FOREWORD The American National Standards Committee EM was organized in June 1920, and it developed the American Standard ASA B4a-1925, Tolerances, Allowances and Gages for Metal Fits. As a result of committee work during World War I1 by ASA and ABC (American, British, Canadian), American Standard, Limits and Fits for Engineering and Manufacturing(PartI), ASA B4.1-1947, was produced. The preface to that document made significant reference to the contribution of the ABC meetings in developing agreement on five basic principles, four of w h c h apply to the present standard. These related to the desirability of establishing common definitions, a table of preferred basic sizes, a system of preferred tolerances and allowances, and a uniform method of applying tolerances. In 1973, the General Motors Corporation recognized a need for a metric standard similar to the IS0 R286 and published an interim standard which was later adopted as an ANSI Special Metric Publication, SR 11. The EM Standards Committee was reorganized in November 1975, and renamed “Standardization of Allowances and Tolerances for Manufactured Parts”. The first draft proposal of this standard was based on the principles noted above and utilized computer programs to implement the concept. The preferred basic sizes have been selected from the American National Standard for Preferred Metric Sizes for Round, Square and Hexagonal Metal Products, B32.4-1974, and the first choice sizes are all consistently rounded off from the Renard 10 (R10) series of preferred numbers. A logical reduction or expansion of the first choice sizes can simply be achieved by utilizing the RS or R20 series of preferred numbers as explained in this standard. The selection of standardtolerance zones and preferred metric fitsin this standard were based on international and national standards shown in the following list: ~

AS 1654
The above standards have affected the availability of material stock, tooling and gages to the preferred IS0 tolerances throughout the world. Implementation of this standard by industry can greatly reduce cost in manufacturing. A draft proposal was circulated for letter ballot of the B4 Committee on October 16, 1976. Comments received as a result of this ballot led to changes and subsequent approval of the text by the Committee. Finalapproval for t h i s standard was granted bythe American NationalStandardsInstitute (ANSI) on 8 March 1978.
ACKNOWLEDGMENT Tables 2, 3, 4 and 5 of the text and Tables A1 through A24 of the Massey-Ferguson and full rights to usage have been conveyed to ASME.

1. SCOPE
--`,`,`,,,,,``,```,````,`,,,`,-`-`,,`,,`,`,,`---
Thisstandard describes the IS0 system of limits and fits for mating parts as it is approved for general engineering usage in the United States of America. It establishes: (1) the designation symbols used to define specific dimensional limits on drawings, material stock, related tools, gages, etc., (2) the preferred basic sizes (first andsecond choices), (3) the preferred tolerancezones (first, secondand third choices), (4) the preferred limits and fits for sizes (first choice only)upto andincluding 500 millimeters,and (5) definitions of related terms. Tolerance zones for basic sizes in the range from 500 to 3 150 mm are specified in Appendix B.
( I ) Basic Size. The size to which limits or deviations are assigned. The basic sizes is the same for both members of a fit. It is designated by the number 40 in 40H7.
(2) Deviation. The algebraic difference between a size and the corresponding basic size. (3) Upper Deviation. The algebraical difference between the maximum limit of size and the corresponding basic size. (4) Lower Deviation. The algebraic difference between the minimum limit of size and the corresponding basic size.
The general terms “hole” and “shaft” can also be taken as referring to the space containing or contained by two parallel faces of any part, such as the width of a slot, the thickness of a key, etc.
( 5 ) Fundamental Deviation. That one of the two deviations closest to the basic size. It is designated by the letter H in 40H7.
2. DEFINITIONS
( 6 ) Tolerance. Thedifference between themaximum and minimum size limits on a part.

