AS2885.0 Section 1.5


Are definitions (Defined Terms) in line with both Regulator and Legal Counsel? Were these tested?

(Peter Tuft) Short answer - no, definitions were not tested with legal advice. Longer answer: Because AS 2885 is used in multiple jurisdictions, it is not possible to ensure perfect consistency with every one of them. The best we have been able to do is endeavour to avoid any inconsistency, and to be internally consistent within the Standard.


If a Defined Term conflict currently occurs between Parts while we’re waiting on the latest AS2885 part releases, which Standard should take precedence?

(Susan Jaques) The AS2885.0 (Part 0) defined term takes precedence.

Some examples below. Applying the Part 0 (2018) definitions of these is an improvement and not really a conflict.

Test Signatory - replaces Supervising Test Engineer in Part 5.

Land Use Change vs Encroachment : these terms are currently conflated in the 2012 version of Part 3, but the defined terms should be adopted asap for clarity.


By definition, a defect is rejectable flaw. Is it still repairable?

(Peter Tuft) See Clause 11.5 of Part 1 "Repair of Pipe Defects": you can repair by grinding, fitting a sleeve or, cutting it out.


Should we have a definition for "Pipeline Failure" (e.g. loss of containment including leak or rupture).

(Peter Tuft) AS2885 uses the term Failure Event to define loss of containment. A failure event by definition also includes restriction or shutdown of supply that affects a community.

The word "failure" is used in various places through the Standard in its common English sense so we needed different terminology (ie, failure event) for when we want to refer to the narrowly defined meaning.


What is the extent of authority over pipeline easements near new homes? Some pipelines are running through driveways of new estates.

(Peter Tuft) An actual easement is defined legally and on the title of property over which it exists, and gives rights to the holder of the easement to do certain things with the land despite not being the landowner. So if an easement exists, the answer to the question is to look at the easement documentation.

Not all pipelines have a formal easement. AS2885 now defines Pipeline Corridor as the pipeline easement or equivalent, with a note saying that in the absence of a formal easement, the pipeline corridor is a minimum of 3 m but preferably 6 m either side of the pipeline. But that would have no legal status if there is no actual easement.
