NOTE 2 If necessary, the code I9005 shall be placed between the description block and the identity block. NOTE 3 Parts manufactured before the issue of this standard shall be accepted without technology code.In addition to the manufacturer’s own marking, each bush and its package shall be marked with the identity block specified in clause 4 of this standard. The technology used by the manufacturer shall be stated within the identity block. Marking position and method are at manufacturer’s option and shall not have any detrimental effect on the bush. Bushes which are too small to be marked with the full information required shall have this on the package only.BS EN 2288 pdf download.
