This is an abridgement of part of a dissertation presented by the Author and M. Beyrodt at Wilhelm-Pieck University, Rostock, in 1978. Reasonable limits to the unavoidable geometrical deviations of structural parts, assemblies, and sections are necessary for the further rationalisation of hull construction and for meeting the increasingly high standards of quality required. In East Germany, as elsewhere, increased effort is of regulations on tolerances. The Author explains the methodology of determining such tolerances, and discusses the various considerations involved, under the headings:--1. Objective of Establishing Tolerances (1.1--Satisfying the functional requirements; 1.2--Tolerance and production deviations). 2. Relating the Tolerances to the Geometrical Characteristics. 3. Consideration of Uncertainties in the Measurements that are Made. 4. Type of Determination of Tolerances (i.e., determination on a basis of theory or of experience), and Scope of Tolerances. In his concluding remarks, the Author mentions that, in shipbuilding production, only a portion of the permissible deviations can as yet have an accurate theoretical or experimental basis, represent the technologically attainable optimum, and ensure that no rectification will be needed later during production. However, tolerances are important for the whole range of shipyard production, and the necesary extension of tolerance regulations and standards, and their embodiment in shipyard quality-control systems, can only take place gradually and by direct co-operation between the parties concerned. Order from BSRA as No. 52,309.
