Types of Inspection and Testing of Containers:

Default Revisions

… is carried out before putting the container into operation. A review report, which is an attachment of the passport, must be written about the result.

Operational revisions

… shall be carried out within two weeks after the start of the operation of the pressure receptacle and the others at regular intervals not later than one year after the previous operation. Providing regular operational revisions is the responsibility of the pressure vessel operator. These regular operational reviews are also carried out in agreement with the customer.

Operational revisions shall be checked in particular:

  1. the general condition of the container, the security equipment of the regulating shut-off and locking devices, the measuring instruments,
    whether the equipment referred to in point 1 is maintained, checked and documented
    way of operation
  2. cleanliness and order around the container and safe access to containers
  3. whether the production labels are legible and undamaged
  4. whether the operator meets the conditions of Article 6 of the Annex

Internal Revisions:

… shall be carried out within a period of no more than 5 years, taking into account the structure, condition and age of the vessel, the operating medium and special operating conditions. The condition of the container on the outside and inside, including all outlets and kits, is judged.

Leak test

… is carried out after each internal inspection by an overpressure. It is usually done hydraulically or pneumatically.

Pressure test


… shall be carried out at least once every 9 years from the previous pressure test with a test overpressure. It is usually done with water or other non-flammable liquid and that:

  • after each repair or reconstruction
  • after a break of more than 2 years if this is deemed necessary on the basis of an internal review
  • after displacement of the container, if this is required by the internal inspection after the maximum operating
  • pressure has been exceeded or the temperature at which the quality of the material or the mechanical properties of the container wall material may have deteriorated.
