Shuning uchun ichkarida diametri devor qalinligining 10 foiziga teng yoki undan yuqori bo'lishi mumkin. Shuningdek, izohni ko'rish.
^b	Ichki diametri 1/2 dan kam bo'lgan bu naychalar uchun Izohli a qo'llanilmaydi. Shuning uchun, ichki diametrli diametrli diametrli tashqi diametrli balansda, Tiis stolida ko'rsatilgan bag'rikenglik va 9-jadvalda ko'rsatilgan devorga toqat ko'rsatiladi.
^c	Tashqi diametrning 3% dan kam bo'lgan devor qalinligi ma'lum miqdorda buzmasdan to'g'ri tekislanmagan holda tekislash mumkin emas. Binobarin, bunday naychalar, bu stolda o'rtacha diametri va ichkarida diametri borasida, bu stolda ko'rsatilgan bardoshli diametri 1/2%, bu stolga qo'shimcha ravishda.
