10. What are the relevant standards for cable cleats?
IEC 61914 EDITION 2.0, 2015, CABLE CLEATS FOR ELECTRICAL INSTALLATIONS
The international cable cleat standard IEC 61914 provides testing criteria and requires cable cleats to protect the cables during short circuit testing. To comply with the standard, products must pass tests for resistance to flame propagation, impact and ultraviolet light exposure, as well as for lateral retention. The standard includes optional tests for axial retention and resistance to electromechanical forces. The president of Talon Products, Charles Darnell, a Registered Professional Electrical Engineer, IEEE Senior Member and member of ANSI US National Committee of the IEC is the US Representative to the IEC subcommittee responsible for the maintenance of IEC 61914.
NOTE: IEC 61914 Edition 2.0 clarifies that Annex B equations B.5, B.6 and B.7 should not be used to extrapolate short circuit test results.
UL 2239/ CSA C22.2, STANDARD FOR HARDWARE FOR THE SUPPORT OF CONDUIT, TUBING AND CABLE
This harmonized standard includes tests for resistance to flame propagation, impact and ultraviolet light exposure, as well as for lateral retention.
As a result of the global acceptance of cable cleats, several codes, standards and recommended practices have adopted increased cable restraint performance requirements. Among these documents are API RP14F and RP14FZ, as well as IEEE Standards 45.8, 1185, 1242 and 2740.
Talon® cable cleats have been independently tested in accordance with UL 2239 and IEC 61914, including the tests for axial retention and resistance to electromechanical forces during multiple successive short circuits. Talon® cable cleats comply with the rigorous cable restraint requirements provided in API RP14F, API RP14FZ, IEEE 45.8, IEEE 1185, IEEE 1242, IEEE 2740 and NFPA-70 (NEC).
