Phạm vi áp dụng / Scope of standard

This specification covers welded wire reinforcement to be used
for the reinforcement of concrete.

Note 1-Welded wire for concrete reinforcement
has been described by various terms: welded wire fabric (WWF),
fabric, and mesh. The wire reinforcement industry prefers the term
"welded wire reinforcement" or WWR as being more representative of
the range of products being manufactured. Therefore, the term
"welded wire fabric" has been replaced with the term "welded wire
reinforcement" in this specification and in related
specifications. 

This specification is applicable for orders in either SI units
(M 55M) or in inch-pound units (M 55). SI units and inch-pound
units are not necessarily equivalent. Inch-pound units are shown in
brackets in the text for clarity but they are the applicable values
when the material is ordered to M 55. The values stated in each
system are not exact equivalents; therefore, each system must be
used independently of the other. Combining values may result in
nonconformance with the specification.
