General

Gauging, calibrating and adjusting - all have something to do with accuracy and measurement. However, the way in which this is done and the accuracy that can be achieved are very different.

The information in this document is to be used only as a guide to select equipment for appropriate chemical compatibility.

There are two major criteria to assess the corrosion resistance against salt water of a stainless steel based on material specifications: PREN Pitting Resistance Equivalent Number and CPT Critical Pitting Temperature, both depending on the contents of the material. For practical tests, a good and reliable indication is the salt mist test according IEC 60068-2-52:1996.
