scope:

The purpose of this part of IEC 61300 is to describe the procedure required to measure the gauge pin withdrawal force for rectangular ferrule multi -fibre connectors. This measurement can be used as an alternative to the measurement of the gauge pin insertion force, both of which evaluate the fit of the gauge pin(s) into the guide pin hole(s) of the female-type connector. The experimental verification of interchangeability between them is shown in Annex A. For the male-type connector, IEC 61300-3-49, Guide pin retention force for rectangular ferrule multi-fibre connectors, is applied to evaluate how securely the guide pins are retained in the guide holes.
