BS 84:2007 惠氏螺纹牙样的平行螺纹.要求

This British Standard specifies limits of sizes, and tolerances, for single start parallel screw threads of Whitworth form, for general engineering use. It is not applicable to threads for threaded pipe joints, screw threads associated with interference fits, such as those on the “metal ends” of studs and in the corresponding tapped holes, or to screw threads which are to be subjected to high temperatures. This standard specifies the following thread series: a) a coarse thread series, the British Standard Whitworth (B.S.W.) series, with nominal diameters in the range in to 6 in. b) a fine thread series, the British Standard fine (B.S.F.) series, with nominal diameters in the range in to 4 in. NOTE The tables of limits and tolerances for the B.S.F. series extend up to the 3 in size only, since nominal sizes above 3 in are rarely used. c) a supplementary selected thread (WHIT. S.) series with nominal diameters from in to 7 in. d) a truncated Whitworth form series (specified in Annex A). This British Standard specifies limits of sizes, and tolerances, of uncoated threads and also for metal coated threads (including threads coated with nickel, tin or zinc) with a thickness of coating of the order of 0.000 2 in. It is not applicable to heavily coated threads (i.e. threads with a coating thickness above 0.000 35 in). NOTE Supplementary information is given in Annex B, Annex C and Annex D.

ASME B1.1-2003 统一标准英制螺纹(UN和UNR螺纹牙型)

This Standard specifies the thread form, series, class,allowance, tolerance, and designation for unified screwthreads. (In order to emphasize that unified screwthreads are based on inch modules, they may be denotedunified inch screw threads.) Several variations in threadform have been developed for unified threads; however,this Standard covers only UN and UNR thread forms.For easy reference, a metric translation of this Standardhas been incorporated as Nonmandatory AppendixC. Nonmandatory Appendices A through E containuseful information that is supplementary to the sectionsof this Standard.

JIS B 0255:1998 统一螺纹极限量规

この規格は，JIS B 0210及びJTS B 0212に規定するユニファイねじの寸法検査に用いる限界ゲージ(以下，ねじ用限界ゲージという。)及びその点検に用いるゲージ（以下，点検用ゲージという。)について規定する。なお，ねじ用限界ゲージ，点検用ゲージを総称して単にゲージという。他の検査方法，例えば，指示計器による測定を用いてもよいが，この規格によるゲージを用いて検査する。この規格は，許容限界内を満足している工作物ねじと他のものとを区別する手段を規定することを目的とする。工作物ねじの互換性を確保し，生産者と使用者との間の争いを避けるために，次の原則を適用する。a)生産者は，実際のねじ寸法(例えば，単独有効径及び総合有効径)が規定限界外にあるいかなる工作物ねじも出荷しない。b)使用者は，実際のねじ寸法(例えば，単独有効径及び総合有効径)が規定限界内にあるいかなる工作物ねじも拒否しなしい。このニつの原則を満たすために，この規格は，ねじの検査に必要なゲージの種類及び寸法，並びにこれらのゲージを使用する条件及び工作物ねじの検査について規定する。

ASME B1.15 ERTA-1997 统一英制螺纹(UNJ螺纹形式)

This Standard establishes the basic triangular profile for the UNJ thread form, provides a system of designations, lists the standard series of diameter-pitch combinations for diameters from 0.600 to 6.000 in, and specifics limiting dimensions and tolerances. It specifies the characteristics of the UNJ inch series of threads having 0.15011P to 0.18042P designed radius at the root of the external thread, and also having the minor diameter of the external and internal threads forms to accommodate the external thread maximum root radius. root radius.
