Crimping of flexible cord conductors

PG
Like most of us, I often crimp flne strand conductors, especially for screw terminals but do not do this for domestic lamp holders and roses etc.

I thought that I would check Section 526 (Electrical Connections) of the Regs but did't find a clear statement of requirements for crimped ends. 

I was particularly unsure of what 526.9.1 was specifying for fine wire conductors "conductor ends shall be suitably treated".


Any guidance or comment would be appreciated.

    My world was originally aircraft electrical wiring. The main thing to remember with crimps and ferrules is to match (as best you can) crimp tools to product/conductor type and manufacturer.

    Easily done in aviation engineering because of the control standards in place, not so easy in general electrical installation.

    A general rule in my view DO NOT use a not ratchet controlled crimper. That is a good starting place.

    The term 'shear it and back a turn' springs to mind!
