Copper, copper alloys and aluminium alloys Mechanical properties of non-ferrous metal fasteners Introduction This Japanese Industrial Standard has been made based on IS0 8839 Mechanical properties of fasteners-Bolts, screws, studs and nuts made of non
10、- ferrous metals published in 1986 as the first edition, without changing the technical contents and adding some items not specified in the corresponding International Stan- dard. The revision at this time has been made for the sake of formality as a result of the revision of JIS B 1052 on January 2
11、0, 1998 and the withdrawal of Annex 3 (Nuts for property classes 4T to 12T) to JIS B 1052 on December 31, 2000 followed by the development of a new standard as Annex 2 to JIS B 1181. The parts covered by half tone dot mesh (i-) in this Standard are the matters not specified in the corresponding Inte
12、rnational Standard. i Scope This Japanese Industrial Standard specifies the mechanical properties of bolts (including studs), machine screws and nuts made of non-ferrous metals such as copper, copper alloys and aluminium alloys and conforming to the requirements for application given in Table l(1) a
13、nd the test and inspection methods and the marking of them. Note (1) The bolts, machine screws and nuts made of non-ferrous metals which apply in this Standard are referred to hereafter as “bolts, machine screws and nuts” and a generic term of them as “non-ferrous metal fasteners”. Table 1 Requireme
14、nts for application of non-ferrous metal fasteners Remarks 1 The International Standard corresponding to this Standard is as fol- lows. In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modifie
15、d), and NEQ (not equivalent) ac- cording to ISODEC Guide 21. IS0 8839 : 1986 Mechanical properties of fasteners-Bolts, screws, studs and nuts made of non-ferrous metals (MOD) 2 This Standard which specifies the mechanical properties at ordinary temperature of the non-ferrous metal fasteners for gene
16、ral use does not apply to those with special property requirements such as corro- sion resistance and electrical conductivity.
