Iimeko zeNdibano

Nantsi eminye imiqathango ecetyiswayo yokudityaniswa kwesi sitywini:

1. Isitywina kufuneka sifakwe kwindawo ecocekileyo, eyomileyo nenesandi.Imiphezulu kufuneka ingabi nazingcolisi, njenge-oyile, uthuli, okanye inkunkuma.
2. Idizayini edibeneyo ecetyiswayo kufuneka ilandelwe ukuze kuqinisekiswe ubunzulu be-sealant obuchanekileyo kunye nokubonelela ngekhono lokunyakaza okwaneleyo.
3. Umdibaniso kufuneka ulungiselelwe ukuvumela ubuncinane be-25% ukunyakaza kwi-sealant.
4. Ubushushu be-ambient ngexesha lokufaka isicelo kufuneka lube phakathi kwe-5 ° C ukuya ku-40 ° C (41 ° F ukuya ku-104 ° F) ukuze ufumane iziphumo ezizezona zilungileyo.
5. Umswakama ohambelanayo ngexesha lokufaka isicelo kufuneka ube ngaphantsi kwe-80% ukukhusela ukufuma ekuphazamiseni inkqubo yokunyanga.
