Hordhac 'D’ Waxay muujisaa nooc ka mid ah xaashida iftiinka, loogu talagalay in qarax kasta oo gudaha ah uu ku jiro iyada oo aan waxyeello loo geysan meesha laga soo galo lagana hortago faafitaanka qaraxa dibadda;
IIB waxay qeexaysaa qaybta gaaska la isticmaalo;
T4 waxay muujineysaa in badeecada ugu badan ee sheyga ugu badan heerkulka wuxuu ka hooseeyaa 130 ° C.
