DOT/OPS adopts API Standard 1104 Nineteenth Edition

DOT/OPS has adopted API 1104 nineteenth edition as matter incorporated by reference in 49 CFR 195 and 49 CFR 192. This edition replaces the eighteenth edition which has been previously incorporated by reference.

The nineteenth edition contains numerous changes from the eighteenth edition. This new edition has been reorganized by a significant breakout of Section 1 into a total of four sections. The remaining sections have been renumbered to reflect the newly added sections. A new Appendix has also been added to cover in-service welding. The nineteenth edition also contains numerous text changes from the earlier edition. Some changes are significant while others are minor. All changes are marked by a vertical bar in the margin.
