3 Terms, Definitions, Acronyms, and Abbreviations For the purposes of this document, the following terms, definitions, acronyms, and abbreviations apply. 3.1 Terms and Definitions 3.1.1 abandoned-in-place Piping system, circuit or contiguous sections thereof meeting all of the following: has been decommissioned with no intention for future use; has been completely de-inventoried/purged of hydrocarbon/chemicals; and is physically disconnected (e.g. air-gapped) from all energy sources and/or other piping/equipment. 3.1.2 alloy material Any metallic material (including welding filler materials) that contains alloying elements, such as chromium, nickel, or molybdenum, which are intentionally added to enhance mechanical or physical properties and/or corrosion resistance. Alloys may be ferrous or non-ferrous based. NOTE Carbon steels are not considered alloys, for purposes of this Code. 3.1.3 alteration A physical change in any component that has design implications affecting the pressure containing capability or flexibility of a piping system beyond the scope of its original design. The following are not considered alterations: comparable or duplicate replacements and replacements in kind.3.1.4 applicable code The code, code section, or other recognized and generally accepted engineering standard or practice to which the piping system was built or which is deemed by the owner/user or the piping engineer to be most appropriate for the situation, including but not limited to the latest edition of ASME B31.3. 3.1.5 authorization Approval/agreement to perform a specific activity (e.g. piping repair) prior to the activity being performed. 3.1.6 authorized inspection agency Defined as any of the following: a) the inspection organization of the jurisdiction in which the piping system is used, b) the inspection organization of an insurance company that is licensed or registered to write insurance for piping systems; c) an owner or user of piping systems who maintains an inspection organization for activities relating only to his equipment and not for piping systems intended for sale or resale; d) an independent inspection organization employed by or under contract to the owner/user of piping systems that are used only by the owner/user and not for sale or resale; e) an independent inspection organization licensed or recognized by the jurisdiction in which the piping system is used and employed by or under contract to the owner/user.3.1.7 authorized piping inspector An employee of an owner/user organization or authorized inspection agency (3.1.6) who is qualified and certified by examination under the provisions of Section 4 and Annex A and is able to perform the functions specified in API 570 where contracted or directed to do so. An NDE examiner is not required to be an authorized piping inspector. Whenever the term inspector is used in API 570, it refers to an authorized piping inspector. 3.1.8 auxiliary piping Instrument and machinery piping, typically small-bore secondary process piping that can be isolated from primary piping systems but is normally not isolated. Examples include flush lines, seal oil lines, analyzer lines, balance lines, buffer gas lines, drains, and vents. 3.1.9 condition monitoring locations CMLs Designated areas on piping systems where periodic examinations are conducted in order to assess the condition of the piping. CMLs may contain one or more examination points and utilize multiple inspection techniques that are based on the predicted damage mechanism(s). CMLs can be a single small area on a piping system e.g. a 2 in. diameter spot or plane through a section of a pipe where examination points exist in all four quadrants of the plane. NOTE CMLs now include, but are not limited to what were previously called TMLs.API 570 pdf download.
