Njengophuhliso loluntu, abathengi abaninzi ngakumbi nangakumbi abavela kwiimarike ezahlukeneyo bakhathalele impilo yelungu losapho kunye nokhuseleko ngexesha lokukhethwa kwezinto zokwakha zeplastiki zokhuni.Ngakolunye uhlangothi, sigxininise kwizinto ezidibeneyo ngokwayo ukuze siqinisekise ukuba ziluhlaza kwaye zikhuselekile kwaye ngakolunye uhlangothi, siyayikhathalela ukuba ingasikhusela kwenye intlekele njengomlilo.
Kwi-EU, ulwahlulo lomlilo lweemveliso zokwakha kunye nezinto zokwakha yi-EN 13501-1: 2018, eyamkelwe kuyo nayiphi na ilizwe le-EC.
Nangona ulwahlulo luya kwamkelwa kulo lonke elaseYurophu, oko akuthethi ukuba uya kukwazi ukusebenzisa imveliso kwiindawo ezifanayo ukusuka kwilizwe ukuya kwelinye ilizwe, njengoko isicelo sabo esikhethekileyo sinokwahluka, ezinye iimfuno zenqanaba B, ngelixa ezinye zinokufuna izinto. ukufikelela kwinqanaba A.
Ukucacisa ngakumbi, kukho amacandelo omgangatho kunye ne-cladding.
Ngomgangatho, umgangatho wokuvavanya ngokuyintloko ulandela i-EN ISO 9239-1 ukugweba ukukhutshwa kobushushu obubalulekileyo kunye ne-EN ISO 11925-2 Exposure = 15s ukubona idangatye lisasazeka ukuphakama.
Ngelixa i-cladding, uvavanyo lwenziwa ngokuhambelana ne-EN 13823 ukuvavanya igalelo elinokubakho lemveliso kuphuhliso lomlilo, phantsi kwemeko yomlilo elingisa into enye evuthayo kufutshane nemveliso.Nazi izinto ezininzi, ezifana nesantya sokukhula komlilo, izinga lokukhula komsi, umsi opheleleyo kunye nexabiso lokukhululwa kobushushu kunye nokunye.
Kwakhona, kufuneka ihambelane ne-EN ISO 11925-2 Exposure=30s njengovavanyo lomgangatho kufuneka kujongwe imeko yokuphakama kwedangatye.
i-USA
Kwimakethi yase-USA, esona sicelo siphambili kunye nolwahlulo lwe-retardant yomlilo
IKhowudi yoKwakha yaMazwe ngaMazwe (IBC):
Udidi A: FDI 0-25；SDI 0-450;
Udidi B: FDI 26-75;SDI 0-450;
Udidi C: FDI 76-200;SDI 0-450;
Kwaye uvavanyo lwenziwa ngokwe-ASTM E84 ngokusebenzisa izixhobo zeTunnel.I-Flame Spread Index kunye ne-Smoke Development Index ziyidatha ephambili.
Ewe kunjalo, kwamanye amazwe, njengeCalifornia, banesicelo sabo esikhethekileyo kubungqina bomlilo wasendle wangaphandle.Ke ngoko kuyilwe phantsi kovavanyo lomlilo wedekhi ngokweCalifornia Referenced Standards Code (Isahluko 12-7A).
INQANABA LOKUHLASELA EMHLATHENI WASE-AUS (BAL)
GH 3959, lo Mgangatho ubonelela ngeendlela zokumisela ukusebenza kwezinto zokwakha zangaphandle xa zibekwe kubushushu obukhanyayo, amalahle avuthayo kunye nobutyobo obutshayo.
Kukho amanqanaba ama-6 ohlaselo lomlilo wamatyholo ewonke.
Ukuba ufuna ukwazi ngakumbi malunga novavanyo ngalunye okanye isicelo semarike, nceda uzive ukhululekile ukusishiya umyalezo.
