1.2 This specification makes use of both U.S. Customary Units and the International System of Units (SI). The measure-ments are not exact equivalents; therefore, each system must be used independently of the other without combining in any way when referring to weld metal properties. The specification with the designation A5.0IM uses SI Units. The spec-ification A5.0l uses U.S. Customary Units. The latter are shown within brackets [ ] or in appropriate columns in tables and figures. The standard dimensions based on either system may be used for the sizing of electrodes, packaging, or both under A5.0IM or A5.01 specifications.

For dated references, subsequent amendments to, or revisions of, any of these publications do not apply.However, parties to agreements based on this Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest editions of the normative documents referred to apply. Members of ISO and IEC maintain registers of currently valid International Standards.
3. Terms and Definitions
In production, the components of welding or brazing consumables shall be divided into discrete quantities so that satis-factory tests with a sample from that quantity will establish that the entire quantity meets specification requirements.These quantities, known by such terms as heats, lots, blends, batches and mixes, vary in size according to the manufac-turer. For identification purposes, each manufacturer assigns a unique designation to each quantity. This designation usu-ally consists of a series of numbers or letters, or combinations thereof, which will enable the manufacturer to determine the date and time (or shift) of manufacture, the raw materials used, and the details of the procedures used in producing the welding or brazing consumable. This designation stays with the welding or brazing consumable and can be used to identify the material later, in those cases in which identification is necessary.
3.1 Dry Batch. The quantity of dry ingredients mixed at one time in one mixing vessel.
NOTE: Liquid(s), such as binders, when added to a dry batch, produce a wet mix. A dry batch may be divided into homogeneous smaller quantities, in which case addition of the liquid(s) produces a corresponding number of smaller wet mixes.
3.2 Dry Blend. Two or more dry batches from which quantities of each are combined proportionately, then mixed in a mixing vessel to produce a larger quantity in which the ingredients are as uniformly dispersed as they would have been had the entire quantity been mixed together at one time in one large mixer.
NOTE: A dry blend, as in the case of a dry batch, may be used singly or divided into smaller quantities, in which case addition of liquid(s) produces a corresponding number of smaller wet mixes.AWS A5.01M A5.01 pdf download.
