Imidoda eziNtloko: Izimo Eziphambiliyo kwaye yeNkqubo

Iindlela zenkqubo yezinto zokwenene ziyagcinwa ngokukhulu kwiindawo ezisebenzisayo, ezingcono nezomphakathi ngokuba yinkqubo yazo, ubungcola nokulondoloza ukugxula. Ukuyiqiniseka iindlela ezi zilandela izikhali eziphambili zokuphepha nokusebenza, kufuneka zilandelane neembande zokwenyani-ke ezithile zase Underwriters Laboratories (UL) kunye nendawo ye American National Standards Institute (ANSI).

Iimbande ze UL: Ukuqinisekisa ukuphatha kwezinto kunye nokulondoloza ukugxula

UL iyasemgangathweni esijwayelekileyo ngokuphephayo, inika amanqobo okulungiswa oluthileyo kwiindlela zenkqubo yezinto. Iimbande eziphambili zifaka phakathi:

UL 10C–Iqinisekisa iindlela ezinele ukugxula, ibonisa inkqubo yazo yokungenela ukuguqulelwa kwegxula (ngaphandle kweentsuku eziyi20 kuya kweentsuku eziyi180). Le ndlela zinezixhobo lokugcina amadoda kunye nezinto.

UL 1784–Iqokelela kakhulu kulo mgca wokuqinisekisa ukuphatha kwegxula, uyenza le ndlela ingavumele ukungena kwento yegxula kakhulu-ngokuqinisekisa ukuphatha kwegxula-eyona nto enkulu kakhulu kwiindleleni zokubulawa, ikhankatha kunye neesikole.

Iimbande ze ANSI: Ubunzima kunye nokusebenza

U-ANSI uphuhlise ngezinye iindlela zokwenza ngokwesiko sokuqinisa indlela ephumelelayo kunye neemeko zokusebenza. Kwiimeko eziphambeneyo kuxhomekeke kwezi:

ANSI/SDI A250.8–Isicaciso sokuphepha kwamanzi, ukulawula ngokuphefumlelayo, kunye nokudura kakhulu, ke ngoko iindonga zasekileyo ziyafuneka zibe yile ndonga ezikhankanywayo.

ANSI/BHMA A156.3–Isicaciso seendlela zokukhipha, ukuqinisekisa ukuba kuyathola isisombululo esithembekileyo ngokufanelekileyo neemeko zezakhiwo.

Ngubani na ukuthetha kweemeko

Ukucetyiswa kwiimeko ze-UL kunye ne-ANSI zinika iindlela ezilungileyo:

✔Ukuphephileyo oluninzi–Iindlela enamnandi yesenzo kunye nemoya okungenakho ukugcina abantu ngemzuzu yokungenelwa.

✔Ukucetyiswa kweemeko–Iyafaka phakathi iindlela zokwenza zakasemaphandleni, ukuzigxila ngokulandelana nokulawulwa kwezakhiwo.

✔Ukudura kakhulu ngokudala–Kunceda izindleko zokuphucula kunye nokudlulisela umgca wokuphila kwendonga.

✔Ukuphela kwezibongeli–Ibonisa ukucetyiswa kwiimeko eziphemelekileyo zokuphephileyo.

Ngokucetyiswa kwiimeko ze-UL kunye ne-ANSI, abachazi iindlela kunye nabasebenzisi bokwelanelwa baqinisekisa ukuba iindlela zasekileyo zenze umsebenzi opheleleyo, ubude bekhona kunye neempumelelo ngaso sonke isicathami.
