Errata,to,ASME Bl.15-1995,Unified Inch Screw Threads,(UNJ Thread Form),The Errata corrections listed below and appearing herein apply to ASME B1.15-1995, Unified,Inch Screw Threads (UNJ Thread Form). Corrections are incorporated directly into the affected,pages and are indicated by a margin note, (E). The pages show the corrections given below.,The pages not listed are the reverse sides of the listed pages and contain no changes.,Page Location Change,1 1.1 In fourth line, 0.600 changed to 0.060,4 Fig. 2 (I) D1 max. changed to D2 max.,(2) Dl min. = D2 bsc changed to D2 min. = 0 2 bsc,(3) TD1/2 changed to TD2/2,5 Fig. 3 ( I ) d , max. = dl bsc changed to-dl rnax. = d2 bsc,(2) dl min. changed to d2 min.,(3) TdJ2 changed to Td2/2,(4) In General Note, “(See para. 5.3)” changed to read:,“(See para. 2.3)”,9,10,11,51,Fig. 4,4.1,4.3,4.4.2(b),4.4.2(c),A2,Sentence added to Note (1) reading: “X equal or greater,than 0.150 1 P1. ’’,In fourth line. “length” changed to read: “lengths”,In second line, delete (T),In second Example, fourth line, Lead tolerance of 0.009,in. changed to 0.0009 in.,In Example, fourth line, 0.009 changed to 0.0009,Under MINOR DIAMETER:,(1) “dl basic minor diameter“ changed to “dl bsc basic,( 2 ) “d; maximum minor diameter” changed to “dl max,minor diameter”,maximum minor diameter”,MARCH 1997,THE AMERICAN SOCIETY OF MECHANICAL ENGINEERS,345 East 47th Street, New York, NY 10017 N0131E,COPYRIGHT American Society of Mechanical Engineers,Licensed by Information Handling Services,~,STD-ASME BI-15-ENGL L775 = 0757b70 058U42b 757,ASME 61.15-1995,UNIFIED INCH SCREW THREADS (UNJ THREAD FORM),SECTION 1 GENERAL,(E) 1.1 Scope,This Standard establishes' the basic triangular profile,for the UNJ thread form, provides a system of,designations, lists the standard series of diameterpitch,combinations for diameters from 0.060 to 6.000,in., and specifies limiting dimensions and tolerances.,It specifies the characteristics of the UNJi nch series,of threads having 0.1501 1P to0 .18042P designed radius,at the rooto f the external thread, anda lso having,the minor diameter of the external and internal threads,increased above the ASME B1.1 UN and UNR thread,forms to accommodate the external thread maximum,root radius.,1.2 Field of Application,The UNJ screw thread is designed for aerospace,inch threaded parts, or four se on other highly stressed,applications requiring high fatigue strength. For aerospace,applications, only Classes 3A and 3B should be,used.,1.3 Assembly,Threads conforming to the UN profile (ASME B1.1),and the UNJ profile are not interchangeable because,of possible interference between the UNJ external,thread minor diameter and the UN internal thread,minor diameter. However, the UNJ internal thread,will assemble with the UN external thread.,1.4 Federal Government Use,When this Standard is approved by the Department,of Defense and federal agencies and is incorporated,into FED-STD-H28/4, Screw Thread Standards for,Federal Services, Section 4, the use of this Standard,by the federal government is subject to all the requirements,and limitations of FED-STD-H28/4.,1.5 References,The latest issues of the following documents form,a part of this Standard to the extent specified herein.,American National Standards,ASME B1.1 , Unified Inch Screw Threads (UN and,ASME B1.3M, Screw Thread Gaging Systems for,ANWASME B1.7M, Nomenclature, Definitions,ASME B1.23l, Gages and Gaging for Unified Inch,ASME B1.30M, Screw Threads - Standard Prac-,UNR Thread Form),Dimensional Acceptability,and Letter Symbols for Screw Threads,J Series Screw Threads,tice for Calculating and Rounding Dimensions,'Proposed ASME Standard under development by The American,Society of Mechanical Engineers.,1,COPYRIGHT American Society of Mechanical Engineers,Licensed by Information Handling Services,UNIFIED INCH SCREW THREADS,(UNJ THREAD FORM),SECTION 2 PROFILE OF THREAD,ASME 61.15-1995,Bas 2ic.1 Profile ftlhane f kosr upper limit profile.
