（ʻO ka ʻāpana kea o ke kaula palekana maoli）
Ma ke kaula ʻo Dingzun,hōʻike kā mākou mau kaula IS i kahiʻūpā waho LSZH polū māmā (RAL 5015)me ka māka Ex-ia/Ex-ib paʻa, e hōʻoiaʻiʻo ana i ka mālama koke ʻia ʻana o nā wahi pōpilikia.

Papa 3: No ke aha he mea nui ʻo Cc a me Lc no ka palekana kūloko

ʻO ke ʻano hōʻoia:
