ISO 3827-1:1977 pdf download. Shipbuilding — Co-ordination of dimensions in ships’ accommodation — Part 1: Principles of dimensional co-ordination.
The rationalization of traditional shipbuilding methods and the increasing use of prefabricated assemblies necessitates the utilization of standardized components wherever possible. In the outfitting of ships, in order to achieve the maximum benefit from the use of these components a systematic design method, applying both to the components and the space within which they are used must be adopted which will give a common basis for layout, production and assembly.
Dimensional co-ordination is a system of applying a range of related dimensions to the sizing of components and assemblies and the structures incorporating them. This method of standardizing sizes or dimensions, which are not necessarily related to particular components, mater ials or manufacturing processes, permits its application to the widest possible range of components and assemblies, and will give the following advantages:
1) the maximum economy in the production of components by variety reduction:
2) the reduction in manufacture of non-standard units;
3) the avoidance of wastage in cutting components on site by achieving maximum flexibility in assembly;
The advantages of dimensional and modular co-ordination have been internationally recongized for many years and an International Standard has been agreed for the incre ments or modules to be used in the construction industry.
The ultimate aim in publishing recommendations fo dimensional co-ordination is the establishment of standard ized ranges of sizes for components, and in order to achieve the maximum utilization of these components it is necessary to establish a comprehensive system which will form a framework for sizing, positioning and assemblin co-ordinated components.
In shipbuilding the main advantages in utilizing co-ordinated components occur in the accommodation areas where repetitive components are used which are common to the other industries operating dimensional co-ord ination.
1 SCOPE AND FIELD OF APPLICATION
This International Standard sets out the basic principles of dimensional co-ordination, with particular reterence to the co-ordination of dimensions in ships accommodation.ISO 3827-1:1977 pdf download.
