Specifies requirements for arresting systems in vertical shaft friction winding installations, including materials, design and testing. Appendices provide guidelines on information to be provided by the purchaser and the supplier, and on the arrestor operating distance.

This Standard specifies requirements for arresting systems in vertical shaft friction winding installations.This Standard does not apply to vertical shaft drum winding installations and it makes no provision for an arrest at a velocity greater than the maximum entry velocity.NOTE: Appendices A and B give guidelines on information to be provided by the purchaser and the supplier. Appendix C gives guidelines on the design requirements for an arresting system.
