PREFACE

This Standard was prepared by the Australian members of Joint Australia/New Zealand

Standards Committee ME-002, Gas Cylinders, to supersede (in part) AS 2030.1—1999, The

verification, filling, inspection, testing and maintenance of cylinders for the storage and

transport of compressed gases, Part 1: Cylinders for compressed gases other than

acetylene. After consultation with stakeholders in both countries, Standards Australia and

Standards New Zealand decided to develop this Standard as an Australian Standard rather

than an Australian/New Zealand Standard.

This edition introduces the following changes:

(a) The main title of the AS 2030 series has been changed and simplified to more

accurately reflect the scope of the Standard.

(b) To clarify the application of the AS 2030 series, the scope of the previous edition of

AS 2030.1 has been divided between this Standard (AS 2030.1) and a new Standard,

AS 2030.5. This edition of AS 2030.1 essentially contains Clauses 1 to 4 and 10 from

the previous edition.

AS 2030.1 applies to all gas cylinders, containing requirements for design,

manufacture and inspection (including conformity assessment), requirements to be

met prior to the first fill and other issues applicable to all cylinders.

AS 2030.5 applies to refillable cylinders (except for acetylene, which remains in

AS 2030.2), and contains additional requirements for filling, inspection (periodic and

non-periodic) and other issues related to refillable cylinders.

(c) Many terms have been re-defined to harmonize with the terminology of the

Australian Code for the Transport of Dangerous Goods by Road and Rail (ADG

Code), which in turn takes its definitions from UN Model Regulations on the

Transport of Dangerous Goods.

Of necessity, some terms have definitions that are not the same as the ADG Code.

Of these the most significant are the following:

(i) This Standard retains the generic term ‘gas cylinder’. The corresponding ADG

Code term ‘transportable pressure receptacle’ is generally equivalent to a gas

cylinder as defined in this Standard, except that a transportable pressure

receptacle may include certain items which are built to a general pressure vessel

code, whereas such items are specifically excluded from the scope of this

Standard.

(ii) This Standard also retains the generic term ‘welded gas cylinder’, rather than

the ADG Code term ‘pressure drum’, because ‘pressure drum’ may include

general pressure vessels.

Appendix C provides a comparison of the definitions used in this Standard,

AS 2030.1—1999 and the ADG Code.

Note that some gases formerly classified as compressed (permanent) are now

classified as high pressure liquefied gases.

(d) Clause 4 from the previous edition has been expanded and clarified to address in

more detail cylinder design and manufacture, manufacturing and inspection, filling

for the first time in Australia, and periodic inspection. Requirements for inspection

bodies now are given, as well as guidance on assessing the competence of design

verifiers.

(e) Requirements for certified gas cylinder test stations (set out in AS 2337.1) have been

clarified and some associated terminology has been updated to reflect current issues.

The terms ‘normative’ and ‘informative’ have been used in this Standard to define the

application of the appendix to which they apply. A ‘normative’ appendix is an integral part

of a Standard, whereas an ‘informative’ appendix is only for information and guidance.

IT SHOULD BE NOTED THAT COMPLIANCE WITH THIS STANDARD MAY

NOT NECESSARILY FULFILL ALL LEGAL OBLIGATIONS.

FOREWORD

This revision of AS 2030 continues a tradition of more than 75 years, since the original

release of AS CB4—1931, of setting out technical requirements for the design, type testing,

verification, manufacturing, inspection, documentation and filling of gas cylinders.

The Standard reflects the considerable body of experience accumulated over the years by

the compressed gas industry and codified by the Australian members of Standards Australia

Committee ME-002, Gas Cylinders. Together with its many subordinate standards,

especially AS 2337.1—2004, Gas cylinder test stations, Part 1: General requirements,

inspection and tests—Gas cylinders, AS 2030 has specified and documented a voluntary

technical working model for gas cylinders in Australia.

Over this period, the regulatory environment for gas cylinders has evolved considerably, as

has the relationship between regulations and this Standard. The most significant current

regulations are probably the National Standard for Plant [NOHSC:1010(1994)], the

Australian Code for the Transport of Dangerous Goods by Road and Rail (ADG Code), and

the local regulations which implement these in the various states and territories.

These regulations and codes may refer to AS 2030 for technical specifications and details.

Despite these references, AS 2030 remains a technical standard limited to setting out

specifications, test methods and in general providing a technical model for gas cylinders

requirements.

The regulations and codes specify requirements which may be covered partially or not at all

in AS 2030. Conversely, not all the AS 2030 requirements may lead to action by the

regulatory authorities. This applies particularly to the requirements for the manufacture and

manufacturing inspection of gas cylinders outside Australia.

Hence, users of AS 2030 should be fully aware that implementation of this Standard’s

specifications and guidelines is totally outside its jurisdiction, and they need to refer to the

relevant regulations and codes to determine their responsibilities and obligations.

It cannot be emphasized too strongly that compliance with this Standard may not

necessarily fulfil all legal obligations.

Gas cylinders


1 SCOPE

This Standard specifies requirements for the design, verification and manufacture of all gas

cylinders for the storage and transport of compressed, dissolved and liquefied gases, of

water capacity ranging from 0.1 kg to 3000 kg.

AS 2030.2 sets out additional requirements for compressed dissolved acetylene.

NOTE: Designation AS 2030.3 is currently not in use.

AS 2030.4 sets out additional requirements for closed cryogenic receptacles (formerly

called insulated welded cylinders).

AS 2030.5 sets out additional requirements for the filling, inspection and testing of

refillable gas cylinders, except cylinders for dissolved acetylene and closed cryogenic

receptacles.

