Wedge socket assemblies for noncircular elastomeric-coated steel suspension members shall conform to 2.20.9.2, 2.20.9.3, and 2.20.9.9.1 through 2.20.9.9.5.
2.20.9.9.1
A test specimen consisting of the strongest noncircular elastomeric-coated steel suspension member for given noncircular elastomeric-coated steel suspension member dimensions and wedge socket assembly shall be subjected to a destructive tensile engineering test. The noncircular elastomeric-coated steel suspension member socket shall develop at least 80% of the manufacturer's minimum breaking force of the strongest noncircular elastomeric-coated steel suspension member to be used in such a fastening without the noncircular elastomeric-coated steel suspension member slipping through the assembly.
2.20.9.9.2
Wedge noncircular elastomeric-coated steel suspension member socket assemblies shall be of such a strength that when tested as in 2.20.9.9.1, the noncircular elastomeric-coated steel suspension member shall break before the socket or wedge is materially deformed.
2.20.9.9.3
Suppliers of noncircular elastomeric-coated steel suspension member wedge sockets shall submit certification showing that the sockets, with visible permanent manufacturer's identification, have successfully passed the tests described in 2.20.9.9.1 and 2.20.9.9.2 at a testing laboratory.
2.20.9.9.4
When the noncircular elastomeric-coated steel suspension member has been seated in the wedge socket by the load on the noncircular elastomeric-coated steel suspension member, the wedge shall be visible and the end of the noncircular elastomeric-coated steel suspension member shall be prevented from slipping in the socket should the load on the noncircular elastomeric-coated steel suspension member be removed for any reason.
2.20.9.9.5
Markings on the wedge socket assembly components shall be as follows:
(a) Each socket shall be permanently and legibly marked or color coded to identify the noncircular elastomeric-coated steel suspension member size to be used in the assembly. The markings shall be visible after installation.
(b) Each wedge shall be permanently and legibly marked or color coded to identify the corresponding socket or sockets and noncircular elastomeric-coated steel suspension member size within which it is to be inserted to form an assembly. The markings shall be visible after installation.
