M'mimba mwake mwadzina
Kukula mwadzina DN ndi kuchuluka kwa manambala a zida zonse zamapaipi mu mapaipi kuti asiyanitse magawo omwe awonetsedwa ndi ulusi kapena m'mimba mwake. Diameter mwadzina ndi nambala yozungulira yomwe imagwiritsidwa ntchito ngati chizindikiritso ndipo sichofanana ndi kukula kwa makina.
Kukula mwadzina kumalembedwa ndi chilembo "DN" chotsatiridwa ndi manambala. Ngati m'mimba mwake mwadzina ndi 250mm, iyenera kulembedwa ngati DN250. Mavavu ambiri amatchulidwa mu Table 1-44.

Zindikirani: zilembo zolimba patebulo zimagwiritsidwa ntchito modziwika bwino.
Kupanikizika mwadzina
PN ndi chizindikiro cha manambala chokhudzana ndi kukakamizidwa. Ndi nambala yozungulira yoyenera kuti mufotokozere. Zoyika zonse zamapaipi zokhala ndi m'mimba mwake DN zomwe zimawonetsedwa ndi kukakamiza kwadzina P ndipo mtengo uzikhala ndi kukula kofananira kogwirizana ndi mtundu wolumikizira kumapeto.
Ku China, pamene kukakamizidwa mwadzina kumakhudzidwa, pofuna kumveka bwino, gawo la muyeso limaperekedwa ngati "MPa".
Ku Britain, United States ndi maiko ena, ngakhale lingaliro la kukakamizidwa mwadzina laphatikizidwa mumiyezo yoyenera, koma kugwiritsa ntchito kwenikweni dongosolo la Britain akadali>
Pali dongosolo la "K" m'miyezo ya ku Japan, monga 10K, 20K, 40K, ndi zina zotero. Lingaliro la msinkhu wa kuthamanga ndilofanana ndi dongosolo la kupanikizika mu dongosolo la Britain, koma gawo la kuyeza ndi metric. Ubale pakati pa "K" mulingo ndi mulingo wopanikizika ukuwonetsedwa mu Gulu 1-46.
