ISO 15630-2:2019
Steel for the reinforcement and prestressing of concrete — Test methods — Part 2: Welded fabric and lattice girders
This document specifies chemical and mechanical test methods and measurement methods of geometrical characteristics applicable to welded fabric and lattice girders for the reinforcement of concrete.
NOTE In some countries, the expression "welded wire reinforcement" is used in place of "welded (wire) fabric".
For those tests not specified in this document (e.g. bend test, rib/indentation geometry, mass per metre), ISO 15630-1 is applicable.
This document does not cover the sampling conditions that are dealt with in the product standards.
A list of options for agreement between the parties involved is provided in Annex A.
