UL

UL LLC iyinkampani yokubonisana nokuphepha kwezitifiketi emhlabeni wonke yaseMelika ekomkhulu layo eNorthbrook, e-Illinois. Igcina amahhovisi emazweni angama-46. Isungulwe ngo-1894 njenge-Underwriters 'Electrical Bureau (ihhovisi leNational Board of Fire Underwriters), lalaziwa kulo lonke ikhulu lama-20 leminyaka njengoba Underwriters Laboratories futhi wabamba iqhaza ekuhlaziyweni kokuphepha kweziningi zobuchwepheshe obusha balelo khulu leminyaka, ikakhulukazi ukwamukelwa komphakathi kukagesi kanye nokubhalwa kwamazinga okuphepha kwamadivayisi kagesi nezinto zawo.

I-UL ihlinzeka ngesitifiketi esihlobene nokuphepha, ukugunyazwa, ukuhlola, ukuhlola, ukuhlola, ukululeka kanye nezinsizakalo zokuqeqeshwa ezinhlobonhlobo zamakhasimende, kufaka phakathi abakhiqizi, abathengisi, abahlinzeki benqubomgomo, abalawuli, izinkampani zensiza, kanye nabathengi.

I-Ul ingenye yezinkampani eziningana ezivunyelwe ukwenza uvivinyo lokuphepha yi-US federal agency ne-Health Management (Health) ye-US. I-OSHA igcina uhlu lwamalabhoratri wokuhlola avunyiwe, abizwa ngokuthi amaLabhoratri wokuHlola kaZwelonke.

Umlando

I-Underwriters Laboratories Inc. yasungulwa ngo-1894 nguWilliam Henry Merrill. Ekuqaleni komsebenzi wakhe njengonjiniyela kagesi eBoston, uMerrill oneminyaka engu-25 wathunyelwa ukuyophenya ngeParadise of the Electricity's World Fair's. Lapho ebona amandla akhulayo ensimini yakhe, uMerrill wahlala eChicago ukuthola ama-Underwriters Laboratories.

Ngokushesha uMerrill waya emsebenzini ethuthukisa amazinga, wethula izivivinyo, waklama imishini futhi ethola izingozi. Ngaphandle komsebenzi wakhe e-UL, uMerrill ubesebenza njengonobhala-mgcinimafa weNational Fire Protection Association (ngo-1903-1909) kanye nomongameli (1910 kuya ku-1912) futhi ebelilungu elisebenzayo leChicago Board and Union Committee. Ngo-1916, uMerrill waba ngumongameli wokuqala we-UL.

I-UL yashicilela uhlelo lwayo lokuqala oluthi, “Tin Clad Fire Doors”, ngonyaka ka-1903. Ngonyaka olandelayo, i-UL Mark yakhipha imicibisholo yayo ngombhalo wokucisha umlilo. Ngo-1905, i-UL yasungula i-Label Service yemikhakha ethile yomkhiqizo edinga ukuhlolwa okuningi. Abahloli be-UL benza ukuhlolwa kokuqala kwasefekthri emikhiqizweni enombhalo ezikhungweni zabakhiqizi — umkhuba osalokhu uwuphawu lohlelo lokuhlola nokuqinisekisa izitifiketi ze-UL.

I-UL ikhulise yaba yinhlangano enezikhungo ezingama-Laboratories ezingama-64, izivivinyo kanye nezitifiketi ezisebenzisela amakhasimende emazweni ayi-104. Iphinde yavela ezimpandeni zayo ekuphepheni kukagesi nomlilo ukubhekana nezinkinga ezibanzi zokuphepha, njengezinto ezinobungozi, ikhwalithi yamanzi, ukuphepha kokudla, ukuhlolwa kokusebenza, ukuphepha nokuhambisana nemithetho kanye nokusimama kwemvelo.

Ngo-2012, i-UL yaguqulwa yenziwa yinkampani engenzi nzuzo yaba yibhizinisi elisebenzisela inzuzo.
