It is important to note that any organisation or persons carrying out refilling of gas cylinders should do so in accordance with EN 1920. This standard covers requirements which reflect current practice and experience such that each transportable gas cylinder is inspected at the time of filling in order to establish that:

  •  It has no defects such that the cylinder is unsafe for filling, requires testing or is unsafe for continued use.
  •  It can be identified and complies with the relevant requirements with regard to marking , labelling, colour coding and completeness of its accessories.
  •  Its valve functions satisfactorily.

Diving Cylinder Inspection and Testing

Under new EU legislation, the testing and inspection of cylinders used in conjunction with diving came into operation as of July 1st 2006. From that date CFT as the national governing body for diving in Ireland are no longer able to inspect, certify and approve test houses which previously carried out this work. Since that date all test houses carrying out inspection and testing of diving cylinders in Ireland are now part of the IDEST (Inspectorate for Diving Equipment Service & Testing) organisation and are accredited under UKAS approval for such activities. A list of these test houses in Ireland can be seen at

Please note that all VIP labels previously issued by CFT up to June 30th, 2006 will remain valid until their expiry date i.e. a VIP label issued on June 30th, 2006 will remain valid until December 2008. Only accredited test houses can inspect test and issue cylinder inspection labels. If a diving cylinder does not bear an IDEST inspection cylinder then it has not been tested according to legislation and will not be filled by a compressed air station.

Industrial Pressure Testing Limited has been an IDEST test house since 1997 and has a registered test house mark for diving cylinders of 3R which is stamped on all diving cylinders after inspection and/or retest.

A diving cylinder must be inspected must be visually inspected every two and a half years and be retested every five years from its date of manufacture.

Composite Cylinders

Fully wrapped carbon composite cylinders are among the lightest gas cylinders available for general high pressure applications and are now in use world wide. These types of cylinders meet the needs of many end users in breathing apparatus, escape sets , medical support and anywhere portability is important.

It is important to understand the following:

  • All cylinders manufactured to HSE-AL-FW2 and EN 12245 (CE marked) require testing every 5 years from the date of manufacture.
  • Cylinder life spans remain at 15 years and CANNOT under any circumstances be extended.
  • As part of EN ISO 11623 the expiry date of composite cylinders must clearly be marked with the letters“FINAL” followed by the year (four figures) and the month (two figures).
  • At IPT Ltd, we operate a policy of placing a sticker on the neck of each cylinder containing the retest date. The orange “FINAL” sticker on the cylinder neck will contain the withdrawal date of the cylinder. This enables the BA officer to easily identify cylinders. This information will also be found on the cylinder body.
  • Some cylinders will not be tested to a 5-year cycle, as the 15-year life span will take precedence.
  • Cylinders that have reached their 15-year life span must be removed from service. A destruction certificate may be issued if requested by the customer.
  • All Sabre and Dräger B.A. cylinder valves must be serviced at the time of cylinder test.
  • As of July 2006, only Approved Bodies can inspect composite B.A. cylinders. No other organisations or companies can test compressed gas cylinders. IPT Ltd., is the only Nationally Accredited company currently in discussion with The Health and Safety Authority to achieve Approved Body status. Until such time IPT Ltd., is accredited by I.N.A.B. to continue testing composite B.A. cylinders. (see I.N.A.B. web site-Directory of Accredited Inspection Bodies)

Accredited Test Certificates or Certificates of Destruction are issued for each cylinder. IPT Ltd is the only current Nationally Accredited test station operating all aspects of the relevant standard.
