Detta test \u00e4r avg\u00f6rande f\u00f6r att utv\u00e4rdera nedslag fr\u00e5n en fallande pil<\/strong> f\u00f6rpackningsmaterialens h\u00e5llfasthet. Den hj\u00e4lper tillverkare att bed\u00f6ma risken f\u00f6r att filmen g\u00e5r s\u00f6nder vid hantering och transport.

Standarden beskriver tv\u00e5 olika provningsmetoder:<\/p>

  1.

  2. Testmetod B<\/strong>: I den h\u00e4r metoden anv\u00e4nds en st\u00f6rre dart med en 50,80 mm (2,000 tum)<\/strong> ett halvsf\u00e4riskt huvud med diametern sl\u00e4pps fr\u00e5n en h\u00f6jd av 1,52 m (60,0 tum)<\/strong>. Denna metod anv\u00e4nds vanligtvis f\u00f6r filmer d\u00e4r det kr\u00e4vs en dart som v\u00e4ger 0,3 kg till 6 kg<\/strong> f\u00f6r att bryta provet.<\/li><\/ol>

Provningsresultaten bidrar till att fastst\u00e4lla materialets \u00f6vergripande slagh\u00e5llfasthet<\/strong>, vilket ger tillverkarna v\u00e4rdefull information f\u00f6r att f\u00f6rb\u00e4ttra f\u00f6rpackningarnas h\u00e5llbarhet.<\/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