The first choice sizes can be rationalized by selecting every second number in the series such as 1 , 1.6, 2.5, 4, 6, 10. 16, etc.,andthisnumber series is rounded off from the RS series of preferred numbers (60% increments).
Deviationsfrom basicsize for all tolerancezones in Figures 2 and 3 aretabulated insizesover 0 to 500 mm in Appendix A. Deviationsfrom basicsize for all tolerancezones not shown in Figure 2 and Figure 3 may be calculated from table values given in Appendix B for sizes up to 31 50 mm.
Preferred sizes outside the range of 1 through 1000 are found by multiplying or dividing the sizes shown in Table 1 by 1000 or multiples thereof. Table 1 Preferred Sizes Basic Size, mm

7. PREFERRED FITS
First choice tolerance zones are used t o establish preferredfits in thisstandard,asshownto relative scale inFigure 4 forholebasisand in Figure 5 for shaft basis fits.Hole basis fits have afundamental deviation of “H”on the hole, and shaftbasis fits have a fundamental deviation of “h” on the shaft. A description of both types of fits which have the same relative fit condition is givenin Figure 6. Normally, the hole basis system is preferred, however, when a commonshaftmateswith several holes,theshaft basis system should be used. Thus, clearance fit H7/h6 is included in both hole basis and shaft basis fits.

The hole basis and shaft basis fits of Figure 6 are combined with the first choicesizes of Table 1 to form Tables 2 , 3 , 4 and 5 where the specific limits as well as the resultant fits are tabulated.

If the required size is not tabulated in Tables 2 , 3 , 4 and 5, thepreferredfitcanbecalculatedfromnumericalvalues shown in TablesA1through A24 in Appendix A.

It is anticipated that other fit conditions may be necessary t o suit,special requirements, and a preferred fit can be loosened or tightened simply by selecting a standardtolerancezone in Figure 2 or 3 . Otherfit conditionsmaybecalculatedfromthenumerical values for standard tolerance zones shown in Tables AI through A24 in Appendix A.

6. PREFERRED TOLERANCE ZONES
The preferred tolerance zones are shown in Figure 2 for internal dimensions and in Figure 3 for external dimensions. The encircled tolerance zones ( I 3 each) are first choice, the framed tolerance zones are second choice, and the open tolerance zones are third choice. Theencircledtolerancezonesarespecifiedfor all preferred fits in this standard. --`,`,`,,,,,``,```,````,`,,,`,-`-`,,`,,`,`,,`---

APPENDIX
B
B1. INTRODUCTION
This appendix provides the data necded to calculate limit dimensions for nonpreferred tolerance designations (that is those not shown in Figures 2 and 3 of this standard) and for basic sizes larger than 500 millimeters. This appendix contains: a. International tolerance grades from IT01 thru IT16 for basic sizes up to and including 3 I50 millimeters (Table BI). Tolerance zones with IT grades larger than IT16 are sometimes used. A footnote in Table B1 gives a simple formula for calculating IT17, IT18, etc. b. Fundamental dewations for basic sizes up to 3 150 millimeters: B3
Table Holes Table Shafts
B3
c. Interpretation of I S 0 symbols using the table values for basic sizes up to 3150 millimeters (paragraph B2).
d . Formulas f o r the derivation of table values. These formulas are for reference only. Rounding variationsintroduced in calculationsmayresult in values whichareinconsistentwiththe published national and international standards (paragraph B3). e. Guidelines for convertingfits (paragraph B4).

83 DERIVATION OF TABLE VALUES This section explains how the numerlcal values shown in Tables 8 1 . I32 and 83 were derived
B3.1 INTERNATIONAL TOLERANCE GRADES (IT)
Table BI of International Tolerance Grades lists values based on former national standards. Formulas have been empirically determined to meet these values. Eighteen International Tolerance Grades are provided in this standard, and are designated ITOl, IT0 and IT1 through IT16. The lower numerical grade number, the more precision or closer tolerance of manufacture is required. The numerical values of these tolerance grades are given in Table BI . Determination of the steps of the more commonly used grades of IT6 through IT16 is based on the Renard R5 geometric series as shownin Table B4. TABLE B4 Formulas for IT Grades 6 Through 16' 10i*

