Metallic materials - Tube - Flattening test (ISO 8492:2013)
ISO 8492:2013 specifies a method for determining the ability of metallic tubes of circular cross-section to undergo plastic deformation by flattening. It may also be used to reveal the defects in the tubes.
ISO 8492:2013 is applicable to tubes having an outside diameter no greater than 600 mm and a thickness no greater than 15 % of the outside diameter. The range of the outside diameter or thickness, for which this International Standard is applicable, may be more exactly specified in the relevant product standard.
Metallische Werkstoffe - Rohr - Ringfaltversuch (ISO 8492:2013)
Diese Internationale Norm legt ein Verfahren zur Bestimmung der Eignung metallischer Rohre mit kreisförmigem Querschnitt fest, einer plastischen Verformung durch Falten unterzogen zu werden. Das Verfahren darf auch zur Sichtbarmachung von Fehlern in den Rohren angewendet werden.
Diese Internationale Norm gilt für Rohre mit einem Außendurchmesser von höchstens 600 mm und einer Wanddicke von höchstens 15 % des Außendurchmessers. Der Bereich des Außendurchmessers oder der Wanddicke, für den diese Internationale Norm gilt, kann genauer in der zutreffenden Produktnorm festgelegt sein.
Matériaux métalliques - Tubes - Essai d'aplatissement (ISO 8492:2013)
L'ISO 8492:2013 spécifie une méthode de détermination de l'aptitude à la déformation plastique par aplatissement de tubes métalliques de section circulaire. Elle peut également être utilisée pour mettre en évidence les défauts des tubes.
La présente Norme internationale est applicable aux tubes de diamètre extérieur au plus égal à 600 mm et d'épaisseur ne dépassant pas 15 % du diamètre extérieur. La gamme de diamètres extérieurs ou d'épaisseurs pour laquelle la présente Norme internationale s'applique, peut être spécifiée de façon plus précise dans la norme de produit concernée.
Kovinski materiali - Cev - Preskus sploščitve (ISO 8492:2013)
Ta mednarodni standard določa metodo za določanje sposobnosti kovinskih cevi s krožnim prerezom, da prenesejo deformacijo na podlagi sploščitve. Lahko se uporablja tudi za odkrivanje hib na ceveh. Ta mednarodni standard se uporablja za cevi z zunanjim premerom, manjšim od 600 mm, in debelino, manjšo od 15 % zunanjega premera. Razpon zunanjega premera ali debeline, za katerega velja ta mednarodni standard, je lahko natančneje določen v ustreznem standardu za izdelek.

Overview
EN ISO 8492:2013 (ISO 8492:2013) specifies a standardized flattening test for metallic tubes with circular cross-sections. The procedure determines the ability of a tube to undergo plastic deformation by flattening and can reveal manufacturing or material defects. The standard applies to tubes with an outside diameter up to 600 mm and a wall thickness up to 15% of the outside diameter; product-specific standards may further narrow the applicable range.
Key Topics
- Test principle: Flatten an end or a cut test piece between two rigid, plane platens until the specified platen separation (H) is reached and inspect for cracking or defects.
- Scope limits: Applicable for circular tubes with OD ≤ 600 mm and thickness ≤ 15% of OD unless otherwise defined in the relevant product standard.
- Test piece: Length between 10 mm and 100 mm; edges may be rounded or chamfered. End-of-tube tests require a cut to at least 80% of OD to the depth equal to the test piece length.
- Equipment: A flattening machine with two parallel rigid platens; platen width must exceed the flattened test piece width (at least 1.6 × D) and platen length must cover the full test-piece length.
- Environmental conditions: General testing at ambient temperature (10 °C to 35 °C); controlled tests at 23 °C ± 5 °C.
- Operational controls: Platens moved perpendicular to tube axis; if disputed, platen speed shall not exceed 25 mm/min.
- Acceptance and inspection: If product standard requirements exist, interpret results accordingly. Otherwise a test piece passes if no cracks are visible without magnification; slight edge cracks are not cause for rejection.
- Test reporting: Minimum report items include reference to ISO 8492, test-piece identification and dimensions, platen distance (H), weld position if relevant, and test result.
Applications
- Quality control: Routine verification of forming and ductility performance for steel and other metallic tubes during production or incoming inspection.
- Defect detection: Reveals laminations, voids, or weakness originating from material defects, welding faults or cold work.
- Product specification compliance: Used by manufacturers and purchasers to demonstrate conformity with tube product standards and contractual requirements.
- Research and development: Comparative assessment of tube fill, wall integrity and joining/welding effects during process development.
Related Standards
- EN ISO 8492:2013 supersedes EN ISO 8492:2004; it is maintained by ISO/TC 164 (Mechanical testing of metals), Subcommittee SC 2 (Ductility testing).
- Refer to relevant product standards for specific acceptance criteria, OD/thickness ranges, and weld positioning requirements.
This guidance highlights the practical value of the ISO 8492 flattening test for ensuring tube integrity, manufacturing quality and compliance with international tube testing practices.
