Cylinder Test Periods

16th July, 2002

BS 5430 PARTS 1 & 3 WITHDRAWN
On March 25th BS 5430 Parts 1 and 3, which concern the testing of cylinders, were withdrawn and replaced by two new European standards.
BS 5430 Part 1 has been replaced by BS EN 1968:2002 (steel cylinders) and Part 3 has been replaced with BS EN 1802:2002 (aluminium cylinders). In view of the lack of guidance from either HSE or BSI, IDEST have advised their approved test houses to implement the new standards by 31st August 2002.

Changes:
  • The test periods have changed from four years to 5 years and inspection period from two years to 2.5 years.
  • The cylinder must have the test date stamped on it, as before, but also have a stick-on label stating the date of the next test.
  • The 'intended contents' must also be clearly shown on the cylinder, such as Breathing Air, Nitrox or Trimix.
Any cylinders tested on the preceding standards should allow the certificate to run out and then be tested in compliance with the new standards; they should not extend their validity period.
These changes are to bring diving cylinders in line with the 10 year statutory testing for industrial gas cylinders.
These new standards now refer readers to other British Standards for guidance on stamping, labelling and colour coding of cylinders.
