23、he cone proof load test. 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the editions indicated were valid. All stan- dards are subject to revision, and Partie
24、s to agreements based on this International Standard are encouraged to investigate the possibility of ap- plying the most recent editions of the Standards in- dicated below.

25、 fasteners - Part 2: Nuts with specified proof Load values - Coarse thread. ISO 898-6: 1988, Mechanical properties of fasfeners - Part 6: Nuts with specified proof load values - Fine pitch thread. 3 Principle Detection of the presence of seams or Cracks which could be detrimental. The use of a conic
26、al washer exaggerates the influence of such defects on the load-bearing ability of the nut by introducing a si- multaneous dilating and stripping action. 4 Apparatus 4.1 Conical washer (see figure 1), having a mini- mum hardness of 57 HRC. The contact Point of the cone shall be flat and shall have a
27、 width of 0,13 mm + 0,03 mm for nominal thread diameters n 12 mm.- Dimensions in millimetres surface roughness in micrometres + 0,05 r Nominal diameter of mandrel 0 - Contact polnt Figure 1 - Conical washer 4.2 Mandrel, hardened (45 HRC min.) and threaded to tolerante class 6g, except that the toler
28、ante of the major diameter shall be the last quarter of the 6g range on the minimum material side. 1) To be published. (Revision of ISO 898-23980) ENISO10485:20045 Procedure Assemble the nut and conical washer on the mandrel as shown in figure2. The conical washer shall bear against a nut face which
29、 is flat and normal to the nut axis. Apply the specified cone proof load (see clause 6) to the nut. The Speed of testing, as determined with a free- running Cross-head, shall not exceed 3 mm/min. The cone proof load shall be retained for 10 s. 6 Criteria The nut shall support the proof load specifie
