Free download api 1104 21st edition4/16/2024 ![]() ![]() Two PQRs written for tests on welds made using different welding processes cannot be used to support a new WPS that includes the use of multiple welding processes. Not all welding methods are applicable to all welding processes. Welding methods (or methods of application) include manual, semiautomatic, mechanized, or automatic, and combinations of these methods. What does method of application mean?Įight possible welding processes are listed in Section 1 (of API 1104). PR-186-124502-R01)from which responses follow:Īs per 5.4.2.1 a change in the welding process or method of application has to be considered as an essential variable. As I said above, if you use the most stringent regulations (Sections) that are Incorporated By Reference you should be safe and in compliance with both agencies.PRCI publishes the "Guidelines for Interpretation and Application of API 1104 – Twenty-first Edition" (Catalog No. I believe it is usually the same for some States after they adopt it but there may be a time lag between the Feds and State in adopting the Standard. I believe DOT allows either 3 or 6 months after it is incorporated. If you want to know the date when you must stop using one edition and change to the other it depends on which regulatory agency you talk to. Compliance is required for "certification" or "stamping" of products manufactured in accordance with their requirements and these products must be manufactured in accordance with the latest editions. Some organizations such as ASME and API do have provisions for requiring compliance with their Standards. ![]() In other cases DOT simply did not have time to review and Incorporate those editions. Occasionally the 1104 Committee has referenced different sections of the 1104 in sections that were Incorporated By Reference by DOT and this was where objections were raised. At times DOT did object to certain portions of the 1104 and did not Incorporate that edition. Jumping ahead to use portions of the Standard may be futile if the edition is never incorporated. ![]() I could be wrong on the 12th edition however. It seems as though editions 12, 14, and 16 were never Incorporated. Understand that not all editions of the API 1104 were Incorporated by DOT. If it is your choice or if your requirements are that you use the latest edition there is no problem with that as long as you satisfy all the requirements of the current Incorporated By Reference edition. As long as you are using the most strict requirements from either standard you should be safe. Sometimes state regulators may lag behind the Feds a little bit, but keep in mind that the Feds always trump the State. And as you mentioned your State regulations may also list of approved codes and standards. ![]() Review relevant DOT parts and the API 1104 to see which Sections are referenced and within the 1104 which Sections may be referenced. Not all of API 1104 is Incorporated By Reference. Continuing to use an edition that has been replaced by a more current edition is not typically frowned upon as long as any additional work is in compliance with the current Incorporated edition. Currently as of Januthe 20th edition of API 1104 is still the listed edition therefore it is required that this edition be used for any work that is covered by DOT. DOT CFR Part 192 and 195 has lists of documents that have been Incorporated By Reference (be sure to read the explanation of what Incorporated By Reference means). ![]()
