Tai labiausiai pripa\u017eintos tarptautin\u0117s elmendorfo ply\u0161imo bandymo atlikimo gair\u0117s.<\/p>

    Pagrindiniai standarto aspektai:<\/p>

    Apimtis ir taikymas<\/h3>

    ASTM D1922 standartas skirtas pl\u0117vel\u0117ms, kuri\u0173 storis yra ma\u017edaug iki 0,25 mm. Jis skirtas pramon\u0117s \u0161akoms, kuriose reikia tiksliai palyginti pana\u0161i\u0173 med\u017eiag\u0173 atsparum\u0105 ply\u0161imui, ypa\u010d lanks\u010dioms pakuot\u0117ms ir medicinos prietais\u0173 pakuot\u0117ms.<\/p>

    Testo principas<\/h3>

    Tiksliai sukalibruota \u0161vytuokl\u0117 pertraukia bandin\u012f per fiksuot\u0105 ilg\u012f. . \u0161vytuokl\u0117s energijos nuostoliai<\/strong> tiesiogiai priklauso nuo j\u0117gos, reikalingos ply\u0161iui paskleisti. Taikant \u0161\u012f metod\u0105 u\u017etikrinamas nuoseklus deformacijos greitis, pana\u0161us \u012f realiai naudojam\u0105.<\/p>

    Bandini\u0173 paruo\u0161imas<\/h3>
    • Standartinis a\u0161ar\u0173 ilgis: 43 mm<\/strong><\/li>
    • Bandini\u0173 tipai: sta\u010diakampio arba pastovaus spindulio<\/li>
    • Ply\u0161ys: 20 mm gylio<\/li>
    • Patikrinti nurodymai: MD ir TD<\/li>
    • Ma\u017eiausias egzempliori\u0173 skai\u010dius pagal krypt\u012f: de\u0161imt<\/strong><\/li><\/ul>

      Tinkama bandinio geometrija yra labai svarbi norint pa\u0161alinti nuokrypius, atsirandan\u010dius d\u0117l \u012fstri\u017eo ply\u0161imo ar med\u017eiagos anizotropijos.<\/p>

      Aplinkos kondicionavimas<\/h3>

      ASTM D1922 reikalauja, kad bandiniai b\u016bt\u0173 kondicionuojami 23 \u00b1 2\u00b0C<\/strong> ir 50 \u00b1 10% RH<\/strong> ne ma\u017eiau kaip 40 valand\u0173. Taip stabilizuojamos mechanin\u0117s savyb\u0117s ir u\u017etikrinamas atkuriamumas.<\/p>

      Matavimas ir skai\u010diavimas<\/h3>

      Priklausomai nuo prietaiso konfig\u016bracijos, rezultatai i\u0161rei\u0161kiami milinewtonais (mN) arba gf. Esant standartinei \u0161vytuokl\u0117s talpai, ply\u0161imo j\u0117ga apskai\u010diuojama pagal skal\u0117s rodmenis, pakoreguotus pagal bandinio stor\u012f ir sluoksni\u0173 skai\u010di\u0173.<\/p>
