ECISS/TC 29/SC 9 - Mechanical testing of tubes

This International Standard specifies a method for determining the ability of full-section metallic tubes of circular cross-section to undergo plastic deformation in bending. It is intended for tubes with an outside diameter no greater than 65 mm, although the range of the outside diameter for which this International Standard is applicable may be more exactly specified in the relevant product standard.
NOTE - Bend tests of the test pieces taken from tubes in the form of transverse strips should be made in accordance with ISO 7438 so as to increase the original curvature of the test piece.

This European Standard specifies the ring hydraulic pressure test for metallic tubes. It is generally applied to tubes with an outside diameter generally greater than 120 mm and outside diameter to thickness ratio not less than 20. The objective of this test is to ascertain the value of the hoop stress required to produce a specified total circumferential (hoop) strain.

This European Standard specifies the drop weight tear test for meatallic materials and includes a method for assessing the fracture appearance of ferritic steels. Assessment can also be based on the energy absorbed in fracturing the test piece, particularly for materials other than ferritic steels.

This European Standard specifies a method for determining the ability of metallic tubes of circular cross section to undergo plastic defermation by flattening. It may also be used to show up defects in the tubes. The Standard is applicable to tubes having an outside diameter not greater than 600mm and a thickness not greater than 15% of the outside diameter. The range of the outside diameter, or thickness, for which this European Standard is applicable may be more exactly specified in the relevant Product Standard.

This European Standard specifies a method for a ring tensile test of tubes to reveal surface and interal defects by subjecting the test piece to strain until fracture occurs. This test may also be used to assess the ductility of tubes. The ring tensile test is applicable to tubes having an outside diameter exceeding 150mm and wall thickness not greater than 40mm. The inside diameter shall be greater than 100mm.

This European Standard specifies a method for a ring expanding test on tubes, that is used to reveal defects both on the surfaces and within the tube wall by expanding the test piece using a drift until fracture occurs. It may also be used to assess the ability of tubes to undergo plastic deformation. The ring expanding test is applicable to tubes having an outside diameter from 18 up to and including 150mm and wall thickness from 2 up to and including 16mm.

This European Standard specifies a method for determining the ability of metallic tubes of circular cross section to undergo plastic deformation during flang formation. It is intended that the Standard should be applicable to tubes having an outside diameter not greater than 150mm and a wall thickness not greater than 10mm. The range of diameters or wall thickness for which this European Standard is applicable may be more exactly specified in the relevant product standard.

This European Standard specifies a method for determining the ability of full- section metallic tubes of circular cross section to undergo plastic deformation in bending. It is inteded for tubes with an outside diameter not greater than 65mm although the range of the outside diameter for which this European Standardis applicable may be more exactly specified in the relevant Product Standard.

This European Standard specifies a method for determining the ability of metallic tubes of circular cross section to undergo plastic deformation by drift expansion. It is intended that the Standard should be applicable to tubes having an outside diameter not greater than 150mm (100mm for light metals) and thickness not greater than 10mm. The range of the outside diameter or thickness for which this European Standard is applicable may be more exactly specified in the relevant Product Standard.
