Njira Zoyesera Zoyezera Kumatira

Muyezo uwu umaperekedwa pansi pa dzina lokhazikika D 3359; nambala yomwe ikutsatira nthawi yomweyo imasonyeza chaka cha kulera koyambirira kapena, pokonzanso, chaka cha kukonzanso komaliza. Superscript epsilon (e) ikuwonetsa kusintha kwa mkonzi kuyambira kusinthidwa komaliza kapena kuvomerezanso.

1. Kukula

1.1 Njira zoyeserazi zimaphatikiza njira zowunikira makatanidwe amakanema amakutira zitsulo magawo popaka ndi kuchotsa tepi yogwira mtima pa mabala opangidwa mufilimuyo.
1.2 Njira Yoyesera A imapangidwira kuti igwiritsidwe ntchito kumalo ogwirira ntchito pomwe Njira Yoyesera B ndiyoyenera kugwiritsidwa ntchito mu labotale.
ZINDIKIRANI 1—Kutengera kuvomerezana pakati pa wogula ndi wogulitsa, Njira B yoyesera ingagwiritsidwe ntchito ngati mafilimu okhuthala ngati agwiritsidwa ntchito motalikirana motalikirana.
1.3 Njira zoyeserazi zimagwiritsidwa ntchito kutsimikizira ngati kumatira kwa zokutira ku gawo lapansi kuli pa jini.ralmlingo wokwanira. Iwo samasiyanitsa pakati pa magulu apamwamba a adhesion omwe njira zamakono zoyezera zimafunikira.
ZINDIKIRANI 2-Kuyenera kuzindikirika kuti kusiyana kwa kukhazikika kwa ❖ kuyanika kumatha kukhudza zotsatira zomwe zimapezeka ndi zokutira zomwe zimakhala ndi zomatira zomwezo.
1.4 Mu machitidwe a multicoat kumamatira kulephera kungathe kuchitika pakati pa malaya kotero kuti kumamatira kwa dongosolo la ❖ kuyanika ku gawo lapansi sikudziwika.
1.5 Miyezo yotchulidwa mu ma SI unit iyenera kuwonedwa ngati muyezo. Miyezo yomwe yaperekedwa m'makolo ndi yachidziwitso chokha.
1.6 Mulingo uwu sikutanthauza kuthana ndi zovuta zachitetezo, ngati zilipo, zomwe zimakhudzana ndi kugwiritsidwa ntchito kwake. Ndi udindo wa wogwiritsa ntchito muyezo uwu kukhazikitsa njira zoyenera zachitetezo ndi thanzi ndikuzindikira momwe zoletsa zimayendera musanagwiritse ntchito.

2. Zolemba Zotchulidwa

2.1 Miyezo ya ASTM:

3. Chidule cha Njira Zoyesera

3.1 Njira Yoyesera A-Kudula kwa X kumapangidwa kudzera mufilimuyi kupita ku gawo lapansi, tepi yowonongeka imayikidwa pamwamba pa odulidwa ndikuchotsedwa, ndipo kumamatira kumayesedwa bwino pamlingo wa 0 mpaka 5.
3.2 Njira Yoyesera B-Mpangidwe wa lattice wokhala ndi mabala asanu ndi limodzi kapena khumi ndi limodzi kumbali iliyonse umapangidwa mufilimu kupita ku gawo lapansi, tepi yowonongeka imayikidwa pamwamba pa latisi ndiyeno imachotsedwa, ndipo kumamatira kumawunikidwa poyerekeza ndi mafotokozedwe ndi mafanizo.

4. Kufunika ndi Kugwiritsa Ntchito

4.1 Ngati zokutira ndikukwaniritsa ntchito yake yoteteza kapena kukongoletsa gawo lapansi, liyenera kumamatira kwa moyo wawo wonse wautumiki. Chifukwa gawo lapansi ndi kukonzekera kwake pamwamba (kapena kusowa kwake) kumakhudza kwambiri kumamatira kwa zokutira, njira yowunikira kumamatira kwa zokutira ku magawo osiyanasiyana kapena mankhwala apamwamba, kapena zokutira zosiyanasiyana ku gawo lapansi lomwelo ndi chithandizo. zothandiza kwambiri m'makampani.
4.2 Zoletsa za njira zonse zomatira komanso malire a njira yoyeserayi kuti achepetse zomatira (onani 1.3) ziyenera kuzindikirika musanagwiritse ntchito. Kulondola kwa ma labotale ndi njira yoyeserayi ndi yofanana ndi mayeso ena omwe amavomerezedwa ndi anthu ambiri a zitsulo zokutidwa (mwachitsanzo, Test Method D 2370 ndi Test Method D 4060), koma izi ndi zotsatira zake chifukwa chosakhudzidwa ndi onse. koma kusiyana kwakukulu mu zomatira. Chiwerengero chochepa cha 0 mpaka 5 chinasankhidwa mwadala kuti tipewe malingaliro olakwika okhudza kukhala okhudzidwa.
