ISO 17652-1:2003 specifies standardized conditions for an assessment of shop primers on the weldability of steel materials. It is intended to be used for assessment of shop primers by testing by:
the suppliers during development of new shop primers;
testing by the suppliers during production as part of a quality control scheme;
declaration of the properties of shop primers by suppliers;
use as a reference in contracts between suppliers and customers for deliveries of shop primers;
acceptance testing of shop primers by customers.
This part of ISO 17652 can also be used for comparisons between different shop primers using the welding procedure appropriate for the task, or between the different welding procedures using a specific shop primer.
