This Standard specifies general requirements for the design, construction, 
testing, maintenance and inspection of road tank vehicles, irrespective of 
the cargo, that are intended for the road transport of dangerous goods.


//  Preface


GOAL RULE Preface PROVIDES
This Standard was prepared by the Standards Australia Committee ME-057, 
Road Tank Vehicles for Dangerous Goods, to supersede AS 2809.1—2008, 
Road tank vehicles for dangerous goods, Part 1: General requirements. AND
The objective of this Standard is to provide designers, planners, operators 
and regulators with technical requirements for road tank vehicles 
transporting dangerous goods.
AND This Standard specifies general requirements for all road tank vehicles. AND
Additional specific requirements applicable to particular road tank vehicles 
are detailed in the appropriate part of the AS 2809 series on road tank 
vehicles, which comprises six parts.
AND The major changes in this edition are as follows:
(a) Duplicate clauses on maintenance and multiple tank types from other 
parts of the AS 2809 series have been amalgamated in this Standard.
(b) Terms and definitions have been added, improved, and amalgamated from 
other parts of the AS 2809 series, into this Standard.
(c) Design and electrical provisions have been revised and amalgamated from 
other parts of the AS 2809 series into this Standard.
(d) The static roll-over threshold (SRT) method for stability has been 
included.
(e) Appendix B has been aligned with current practice.
AND This Standard is intended to serve as a reference Standard for industry and 
for the various statutory authorities administering regulations for the safe 
design and maintenance of dangerous goods road tank vehicles.
AND The wording of the title and scope have been chosen to align with the 
Australian Dangerous Goods (ADG Code).
AND Authorities and regulations may affect the use of this Standard.
AND Conformance with this Standard does not fulfil all legal obligations.
AND Designers, manufacturers and importers have a legal obligation to ensure, 
so far as is reasonably practicable, that plant and equipment is without
risks to health and safety to workers throughout its life.
AND The terms “normative” and “informative” are used in Standards to define the 
application of the appendix to which they apply.
AND A “normative” appendix is an integral part of a Standard
AND An “informative” appendix is only for information and guidance