This Standard does not apply to:

(a) Cylinders forming part of aircraft equipment and used solely in aircraft other than as

a reference made in a direction pursuant to the Civil Aviation Regulations.

(b) Aerosol containers and gas cartridges.

(c) Non-refillable cylinders.

The requirements for gas cylinders in fire extinguisher systems and fire extinguishers, apply

only where suitable requirements are not given in another Australian Standard.

NOTES:

1 The term ‘cylinder’ is used interchangeably with ‘gas cylinder’ in this Standard.

2 Whilst this Standard is written for application to gas cylinders, some of its requirements are

referenced by Standards related to pressure vessels (e.g. automotive fuel vessels for LP Gas).

2 REFERENCED DOCUMENTS

A list with titles of the documents referred to in this Standard is given in Appendix A.

3 DEFINITIONS

For the purpose of this Standard and all parts of AS 2030, the definitions below apply.

3.1 Aerosol container

Non-refillable container meeting the requirements of AS 2278 or an equivalent foreign

Standard.

3.2 Bundle

An assembly of cylinders, each of water capacity less than 150 kg, fastened together and

interconnected by a manifold and intended to be transported as a single unit.

NOTES:

1 Such assemblies were previously referred to as a ‘manifold pack’.

2 Limits to the water capacity for the transport of a bundle may apply under the ADG Code.

1 It is recommended that the thread designation (e.g. 25AU, 25E, 3/4NGT), be stamped on

the cylinder.

2 Adaptors between cylinder neck threads and valves are considered to be hazardous due to

the risk of leakage and inadvertent separation. Adaptors are used in the Australian

Department of Defence systems, where close control of the system is provided for. Use of

adaptors in other systems is to be avoided.

The manifold between the cylinders and the common gas outlet valve of a bundle is not

considered to be an adaptor.

6 ADDITIONAL REQUIREMENTS PRIOR TO FILLING FOR THE FIRST TIME IN

AUSTRALIA

6.1 Initial test station inspection and marking

Each cylinder shall be inspected by a test station prior to filling for the first time in

Australia, in accordance with AS 2337.1 and other applicable Parts of AS 2337.

The test station shall be certified for the inspection and testing of cylinders according to the

requirements of AS 2337.1, and additionally to those Parts of AS 2337 that are relevant to

the type of cylinder being tested.

The certification body shall be independent of the test station, and shall be accredited by

JAS-ANZ or an equivalent body to grant certificates of conformity to test stations according

to the relevant Parts of AS 2337.

NOTES:

1 The presence of a design registration number on a cylinder may subsequently be used as

evidence that the design verification requirements have been met.

2 The presence of the first test station mark may be used at subsequent inspections and tests as

evidence that the cylinder meets the specified design and construction requirements.

3 An informative list of stamp marks, which have been assigned to certified test stations by

certification bodies, is published as MP 48.

6.2 Completion of a cylinder package

Additional preparation for the cylinder to be fit for filling for the first time in Australia, e.g.

fitting of cylinder valve, safety devices, valve protection and marking, shall be carried out

in accordance with the requirements of the cylinder Standard, of this Standard, and of the

other applicable Parts of AS 2030.

7 PERIODIC INSPECTION AND TESTING

Cylinders shall be subjected to periodic inspection and testing by a test station which

complies with Clause 6.1. Periodic inspection and testing shall be performed in accordance

with the requirements of the relevant Parts of AS 2030, of AS 2337.1, and of the other

8 CARE AND HANDLING

8.1 General

A gas cylinder should always be presumed to contain pressure, even when gas is not

released when the valve is opened.

Cylinder valves shall not be disassembled nor removed from a cylinder, except by qualified

personnel and with the permission of the cylinder owner.

8.2 Storage, handling and transportation

A gas cylinder shall only be used for the storage and transport of gases and substances for

which it was designed.

NOTES:

1 For storage and handling of gas cylinders, the following Standards provide guidance:

AS/NZS 1596, AS 3848 Parts 1 and 2, AS 4289, AS 4332, AS 4839, AS 5034 and ISO 11625.

2 For transport, reference should be made to the ADG Code, and to relevant State, Territory and

Commonwealth regulations pertaining to dangerous goods and/or hazardous substances.

8.3 Avoidance of oil, grease and water

Neither oil nor grease shall be allowed to come into contact with the valves or cylinders

used for the storage and transport of any gas. Particular care shall be taken to prevent

contamination of any cylinder which contains oxygen, nitrous oxide, chlorine, any other

oxidizing agent or any gas for human respiration.

Care shall be taken to ensure that water is not allowed to enter a cylinder between

hydrostatic test or inspections.

NOTE: Exclusion of moisture and other potentially corrosive materials is particularly important

for cylinders manufactured from high strength steel where the relatively thin walls provide little

corrosion allowance.

8.4 Closing valves for transportation

The shut-off valve for each cylinder shall be closed during transportation.

8.5 Cylinders for toxic gases

A gastight seal shall not be removed from a toxic gas cylinder unless appropriate protection

(e.g. personal protective equipment) is afforded to the person(s) removing the seal. While

the seal is being removed, a check for leakage shall be carried out.

8.6 Need to keep cylinders cool

Filled cylinders shall be kept away from sources of heat which are likely to overheat the

cylinder, above its maximum working temperature.

8.7 Avoidance of shock

Cylinders should not be allowed to fall upon one another or be otherwise subjected to undue

mechanical shock. During transport and use, cylinders shall be secured.

8.8 Correct orientation

Cylinders filled with liquefied gas shall be transported, stored and used in a manner which

ensures that the safety device is in direct contact with the vapour space.
