This compendium describes each ASME standard referenced in 49 of the Code of Federal Regulations (CFR) Part 192, 49 CFR Part 193, and 49 CFR Part 195. For each 49 CFR Part the referenced ASME standard will be identified and, in the case of ASME B31.8S and certain other ASME standards, the relevant text will be included in this compendium.

It is intended that the reader of this compendium document will be initially reviewing the federal pipeline safety regulations and then reviewing the referenced ASME standard. This compendium document has been structured to facilitate this usage pattern.
