ASTM D1709 ja ISO 7765 m\u00e4\u00e4ratlevad standardmenetlused, milles m\u00e4\u00e4ratakse kindlaks noolte suurused, langemisk\u00f5rgused, konditsioneerimisn\u00f5uded ja arvutusmeetodid 50% rikkeenergia m\u00e4\u00e4ramiseks (tuntud ka kui l\u00f6\u00f6gikahjustuse raskus<\/strong>). Kuna see katse kajastab kile koostise, ekstrusiooni kvaliteedi ja paksuse \u00fchtluse kombineeritud panust, kasutatakse seda laialdaselt kile tootmisel, toidupakendites, farmaatsiatoodete blisterdamismaterjalides ja paljudes paindlike pakendite rakendustes.<\/p>

Tootjad tuginevad sellele testile sageli spetsifikatsioonide koostamisel, uute materjalide kvalifitseerimisel ja tavap\u00e4rase kvaliteedikontrolli l\u00e4biviimisel.

ASTM D1709 sisaldab kahte katsemeetodit:<\/p>

  • Meetod A kasutab 38,10 mm<\/strong> tikapea, langetatud 0.66 m<\/strong>, ideaalne filmide jaoks, mis n\u00f5uavad kaalu alates 50 g kuni 6 kg<\/strong>.<\/li>
  • Meetod B kasutab 50,80 mm<\/strong> tikapea, langetatud 1.52 m<\/strong>, sobib filmide jaoks, mis n\u00f5uavad 0,3 kg kuni 6 kg<\/strong>.<\/li><\/ul>

    Need kaks meetodit annavad tulemusi, mis ei saa otseselt v\u00f5rrelda<\/strong> sest noole suurus, langemisk\u00f5rgus ja l\u00f6\u00f6gienergia on erinevad.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    Alternatiivne r\u00fchmitamismeetod<\/h3>

    Siinkohal katsetatakse k\u00fcmne proovi r\u00fchmi \u00fcheainsa kaaluga ja kaalu muudetakse r\u00fchmade vahel. See meetod on kasulik, kui \u00fcksikasjaliku anal\u00fc\u00fcsi jaoks on vaja laiaulatuslikku eba\u00f5nnestumisjaotust.<\/p>
