L52306 Guidelines for Interpretation and Application of API 1104

The application of requirements contained in many industry codes and standards requires some interpretation by the user and by the regulator who is called upon to enforce their use. There are often differences in the way requirements are interpreted because of unclear rationale behind the requirements or novel or non-traditional applications. Some industry codes and standards contain guidance in the form of commentary sections or companion documents. This is not the case for API Standard 1104 - Welding of Pipelines and Related Facilities, where requests for interpretation are common because of unclear requirements or an absence of information pertaining to rationale. Since API 1104 is written in the form of a specification, it cannot present background information or discuss the intent of the API 1104 committee.

The result of this project was the development of interpretation and guidance material for API 1104.
