This part of ISO 9692 contains the parameters characterizing the joint preparation and the collection of frequently recurring values and shapes. The specifications given in this part of ISO 9692 have been compiled on the basis of experience and contain dimensions for types of joint preparation that are generally found to lead to suitable welding 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. Manufacturing limits depend, for instance, on welding process, parent metal, welding position, and quality level, etcetera. Because of the common character of this part of ISO 9692, the examples given cannot be regarded as the only solution for the selection of a joint type. Specific fields of application and manufacturing requirements (for example pipeline construction) may be covered by selected ranges specified in other standards adapted from this basic part of ISO 9692. The committee responsible for this standard is NA 092-00-06 AA "Darstellung und Begriffe (DVS AG I 4)" ("Representation and terms") at DIN.
