Maqolada polimer materiallarni mexanik va fizik sinovdan o‘tkazish usullari O‘zbekiston milliy standartlari hamda ISO va ASTM xalqaro standartlari asosida tahlil qilindi. Sinov metodikalari solishtirilib, grafik va statistik tahlilga asoslangan zamonaviy yondashuvlar orqali sinov aniqligini oshirish bo‘yicha amaliy takliflar ishlab chiqildi.
