scope:

The scope of this recommended practice is the use and limitations of ßame arresters installed in piping systems in the petroleum and petrochemical industries. It provides a general overview of ßame arresters currently in use and some potential concerns or limitations. Applicable combustion and ßame propagation parameters are discussed including the distinction between arresting ßames versus arresting detonations.

This recommended practice is neither a design manual nor a regulatory compliance document. It does provide reference to more detailed technical discussions of ßame arresters and combustion. Various standards, codes, and regulations are noted in the Section 2 references and in the Appendix A Bibliography.
