Provide users and manufacturers of fittings with definitions of terms, performance requirements, dimensions, test methods and acceptance criteria.

This Standard sets out performance and general requirements for insulator and conductor fittings (other than helical fittings, which are covered in AS 1154.3) together with the critical dimensions for a limited range of insulator pins and cast, forged or fabricated insulator fittings for use on overhead electric power lines using insulators with minimum failing loads of 70 kN, 120 kN and 160 kN. Pulling eyes provided to assist installation and fittings for insulated service lines, aerial bundled cables and high-voltage covered conductors are not covered by this Standard. NOTES: 1 Appendix G provides guidance on means of demonstrating compliance with this Standard. 2 Appendix F provides guidance on items to be specified by purchasers of insulator and conductor fittings.
