Aerospace. Self-locking nuts with maximum operating temperature greater than 425 degrees C. Test methods. | Status: Superseded, Withdrawn

1 Scope This International Standard specifies test methods for metric self-locking nuts with MJ threads intended for use in aerospace construction at maximum operating temperature greater than 425 °C. It describes the test device and the method for each test. It applies to self-locking nuts as defined above, provided that the relevant documents (dimensional standard, drawing, procurement specification, etc.) refer to this International Standard. Other test devices or test methods than those specified in this International Standard may be used, but, in the event of a dispute, the requirements laid down in this International Standard shall take precedence. This International Standard shall be used in conjunction with ISO 8641.
