European Standard EN 29692: 1993 has the Status of a DIN Standard.
National foreword This Standard has been has been published in accordance with a decision taken byCEN/BT to adopt, without alteration, International Standard ISO 9692 as a European Standard. The responsible German body involved in its preparation was the Normenausschuß Schweißtechnik (Welding Standards Committee). The dirnensionsand the dimensionalranges givenin this Standard are basedon experience.In Order to make the scopeas comprehensive as possible, wide tolerances have been specified for angles, gaps and root face thickness. The joint type shall be selected as a function of the materials employed, the welding Position and the welding process, to the subject weld being fully penetrated. This requires the selection of appropriate welding Parameters and, if necessary, root machining in the case of double-sided welding. The symbols for joint types are intended to facilitate comrnunication.If necessary, the designation may be completed by an additional indication of the requireddimensions.

Foreword In 1992, CEN/BT decided to subrnit International Standard
ISO 9692 : 1992 Metal-arc welding with covered electrode, gas-shielded rnetal-arc welding and gas welding; joint preparations for steel to the Unique Acceptance Procedure in accordance with resolution BTS 2 C48/1992. The result was positive. This European Standard shall be given the Status of a national Standard, either by publication of an identical text or by endorsernent, and conflicting national Standards withdrawn, by August 1994 at the latest. In accordance with the CENKENELEC Internat Regulations, the following countries are bound to irnplernent this European Standard: Austria, Belgiurn, Denrnark,Finland, France, Gerrnany, Greece, Iceland,Ireland,Italy,Luxembourg,Netherlands, Portugal, Spain, Sweden, Switzerland and United Kingdom.

Endorsement notice The text of theInternational Standard ISO 9692 : 1992 was approved byCEN as a European Standard without any rnodification. NOTE: Normative references to international publications are listed in annex ZA (normative).
lntroduction ThisInternationalStandarddefinestheParameterscharacterizingthe jointpreparationandthecollection of well-experiencedvaluesand shapes representing more design limits than manufacturing limits. comThe requirements given in this International Standard have been piled on the basis of experience, and contain dimensions for types of joint preparation that are generally found to providesuitablewelding conditions. However, the extended field of application makes it necessary to give a range of dimensions. The dimension ranges specified represent design limits and are not tolerances for manufacturing purposes. Manufacturitlg limits depend, for instance, on welding process, parent metal, welding Position, quality level, etc. Therefore, the requirements given are more a recommendation than a specification. Because of the conimon character of this International Standard, the examples given cannot be regarded as the only Solution for the selection of a joint type.
Specificfields of applicationandmanufacturingrequiretnents(e.g. Pipeline construction) may be covered by selected ranges specified other Standards adapted from this basic International Standard.

This International Standard pertains to types of joint preparation for metal-arc welding with covered electrode.gas-shieldedmetal-arcweldinyandgas welding on steel (See clauses 3 and 4). It applies lo jointpreparation for fully-penetrated butt welds, except in the case of some recornrnendedtypes of jointpreparation(reference numbers 3 10A. 3.106 and 4.10.10Cj: if a butt weld is notpossibleornecessary. Special arrangenients need to be made. For not-fully-penetraled butt welds.typesofjointpreparationanddimensions differingfromthosespecifiedinthisIniernational Standard may be stipulated.
