kokubaleka okushisayo ngenxa yamaphutha ebhethri. I-UL 9540B ikhiqiza umbiko owodwa wokuhlola ogxile ekuhloleni ukusabalala komlilo kanye nomthelela wawo oshisayo endaweni ezungezile.

Q: Uma umkhiqizo usuqedile ukuhlolwa kwe-UL 9540A, ingabe ikhona idatha engasetshenziselwa i-UL 9540B?

A: Umbiko wokuhlola wezinga leseli we-UL 9540A ungasetshenziselwa ukuhlolwa kweseli UL 9540B. Nokho, ngenxa yokuthi i-UL 9540B iyindlela yokuhlola ehlukile, ukuhlola ukusabalala komlilo ngaphansi kwe-UL 9540B kusafanele kuqedwe.

Q: Ingabe amasistimu okugcina amandla okuhlala ayadingeka ukuthi ahlolwe ngaphansi kokubili kwe-UL 9540A ne-UL 9540B?

A: Akunjalo. Ukuze uthole isitifiketi se-UL 9540, ngokuya ngamazinga okufaka (NFPA 855, IRC), amasistimu okugcina amandla okuhlala kufanele ahlangabezane nezindinganiso zokusebenza zeleveli yeyunithi ye-UL 9540A lapho isikhala phakathi kwezinhlelo zokulondoloza amandla ebhethri ngamanye singaphansi kwamamitha angu-0.9. Amanye ama-AHJ angase adinge ukuthi abakhiqizi banikeze idatha yokuhlola yokuhlola umlilo omkhulu ngokusekelwe ezimfuneko zomthetho zendawo, njenge-California Fire Code. Nokho, izindlela eziqondile zokuhlola umlilo omkhulu azikakashicilelwa. I-UL 9540B ihlose ukuhlinzeka ngendlela yokuhlola engaguquki yokuhlola umlilo omkhulu ukuze kuhlangatshezwane nalezi zidingo ze-AHJs.

Q:Ingisiza kanjani i-UL 9540B ukuthi ngithole imikhiqizo yami yamukelwe e-US noma kwezinye izimakethe?

A: Isitifiketi se-UL 9540 nokuhlolwa kwe-UL 9540A kuyadingeka ku-UL 9540 ne-NFPA 855 ukuze uthole imikhiqizo yamukelwe e-US nakwezinye izimakethe. Kodwa-ke, ezinye izindawo eNyakatho Melika azicabangi ukuthi i-UL 9540A imele ukuhlolwa komlilo okukhulu njengoba kudingwa ikhodi yendawo yomlilo—isibonelo sango-2022 seKhodi Yomlilo yaseCalifornia. Kulezo zimo, i-Code Authority idinga ukuhlolwa komlilo okukhulu okwengeziwe kwezinhlelo zokugcina amandla okuhlala, futhi kulapho i-UL 9540B ingena khona. I-UL 9540B yathuthukiswa ukuze kubhekwane nokukhathazeka kweziphathimandla zekhodi ezihlobene nezingozi zokusabalalisa umlilo endaweni yokuhlala ye-ESS. isipiliyoni ngenxa yomcimbi wokusabalalisa oshisayo oshisayo.

Q:Ingabe i-UL 9540B ihloselwe ukuba yiZinga?

A: Yebo, kukhona izinhlelo zokwenza i-UL 9540B ifane ne-UL 9540A. Njengamanje i-UL 9540B ikhishwa njengohlaka lokubhekana nezidingo ezisheshayo ze-AHJ.
