  • block-to-hook adapters;
  • connectors and link adapters;
  • drilling hooks;
  • tubing hooks and sucker-rod hooks;
  • elevator links;
  • casing elevators, tubing elevators, drill-pipe elevators and drill-collar elevators;
  • sucker-rod elevators;
  • rotary swivel-bail adapters;
  • rotary swivels;
  • power swivels;
  • power subs;
  • spiders, if capable of being used as elevators;
  • wire-line anchors;
  • drill-string motion compensators;
  • kelly spinners, if capable of being used as hoisting equipment;
  • pressure vessels and piping mounted onto hoisting equipment;
  • safety clamps, if capable of being used as hoisting equipment;
  • guide dollies (annex B).

This International Standard establishes requirements for two product specification levels (PSLs). These two PSL designations define different levels of technical requirements. All the requirements of clause 4 through clause 11 are applicable to PSL 1 unless specifically identified as PSL 2. PSL 2 includes all the requirements of PSL 1 plus the additional practices as stated herein.

Supplementary requirements apply only when specified. Annex A gives a number of standardized supplementary requirements.
