Gas Cylinder Test Station – AS 2337

The Gas Cylinder Testing Station Scheme details requirements and procedures for certification against the gas cylinder standards series AS 2337

Overview of Scheme: 
The AS 2337 series of standards provides test station owners with the requirements and procedures to carry out initial and periodic inspections to comply with regulatory needs. DNV certifies test stations to obtain a certificate of conformity to test cylinders of various types including:

  • AS 2337.1 2004 – Welded and brazed (BBQ, camping and other types of LPG cylinders other than automotive), Seamless (CO2 fire extinguishers and SCUBA Cylinders)
  • AS 2337.2 2004– Automotive LPG (LPG fuel vessels for cars), Automotive CNG (natural gas fuel cylinders for trucks and buses)
  • AS 2337.3 2006 – Composite (Fibre reinforced plastic and self-contained breathing apparatus SCBA)

GCTS Certifications provides test station owners and consumers with confidence that the product is safe – certificates of conformity will be issued when all conditions are met.

GCTS Certification is based on onsite document review, workplace and equipment adequacy and signatory assessments. Test Station Manager and Nominated Signatories are subject to an assessment on the applicable standards and the names of the competent personnel are published on the Certificate of Conformity as signatories. GCTS Certiifcation allows the test station mark to be applied.

Test stations are certified for different modes of operation:

  • Static Test Station – Located at a permanent address.
  • Mobile test station – Vehicle based station or Portable station
  • New Cylinder / Auto Vessels only

DNV Tests To The Following Standards:

  • AS 2030.1 2009: The verification, filling, inspection, testing and maintenance of cylinders for storage and transport of compressed gases
  • AS2337.1: General requirements, inspections and tests—Gas
  • AS2337.2: LP Gas fuel vessels for automotive use
  • AS2337.3: Gas cylinder test stations
  • Welded and brazed: BBQ, camping and other types of LPG cylinders other than automotive
  • Seamless: SCUBA, CO2 fire extinguishers
  • Composite: Previously known as fibre reinforced plastic and breathing apparatus
  • Automotive LPG: LPG fuel vessels for cars
  • Automotive CNG: Natural gas fuel cylinders for trucks and buses

Gas Cylinder Test Station Mark

The test mark indicates that the cylinder has been designed, design-registered, inspected, tested and can be legally filled or refilled in accordance with Australian Standard AS 2030. The test mark is only current if the periodic inspection interval since the most recent inspection date has not been exceeded. Periodic inspection intervals for retesting different cylinder types are listed in AS 2030.5. Examples of periodic inspection intervals are:

  • SCUBA cylinders = 1 year
  • Steel cylinders without residual pressure valves, filled with CO2 = 5 Years
  • Aluminium cylinders filled with CO2 = 10 Years
  • Welded cylinders less than 100 kg water capacity filled with LPG (typically connected to barbecues) = 10 Years
