ASME B32.100:2016 pdf free download.Preferred Metric Sizes for Flat, Round,Square, Rectangular,and Hexagonal Metal Products.
SME B32.100 is in no way meant to preclude the use ofsuch sizes where they are required. However, for general purpose applications or where requirements permit some latitude in the selection of thickness or thick. ness/width/length combinations, the simplified preferred sizes given in this Standard should facilitate interchangeability of metals in design, reduce inventories, and Increase the availability of warehouse stocks of those sizes commonly used for general purpose applications. In such instances, the use olsizes listed in this Standard is to be encouraged.
All of the sizes included in this Standard are not necessarily produced in all metals and grades. Producers or distributors should be consulted to determine availability of a particular thickness or thickness/width combination for a given metal product.
3 USE OF TABLES
Wherever possible, sizes should be selected from the columns headed “First Choice.” Only if no size in the preferred list is suitable should a selection be made from the columns headed “Second Choice” or “Third Choice.” Lengths should be selected from the preferred list.
4 BASIS OF TABLES
The sizes in this Standard are derived from a list of preferred metric sizes in which each number is approximately 60% greater than the number preceding it IANSI B4.2 (Preferred Metric Limits and Fits) or ISO 497 (Guide to the choice of series of preferred numbers and series containing more rounded values of preferred numbers) Series R5’]. Second Choice sizes are in increments of 25% (Series Rio’) and Third Choice sizes in increments of 12% (Series R20’). Some deviations from this principle occur as the result of minor rounding. The selected sizes also reflect standard material sizes in ISO and national standards in traditional metric countries.
5 TOLERANCES
Material product tolerances are shown in applicable international or national product standards. Normal tolerances shown in international standards are generally larger and could be up to twice as large for metric material compared with customary inch tolerances used in the U.S. Only a few major product groups will be covered by this Standard, and they are specified in paras. 5.1 through 5.8.
