Sistemet e tubacioneve plastike - Nyje mekanike ndërmjet pajisjeve dhe tubave me presion - Metoda e provës për qëndrueshmërinë ndaj tërheqjes së jashtme nën forcën gjatësore konstante (ISO 3501:2015)
Plastics piping systems - Mechanical joints between fittings and pressure pipes - Test method for resistance to pull-out under constant longitudinal force (ISO 3501:2015)
ISO 3501:2015 specifies a method for checking the ability of assembled uniaxial joints between fittings and plastic pressure pipes to withstand longitudinal tensile stresses. The test applies regardless of the design and material of the fitting used for jointing plastics pipe. This test method is not applicable to fusion-welded joints.
