Hot dip galvanizing of irregularly shaped articles

.1

This Standard specifies the requirements for zinc coating (galvanizing) by the hot-dipping process on iron and steel products intended or primarily for use in electrical and communication systems, made from rolled, pressed, cast iron, or forged shapes such as structural sections, plates, bars, pipes, or sheets 1 mm thick and thicker.

1.2

This Standard applies to

a) both unfabricated and fabricated products such as assembled steel products, structural steel fabrications, large hollow sections bent or welded before galvanizing, and wire work fabricated from uncoated steel wire; and

b) steel forgings and iron castings that are to be galvanized separately or in batches.

1.3

This Standard does not apply to

a) the continuous galvanizing of chain link fence fabric, wire, sheet, and strip; and

b) pipe and conduit that are normally hot dip galvanized by a continuous or semi-continuous automatic process.

1.4

In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
