ISO 2020-1-1997 pdf free download.Aerospace一Preformed flexible steel wire rope for aircraft controls一 Part 1: Dimensions and loads. 6 Ropes 6.1 ConstructIon Wire ropes covered by this part of ISO 2020 are of the two types of construction shown in table 5. 6.1.1 7 x 7 construction This type of wire rope shall be composed of six outer strands each of seven wires laid in a right-hand direction around a steel centre strand of seven wires. The steel centre strand shall be composed of a layer of six wires laid in a right-hand direction around a core or king wire. It shall be of sufficient diameter to give full support to the outer strands. The six outer strands shall be composed of a layer of six wires laid in a left-hand direction around a core or king wire. The lengths of lay shall be as follows: a) the six outer strands shall be laid around the steel centre strand with a length of lay between six and eight times the nominal diameter of the rope; b) the lengths of lay of six wires of the steel centre strand and of the outer strands shall not exceed 60 % of the length…

BS ISO 3209:2016 pdf free.Aerospace Nuts, anchor, self-locking, floating, two lug, with counterbore, with MJ threads, classifications: 1100 MPa (at ambient temperature)/235 00, 1100 MPa (at ambient temperature)/315 °C and 1100 MPa (at ambient temperature)/425 °C Dimensions. This International Standard specifies the dimensions of self-locking, floating, two lug anchor nuts, with counterbore, with MJ threads, of classifications: 1 100 MPa/235 °C, 1 100 MPa/315 °C and 1100 MPa/425 °C. NOTE 1 1100 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 maximum 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 aerospace product standards. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document…
