Ua hoʻolaha ka NPL National Metrology institute o UK, me ka hui pū ʻana me nā hoa pili honua, i ka lā Malaki 15 i ka hoʻomohala ʻana o ka ISO / IEC maʻamau ISO / TS 21356-1: 2021 no ke ana ʻana i nā waiwai o ka graphene, i kūʻai pinepine ʻia ma ke ʻano pauka a i ʻole .hoʻopuehu wai.ʻO nā kūlana ISO/IEC e hiki ai i nā kaulahao lako ke pane i ka nīnau "He aha kaʻu mea?"a ma muli o ke ʻano hana ma ka NPL Good Practice Guide 145 i hoʻomohala ʻia me ka hui pū ʻana me ke Kulanui o Manchester, UK.

I nā makahiki i hala iho nei, ua neʻe ka graphene ma nā pepa graphene mai ka lab i nā huahana maoli e like me nā kaʻa a me nā smartphones, NPL memo (e nānā i "Grapene 101: Forms, Properties, and Applications").Eia nō naʻe, aia nō kahi keʻakeʻa i ka wikiwiki o kāna kūʻai ʻana, ʻo ia hoʻi ka hoʻomaopopo ʻana i nā waiwai maoli o ka mea.ʻAʻole hoʻokahi wale nō mea, akā he nui, kēlā me kēia me nā waiwai like ʻole e pono e hoʻohālikelike ʻia me nā noi like ʻole e hiki ai i ka graphene ke hāʻawi i nā hoʻomaikaʻi. , a me ka hana ʻana ia mea ʻokoʻa, ka poʻe manaʻolana e hoʻomaikaʻi i kā lākou huahana ma ka hoʻohui ʻana i kekahi mau ʻāpana o ka graphene flakes no nā mea hoʻohana hope ʻaʻole hiki ke hoʻohālikelike ʻia, a laila koho i nā mea kūpono no kā lākou huahana.
