    Abstract - (Show below) - (Hide below)

    Requirements for patterns, pattern equipment and coreboxes for the production of sand moulds and/or sand cores are specified in this Standard. It does not define equipment for the production of lost patterns, permanent moulds and die casting dies. It also does not define requirements for ancillary items used in the making of pattern equipment (such as dowels, screws, etc).
