This standard test method establishes two recommended methods for measuring the relativecarburization resistance of alloys for tubes intended for service in ethylene cracking furnaces, orfor assessing the performance of these tubes after service. Application procedures for the twomethods are defined in detail. The combustion analysis method is preferred because it is quantitative. The chemical etching method is simpler and less expensive, but is only semiquantitative. Other methods considered and the reasons they are not recommended are discussed in Appendix A.

This standard is intended to assist designers, operators, producers, fabricators, users, and testinglaboratories in the measurement of the carburization of alloys used for ethylene cracking furnacetubes.
