Iyini Isici Sokuphepha esingu-7:1 futhi Kungani Ibalulekile?

Isilingi esiphakamisayo esinesici sokuphepha esingu-7:1 sinamandla okuphuka aphindwe kasikhombisa komkhawulo womthwalo olinganiselwe wokusebenza. Lokhu kusho ukuthi isihlilingi esilinganiselwe ngethani elingu-1 kufanele simelane okungenani namathani ayi-7 ngaphambi kokuhluleka. Isici sokuphepha esingu-7:1 sigunyazwe amazinga abalulekile womkhakha afaka i-EN 1492-1, EN 1492-2, kanye ne-AS 4497:2018 yezihlilingi zokwenziwa . Lesi sihloko sichaza umehluko phakathi kwesici sokuphepha nomkhawulo womthwalo osebenzayo, kungani u-7:1 kuyindinganiso yezihlilingi zokwenziwa, ukuthi iqhathaniswa kanjani nezinye izinhlobo zemishini, nokuthi kungani le majini yokuphepha ibalulekile ekuvikelweni kwezisebenzi nezimpahla emisebenzini yokuphakamisa umhlaba wangempela.
