ISO 7437:1990 defines general rules for executing production drawings for prefabricated structural components, focusing on what such drawings must specify for manufacture, inspection, and further handling. It covers the scope of required documentation content, designation practices, representation of views and sections, dimensioning conventions, and how to indicate special information such as reinforcements, surface finish boundaries, and built-in parts. It also links drawing execution to relevant ISO standards and specifies preferred sheet sizes and scales.

FAQs

What is the scope of ISO 7437:1990?

It establishes general rules for the execution of production drawings for prefabricated structural components, addressing the information needed for manufacture, inspection, and further handling.

What general rules apply to the production drawings?

The drawings must define shape and composition, be fully dimensioned, follow relevant international standards, and use preferred sheet sizes and scales as specified.

How should surface finish requirements be shown?

The boundary of surfaces requiring special treatment must be indicated on the drawing using a thick chain line, with reference to the specification where needed.
