This publication is intended for anyone that uses IP 323 Determination of thermal oxidation stability of gas turbine fuels in laboratories worldwide.

It was developed following an EI technical workshop to review IP 323 tube rating. During the workshop, it was noted many analysts rarely saw IP 323 tube failures and the ratings for marginal pass/fail tubes were highly variable.

This publication provides guidance and assists in the training of analysts on various IP 323 tube deposits and their ratings. It is important when determining the visual rating of used IP 323 tubes that it is carried out exactly as stipulated in IP 323.
