This British Standard has been prepared under the direction of the Iron and Steel and the Non-ferrous Metals Standards Policy Committees and is the English language version of EN 10234:1993 Metallic materials — Tube —Drift expanding test, published by the European Committee for Standardization (CEN). No British Standard is superseded.
This standard is based on ISO 8493:1986 Metallic materials — Tube — Drift expanding test which has been editorially changed in the light of the comments received. Minor changes have been made to clause 6 “Test pieces”. The usage of symbols has been aligned with the requirements of ISO 3545-1:1989.
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 150 mm (100 mm for light metals) and thickness not greater than 10 mm. The range of the outside diameter or thickness for which this European Standard is applicable could be more exactly specified in the relevant product standard.
