          A1: Tas \u201eDart Drop\u201c sm\u016bgio bandymas<\/strong> matuoja plastikini\u0173 pl\u0117veli\u0173 atsparum\u0105 sm\u016bgiams, nustatydamas j\u0117g\u0105, reikaling\u0105 med\u017eiagai sulau\u017eyti esant nustatytam sm\u016bgiui.<\/p>

          2 klausimas: Kas yra ASTM D1709?<\/strong>
          A2: ASTM D1709<\/strong> yra standartinis bandymo metodas, skirtas matuoti dart'o kritimo sm\u016bgis<\/strong> plastiko pl\u0117veli\u0173 atsparumas, apibr\u0117\u017eiant bandymo proced\u016bras, \u012frang\u0105 ir skai\u010diavimo metodus.<\/p>

          3 klausimas: Koki\u0105 naud\u0105 gamintojams teikia \u201eDart Drop\u201c sm\u016bgio bandymas?<\/strong>
