This International Standard specifies the technical delivery conditions for corrosion-resistant alloy seamless
tubulars for casing, tubing and coupling stock for two product specification levels:
- PSL-1, which is the basis of this International Standard;
- PSL-2, which provides additional requirements for a product that is intended to be both corrosion resistant
and cracking resistant for the environments and qualification method specified in ISO 15156-3 and
Annex G of this International Standard.
At the option of the manufacturer, PSL-2 products can be provided in lieu of PSL-1.
