6、ardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right

7、to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures u

In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules

14、Pa (at ambient temperature )/235 C, 1 100 MPa (at ambient temperature )/315 C and 1 100 MPa (at ambient temperature)/425 C Dimensions 1 Scope This International Standard specifies the dimensions of self-locking, floating, two lug anchor nuts, with counterbore, with MJ threads, of classifications: 1

15、100 MPa/235 C, 1 100 MPa/315 C and 1 100 MPa/425 C. NOTE 1 1 100 MPa corresponds to the minimum tensile stress which the nut is able to withstand at ambient temperature without breaking or cracking when tested with a bolt of a higher strength class. NOTE 2 235 C, 315 C and 425 C corresponds to the m

16、aximum temperature that the nut is able to withstand without permanent alteration to its original characteristics, after ambient temperature has been restored. The maximum temperature is conditioned by the surface treatment. This International Standard is only applicable for the compilation of aeros
