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 to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with IsO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the Iso Council. They are approved in accordance with IsO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 8146 was prepared by Technical Committee ISO/TC 8, Shipbuilding and marine structures. @ International Organization for Standardization, 1985 Printed in Switzerland 5-9ht8 069090 E065 ISO 8146-1985 (E) INTERNATIONAL STANDARD Shipbuilding and marine structures -- Oval eyeplates 1 Scope and field of application 4.2 Nominal size This International Standard lays down the dimensions and The nominal size designation of an oval eyeplate is a numerical materials of oval eyeplates primarily intended for mounting on value without unit for reference and ordering purposes, and is ships' decks and as guy eyeplates on ships' derrick booms for derived from the permissible load in kilonewtons, cargo handling purposes. 5 Materials 2 References Steel according to ISO 630, grade Fe 360 (as minimum quality).
