The proof load shall be applied byscrewing the eyebolt to the full thread engagement into a blocksecured in one jaw of the testing machine and
22、 held to the otherjaw by means of a mandrel passing through the eye. The roundmandrel shall have a diameter equal to one half of the insidediameter of the eye. The proof load shall be applied at amaximum cross head speed of 0.12 in. per minute, held for 10s. and then released. Permanent deformation
