This International Standard is a tool for communication between a purchaser and a supplier of welding consumables within quality systems as might, for example, be based upon ISO 9001. This International Standard, together with an ISO or other recognized welding consumable standard, provides a method for preparing those specific details needed for welding consumable procurement which consist of the following: a) the welding consumable classification (selected from the pertinent ISO or other welding consumable standard); b) the lot classification (selected from Clause 5 of this International Standard); c) the testing schedule (selected from Clause 6 of this International Standard). Selection of the specific welding consumable classification, lot classification and testing schedule will depend upon the requirements of the application for which the welding consumable is being procured.
