He ʻano paipu paila ʻo GB/T 5310.

ʻO kona mea hana he 20g, 20mng, 25mng. He kila kalapona waena ia me ka manganese liʻiliʻi.

Ua māhele ʻia ka lōʻihi o ka lawe ʻana o ka paipu paila i ʻelua ʻano: ka nui paʻa a me ka nui pālua. Ua helu ʻia ke kumukūʻai pākahi o kēlā me kēia paipu kūloko e like me ka lōʻihi i kuhikuhi ʻia, a ua helu ʻia ke kumukūʻai o kēlā me kēia paipu e like me ke kaumaha maoli.

Hiki ke hoʻokaʻawale ʻia ka unahi pālua i ʻekolu ʻano:

Lula pōkole: hoʻohana ʻia e hoʻopaʻa i ka paipu kila humuhumu kūikawā ma ke kākoʻo;

Paipu kila humuhumu ʻano like me ka mānoanoa like o ka paia (ʻoi aku ka liʻiliʻi o ke anawaena o waho ma mua o 32mm): hoʻohana ʻia no ke ʻano mechanical, nā lako hydraulic me ka pololei kiʻekiʻe o ka dimensional a me ka hoʻopau ʻili maikaʻi o ka paipu kila humuhumu pololei;

Paipu kila humuhumu ʻole maʻamau (ke anawaena o waho ʻoi aku ma mua o 32mm a i ʻole ke anawaena o loko emi ma mua o 40mm): Hoʻohana ʻia no nā ʻāpana kūkulu like ʻole, nā mea hana a me nā ʻāpana mechanical.
