Hōʻike kēia hōʻailona i ka hui ʻana o nā mea uila i hoʻokahi a ʻoi aku paha nā ʻano pahū i nā kūlana pahū.;
E like me nā kikoʻī i wehewehe ʻia ma ka ʻatikala 29 o ke kūlana GB3836.1-2010, he koi no lako uila pahū e hapai i ka mea maopopo “Ex” e kaha ana ma kahi kūlana koʻikoʻi ma kona kino waho. Eia hou, Pono ka papa inoa o ka mea hana e hōʻike i ka hōʻailona pahū pono me ka helu hōʻoia e hōʻoia i kona

Nānā: Hōʻike ka papa ʻaina i nā ʻano pale pahū maʻamau no nā mea uila, e hōʻike ana i kahi hui o nā ʻano pale pahū like ʻole e hana i nā ʻano pale pale pahū hybrid.

ʻo kahi laʻana, ka hoailona ana “Ex demb” hōʻike i kahi ʻano pale pahū hybrid no nā mea uila, hookomo ana pale ahi, hoʻonui i ka palekana, a me nā ʻano encapsulation.

ʻO ka hoʻokaʻawale ʻana o nā ʻāpana i nā wahi e pili ana i nā pōʻino pahū kinoea:

Ma na wahi e pahū ai na kinoea a me hikiwawe hui pū nā mahu me ka ea e hana i nā hui kinoea pahū, ua hoʻokumu ʻia nā ʻāpana ʻāpana ʻekolu e pili ana i ka pae o ka pilikia:
