2. A classe de ajuste das roscas m\u00e9tricas deve ser de 6g\/6H ou superior, de acordo com os regulamentos relevantes, e a espessura restante da parede no ponto mais profundo de qualquer chanfro ou ranhura de al\u00edvio da rosca interna n\u00e3o deve ser inferior a 2 mm.<\/p>\n\n\n\n
3. As roscas externas NPT com flanges ou tamp\u00f5es de obtura\u00e7\u00e3o devem ter um comprimento efetivo de rosca n\u00e3o inferior \u00e0 dimens\u00e3o \u201cL2\u201d, e o comprimento entre a face da extremidade da flange e a cauda da rosca n\u00e3o deve ser inferior \u00e0 dimens\u00e3o \u201cL4\u201d.
4. As roscas internas NPT devem ser medidas com o calibre de obturador L1 de \u201centerrado\u201d a \u201c2 voltas\u201d.
5. O comprimento da sec\u00e7\u00e3o da rosca externa deve ser de, pelo menos, 8 mm e conter, no m\u00ednimo, 8 passos de rosca. Se a rosca tiver uma ranhura de al\u00edvio, deve ser montada uma anilha integral e n\u00e3o compress\u00edvel ou um dispositivo equivalente para garantir o comprimento de engate da rosca necess\u00e1rio.