where i and D are in millimeters. The diameter D is considered as the geometrical mean of the maximum and minimum diameters of each step D = maximum diameter) x (minimum diameter). For the whole of the step up to 3 millimeters, the diameter is considered as the geometrical mean of 1 and 3 mm. Grades IT01 through ITS are used for high precision and are calculated by a different method as shown in Table B5.
93.2 DERIVATION OF FUNDAMENTAL DEVIATIONS FOR SHAFTS
The fundamental deviation has been previously defined as that one of 1wo deviations closest to the basic size. Table B3 lists these values for shafts. This table has been developed based’on experimental data and cannot in every case be totally calculated. Formulas have been derived, however, irotn the table values to fit most cases. The general formula is as follows: Fundamental Deviarion =
(Y
t
OD’
-
1000
where a, 0, and y are determined frcm Table B6 and D represents the geometric mean diameter of the particular step in mdlimeters. As noted in the table there are several exceptions to the general formula. The fundamental deviation for shafts designated “a” through “h” is the upper deviation. The lower deviation is found by subtracting the numerical value of the IT grade from the fundamental deviation. The fundamental deviation for shafts designated “j” through “zc” is the lower deviation. The upper deviation is found by adding the numerical value of the IT grade to the fundamental deviation.

63.3 DERIVATION OF FUNDAMENTAL DEVIATIONS FOR HOLES The fundamental deviations for holes are based on the fundamental deviations for shafts. The relationship varies with both fundamental deviation letter and 1T grade. The general rule for determining the fundamental deviation of a hole is as follows: For fundamental deviations A through H , the lower deviation for holes equal minus the upper deviation for shafts and for fundamental deviations J through ZC the upper deviation for holes equals minus the lowerdeviation for shafts. This is shown pictorially in Figure B1. D = Hole deviation

There are several exceptions to the general rule. The reasons for these exceptions must be maintained in order to keep the tables consistent withIS0 standards. The exceptions to the general rule are as follows: 1. For holes N for IT grades 9 through 16 above 3 mm, the fundamental deviation = 0.000 2. For holes J , K,M and N up to IT grade 8 inclusive and P through ZC up to IT grade 7 inclusive above 3 mm, the fundamental deviation is calculated as follows: The upper deviation of the hole equals minus the lower deviation of the shaft plus the difference between the tolerance of the gradein question and that of the next finer grade. Upper Deviation (hole) = -lower deviation (shaft) t A Where A = IT, - IT, - I = IT (shaft) -- IT (next finer shaft) Using a hole 60 P7 as an example, the calculationis as follows: -0.037 t (0.030 -- 0.019) = -0.021 or 59.979 (Max. hole size) (Table 83) t (Table B1 grade 7 - grade 6) = (Table B2) (Table 5)

B4. CONVERSION OF FITS
It may sometimes be necessary or desirable to modify the tolerance zone on oneor both of two mating parts, yet still keep the total tolerance and fit condition the same. Examples of this appear in Figure 6 of ANSI B4.2 when converting from a hole basis fit to a shaft basis fit. The corresponding fits are identical yet the individual tolerance zones are different. The rule for converting from one type of fit to another can be simply stated as, “Reverse the fundamental deviations between the shaft and hole keeping the IT grade the same on each individual part.” Two examples of this are shown below. Each of the examples represent a preferred fit from Figure 6 of ANSI B4.2 and are for a 60 millimeter basic size. EXAMPLE 9. FIT 6 0 H l l / c l l CONVERTED TO 6 O C l l / h l l

APPENDIX C APPLICATIONS
Many factors, such as length of engagement, bearing load, speed, lubrication, operating temperature, humidity, surface texture, and materials, must be taken into consideration in the selection of fits for a particular application. Choice of other than the preferred fits might be considered necessary to satisfy extreme conditions. Subsequent adjustments might also be desired as the result of experience in a particular application to suit critical functional requirements or to permit optimum manufacturing economy. Selection of departure from these'recommendations will dependuponconsideration of the engineering andeconomicfactors that might be involved, however, the benefits derived from use of preferred fits should not be overlooked.
To indicate the machining processes which may normally be expected to produce work withinthe tolerances indicated by the IT tolerance grades given in this standard, Figure C1 has been provided. This information is intended merely as a guide in selecting suitable processes for a particular IT tolerance grade. Practical usage of the various IT tolerance grades is shown in Figure C2.

APPENDIX D REFERENCE TEMPERATURE
The standard reference temperature for industrial length measurements is 20 degrees Celsius. For other temperatures, particularly. when the gage is made from another type of material than the part to be inspected corrections should be made in accordance with the difference in thermal expansion’* for the two parts. Example:
Measure a hole in an aluminum die casting with a steel gage at the room temperature 30 OC. Temperature correction
