ʻO ka mea hoʻāʻo paʻakikī Universal he mea hoʻāʻo piha ia e pili ana i nā kūlana ISO a me ASTM, e ʻae ana i nā mea hoʻohana e hana i nā hoʻāʻo paʻakikī Rockwell, Vickers a me Brinell ma ka mea hana like. Hoʻāʻo ʻia ka mea hoʻāʻo paʻakikī Universal ma muli o nā kumumanaʻo Rockwell, Brinell, a me Vickers ma mua o ka hoʻohana ʻana i ka pilina hoʻololi o ka ʻōnaehana paʻakikī e loaʻa ai nā waiwai paʻakikī he nui.
He kūpono ke ana paʻakikī HB Brinell no ke ana ʻana i ka paʻakikī o ka hao i hoʻolei ʻia, nā mea hao ʻole-ferrous, a me nā kila like ʻole i hoʻoheheʻe ʻia a hoʻomehana ʻia. ʻAʻole kūpono ia no ke ana ʻana i nā laʻana a i ʻole nā ʻāpana hana i paʻakikī loa, liʻiliʻi loa, lahilahi loa, a ʻaʻole ʻae i nā indentations nui ma ka ʻili.
He kūpono ke ana paʻakikī HR Rockwell no: ka hoʻāʻo ʻana i nā ʻōmole, ke ana ʻana o ka paʻakikī o nā ʻāpana i hoʻopau ʻia, i hoʻopau ʻia a me nā ʻāpana i mālama ʻia me ka wela.
He kūpono ke ana paʻakikī ʻo HV Vickers no: ke ana ʻana i ka paʻakikī o nā laʻana a me nā ʻāpana me nā wahi liʻiliʻi a me nā waiwai paʻakikī kiʻekiʻe, ka paʻakikī o nā papa i komo a i ʻole nā uhi ma hope o nā ʻano hana ʻili like ʻole, a me ka paʻakikī o nā mea lahilahi.
Eia ka hoʻolauna ʻana i ka moʻo hou o nā mea hoʻāʻo paʻakikī Universal: a me ka pale paʻi Universal Hardness Tester
ʻOkoʻa mai ka mea hoʻāʻo paʻakikī Universal kuʻuna, hoʻohana ka hanauna hou o ka mea hoʻāʻo paʻakikī Universal i ka ʻenehana ʻike ikaika a me ka ʻōnaehana manaʻo ikaika pani ʻia e pani i ke kumu hoʻohālike hoʻouka kaumaha, e maʻalahi ai ke ana a ʻoi aku ka paʻa o ka waiwai i ana ʻia.
