Themetallic-coated fabric may be polymer coated after fabrication.1.2 Welded wire mesh fence fabric is produced
4、 in four types, based on the kind of coating, as described in Section 4.1.3 This specification is applicable to orders in either inch-pound units or SI units. Values stated in either inch-pound or SI unitsare to be regarded separately as the standard. Within the text, the SI units are shown in brack
5、ets. The values in the two systemsare not exact equivalents; therefore, each system shall be used independent of the other, without combining values in any way.1.4 This specification references notes and footnotes, which provide explanatory material. These notes and footnotes (excludingthose in tabl
6、es and figures) shall not be considered as requirements of this specification.1.5 The following safety hazards caveat pertains only to the test methods portion, Section 13, of this specification: This standarddoes not purport to address all of the safety concerns, if any associated with its use.
