\u015eu anda g\u00f6zeneklili\u011fi belirlemeye y\u00f6nelik iki temel y\u00f6ntem bulunmaktad\u0131r.
\nBunlardan biri, Ar\u015fimet yasas\u0131na g\u00f6re filtre plakas\u0131ndaki deli\u011fin hacmini hesaplamakt\u0131r; yani, su ta\u015fma borusundan d\u0131\u015far\u0131 akmaya ba\u015flayana kadar ta\u015fma borusu bulunan cam beher i\u00e7ine su enjekte etmektir.
\nSu art\u0131k d\u0131\u015far\u0131 akmad\u0131\u011f\u0131nda, su tahlil edilecektir.
\nT\u00fcm numuneler suya dikkatlice yerle\u015ftirildi, ard\u0131ndan ta\u015fma borusundan su bo\u015falt\u0131ld\u0131 ve o k\u0131s\u0131mdaki su miktar\u0131 \u00f6l\u00e7\u00fcld\u00fc.
\nTa\u015fma suyunun hacmi, filtre plakas\u0131n\u0131n fiziksel hacminden \u00e7\u0131kar\u0131l\u0131r; bu hacim, filtre plakas\u0131ndaki deliklerin toplam hacmidir.
\nBa\u015fka bir y\u00f6ntem ise, test edilecek numunenin ger\u00e7ek yo\u011funlu\u011funu ve y\u0131\u011f\u0131n yo\u011funlu\u011funu s\u0131ras\u0131yla belirlemek ve ard\u0131ndan a\u015fa\u011f\u0131daki form\u00fcle g\u00f6re numunenin g\u00f6zeneklili\u011fini hesaplamakt\u0131r.
\nHer iki y\u00f6ntemin de art\u0131lar\u0131 ve eksileri vard\u0131r.
\n\u00c7al\u0131\u015fma y\u00f6ntemi basit ve kullan\u0131\u015fl\u0131d\u0131r; alg\u0131lama h\u0131z\u0131 da y\u00fcksektir; ancak en b\u00fcy\u00fck dezavantaj\u0131, filtre plakas\u0131 malzemesinin su emme \u00f6zelli\u011fi nedeniyle tahliye kapasitesinin ger\u00e7ek deplasman de\u011ferinden daha d\u00fc\u015f\u00fck olmas\u0131d\u0131r. Bu durum, \u00f6l\u00e7\u00fcm verilerinin ger\u00e7ek de\u011ferden daha d\u00fc\u015f\u00fck \u00e7\u0131kmas\u0131na neden olur.
\n\u0130kinci y\u00f6ntemin test s\u00fcreci karma\u015f\u0131k olsa da, test s\u0131ras\u0131nda filtre plakas\u0131 malzemesinin su emme oran\u0131n\u0131n etkisi ortadan kald\u0131r\u0131l\u0131r ve elde edilen veriler nispeten do\u011frudur.
\nBu standartta, g\u00f6zeneklilik indeksi 84%\u2019den b\u00fcy\u00fck olarak belirlenmi\u015ftir.<\/p>\n
